DOUBLE ROW SPHERICAL ROLLER BEARINGS
Double row spherical roller bearings have two rows of spherical rollers with common spherical raceway in
outer ring. This internal bearing design enables mutual tilting of rings. Under load the spherical roller in some
designs rest by their facial surface on fixed or floating center rib, guiding the rollers. Double row spherical roller
bearings are not easily separable and are being mounted as a complete unit. They can accommodate great
radial and simultaneously also axial loads in both directions. Double row spherical roller bearings have either
cylindrical or tapered bore and are produced with steel sheet cage (J) or with machined brass cage (M).

All double row spherical roller bearings are designed and manufactured according to Czech CSN standards,
which fully comply with the international standards ISO. Quality management system of the whole manufacturing process of double row spherical roller bearings is certified according to international standards series
ISO 9000.
Double row spherical roller bearings are utilized in many industrial branches. For their specific properties they
are particularly suitable in the following installations and mechanisms:
– gearboxes of trucks and heavy-duty construction, road building and mining machinery
– heavy-duty paper machines
– mountings of railway car axles and bogies, electric locomotives
– intricate mountings of tunnelling machines and shields, screening and sorting machines
– heavy engineering industry: presses, intricate turntables, heavy-duty machine tools, crushers, cranes
– metallurgical industry: rolling mills, converter mountings
– power industry: turbines, generators.
Boundary Dimensions
Boundary dimensions of double row spherical roller bearings shown in dimensional tables comply with international dimensional plan ISO. Manufacture of bearings of differing dimensions should be negotiated with the
manufacturer first.
Review of Bearings Execution

Groove and Lubricating Holes on Outer Ring
When double row spherical roller bearings are provided with a groove on perimeter and with three lubricating
holes (W33), eventually three lubricating holes only (W20) , the lubricant can be fed straight into the bearing
between two spherical roller rows. This enables to achieve better lubrication and higher operating reliability.
Tolerance
Double row spherical roller bearings are commonly manufactured in normal tolerance class PO. This symbol
is not shown in bearing designation. Manufacture of bearings of higher tolerance class should be negotiated
with the manufacturer. Limiting deviation values of dimensions and run tolerances are shown in ISO 492.
Radial Clearance
Currently manufactured double row spherical roller bearings are of normal radial clearance, which is not
shown in bearing designation. On client’s request for special purpose arrangements these bearings may be
manufactured with radial clearance C2 (lesser than normal) or with radial clearance C3, C4 or C5 (greater
than normal). Clearances values are shown in the next tables.

Tapered Bore
Double row spherical roller bearings are manufactured either with cylindrical or with tapered bore (K) with
taper ratio 1:12. Bearings with tapered bore are mounted either straight on tapered journal or on cylindrical
journal by means of adapter sleeves or withdrawal sleeves. These bearings can also be supplied with tapered
bore of taper ratio 1:30 (K30).
Self-Alignment
Double row spherical roller bearings can be tilted off the central position, without impairing their correct function. Values of permitted tilting are shown in the table:
Cages
Double row spherical roller bearings are manufactured in various design executions, with pressed steel sheet
cages (J) , or machined brass cages (M) .Cages can be centered by rolling elements, by inner rings or by outer
ring raceway. Upon client’s request cages in other non-standard executions may also be supplied. Bearings in
EJ and CJ execution can be delivered also with JTN design. This design increases limiting speed frequency
by 10 %.

