1. Basic Calculations
Required bearing size is determined by the action of the external forces and according to the
bearing required life and its reliability in the arrangement. Magnitude, direction and kind of load
acting on the bearing, as well as the operating speed, are decisive for the type and bearing size
selection. Other special or important conditions of each individual arrangement must be taken
into account, e.g. operating temperature, limited space availability, simplicity of mounting,
lubrication requirements, sealing, etc., and all of these can influence selection of the most suitable
bearing. For given concrete conditions various bearing types can meet those requirements.
From the point of view of outer load acting and the bearing function in respective arrangement
or unit we distinguish two types of the rolling bearing load in the bearing technique :
- when rolling bearing rings are relatively rotating against each other and bearing is under outer
load (which is valid for most bearings), this is called dynamic bearing load,
- when rolling bearing rings either do not move against each other or they move only very
slowly, the bearing carries an oscillating motion or the outer load acts for a shorter time than one
bearing revolution, this is called static bearing load.
For bearing safety calculation, the life limited by bearing breakdown due to material fatigue of
a bearing component is decisive in the first case. In the second case there are durable
deformations of functional surfaces on the contact surfaces of rolling elements and raceways.
1.1 Dynamic Load
1.1.1 Basic Dynamic Load Rating
Basic dynamic load rating is a constant invariable load which the bearing can theoretically carry
at the nominal life of one million revolutions.
For radial bearings, the radial dynamic load rating Cr refers to constant load. For thrust bearings,
the axial dynamic load rating Ca refers to unvariable, purely axial load, acting centrically.
Basic dynamic load ratings Cr and Ca, whose size depends on bearing dimensions, rolling
element number, material and bearing design, are shown for each bearing in the dimension tables.
Values of the basic dynamic load ratings were stated according to the standard STN ISO 281.These
values are verified in testing equipments and by operation results.
1.1.2 Life
Rolling bearing life is defined as the number of revolution carried out by one bearing ring against
the other ring, until the first signs of material fatigue occur on one ring or the rolling element.
Great differences in life can occur among bearings of the same type, that is why according to
the standard STN ISO 281 the basic life is used as the basis for life calculation, i.e. life shown by
the operation time attained or exceeded by a bearing group at 90% reliability.
Life Equation
Nominal bearing life is mathematically defined by the life equation valid for all bearing types.

υ - kinematic lubricant viscosity by operation bearing temperature
[mm2.s-1]
υ1 - kinematic viscosity for defined rotational speed
and selected bearing dimensions
[mm2.s-1]
Values υ and υ1 are determined according to the diagrams in Pict. 23 or 24.
In the diagram, Pict. 1, the line I is valid for radial ball bearings operating in a very clean
environment. In other cases the factor a23 is lower, depending on the environment cleanliness, and
the decreasing tendency is dependent on the bearing design group in following order :
- angular contact ball bearings
- tapered roller bearings
- cylindrical roller bearings
- double row self-aligning ball bearings
- spherical roller bearings
Line II can be used when stating the factor a23 for spherical roller bearings operating in a dusty
environment.

1.1.3 Equivalent Dynamic Load
In the arrangement the bearing is subjected to generally acting forces in various magnitudes, at
various rotational speeds and with different acting period. From the point of view of calculation
methodology the acting forces should be re-calculated into the constant load, by which the
bearing will have the same life as it reaches in the conditions of the actual load.
Such a re-calculated constant radial or axial load is called the equivalent load P, or Pr (radial) or
Pa (axial).
Combined Load
Constant Load
The outer forces acting on a bearing are not changed both from the point of view of size and
time dependence.
Radial Bearings
If the radial bearings are simultaneously subjected to constant forces in radial and axial
directions, the following equation is valid for calculating the radial equivalent dynamic load :
Pr = X.Fr + Y.Fa

Factors X and Y depend on the ratio Fa/Fr. Values X and Y are shown in the dimension tables or
in the introduction to each bearing type where closer information regarding bearing calculation of
the respective type is given.
Thrust Bearings
Thrust ball bearings can carry only forces acting in axial direction and the following equation is
valid for calculating axial equivalent dynamic load :
Pa = Fa
Pa - axial equivalent dynamic load
Fa - axial bearing load
[kN]
[kN]
[kN]
Spherical roller thrust bearings can also carry some radial load, but only by simultaneous acting
of axial load, when condition Fr 0.55 Fa must be fulfilled. Axial equivalent dynamic load is
calculated from equation
Pa = Fa + 1.2 Fr
[kN]
Fluctuating Load
Real fluctuating load, whose time course we know, is for calculation replaced by mean
hypothetical load. This hypothetical load has the same influence on the bearing as the fluctuating
load.

Change of Load Magnitude by Constant Rotational Speed

1.1.4 Temperature Influence
Delivered bearing assortment is determined for usage in an environment with operating
temperatures up to 120°C. Exceptions are double row spherical roller bearings which can work at
temperatures up to 180°C, and single row ball bearings with seals (RS, 2RS, RSR, 2RSR) applicable
up to 110°C, with seals RS2, -2RS2 applicable up to 150°C.
For higher operation temperatures the bearings are produced so that their necessary physical
and mechanical qualities and dimensional stability can be secured.
Values of the basic dynamic load ratings Cr or Ca shown in the dimension tables of this
publication should be multiplied by factor ft, shown in Table 7.

bearing in the dimension tables of this publication. Values Cor and Coa were stated by a calculation
according to the standard STN ISO 76.

heavily loaded contact zone of the rolling element and bearing raceway :
- 4 600 MPa for double row self-aligning ball bearings
- 4 200 MPa for the other ball bearings
- 4 000 MPa for cylindrical roller, needle roller, spherical roller and tapered roller bearings

1.3 Limiting Speed
Limiting speed depends on the bearing type, its accuracy, cage design, internal clearance,
operating conditions in arrangement, kind of lubrication and on other factors. This influence
summary determines the heat generation in the bearing and also limited rotational speed which is
first of all limited by the lubricant operating temperature.
For orientation, limiting rotational speed values are shown in the dimension tables for individual
bearings in normal tolerance class, both for grease and oil lubrication.Given values are valid under
presumption of adequate load (L10h 100 000 h), normal operating conditions and cooling.
It is also necessary to reduce the limiting speed values for radial bearings which are permanently
loaded by relatively great axial force.The resulting limiting speed values depend on the ratio of
axial and radial load Fa/Fr.
The shown limiting speed can be exceeded for ball bearings up to 3 times, cylindrical roller
bearings up to 2 times, for other bearings except spherical roller and tapered roller bearings up to
1.5 times and for spherical roller bearings 1.3 times.

This exceeding requires :
- adaptation of lubrication and cooling
- higher bearing tolerance class and coresponding accuracy of the abutment parts
- higher radial clearance than normal
- cage of suitable design and material
2. Rolling Bearing Design Data
2.1 Boundary Dimensions
Bearings introduced in this publication are made in dimensions complying with the international
standards ISO 15, ISO 355 and ISO 104.
In the dimensional plan each bearing bore diameter d corresponds to several outer diameters
D and various widths are added to them – B or T for radial and H for thrust bearings. Bearings
having the same bore diameter and outer diameter belong to one diameter series which is
designated according to the ascending outer diameter by figures 7,8,9,0,1,2,3,4. Within each
diameter series there are bearings of various width series according to the ascending width : 8, 0,
1, 2, 3, 4, 5, 6 for radial bearings and 7,9,1,2 for thrust bearings. Diameter and width series form
dimension series which are designated by a two digit number, where the first digit indicates the
width series and the second the diameter one, as shown in Pict. 7.
Some standard and special ZKL bearings in 3D visualization will be found on

2.2 Designation
Bearing designation is created by numerical and letter symbols indicating the type, size and
design of the bearing, see the scheme.
In the basic design the bearings are designated by a basic designation which consists of bearing
type and size designation. The type designation is usually created by the symbol indicating the
bearing design (see position 3 in the scheme) and the symbol for dimension series or diameter
series (positions 4 and 5 in the scheme), e.g. bearing type 223, 302, NJ22, 511, 62, 12, etc. Bearing
size designation is created by symbols for the nominal bore diameter d (see position 6 in the
scheme).
Bearings with bore diameter d<10 mm :
Digit separated by a slash, or the last digit indicates directly the bore dimension in mm,
e.g. 619/2, 624.

Bore diameter is a fivefold of the last double digit number, e.g. bearing 1320 has the bore
diameter d = 20 x 5 = 100.
An exception create bearings with bore d = 22, 28, and 32 mm, where the double digit number
separated by a slash indicates directly the bore diameter in mm, e.g. 320/32AX, further separable

C06 reduced vibration level lower than C6, e.g. 6205 C06
C66 reduced vibration level lower than C06, e.g. 6205 C66
Concrete C06 and C66 values are determined after negotiaitions between customer and supplier.
Note: Bearings in tolerance class P5 and higher have vibration level C6.
Increased Operation Safety
C7, C8, C9 - bearings with increased operation safety determined primarily for aircraft industry,
e.g. 16008 C8
Symbol Combination (12 - 15)
Symbols for tolerance class, bearing internal clearances, vibration levels and increased operation safety
are combined, when symbol C is omitted from the second and following special bearing characteristics, e.g.:
P6 + C3 = P63
e.g. 6211 P63
P6 + C8 = P68
e.g. 16002 P68
C3 + C6 = C36
e.g. 6303-2RS C36
P5 + C3 + C9 = P539
e.g. 6205MA P539
P6 + C2NA + C6 = P626NA
e.g. NU1038 P626NA
Bearing Arrangement in Matched Set (16)
Designation of the arrangement in matched sets of two, three or four bearings consists of
symbols indicating the bearing arrangement and symbols determining internal clearance, or
preload of matched bearings.

Besides symbols shown in the table also U symbol is used and it indicates that respective
bearings can be universally matched, e. g. B7003CTA P4UL.
Internal Clearance or Preload
Introduced symbols are always used in combination with matching symbols.
A
bearing matching with clearance, e.g. 7305OA
O
bearing matching without clearance, e.g. 7305 P6XO
L
bearing matching with light preload, e.g. B7205CATB P4UL
M
bearing matching with medium preload, e.g. B7204CATB P5XM
S
bearing matching with great preload, e.g. B7304AATB P4OS

JU
reduced friction moment, e.g. 619/2 JU
JUA bearings with determined friction moment for starting up, e.g. 623 JUA
JUB bearings with determined friction moment for running out, e.g. 623 JUB
Grease (19)
For designation of bearings with shields or seals on both sides, filled with grease different from the standard
one, symbol combinations are used for designation. The first two symbols determine the operating temperature
range and the third (a letter) the name or type of lubricant, according to producer’s prescription, or another
symbol (a digit) determines the grease volume, which the sealed or shielded inner bearing’s space is filled with.
TL
grease for low operating temperatures from -60°C to +100°C,
designation example 6302-2RS TL
TM grease for medium operating temperatures from -35°C to +140°C,
designation example 6204-2ZR TM
TH grease for high operating temperatures from -30°C to +200°C,
designation example 6202-2Z TH
TW grease for both low and high operating temperatures from -40°C to +150°C,
designation example 6310-2Z C4TW
Note: Symbol TM need not be marked on bearings and packages.
Bearings acccording to Special Technical Terms
TPF
bearings produced according to special technical conditions agreed with the customer,
e.g. bearing 6205MA P66 according to special technical conditions TPF 11142-71 is designated: 6205MA P66 TPF142
TPF 99 double row spherical roller bearing for arrangements of railway vehicle axles, e.g.
23234 C3 TPF99
TPF204 single row ball bearings for fitting in kiln car wheels, etc., e.g. 6308 TPF204
TPFK
bearings according to special technical conditions agreed with the customer, which
have a great number of symbols indicating variations from the basic design.
In this case only the designation TPF..., is given, e.g. bearing NU1015, produced according to
technical conditions TPFK 11137-70 is designated NU1015 TPFK137.

2.3 Tolerance
Under bearing tolerance, dimension and operation accuracy is understood. Bearings are
manufactured in tolerance classes P0, P6, P5A, P4, P4A, P2, SP and UP.
Tolerance class P0 is the basic one and a decreasing number in designation means the higher
bearing tolerance class. Limiting values for dimension and operation acuracy shown in tables 20
to 30 comply with the standard ISO 492 and ISO 199 (STN 02 4612). Designation P5A and P4A
are used for bearings manufactured in corresponding tolerance class (P5, P4), or selected
parameters are in higher tolerance class than P5 and P4.

2.4 Internal Clearance
Bearing clearance is the value of one bearing displacement length of assembled bearing with
respect to the other ring from one end position to the other one. The displacement can be in radial
direction (radial clearance) or axial (axial clearance).
In a mounted bearing smaller radial clearance can be found than the same bearing had before
mounting. Radial clearance reduction is caused by interference of the bearing rings on the shaft and
in housing bore and thus it is dependent on selected tolerance of bearing seating surface diameters.
Another change of radial clearance, mainly its reduction, arises during operation from
temperatures evoked by its own operation and surrounding sources, but also by elastic
deformations caused by load.
Clearance for standard designed bearings is determined so that one of the bearing rings can be
fixed, what is sufficient for most operation conditions in the arrangement. For special
arrangements with different requirement on the radial clearance bearings with various radial
clearance designated C1 up to C5 are produced.
Values for various internal clearances according to the standard ISO 5753 are shown for
individual bearing types in tables 21 up to 27 and these values are valid for non-mounted bearings
by zero measuring load.
For double row angular contact ball bearings instead of radial clearance the axial clearance
measured at axial load 100 N is introduced.
Single row angular contact ball bearings and single row tapered roller bearings are usually
mounted in pairs and the radial or axial clearence is adjusted during mounting.

2.5 Cages
Cage in the rolling bearing fulfills the following roles :
- separates rolling elements evenly around the periphery
- prevents contact of rolling elements and their sliding
- prevents falling out of the rolling elements from separable or self-aligning bearings when
mounting.
From the point of view of design and material the cages are divided into pressed and machined.
Pressed cages are made of steel or brass sheet and are mostly used in dimensionally smaller and
medium bearings. Their advantage in comparison with the solid cages is the smaller weight.
Machined cages are made of steel, brass, bronze, light metals or plastic in various designs. Cages
made of metals are used when there are higher demands on the cage rigidity and the bearing is
determined for higher operational temperatures. Cages are radially centered on the rolling
elements in bearings, this is the most usual way, or they are centered on the rib of either of the
bearing rings.
Bearings without cages, i.e. with full complement of rolling elements, are only rarely used,
namely only for some bearing types, e.g. single row needle roller bearings.
In the texts about individual bearing types the survey of cages in standard design and delivery
possibilities of bearings with cages of non-standard design are given in the section Cages.
2.6 Shields and Seals
Bearings with sealing on one or both sides are manufactured with shields (Z, 2Z, ZR, 2ZR) or
seals (RS, 2RS, RSR, 2RSR).
Shields form a non-contact sealing. In design Z and 2Z the fitting for the shield is in the inner
ring, in design ZR and 2ZR the shield adheres on the smooth rib of the bearing inner ring.
Z
2Z
ZR
2ZR
Sealing is created by sealing rings made of rubber vulcanized on sheet steel reinforcement,
which create an effective contact sealing with a chamfered fitting on the inner ring (RS, 2RS) as
well as in design with contact on the smooth rib of the inner ring (RSR, 2RSR).
Seals and sealing rings are fastened in the grooves of the outer ring and are unseparable.
Sealing RS, 2RS, RSR, 2RSR can be used for temperature range -30°C to +110°C, sealing RS1,
-2RS1,RSR1 and -2RSR1 for temperature range -45°C to +120°C, sealing RS2, -2RS2, RSR2, -RSR2
for temperature range -60°C to +150°C.

Bearings with sealings on both sides in standard design are filled with grease of a temperature
range from -30°C to 110°C, whose qualities secure lubrication usually during the whole bearing life
at normal operational conditions. Bearings in this design cannot be relubricated.
3. Bearing Arrangement Design
3.1 General Principles of Rolling Bearing Arrangement Design
Rotating shaft or another component arranged in rolling bearings is guided by them in radial as
well as in axial direction so that the basic condition, the movement uniqueness, can be fulfilled.
The component should be, as far as possible, statically determined, i.e. supported in two points
radially and in one point axially.
A typical example of such an arrangement is in Pict. 9, where the shaft is radially guided in two
bearings, one of which secures it in axial direction. The locating bearing carries the radial load and
simultaneously also the axial load in both directions. Radial bearings that can accomodate
combined load are mostly used as locating bearings, which carry , e.g. single row ball bearings,
double row angular contact ball bearings, double row self aligning ball bearings, double row
spherical roller bearings or single row angular contact ball bearings and tapered roller bearings.
The two last mentioned bearing types must be mounted in pairs. The non-locating bearing carries
only radial load and must permit certain displacement of the shaft in axial direction so that arising
of non-desired axial preload caused by environment (temperature dillatations, production
inaccuracies of connecting arrangement components, etc.) can be hindered.
Axial displacement can be secured by displacement between one bearing ring and a machine
part, which is directly connected with the bearing, e.g. between outer bearing ring and housing
bore (Pict. 9a) or directly in the bearing (Pict. 9b).
Pict. 9
a
b
Arrangements, in which greater radial and axial loads act by higher rotational speed, should be
set up so that the bearing can accommodate only radial or axial forces, see Pict. 10. In these cases
it is possible to use for radial guidance some of the radial bearings and for axial guidance those
radial bearings which are also able to carry axial load or a pair of these bearings, or double
direction thrust bearing, or a pair of single direction thrust bearings. There is a condition where the
axially locating thrust bearing should be arranged with radial clearance.
Another, often used solution is the arrangement of two bearings, whose design enables the
accommodation both radial and axial loads. Both bearings accommodate alternately the axial
load, always according to direction of force acting, and simultaneously they carry also the radial
load. An example of this arrangement is shown in Pict. 11.
As a verified design the pair of single row tapered roller bearings or single row angular contact
ball bearings are used. There can be used other bearing types which are able to carry the load
both in radial and axial direction simultaneously, e.g. separable single row ball bearings or single
row cylindrical roller bearings in NJ design, etc.