Bearings According to Special Technical Conditions
Bearings can also be manufactured according to special conditions agreed upon with the buyer. Such bearings are marked by supplementary designation TPF.
Connecting Surfaces Dimensions
Bearing rings may bear only on facial resting surface on the shaft or on the housing but not on the rounding.
Maximum radius of connected parts ra must therefore be smaller than the minimum dimension of rounding
of bearing rings rsmin.
Operating Temperature Effect on Bearings Material
All spherical roller bearings pass special heat treatment permitting their use under operating temperature up
to 200 °C without inadmissible dimensional changes.
Operating Temperature and Axial Load
Thanks to their inner design the bearings exposed to radial load can accommodate a sizeable axial load too.
In case Fa / Fr > e (see bearings tables), it is recommended to shorten the re-lubrication intervals in grease
lubrication. Operating temperature may be a limiting factor as far as the axial load is concerned. In such a case
we recommend to contact the Technical Consultation Services department of ZKL Vyzkum a vyvoj, a.s., who is
prepared to evaluate suitability of selected bearing for particular operating conditions and mounting.
Axial Load Rating of Bearings Mounted on Adapter Sleeves
When mounting spherical roller bearings on plain shafts by means of adapter sleeves, the magnitude of axial
load accommodated by the bearing depends on friction between the shaft and sleeve. Provided the bearings
are properly mounted, we may calculate the permissible axial load from this relation:
Fap = 3 · B · d
where
Fap B
d
. . . maximum permissible axial load [N]
. . . bearing width [mm]
. . . bearing bore diameter [mm]
Minimum Load
Rolling bearings with point and linear contact must be exposed to certain minimum load to secure their
trouble-free operation. This applies to spherical roller bearings as well and particularly for operation at high
speeds, when inertial forces of spherical rollers and of cage, plus friction in lubricant may have adverse influence on rolling and may result in damage of spherical rollers and of raceways. The needed minimum load for
such cases can be estimated from this relation:
Frm = 0,02 · Cr
where
Frm Cr . . . minimum radial load [N]
. . . basic dynamic load rating [N]
As a rule the mass of parts accommodated by the bearing along with external acting forces exceed the required minimum load. Should it not be the case, the bearing must be loaded by a supplementary force, such
as by belt tightening, by higher torque at idle run or similar.
Dynamic Load
Basic Dynamic Load Rating
The basic dynamic load rating is a non-variable load under which the bearing reaches one million of revolutions. For radial bearings the basic radial load rating Cr refers to purely radial load (for thrust bearings the basic
axial load rating Ca applies to purely axial load acting in bearing axis). Basic dynamic load rating magnitude
depends on bearing dimension, number of rolling elements, bearing material and design. Values of basic
dynamic load rating are specified in compliance with ISO 281.
0 0 8
Equivalent Dynamic Load
For calculation of the service life it is necessary first to convert the real acting load to equivalent load, i.e. imaginary constant load corresponding to preconditions for calculation of basic dynamic load ratings and having
identical influence on bearing service life as a real acting load. Only then this load can be used for calculation of
C / P relation. For correct calculation we must know most precisely the external forces acting on the bearing.
Radial Bearings
Radial equivalent dynamic load is an imaginary value which can be determined at combined load (at simultaneous radial and axial loads) by these equations:
Per = Fr + Y1 · Fa
for Fa / Fr ≤ e
Per = 0,67 · Fr + Y2 · Fa
for Fa / Fr > e
where
Per Fr Fa e, Y1, Y2
. . . radial equivalent dynamic load [N]
. . . radial load [N]
. . . axial load [N]
. . . values of e, Y1, Y2 coefficients are shown in tabular part.
Static Load
Basic Static Load Rating
When a bearing is exposed to load at standstill or at very slow rotation, at oscillation or when a bearing is
exposed to impacts and forces for a period shorter than one single revolution, we cannot define permissible
bearing load by dynamic fatigue of functional surfaces but by permissible permanent deformations of raceways and of rolling elements. The values of basic radial static load rating Cor (and of basic axial static load rating Coa for spherical roller thrust bearings) were determined in conformity with the international standard ISO
76. Basic static load rating is the load which causes total plastic deformation in the extent of 1·10-4 of rolling element diameter in contact spot of the most loaded rolling element in central part of contact area between the
rolling element and raceway. Under normal lubricating conditions this value corresponds to maximum contact
load of approx. 4000 Mpa. The safety criterion regarding occurrence of extremely great plastic deformations
is the safety coefficient at static load so.
C
so = ____or
Poe
where
Cor Poe so . . . basic radial static load rating [N]
. . . equivalent static load [N]
. . . static safety
High value of static safety is advisable for bearings requiring easy revolving and smooth run; where lesser
requirements of smooth run exist, lower so coefficient values will do.
Determination of so coefficient values is mostly based on practice and experience.
Equivalent Static Load
Relation of equivalent static load with real acting load and its definition is analogous as in equivalent dynamic load.
Poer = Fr + Yo Fa
where
Poer Fr Fa Yo
. . . radial equivalent static load [N]
. . . value of Yo coefficient is shown in tabular part.
0 0 9
Limiting Speed Frequency
Limiting Speed Frequency shown in catalogue table part is the maximum number of revolutions at which the
– bearing operates with a certain safety measure faultlessly under the following operating conditions:
– bearing load corresponds to service life L10h ~
= 100 000 hours
– axial element of forces magnitude Fa loading spherical roller radial bearing reaches 25% of radial component force Fr at maximum
– bearings are manufactured with normal tolerance class, with normal radial clearance
– limiting speed frequency for oil lubrication is understood for oil bath lubrication.
If the bearing operates at a higher load than above, it is necessary to rectify the limiting speed frequency. For
instance, if the bearing load corresponds to bearing service life L10h = 20 000 hours, the limiting speed frequency value should be reduced by 3 to 28 percent depending on bearing size (smaller bearings need minor
correction); when the load corresponds to service life of L10h = 5 000 hours, the rectification of limiting speed
frequency ranges between 10 to 65 percent.
Similarly the limiting speed frequency must be reduced if axial load magnitude of radial bearings exceeds 25
percent of force radial element. For instance, if Fa / Fr = 0.6, the limiting speed frequency has to be reduced
by 10%, if Fa / Fr = 2, the limiting speed frequency should be reduced by 26%.
On the other hand, the catalogue limiting speed frequency may be exceeded under certain conditions. For
example, limiting speed frequency of spherical roller radial bearing may be increased, provided these conditions are adhered to:
– bearing load and Fa values correspond to catalogue operating conditions (L10h = 100 000 hours,
relation Fa / Fr does not exceed the value of 2.5)
– adequately efficient oil circulation lubrication is secured
– the bearing and all parts relating to it are manufactured with higher accuracy
– the bearing of higher radial clearance (C3) is used.
Whenever the value of limiting speed frequency of bearings, operating under other conditions than that ruling
for limiting speed frequency shown in catalogue table part, needs to be determined, we recommend to consult
Technical and Consulting Services department of ZKL – Vyzkum a vyvoj, a. s. for advice.
Lubrication of Bearings
Grease Lubrication
Lubrication by grease has a number of practical advantages in comparison with oil lubrication and therefore
it is preferred wherever this lubrication method can be applied. As a rule mounting designs of bearings lubricated by grease are simple, costs of sealing the bearing space are lower than for oil lubrication and risk of
lubricant escape is not so great compared with oil lubrication.
At first mounting the inner bearing space is filled by grease fully, while the free space round the bearing is filled
just to one third and not more than to its half. In order to prevent possible contamination or other degradation
of lubricant in the process of mounting we recommend to lubricate the bearings only after fitting is finished,
whenever possible.
Grease will lose its lubricating properties after certain time. Main factors influencing grease life are:
– lubricant quality
– bearing size
– operating speed
– operating temperature
– working environment
0 1 0
It is therefore necessary to re-lubricate the bearings regularly. The recommended re-lubrication interval length tf
can be read in the following graph specifying its value in dependence to operating speed n and bearing bore
diameter d. This diagram applies to these operating conditions:
– bearing load does not exceed 15 percent of basic dynamic load rating
– grease of standard quality is used
– bearing outer ring operating temperature is 70 °C at maximum
– bearing in mounted on horizontal shaft.
If operating temperature exceeds 70 °C, the re-lubrication interval becomes shorter – to its half for each 15 °C
exceeding 70 °C temperature. Contrary to it, at a temperature below 40 °C it is possible to lengthen the re-lubrication interval twice as much. In respect of bearings fitted on vertical shafts we recommend to reduce tf shown
in diagram to its half.
Lubricant quantity Q needed for bearing re-lubrication can be determined either according to the instruction of
manufacturer of the equipment in which the bearing is installed, or according to the following relation:
Q = 0.005 ∙ D ∙ B
where
Q
D
B
. . .lubricant quantity [g]
. . .outer bearing diameter [mm]
. . .bearing width [mm]
0 1