3.2 Bearing Location
Radial and axial bearing location on the shaft and in the housing bore or another part has
a direct connection with the whole arrangement design. When selecting the way of location, the
character and acting forces magnitude, the operating temperature in the arrangement and
material of mating parts must be taken into account.
Mounting, dismounting and maintenance methods must be taken into consideration when
designing mating parts dimensions.
3.2.1 Radial Location of Bearing
The bearing is located in radial direction on the mating cylindrical shaft and housing bore
surface. In some cases, adapter or withdrawal sleeves are used by mounting on the shaft, or the
bearing can be mounted directly on the tapered shaft.
The correct radial location of the bearing on the shaft significantly influences utilization of its
load rating and correct function in arrangement. The following viewpoints are important :
a) safe location and uniform supporting of bearings
b) simple mounting and dismounting
c) displacement of non-locating bearing in axial direction
Basically, both bearing rings should be mounted in tight fits, because only in this way their
reliable supporting around the whole periphery and radial fixing against turning can be achieved.
To make mounting and dismounting easier or for moving the non-locating ring, a loose fit of one
of the rings is permissible.
When selecting correct radial bearing location, following influences must be taken into account.
Pict. 11
44
5:45 PM
S
Circumferential Load - occurs if the respective bearing ring rotates and the load direction is not
changed or if the ring rotates and the load does not rotate. The bearing ring periphery is gradually
loaded during one revolution. In this case the loaded bearing ring must be always fitted with
necessary interference fit.
Point Load - occurs when the bearing ring does not rotate and the external force is constantly
directed into the same ring raceway point or if the ring and load rotate at the same rotating speed.
The ring subjected to point load can be mounted with loose fit, if the conditions require it.
Indeterminate Load - occurs if the ring is subjected to varying external forces at which
directions and load changes cannot be determined (e.g. unbalanced mass, shocks, etc.). Under
these conditions in most applications bearings with greater radial clearance should be used.
Load Magnitude - directly influences selection of the interference fit (higher load - larger
interference), especially in cases of impact loads. A firm fitting on the shaft or in the housing
causes ring deformation, and as a result reduction of radial clearance arises. To secure the
necessary radial clearance in the firm arrangement, it is necessary to use bearings with greater
radial clerarance. Resulting clearance after mounting depends on the bearing type and its
dimension.
Bearing Size and Type - determines the size of necessary interference fit of the fitted ring. For
smaller sized bearings smaller interference fits are selected, and vice versa. Relatively smaller
interferences are used, e.g. for the same sizes of ball bearings in comparison with the cylindrical
roller, tapered roller or spherical roller bearings.
Material and Design of Mating Components must be taken into account when determining
their production tolerance. Results of practical experience are shown in the following tables. In
cases where bearings are mounted into housings made of light metal alloys or on journals of
hollow shafts, arrangements with higher interference are selected.
Split housings are not suitable for arrangements with higher interferences, because there is
danger of the bearing pinching in the dividing plane.
Heating generating in the bearing can cause loosening of the interference on the journal and
turning of the ring. In the housing a converse case can come into being. The heating causes
clearance decreasing and subsequently limiting and even stopping of the axial displacement of the
non-locating bearing ring. That is why we pay a great deal of attention to this fact when designing
an arrangement.
Fitting Accuracy from the point of view of its tolerances and geometric shapes is important
because it can be transmitted towards the bearing ring raceways and defines the arrangement
accuracy.
When using bearings with normal tolerance class, the tolerance of journal seating surface IT6 is
selected, and for housing seating surface tolerance IT7.
For smaller dimensioned ball and cylindrical roller bearings it is possible to use for the journal
tolerance IT5 and housing bore IT6.
For bearings in higher tolerance classes, for arrangements with high requirements on accuracy,
e.g. spindels of machine tools, the least tolerance class IT5 is recommended for the shaft and for
housing IT6.
Permissible ovality and conicity deviation and permissible lateral bearing runout of supporting
surfaces must be in reference to axis smaller than the diameter tolerance of the journal and bore.
With higher bearing tolerance class also requirements on the seating surface accuracy increase.
Recommended values are shown in tables 28 and 29.
Mounting and Dismounting of bearings, if one of the rings is arranged with a loose fit it is
simple. If, because of operational reasons, it is necessary to arrange both of the rings with an
interference, a suitable bearing type should be selected, e.g. a separable bearing (tapered roller,
45

S

cylindrical roller, needle roller bearing) or a bearing with tapered bore. Journals for sleeve
arrangements of bearings with tapered bore can be in tolerance class h9 or h10, geometric shape
should be in tolerance class IT5 or IT7 according to arrangement requirements.
Axial Displacement of Non-Locating Bearing Rings must be secured by all operation
conditions. When using a non-separable bearing, displacement of the stationary loaded ring is
reached by its fitting with clearance (moveable).
In light metal alloy housings it is necessary, if the outer ring is fitted with clearance, to put a steel
bush in the bore.
A reliable displacibility in axial direction is reached by using cylindrical roller bearing type N and
NU or radial needle bearing.
Recommended journal and bore diameter tolerances of the mating components for radial and
thrust bearings are shown in tables 30 to 35.
3.2.2 Axial Securing of Bearing
Inner bearing ring with cylindrical bore arranged on the journal with interference fit (fixed) is
usually secured in the axial direction by means of a locknut, end-plate or snap ring, when the other
face is usually supported by the shaft shoulder. Surrounding parts are used as abutment faces for
inner rings, and if necessary, spacing rings are inserted between this component and bearing inner
ring. Examples of axial bearing securing are shown in Pict.12.

Examples of axial locating of bearings with tapered bore seated directly on the tapered journal
or by means of an adapter or withdrawal sleeve are in Pict. 13.
Pict. 13
Permissible bearing axial load fixed by an adapter sleeve on smooth shafts without bearing
resting on the shaft shoulder is calculated according to equation :
Fa = 3Bd
Fa - permissible bearing axial load
B - bearing width
d - bearing bore diameter
[N]
[N]
[mm]
[mm]
If the axial displacement of the outer ring in the housing is not required, then we can use
solution, when the face supporting or seating surface of the bearing cover, nut or snap ring are
used. Bearings with grooves for snap ring (NR) do not require much space and their securing is
simple. Examples - see Pict. 14.
Pict. 14
Abutment dimensions for each bearing shown in this publication are in the dimension tables.
3.3 Sealing
Sealing of the bearing space is very important, because damaging materials which can be found
in the bearing environment influence it and often can cause its breakdown. Sealing also has an
opposite function - it prevents the lubricant leaking out of the bearing and arrangement space.
That is why sealing must always be designed with regard to operating conditions of machines or
equipments, arrangement design, lubricating method, maintenance possibility and economic
questions concerning production and utilization.
3.3.1 Non-Contact Sealing
Between non-rotating and rotating parts there is only a narrow gap when using this sealing. It is
filled with grease. Using this sealing, wear of components from friction does not occur and that is
why this sealing can be used for the highest rotational speeds and for high operating temperatures.
Examples of a gap sealing are in Pict. 15.

Another very effective sealing is the labyrinth sealing which can improve the sealing effect by a
greater number of labyrinths or prolongation of sealing gaps. Examples - see Pict. 16.
Pict. 16
3.3.2 Rubbing Sealing
Rubbing sealing is created of elastic or soft, but sufficiently impermiable material, which is
inserted between the rotating and firm part. Such a sealing is usually cheap and is suitable for
various designs. The disadvantage is the sliding friction of the contacting surfaces, and there fore
there is limited utilization for high rotational speeds.
Sealing with a felt ring is the simplest (Pict. 17). It is suitable for operating temperature -40° to
+160°C and for peripheral speeds to 7 m.s-1 and sliding surface roughness max. Ra = 0,16,
hardness min. 45 HRC or hard chromium plating. Dimensions of the felt rings are given by
corresponding national standards.
A very wide-spread way of sealing is sealing with shaft washers (Pict. 18). Radial shaft seal
washers are made of rubber or other suitable plastic reinforced by steel sheet reinforcement.
According to the material used they are suitable for operating temperature from -30° to +160°C.
Permissible peripheral speed depends on sliding surface roughness :
- to 2 m.s-1 is roughness max. Ra = 0.8

Except for mentioned most commonly used sealing rings there are rubbing sealing designs
which use the just formed sealing rings made of rubber, plastic, etc., or special spring rings. This
sealing is chosen either for applications with high requirements on bearing space sealing (great
environment pollution, high temperature, chemical substance influence), or for economic reasons
by mass or series production. Examples - see Pict. 19.
Pict. 18
Pict. 19
3.3.3 Combined Sealing
Increase sealing effect can be reached by non-contact and rubbing sealing combination. Such
a sealing is recommended for wet and polluted environment. Example - see Pict. 20.

4. Bearing Lubrication
The correct bearing lubrication has a direct influence on the bearing life. Lubricant creates
between the rolling element and bearing ring a carrying lubricating film which hinders their metal
contact. It lubricates surfaces where friction arises, it has cooling effect, it protects the bearing
from corrosion and in many cases seals the bearing space.
In the most cases - approximately 90%, bearings are lubricated with grease or oil, in rare
exceptions by other lubricating means. When deciding which lubricant and which lubrication
type should be used, operating conditions, characteristic qualities of the lubricant, equipment
design and operating economy should be taken into account.
4.1 Grease Lubrication
In the design practice grease lubrication is preferred to oil lubrication from the point of view of
arrangement simplicity, utilization of the sealing capabilities and simple maintenance.
For reliable bearing operation 1/3 to 1/2 of its free space is filled with grease at the first
assembly. A greater grease amount has negative influence on the operation. Higher passive
resistances cause the inner bearing space warming up undesirabely, which can lead to its
breakdown. Bearings making only a small number of revolutions during operation, from the point
of view of corrosion protection should be completely filled.
4.1.1 Relubrication Interval
Relubrication interval is the period during which the grease has the necessary lubricating
properties. After this period bearing must be relubricated, and old lubricant must be removed
from the bearing space completely.
Relubricating period depends on the bearing type and size, rotational speed, operating
temperature and grease quality. The recommended relubrication period for individual bearing
types at normal load (P 0.15 C) and normal operational conditions is shown in diagrams in Pict.
21 and 22. The diagrams are valid for common greases and temperatures to +70°C. For
temperatures over +70°C, the relubrication period is shortened for each 15°C on the half of
original value. For temperatures under +40°C the relubrication period can be doubled.
For small sized, especially single row ball bearings, the relubrication periods are several times
longer than the bearing life, that is why the bearings are, as a rule, not relubricated.
For this reason it is advantageous to use these bearings shielded or sealed on both sides and
filled with grease. For some rotational speeds the relubrication period is out of the diagram curve,
i.e. the permissible limit for grease lubrication has been reached and oil lubrication should be
used.
Necessary grease quantity for relubrication is calculated from the equation :
Q = 0.005 DB
Q - grease quantity
D - bearing outer diameter
B - bearing width
[g]
[g]
[mm]
[mm]
For bearings with higher rotational speed requiring a more frequent relubrication, it is necessary
to remove the used lubrication from the bearing space so that temperature increase should not
occur. For this reason the grease escape valve is suitable.
4.1.2 Bearing Greases
Bearing greases are produced most often of quality mineral or synthetic oils (sometimes with
additives), thickened with fatty acid metallic soaps. Greases must have good lubricating properties
and high chemical, temperature and mechanical stability. The grease list of bearing lubricants is in
Table 36.

4.2 Oil Lubrication
Oil lubrication is used, when operating rotational speed is so high that the grease relubrication
period is too short. Another reason can also be the necessity of heat transfer from the bearing, or
the high temperature of environment, which does not enable utilization of grease, or if
surrounding parts are already lubricated by oil (e.g. geared wheels in the gear box). Except for
some cases, spherical roller thrust bearings are always lubricated by oil.
When oil lubricating, lubricating must be secured both at starting and during operation. Excess
oil increases temperature and bearing temperature.
Oil feed into bearing is secured in various design ways, out of which oil bath lubrication with oil
level reaching middle of the lowest rolling element, oil circulation lubrication, jet lubrication, oil
mist lubrication etc., are the most common.
4.2.1 Bearing Oils
For bearing lubrication mostly refined oils with good chemical stability which can be improved
by antioxidizing agents are used.
The decisive oil property is kinematic viscosity which decreases with increasing temperature.
Suitable oil viscosity ν1 can be stated according to the diagram in Pict. 23 in dependence on the
bearing mean diameter ds = (d+D)/2 and rotational speed n. If the operating temperature is known
or it can be found out, according to the diagram in Pict. 24 suitable oil and viscosity ν at
internationally standardized temperature 40°C being necessary for calculation of ratio is
determined.
By ratio 1 it is recommended to use EP oil with additives which improve the oil film load
rating. By value decrease under 0.4 oils with EP additives are always used.
If the ratio is greater than 1, improved arrangement reliability is reached in operation.
Example :
- bearing d = 180 mm, D = 320 mm, ds = 250 mm
- rotational speed n =500 min-1
- presumed operating temperature 60°C
For these conditions according to diagram in Pict. 23 the minimum kinematic viscosity is
υ1= 17 mm2.s-1.
57
3/26/09
5:45 PM
S
3/26/09
If the operating temperature is 60°C, the oil selected according to the diagram in Pict. 24 at
standardized temperature 40°C must have kinematic viscosity υ min. 35 mm2.s-1.
For thrust spherical roller bearings the lubricating oil kinematic viscosity is approximately stated
in dependence on n x d, where n is the bearing rotational speed in revolutions per minute and d
is the bore diameter in mm, according to table 37. Lower values are valid for bearings with lower
load, for which is valid Pa 0.1 Ca . Higher values are valid for Pa 0.1 Ca.

4.3 Lubrication with Solid Lubricants
Solid lubricants are used for bearing lubrication when the grease or oil cannot fulfil the
requirements for reliable lubrication in conditions of limiting friction or from the viewpoint of high
operating temperatures, chemical influences, etc.
5. Mounting and Dismounting of Rolling Bearings
A very important requirement besides using the suitable mounting or dismounting tool is to
make sure these tools are clean and the whole operation can be carried out in clean working
environment. If this is not fulfilled, the impuritues have decisive influence on the bearing behaviour
in operation and can also cause bearing breakdown. In the same way the cleanliness conditions
must be fulfilled by the preparation of all lubricating means and components connected with the
arrangement.
New bearings are preserved by manufacturer with preservatives which need not be removed
before mounting. Bearings should be taken out just before mounting. Rarely the preservative is
removed from the bearing. For this operation are used:
- gas with 5 to 10% oil additive
- benzol
- diesel fuel
- water-free oil
After washing the bearing should be oiled, preserved from pollution and mounted as soon as
possible.
Before mounting, the seating surfaces dimensions should be checked for cleanliness or damage.
Mounting of Bearings with Cylindrical Bore
Bearings with cylindrical bore are mounted on the shaft at room temperature or heated.
Dimensionally smaller bearings are mostly mounted at room temperature.
The force necessary for mounting is reached by hammer blows or more suitably by press. In
both cases mounting jig is used. At mounting it is not permissible to transfer the mounting force
through rolling elements. That is why the jig must always be placed on the ring or both rings being
mounted while the mounting force is acting.
Heat mounting is used for greater bearings whose rings are fitted with a greater interference.
Maximum heating temperature of the bearing is 100°C.
Mounting of Bearings with Tapered Bore
Bearings with a tapered bore are mounted on the shaft by means of adapter or withdrawal
sleeves or are seated directly on the tapered journal. Reliable mounting is reached either by
pressing the inner ring by a nut, or by sufficient inserting of the sleeve. In both cases the inner ring
expands and bearing radial clearance decreases.
When mounting double row self aligning ball bearings the adapter sleeve nut can be tightened,
but only to such an extent that the outer ring can be easily turned and swivelled.
A double row spherical roller bearing is mounted with a greater interference. Mounting
reliability is checked according to radial clearance reduction by means of feeler gauges or
measuring the axial displacement of the inner ring on the journal or tapered sleeve. Initial position
for measuring this displacement is reached, when the contact surfaces (of the ring, sleeve, shaft)
seat on each other on the whole seating surface. Values for mounting double row spherical roller
bearings with tapered bore are shown in table 38.

Groove Ball
Bearings
Single row deep groove ball bearings are the most common bearing type and are designed as
non-separable and are without a filling slot. Good conformity to raceways is achieved by optimum
size and number of balls and relatively high load ratings are achieved. They accommodate both
radial and axial loads in both directions and are suitable for high rotational speeds.
Outer ring design of separable single row ball bearings - type E and BO enables separate
mounting of inner ring with cage and rolling elements. The bearings are produced from bore
diameter d = 20 mm and are suitable for smaller loads and high-rotational applications.
Boundary Dimensions
Boundary dimensions except for separable single row ball bearings - type E and BO correspond
to the standard ISO 15.
Snap ring groove dimensions comply with the standard ISO 464.
Designation
Bearing designation in standard design and common modifications (Z, RS, 2Z, 2RS, N) are
shown in the dimension tables. Deviation from standard design is designated by prefixes and
suffixes (section 2.2).
Shielded or Sealed Bearings
Single row deep groove ball bearings with shields or seals on one or both sides are produced
with metal shields (Z, 2Z, ZR, 2ZR) or seals (RS, 2RS, RSR, 2RSR) as non-separable units.
The shields create a non-contact sealing. Sealing rings are made of rubber, vulcanized on
a metal reinforcing ring and act in the bearing as an effective friction type sealing.
Z
2Z

Bearings with sealings on both sides are filled with grease which assures reliable lubricating
conditions for the whole bearing life. These bearings are suitable for temperature ranges

3/26/09 1:12:04 PM
of -30°C to +110°C. Delivery of bearings with another grease must be agreed with the
supplier in advance.

Bearings with Snap Ring Groove
For simple securing against axial displacement in the housing single row ball bearings with snap
groove on outer ring are manufactured (N). When the bearing is delivered with inserted snap
ring, it is designated (NR). Bearings with a snap ring groove can also be delivered with assembled
seals.

1) Bearing 618/8 is made with a solid cage made of polyamide (TNH)
For special arrangements bearings with different cages made of various materials are produced:
polyamide (TNH, TNB) and textite (TB). Using of these bearings should be discussed in advance.
Tolerance
Single row ball bearings are produced in normal tolerance class P0, this symbol is not indicated.
Limiting values for dimension and operation accuracy comply with the standard ISO 199 and ISO
492. Exceptions are only separable single row ball bearings - type E and BO, outer diameter of
which has limiting deviation D +0.01/0.00 mm.
65
3/26/09 1:12:04 PM
Radial Clearance
Single row ball bearings delivered without radial clearance designation are produced with
normal radial clearance. Radial clearance values comply with the standard ISO 5753.
Vibration Level
Commonly manufactured single row ball bearings have a normal vibration level checked by the
manufacturer. Bearings in tolerance class P5 and higher have the vibration level C6. For special
arrangements bearings with reduced vibration level C6, C06 and C66 are produced.
Tapered Bore
For some less demanding arrangements some sizes of single row ball bearings - type 62 and
63 with tapered bore, taper 1:12 can be produced. Fixing of bearings on the cylindrical journal is
made by means of adapter sleeves or directly on the tapered journal.
Bearings for Arrangements at High Operating Temperatures
For arrangements working at operating temperature to 400°C single row bearings with
adequately great radial clearance according to technical conditions between producer and
customer are delivered.
These bearings have reduced basic dynamic load rating in average of 50% and basic static load
rating of 30% in comparison with bearings in standard design.
Misalignment
For single row ball bearings only small mutual misalignment of bearing rings is permissible,
therefore alignment deviation of seating surfaces can be very small. Misalignment causes
additional loading of the bearing and thus its life is shortened.
Values of permissible misalignment at normal operating conditions are shown in the table.

Factor X and Y values are valid, if the bearings on the journal and in the housing will be fitted
in tolerances recommended for small and medium loads (tables 28 and 29) and during operation
significant reduction of radial clearance due to operating temperature does not come into being
(temperature gradient between inner and outer ring max. 10°C).

Single Row
Angular
Contact Ball
Bearings
Raceways of single row angular contact ball bearings are designed in such a way that the
connecting line of their contact points with the balls creates with the perpendicular line to the
bearing axis an acute angle, so called contact angle and are non-separable.Bearings in B and
BE design have contact angle α = 40°. This design allows the bearings to accommodate radial
loads, acting simultaneously with a relative great axial load in one direction. For axial load
accommodation in both directions, the bearings are arranged in pairs against each other.
In the production programme there are bearings in AA design where the contact angle is
α =26°, in A design the contact angle is α = 25°.

design, contact angle size, cage design and high tolerance class. Bearings are non-separable.
Bearings with CB designation have contact angle α = 10°. They are usually produced in
tolerance class P4, P4A and are determined for very precision arrangements with high rotational
speed, e.g. grinding electric spindles and appliances.
Bearings with designation CA have contact angle α = 12°.
Bearings in C design have contact angle α = 15°, they are produced in tolerance classes P5,
P5A and P4, P4A and are predominately used for machine tool spindle arrangements and similar
devices.
Bearings in AA design are produced in tolerance classes P5 and P4 and are determined for
machine tool spindle arrangement and similar devices with relatively higher axial load.
Boundary Dimensions
Boundary dimensions comply with the standard ISO 15 and are shown in the dimension tables
of this publication.
Designation
Bearing designation in standard design is a part of the data in the dimension tables. Difference
from standard design is designated by additional symbols (section 2.2).
Cage
Bearings - type 72 and 73 in B and AA design have a sheet cage which is not indicated. Bearings
- type 72 and 73 in BE design have a solid cage made of polyamide strengthened by glass fibres
(TNG).
Bearings - type A70 and A72 determined for high rotational speeds have a solid cage made
of textite, centered on outer ring (TA) and bearings - type B70 and B72 have a solid textite cage
centered on inner ring (TB), besides the bearing B7014AA which has a solid brass cage centered
on inner ring (MB).
Tolerance
Single row angular contact ball bearings - Type 72 and 73 are commonly produced in normal
tolerance class P0 which is not indicated. For more demanding arrangements bearings in tolerance
class P6 are delivered.
Bearings - type A70, A72, B70 and B72 in CA, C and A design are produced and delivered in
tolerance classes P5, P5A and P4, P4A.
Bearings - type A72 and B72 in CB design are produced only in tolerance class P4, P4A. Deliveries
of bearings in higher tolerance classes should be discussed with the supplier in advance.
Limiting deviation values of dimension and running accuracy comply with the standards ISO
199 and ISO 492 and are shown in tables 10 to 13.
Internal Clearance
Usual utilization of single row ball bearings is in pairs. Suitable operating clearance or preload is
adjusted at mounting and depends on arrangement design and operating conditions.
Bearing Arrangement in Pairs
Bearings in A70, A72, B70 and B72 design are determined for high rotational speeds and are
delivered in pairs.
Pair in “O” Arrangement (back to back)
This pair is significant by its high rigidity against tilting and carries axial forces in both directions
always only by one bearing. It is used for accommodation of tilting moments.
Arrangement scheme - see section 2.2 .
Pair in “X” Arrangement (face to face)
From the point of view of carrying axial forces this pair has the same properties as pair “O”, but
it has smaller rigidity for accommodating the tilting moment.
Arrangement scheme - see section 2.2 .
87
3/26/09 1:33:18 PM
Pair in “T” Arrangement (tandem)
This pair is significant by its rigidity against tilting, but it is capable of carrying the axial load in
one direction only.
O
X
T
Arrangement scheme - see section 2.2.
The matched bearing pair is delivered in a common package to prevent interchange. Position
of the greatest runout is marked by a line on ring faces. Mutual ring position is designated by
converging lines in “V” shape on the outer cylindrical surface of the matched pair. Bearings are
mounted in the arrangemet so that the lines indicating the place of the greatest runout can lie on
a line parallel to the shaft axis.
Matched pairs “X” and “O” are delivered with small (L), medium (M) and heavy (S) preload.
Designation example of such a pair - B7204CBTB P4OL or A7201AATA P5XM.
Axial preload is determined from relation :
Fp = k Cr . 10- 2
[kN]
Fp - axial preload
Cr - radial basic dynamic load
k - axial preload factor according to the table

Bearings Matching in Sets of Three and Four Bearings
For special accurate arrangement requiring high accuracy, rigidity, load rating and high
rotational speed bearings - type A70, A72, B70 and B72 matched in sets of three or four bearings
are delivered. Scheme of this arrangement - see section 2.2 .
Universal Bearing Matching
Single row angular contact ball bearings B70. .CTA in universal design (U) are determined for
matching in pairs, in “X”, “O” or “T” arrangements, or for matching in sets of three or four bearings.
They are manufactured with a light preload (UL) by “X” and “O” matching.
Bearing deliveries in universal design should be discussed with the supplier in advance.
Misalignment
Single row angular contact ball bearings mounted in pairs are sensitive to mutual bearing ring
misalignment.

If the shaft is arranged in two single row angular contact ball bearings, the acting radial load is
resolved into radial and axial components. The axial load of one bearing depends on the load and
contact angle magnitude of the other bearing. These additional inner forces must be taken into
account when calculating the bearing.
The following table shows relations for various bearing arrangements, when outer axial force
Ka, radial force FrA, or FrB act. Radial forces act in the intersection point of the contact line with the
shaft axis (dimension “a” in the dimension tables). Force magnitude is considered only in absolute
values in calculations. Calculated force Fa is given into the calculation of radial equivalent dynamic
load Pr .

Double Row
Angular
Contact Ball
Bearings
Double row angular contact ball bearings principally correspond to a matched pair of single
row angular contact ball bearings in an “O” arrangement. At the same size (d and D) the matched
pair has a smaller width.
The bearing has a filling slot on one side. If axial forces, which act in one direction, prevail, the
bearing should be mounted so that the forces should not act against the filling slot. They can also
be supplied equipped with plastic cage PA6 or PA66, designation TNG.
Bearing design enables the contact angle α = 32°. That is why they can carry tilting moments in
the axial plane. If there is lack of space only one bearing is sufficient for arranging a rotating part.
Boundary Dimensions
Designation
Bearing designation in standard design is a part of data in the dimension tables. The difference
from standard design is designated by additional symbols (section 2.2).
Cage
Double row angular contact ball bearings have cages pressed of steel sheet. They are not indicated. This is not valid for bearings with plastic cage (TNG) because they are not equipped with
filling slot.
Tolerance
Bearings are commonly produced in normal tolerance class P0, it is not indicated. For more
demanding arrangements bearings in higher tolerance class P6 are produced.
Limiting values of dimension and running accuracy are in tables 10 and 11 and comply with
standards ISO 199 and ISO 492.
Axial Clearance
Bearings are commonly produced with normal axial clearance, it is not indicated. For special
arrangements bearings with smaller C2 and greater C3 and C4 axial clearance are delivered.

Misalignment
Bearings form a very rigid arrangement especially sensitive to rings misalignment caused by
mounting inaccuracies.

Double Row
Self-Aligning
Ball Bearings
These bearings are designed with two rows of balls and a spherical raceway in the outer ring.
This allows certain misalignment of the inner ring against outer ring around bearing centre without
the bearing function being threatened. Bearings are produced with cylindrical and tapered bore
and are non-separable. Misalignment ability by not changed functionality determine this bearings
to utilize where some bore misalignment in housings or deflection and shaft oscillation are
presumed. With respect to a small contact angle and imperfect conformity of balls to raceways
they are not suitable for accommodating larger axial forces.
Boundary Dimensions
Designation
Bearing designation in standard design and in design with tapered bore is in the dimension
tables.
Difference from standard design is designated by additional symbols (section 2.2).
Tapered Bore
Bearings with tapered bore have taper 1:12. Bearings are fixed on cylindrical shafts by means
of adapter sleeves. Adapter sleeves designation corresponding to individual bearings is in the
dimension tables of this publication.
Cage
Bearings have the standard design cages according to the following table (material symbol and
cage design are mostly not indicated).

Single Row
Cylindrical
Roller
Bearings
These bearings are separable and are produced in several designs.
Design NU has cylindrical rollers guided between guiding ribs of the outer ring, the design N
between guiding ribs of the inner ring. Both designs enable mutual bearing rings displacement in
both directions.
E
ETNG
M
Design NJ has two guiding ribs on the outer ring and one on the inner ring, which enables to
carry the axial forces in one direction.
NUP design has a loose inner rib creating the second guiding rib of the inner ring and this enables
the bearing to carry limited axial forces in both directions. Axial guiding in both directions can be
achieved by means of angle rings HJ for bearings in NJ design and in one direction in NU design.
Single row cylindrical roller bearings have in comparison with single row ball bearings of the
same size higher basic load rating and are suitable for arrangements with high radial load, high
rotational speed and when light fitting of both rings is desirable.
Basic dynamic load rating of bearings with internal design E is in average higher by 30% as that
one for bearings with basic internal design.
Boundary Dimensions
Designation
Bearing designation in standard design is in the dimension tables of this publication.
Cages
Bearings in standard design have cage according to dimension tables. Material symbol and
symbol of the cage design are not indicated by bearings with pressed steel cage. For special
arrangements bearings with plastic or brass cages which can be coated with silver are produced.
This delivery should be discussed in advance.

Limiting deviation values of dimension and running accuracy are shown in tables 10 and 11 and
comply with standards ISO 199 and ISO 492.
Radial Clearance
Commonly produced bearings have normal radial clearance which is not indicated. For special
arrangements bearings with smaller clearance C2 or greater radial clearance C3, C4 and C5 are
delivered. Radial clearance values comply with the standard ISO 5753 and are shown in table
24.
Vibration Level
Commonly produced single row cylindrical roller bearings have normal vibration level checked
by the producer. Bearings in tolerance class P5 and P4 have vibration level C6. For special
arrangements bearings with reduced vibration level C6 are manufactured.
Bearings with Angle Rings
Angle rings - type HJ10, HJ2, HJ2E, HJ3, HJ3E and HJ4 can be used for bearings in NJ and NU
designs.
Examples of bearing designation :
NJ10 + HJ10 = NH10 NU10 + HJ10 = NUJ10
NJ2 + HJ2 = NH2
NU2 + HJ2 = NUJ2
NJ3 + HJ3 = NH3
NU3 + HJ3 = NUJ3
NJ4 + HJ4 = NH4
NU4 + HJ4 = NUJ4

Bearings without Inner Ring
For arrangements with limited space for bearing mounting, single row cylindrical roller bearings
without inner ring designated R NU are delivered. The inner bearing ring raceway is created
directly by the hardened and ground journal.
R NU
Dimension tolerance on the journal is usually “g6” for normal radial clearance, “f6” for greater
radial clearance and “h5” for smaller radial clearance. Ovality and cylindricity deviations of the
“raceway” on this journal must not be greater than deviations for tolerance class IT3. Surface
roughness for this surface should be Ra = 0.2 and for less demanding arrangements Ra = 0.4.
Basic load rating Cr and Cor values shown in the dimension tables, are valid for bearings R NU
if the journal surface hardness will be in the range 59 to 65 HRC. With decreasing hardness value
also load rating values Cr decrease. It must be multiplied by the factor fh from following table.
Minimum depth of journal hardening after grinding depends on the cylindrical roller diameter and
load magnitude and should be 1 to 3 mm.

Axial Dynamic Load Rating
Bearings with ribs on both rings can carry, besides the radial load, also a limited axial load.
Because permissible bearing load in axial direction depends on many factors, which cannot
be expressed only by a simple calculation, the following relations have only an informative
character.
The axial load in this case is not limited by the material fatigue but by the carrying capacity
of the lubrication film on the contact surface between the cylindrical roller face and guiding rib
and lubrication conditions and operating temperature and cooling possibilities of the bearing. At
common working conditions when the difference of the bearing and environment temperature
does not exceed 60°C, by slight heat transfer (0.5mWmm-2 °C -1), by viscosity relation 1.5 (section
4.2.1) it is possible to calculate maximum permissible axial load with sufficient accuracy from
equation :
Fa max 0.5 Cor × 104
n (d D)
0.05 Fr
[kN]
- for oil lubrication
Fa max 0.35 Cor × 104
n (d D)
0.03 Fr
[kN]
- for grease lubrication
Fa max - maximum permissible axial load
Cor - radial basic static load rating
Fr - radial bearing load
n - rotational speed
d - bearing bore diameter
D - bearing outside diameter
[kN]
[kN]
[kN]
[min-1]
[mm]
[mm]
Values Fa max calculated according to the above introduced equations are valid under assuming
of continuously acting axial force. For intermittent or impact load the permissible axial load can
be two- or three times greater in comparison with calculated value. For reliable bearing function
it is important that ratio Fa/Fr 0.4.

Double Row
Cylindrical
Roller
Bearings
Double row cylindrical roller bearings in NN design have two rows of cylindrical rollers guided
by three ribs on inner ring. The outer ring is without ribs, that is why these bearings cannot carry
axial forces. Double row cylindrical roller bearings - type NN30K are commonly produced with
tapered bore, taper 1:12 (K).These bearings can be also delivered with cylindrical bore (must be
agreed in advance). Double row cylindrical roller bearings are significant for their great rigidity
and are predominately used for spindle arrangements of machine tools and similar equipment.
Double row cylindrical roller bearings - type NNU49 have three guiding ribs on outer ring and
smooth inner ring. Bearings can carry only radial loads. Bearings - type NNU4920 and NNU4924
are also delivered matched in pairs according to the technical conditions TPF 11322-80. In this way
matched bearing pairs fulfil in the arrangement the role of four-row cylindrical roller bearings and
are suitable for arrangement of rolls in rolling mills, etc.
Boundary Dimensions
Designation
Difference from standard design is designated by additional symbols according to STN 02 4608
(section 2.2).
Lubrication Groove and Holes on Outer Ring
All sizes of double row cylindrical roller bearings with tapered bore - type NN30K can be
delivered with groove and lubrication holes on outer ring (W33). This bearing design allows the
introduction of the lubricant directly into the bearing between two cylindrical roller rows. In this
way better bearing lubrication and higher operating reliability are reached.
Cages
Cylindrical roller bearings are commonly produced with a machined brass cage which is usually
not designated. Bearings type NNU49 are produced with machined brass cage (M) which is
designated.
Tolerance
Cylindrical roller bearings with tapared bore are produced only in higher tolerance classes P5
and P4. Limiting values for dimension and operation accuracy for tolerance classes P5 and P4 are
in tables 12 and 13.
Bearings NNU49 and NN39 are produced in normal tolerance class. Bearing delivery in
tolerance class P6 should be agreed with the supplier in advance.

3/26/09 1:51:59 PM
Radial Clearance
Cylindrical roller bearings with a tapered bore are produced with reduced radial clearance
and with mutually non-interchangable rings C1NA and C2NA. Symbols C1NA and C2NA are
connected with tolerance class symbols P5 and P4, e.g. P5 + C1NA is designated P51NA. Values
of radial clearance are shown in table 25. Bearings - type NNU49 are produced with normal radial
clearance. Bearings delivery with radial clearance greater than C3 should be discussed with the
supplier.
Misalignment
Double row cylindrical roller bearings are not suitable for arrangements where alignment of
inner and outer bearing rings is not secured.

Single Row
Needle
Roller
Bearings
Single row needle roller bearings have needle rollers guided in axial direction by outer ring
ribs and the inner ring is smooth as well as by single row cylindrical roller bearings in NU design.
That is why these bearings cannot carry axial loads. Single row needle roller bearings have a small
height of the cross section and relatively high basic load rating and are especially suitable for
arrangements with limited space in radial direction. Bearings have a groove and lubrication holes
on the outer ring periphery. Single row needle roller bearings are produced without cage. Bearings
without cage (V) have a full complement of cylindrical rollers which results in higher load rating,
but smaller limiting rotational speed in comparison with bearings of the same size with cage.
Bearings are also delivered without inner ring (R NA). In this case the inner raceway is created
directly on the journal.
Boundary Dimensions
Designation
Tolerance
Single row needle roller bearings are commonly produced in normal tolerance class P0 (symbol
P0 is not indicated). For special arrangements demanding accuracy, bearings in higher tolerance
class P6 are delivered. Delivery of these bearings should be discussed in advance. Limiting values
of dimension and running accuracy are shown in table 10.
Radial Clearance
Commonly produced single row needle roller bearings have normal radial clearance which is
not indicated. For special arrangements bearings with greater radial clearance (C3) are delivered.
Radial clearance values are shown in table 26.
Bearings without Inner Rings
For arrangements with limited mounting space single row needle roller bearings without inner
ring are delivered (R NA). Needle rollers of these bearings roll directly on the ground journal. Inner
raceways diameter tolerances for single row needle roller bearings without inner ring are shown
in following table.

Raceway deviations of roundness and cylindricity must not be greater than deviations for tolerance class IT3. Values of basic load ratings Cr and Cor, shown in dimension tables are valid for
bearings without inner ring if inner raceway hardness on the journal will be in the range 59 to 65
HRC. With decreasing raceway hardness also the load rating values decrease and the table value
Cr should be multiplied by factor ft (Table 7). Minimum depth of hardened layer after grinding
should be 1 to 3 mm according to bearing dimension and load. Raceway surface roughness for
common arrangements Ra = 0.2, for less demanding arrangements Ra = 0.4.
Misalignment
Mutual ring misalignment of single row needle roller bearings is small. Permissible misalignement
values are to 2’.

Roller
Bearings
Double row spherical roller bearings have two rows of spherical rollers with a common
sphered raceway in the outer ring. This design enables mutual misalignment of rings. They can
simultaneously carry great radial and axial load in both directions. These bearings are produced
with both cylindrical and tapered bore. These bearings are suitable for arrangements where great
loads are acting and misalignment should be secured.

Boundary Dimensions
Designation
Bearing designation in standard design and in design with tapered bore is in the dimension
tables of this publication.
Tapered Bore
Bearings with tapered bore have taper 1:12, for type 240 the taper size is 1:30 (K30). Bearings
with tapered bore are fixed on the cylindrical shafts by means of adapter sleeves. Sleeve
designation corresponding to individual bearings is in the dimension tables of this publication.
Lubrication Groove and Holes on Outer Ring
All types and sizes of double row spherical roller bearings are delivered besides the standard
design also design W33 with groove and lubricating holes along the pheriphery that provides
better lubricating and higher reliability.
Cage
Bearings have cage material and design as shown in the dimension tables of this publication.
Bearings with symbols J and E have pressed steel cage, bearings with symbol M have machined
brass cage.
Tolerance
Double row spherical roller bearings are commonly produced in normal tolerance class P0
which is not indicated. Bearing delivery with higher tolerance class should be discussed with the
supplier in advance.
Radial Clearance
Commonly produced bearings have normal radial clearance which is not indicated. For special
arrangements bearings with smaller clearance C2 and greater radial clearance C3, C4 and C5 are
delivered. Radial clearance values comply with standard ISO 5753 and are shown in table 27.
Misalignment
Bearings can misalign from the central position without affecting their correct function. The
following table shows permissible misalignment values according to bearing type.

Single Row Tapered Roller Bearings
A design with a great number of tapered rollers in one row enables these bearings to reach high
load ratings both in radial and axial directions. Axial load can be applied only in one direction and
its size depends on the contact angle size. Bearings with a greater contact angle (type 313 and
323B) are suitable for greater axial forces.
Single row tapered roller bearing arrangement is usually created by a pair of bearings because
of bidirectional accommodation of axial load.
Bearings are produced in design with higher utilization parameters - designation A. Besides
bearings in metric dimensions bearings in inch dimensions are also produced.
Boundary Dimensions
Boundary dimensions of metric single row tapered roller bearings comply with the standard
ISO 355.
Boundary dimensions of single row tapered roller bearings in inch dimensions are according to
the standard AFBMA Standard 19 (USA) from 1974.
Designation
Bearing designation of standard bearings is in the dimension tables of this publication.
Difference from basic design is indicated by additional symbols shown in section 2.2 .
According to the dimensional plan ISO 355 the metric single row tapered roller bearing designation
consists of letter and numerical symbols expressing following :
T
bearing type
2, 3, 4, 5, 7
angle series of bearing
B, C, D, E, F, G diameter series of bearing
B, C, D, E
width series of bearing
000
bore diameter in mm
For customer’s and producer’s orientation previous the designation is retained in the dimension
tables and designation according to ISO is also shown.
The bearings designation in inch dimensions corresponds to usual way of designation of most
producers of these bearings. The number preceding the slash indicates the cone with tapered
rollers and cage, the number after the slash indicates the cup.
Cage
Single row tapered roller bearings have pressed steel cage which is not designated. Additional
symbol J2 indicates a new cage design.

Tolerance
Bearings are commonly produced in normal tolerance class P0 which is not indicated. For
arrangements demanding more accuracy or working with high rotational speed, bearings in
higher tolerance class P6, P6X and P5 are delivered. Delivery of bearings in P6X and P5 should be
discussed in advance.
Internal Clearance
Single row tapered roller bearings are mounted in pairs, in which required clearance, or preload
are adjusted at mounting. Clearance or preload size is determined according to arrangement’s
requirements.
Misalignment
Seating surface for single row tapered roller bearings must be aligned only with small deviations
because ring misalignment is very small. By common operating conditions the misalignment is
- at small load (Fr 0.1Cor) 1’ to 1.5’
- at great load (Fr 0.1Cor) 2’ to 4’

Values of factors e and Y for individual bearings are shown in the dimension tables of this
publication.
If the shaft is arranged in two single row tapered roller bearings additional inner axial force
rises. Load magnitude of one bearing depends on load and contact angle of the second bearing.
Additional inner forces must be taken into account by calculation. In the table relations for
various bearing arrangements at acting outer axial force Ka, radial FrA, FrB loading bearing A and B
are shown.
Radial forces act in the intersection of the contact line with bearing axis (dimensions „a”, „s” are
in the dimension tables) and in calculation are considered for positive even then, when they have
reverse direction than in the picture.
Calculated force Fa is introduced to the calculation of radial equivalent dynamic load.

Thrust Ball
Bearings
From the point of view of design, thrust ball bearings are divided into single direction and
double direction.
Single direction thrust ball bearings consist of two washers with raceways and balls guided by
a cage. Washers have flat seating surfaces, and that is why they must be supported so that all
balls can be evenly loaded. Bearings carry the axial load only in one direction.They are not able
to carry radial forces.
Double direction thrust ball bearings have two cages with balls between the central shaft
washer and two housing washers with flat seating surfaces. The shaft washer has raceways on both
sides and is fixed on the journal. Bearings are able to carry only axial forces in both directions.
Bearings up to the outer diameter D = 150 mm are produced in new design and have higher
utilization parameters.
Boundary Dimensions
Designation
Cage
Thrust ball bearings have in basic design cage a according to the table. Material and design
designations are not indicated.
Customer’s requiring special arrangements should be discuss this in advance with the supplier.

Tolerance
Bearings are commonly manufactured in tolerance class P0 which is not indicated. Bearings for
more demanding arrangements are delivered in tolerance classes P6 and P5.
Limiting values of dimension and running accuracy are shown in Table 20.
Misalignment
Bearings require keeping the tolerance for seating surfaces alignment, because misalignment
causes increased stress at the contact of the balls with raceways. Therefore where alignment
conditions cannot be kept, the use of thrust ball bearings is not recommended.
Axial Equivalent Dynamic Load
Pa = Fa
[kN]
Minimum Axial Load
At higher rotational speeds danger of ball sliding between ring raceways can occur because
of centrifugal forces, if axial load Fa drops under minimum value. Minimum value Fa is calculated
from equation:
n ax
Fa min M m
1000
冢
přičemž:
Fa min – minimum axial load
nmax – maximum rotational speed
M
– minimum axial load factor
(values are in dimension tables)
冣

[kN]
[kN]
[min-1]
If the axial load is smaller than Fa min , or if bearing relieving comes into being during operation,
e.g. of one ball row in double direction bearing, or of one bearing when using a pair of single
direction thrust bearings, it is necessary to secure minimum load, e.g. by means of springs.

Spherical
Roller Thrust
Bearing
Spherical roller thrust bearings have a great number of asymetrical spherical rollers with a good
conformity to the raceway of the shaft and housing washers and that is why they are suitable for
accommodating great axial load as well as certain radial load at relatively high rotational speed.
Bearings are separable which can be utilized when mounting.
The internal bearing design requires oil lubrication. An exception is created by conditions where
the bearing is working at very small rotational speed.
Bearings are produced in several designs, see picture. Delivery of bearings in “J” design should
be discussed with the supplier in advance.
J
EM
EJ
Boundary Dimensions
Boundary dimensions of spherical roller thrust bearings comply with the standard ISO 104 and
are shown in dimension tables.
Designation
Bearing designation of standard bearings is in the dimension tables of this publication.
Difference from basic design is indicated by additional symbols shown in section 2.2 .
Cage
Spherical roller thrust bearings in “M” design have brass cages guided by a steel sleeve on the
shaft washer.
Bearings in “J” design have pressed steel cages guided on the shaft washer.
Bearings in “J” design are interchangable with bearings with machined brass cage. If the bearing
with machined brass cage is to be replaced in arrangement, where the shaft washer rests on the
shaft on the face of steel sleeve which guides the cage by the bearing in “J” design, it is necessary
to insert a spacer between the shaft washer and original shaft shoulder, as shown in the picture.

3/26/09 3:09:19 PM
Tolerance
Bearings are commonly produced in normal tolerance class P0 which is not indicated.
Limiting values of dimension and running deviations are shown in table 20.
Misalignment
Spherical raceway of the bearing housing washer enables, at common operation conditions
(Pa 0.1Ca) misalignment from the central position without damaging the correct bearing function
of values according to the table below.

Arrangement Design
Abutment and fillet dimensions shown in the dimension tables of this publication are suitable
for bearings where the load Pa 0.1Ca. At higher load it is suitable to support bearing washers
along the face surface, i.e. da = d1 and Da = D1.
Axial Equivalent Dynamic Load
Pa = Fa + 1.2F
(Fr 0.55Fa)
[kN]
Minimum Axial Load
At higher rotational speed by spherical roller thrust bearings arises the danger of rolling element
sliding. A potential problem exist in the use of spherical roller thrust bearings at higher rotational
speed. the danger arises from the possibility of the rolling element sliding between raceways due
to centrifugal forces acting in such cases when the axial load Fa drops under minimum value. For
calculation of minimum value Fa min following relation is used:
冢

If the external axial bearing load is too small, or if the bearing is relieved in operation, e.g. in
a bearing pair, it is necessary to create axial load, e.g. with springs. If also radial load acts the
simultaneously, following condition must be fulfilled:
Fr 0.55Fa
Axial Equivalent Static Load
Poa = Fa + 2.7Fr
(Fr 0.55Fa)

Static safety factor for spherical roller thrust bearings must be so 4.

Insert Ball
Bearings
and Insert
Ball Bearing
Units
Insert ball bearings are single row deep groove ball bearings with double sealing on both sides.
The outer ring has a spherical surface and that is why it can tilt in the housing with the same
spherical surface. It can accommodate eventual misalignments. The inner bearing ring is wider
than the outer one and it is fixed on the shaft :
– by means of eccentric locking collar, design UA
– by means of screws, design UC
Bearings are filled with grease for the whole bearing life. Housing designs allow eventual
relubrication by means of a lubricating nipple.
Bearings are suitable for arrangements on short shafts and for arrangements where small thermal
contraction occur which are compensated by bearing axial clearance or design adaptability, on
which bearing housings are fixed.
The material of insert ball bearing housings are grey cast iron or steel sheet and from the point
of view of design the housings can be in pillow block - designation SG, SA or flanged - designation
FG, FM, FB, FE. In the housing there is a spherical hollow and they form together a unit which
enables an economic solution with a simple arrangement design.They are used in agricultural
machines, transportation equipments, food-making machines, etc.
Boundary Dimensions
Boundary dimensions of insert ball bearings correspond to the standard ISO 2264, ISO 3228
and bearing housings and eccentric locking collars to the standard ISO 3145.

Designation of insert ball bearings, corresponding housings and complete units is in the
dimension tables of this publication.
Cage
Bearings have cages pressed of steel which are not designated.
Tolerance
Bearings have a uniform bore diameter tolerance H6. This tolerance secures by shaft machining
in the tolerance h always a loose fit. For shaft manufacturing usually tolerances h8 and h11 are
sufficient. For greater loads and rotational speeds it is necessary to select tolerances h6, h7.
Radial Clearance
Commonly manufactured insert ball bearings have normal radial clearance which is not indicated
and its size and extent is the same as for single row deep groove ball bearings of the same
dimensions.

3/26/09 3:09:21 PM
Delivery of bearings with different radial clearance should be discussed with the supplier in
advance.
Limiting Rotational Speed
This parameter is dependent on the arrangement on the shaft and from the point of view of
shaft diameter the dependence in the dimension tables is worked out.

Spherical
Plain
Bearings
Spherical plain bearings are radial sliding bearings consisting of one inner and one outer ring
which have spherical functional surfaces. Bearings are determined for arrangements where great
radial forces at slow tilting or oscillating are acting and for arrangements where space adjustability
of both components is secured. Besides radial load, bearings can also accommodate an axial load
of certain magnitude in both directions.
Spherical plain bearings are produced of bearing steel. Rings are hardened, ground or
phosphatizated. Spherical plain bearings require minimum service. At first mounting the bearings
are filled with grease and are relubricated in certain time periods according to operating conditions.
For spherical plain bearings lubrication mainly greases with EP or MoS2 additives are suitable.
Boundary Dimensions
Boundary dimensions of spherical plain bearings - Type GE comply with the international
standard ISO 6124/1 (STN 02 3515) and bearings - type GEW with enlarged inner ring the
international standard ISO 6124/2 (STN 02 3516).
Designation
Spherical plain bearings designation in standard design is shown in the dimension table and
consists of type designation (GE or GEW) and size (digit indicates bore diameter in mm), e.g.
GE30. Deviations from standard design (radial clearance, sealing, dimension change) are indicated
by additional symbols according to STN 02 4608 (except for symbol E), placed after the basic
designation. Symbol E - phosphatizated bearing surface, e.g. GE30E.
Tolerance
Spherical plain bearings are produced in normal tolerance class which is not indicated. Deviation
values correspond to the international standard ISO 6125.

Withdrawal Sleeves
Withdrawal sleeves are used for fixing double row spherical roller bearings with tapered bore (K)
on cylindrical shafts. Withdrawal sleeve material is steel with tensile strength 400 to 600 MPa.
Boundary dimensions of withdrawal sleeves and corresponding withdrawal nuts, which must be
ordered separately, correspond to the standard ISO 2982.
Withdrawal sleeve and corresponding withadrawal nut designation to individual double
row spherical roller bearings with tapered bore is shown in dimension tables devoted to these
bearings.
Abutment and fillet dimensions for bearings with withdrawal sleeves (da min , Da max , ra max) are the
same as for bearings without withdrawal sleeves and are indicated in corresponding dimension
tables.
Locknuts and Withdrawal Nuts
Locknuts and withdrawal nuts are used for fixing inner bearing rings on adapter sleeves or
directly on the shaft. Withdrawal nuts serve for dismounting of double row spherical roller
bearings with tapered bore fixed by means of a withdrawal sleeve. Material for nuts is steel with
minimum tensile strength 410 MPa.
Boundary dimensions of locknuts and withdrawal nuts shown in the dimension tables
correspond to the standard ISO 2982.
Locknuts are produced in normal design (type KM) and in precision design (type KMA) and are
shown in the dimension tables of this publication. When determining the axial runout parameter,
following table is valid:

Locking Washers
Locking washers serve for locating of locknuts and are produced of steel with minimum tensile
strength 274 MPa. Locking washer boundary dimensions are in the dimension tables of this
publication and correspond to the standard ISO 2982.
Snap Rings for Bearings with Snap Ring Groove on Outer Ring
Snap rings are used for simple axial fixing of bearings with a groove on outer ring (N) in
housings. Material for snap rings is spring steel. Boundary dimensions for snap rings correspond
to the standard ISO 464.
Snap rings are designated by a number indicating the outer bearing diameter D and a number
indicating minimum snap ring width f, e.g. 52/1.02.
In practice also a commercial designation wich indicates the ring type R and outer bearing
diameter in mm, e.g. R52, is used.
In the dimension tables snap rings for single row ball bearings - type 60, 62, 63 and 64 in N
design are shown.
Snap rings can also be used also for bearings in different design, their delivery should be
discussed with supplier in advance. Snap rings are delivered separately.

Balls
Balls as a rolling bearing component are made of the same material as bearing rings. The material hardness after processing (hardening) is 61 to 65 HRC.
Balls with diameter Dw = 3.175 to 17.462 mm are supplied within the tolerance classes 10, 16,
20, 28, 40, and 100. Balls with diameter Dw = 18.256 to 33.338 mm are supplied within the tolerance classes 16, 20, 28, 40 and 100 according to the international standard ISO 3290.
The delivery of balls in different tolerance class or made of a different material should be discussed in advance.
Within each tolerance class, balls of the same nominal diameter Dw are graded into grades
according to mean grading deviation of the nominal ball diameter in the lot ΔDwm.
Each grade is packed separately and is marked in documentation and package by the value of
the nominal diameter mean deviation in the lot in μm, e.g.
Balls 6 - 40 + 4
This means that the ball has the nominal diameter 6 mm, tolerance class 40 and has the actual
diameter within 6.003 to 6.005 mm.

Cylindrical Rollers
Cylindricals rollers are produced with convex contour of the rolling surface or in design with
straight line contour and end crowned towards both faces (ZB).
After being made of rolling bearing steel the cylindrical rollers have hardness 60 to 65 HRC.
Cylindrical rollers are usually delivered in the tolerance class III (DIN 5402). Delivery of rollers
made of different dimensions or materials in than dimension tables of the catalogue should be
Within each tolerance class, the cylindrical rollers of the same nominal diameter Dw and nominal
length Lw are graded according to the mean grading deviation of the nominal cylindrical roller
diameter and length.
Example of cylindrical roller designation is shown in documentation and packing.
Short cylindrical roller 8 x 12 ZB III + 2/-3
this means that the cylindrical roller has nominal diameter 8 mm and nominal length 12mm in ZB
design, tolerance class III and has actual diameter 8.001 to 8.003 mm and actual length 11.994 to
12.000.

Special
Rolling
Bearings
In addition to standard and modified bearings shown in this catalogue, special rolling bearings
are also made. As a rule, they have non-standard dimensions and cannot be involded in the
standard types, they are made of different materials and are determined for usage in machines or
equipment arrangements whose design does not allow standard bearings.

Bearings correspond to the requirements of international standards ISO, EN and UIC.
Used for axle arrangements of passenger cars and wagons, motor coaches and locomotives.
Bearings have a solid brass cage centered on cylindrical rollers, or on the ribs of the outer
ring (in this case the cage has lubrication grooves). Inner rings and semi - units are mutually
interchangeable.

Bearing Units
Double Row Ball Bearings for Textile Machines and Instrument Technics
Bearings for textile machines are designed for high speed and relatively low load, i.e. they have
high dimension and operation accuracy, which secures their high utilization value and operating
reliability. Bearings create a nonseparable unit consisting of a shaft and a cylindrical bush arranged
in a rotary way on two rows of balls. Light one - side cages made of plastic are centered on rolling
elements. Raceways on the shaft and in the bush are made in the high tolerance class. Against
impurity penetration there are effective contact or non-contact sealing on both sides. Bearings are
filled with grease which secures effective lubrication usually during the whole bearing life. In some
cases the bearings are adapted for re-lubrication. The bearing creates a complex arrangement unit
enabling simple mounting and service. Bearings for instrument technics have also high dimension
and operation accuracy and work as a rule at lower speed than bearings in textile machines.
Double Row Bearings for Water Pumps of Combustion Motors
Bearings for water pumps of combustion motors create an inseparable unit consisting of a
shaft and a cylindrical bush arranged in two rows of balls or in one row of balls and one row of
cylindrical rollers. Balls or cylindrical rollers are arranged in light one-side plastic cages. Raceways
on the shaft and in the cylindrical bush are made in high tolerance class. Against impurity
penetration there is an effective contact sealing on both sides. Bearings are filled with grease
which secures effective lubrication during the whole bearing life. The bearing creates a complex
arrangement unit enabling simple mounting and service.
Bottom Bracket Bearings for Bicycles
Bottom bracket bearings for bicycles create an inseparable unit consisting of a steel case
-hardened or hardened shaft and a cylindrical bush made of bearing steel or of AL- alloy or also of
polyamide filled with glass fibre. Raceways for two rows of balls are created by grinding directly
on the shaft and in the cylindrical bush. Balls are arranged in one - side light cages made of plastic.
Against impurity penetration there is a rubber contact sealing on both sides. Bearings are filled
with grease which secures effective lubrication during the whole bearing life.
The advantage of these bearings is that they do not demand any maintenance and when
mouting no clearance adjustment is necessary as for classical arrangements, because the optimum
clearance is set directly by the bearing manufacturer.

For bearing clamping into the bicycle frame hub dishes made of galvanized steel or plastic are
used. Ring dish creates one unit with the double row ball bearing, left dish is indepedent and
supports the bearing only radially. By this design the bearing compact can be universally utilized
for bicycles with various frame hub length in the range 66 to 71 mm.
Survey of Further Special Rolling Bearings
Single Row Ball Bearings
For industrial needs, especialy for automobile, aircraft industries and industries dealing with
production of transportation equipment the bearings shown in the picture below have been
developed and are being manufactured.
Clutch Bearings
Used in automobile industry for clutches of passanger cars and trucks.
234
3/26/09 4:44:11 PM
Used in automobile and aircraft industries.
Multi-Row Cylindrical Roller Bearings
Used for accommodation of especially great radial forces with limited space, especially in
metallurgy, for arrangement of rolling mill rollers. These bearings have rings with lubricating holes
so that access of lubricant into all cylindrical roller rows can be secured.
Single Row and Double Row Tapered Roller Bearings
Used prevailingly in automobile industry and in the area of heavy mechanical engineering.
Double Row Tapered Roller Bearings
Used for arrangements of rolling mill rollers and other equipments in steel rolling mills.

Slewing Rings with Crossed Rollers
Slewing rings with crossed rollers in standard design are compact double - ring bearings with
cross arrangement of cylindrical rollers in the raceway between inner and outer ring. Cylindrical
rollers are in most cases split by separators made of plastic, or by a compact or segment cage.
Contact angle of the raceways is usually 45°. Bearings are delivered with clearance or preload, it
depends on their utilization. Bearing rings have holes for fixing screws. Inner space is protected
by seals against excessive grease leakage from bearing and penetration of macro - impurities into
the bearing.
They are produced with outer diameter from 300 to 2500 mm, with intenal or external gear,
or without gear for arrangements of construction and earth machines, robots and manipulators,
machine tools, cutter loaders, rotating shields, wind-power plants, and rotational furnaces.
Slewing Ring with Balls
Bearings are suitable for both durably rotating equipments and for machines with a cyclical character
of work having medium size e.g. excavators and cranes. For higher rotational speed bearings with
compact or segment cage are produced. They have relatively low friction moment. Arrangement
rigidity with the use of ball bearings is lower than by crossed roller bearings. Their contact angle is
usually 45°.
They are produced with outer diameter from 300 to 2650mm with internal or external gear, or
without gear.

Double Direction Cylindrical Roller and Tapered Roller Thrust Bearings
Used for accommodation of great axial forces in rolling mill roller arragements and also where
great rigidity in axial direction is required, mainly in arrangement of vertical lathe tables.
More precise information concerning special bearings can be obtained in firms' publications.