Best method of grease application into the bearing is the use of a lubricating device – grease gun. In respect
of W33 bearings the most convenient way (provided the mounting arrangement allows it) is to apply grease
through outer ring holes.
When a bearing operates at a rather high speed, i.e. frequent re-lubrication is needed, a risk of lubricant stacking in bearing space exists. Such lubricant should be removed after a certain time. For this purpose so called
lubricant slinger being a part of mounting design usefully serves. When using lubricant slinger with new series
of spherical roller bearings operating at higher speeds a rich lubrication must be applied at the operation start.
One hour after new bearing start and 24 hours after again a triple grease quantity should be applied.
Important note: always use the same type of grease at re-lubrication as that applied in the bearing originally.
Never mix different greases unless you are sure of their compatibility. Since mixing of various greases cannot
be absolutely excluded in regular practice, we may use with relatively no consequences the mixtures of:
– greases with identical thickener
– lithium / calcium soap based greases
– calcium / bentonite based greases.
Combinations of following greases are inappropriate:
– sodium / lithium
– sodium / calcium
– sodium / aluminum
– sodium / bentonite
– aluminum / bentonite.
When mixing such greases their structure may become altered, in addition to that acute softening of the
grease may occur. Should there exist the necessity to change to another type of grease, re-lubrication must
be made by a great quantity of lubricant (grease flushing) whenever the mounting design allows it. Next relubrication has to be made at a shorter time interval.
Overview of grease is shown in the table:
0 1 2
Oil Lubrication
Lubrication of bearings by oil is used mostly in following cases:
– re-lubrication intervals by grease are too short
– bearing operating temperature is too high and thus use of grease is unsuitable
– the entire unit (such as the gearbox) is lubricated by oil.
Spherical roller bearings are lubricated either by oil bath lubrication, when oil level is maintained in the height
of the bearing lowest rolling element center, or by oil circulation lubrication. As a rule rolling bearings are lubricated by mineral oils of good chemical stability. Appropriate mineral oil reference viscosity υ1 is determined
from the next diagram, in dependence on bearing mean diameter:
ds = (D + d) / 2
where
ds D d . . . bearing mean diameter [mm]
. . . bearing outer diameter [mm]
. . . bore diameter [mm]
If operating temperature t of the bearing is known or can be established, we can determine the operating viscosity υ at internationally standardized reference temperature of 40°C, needed for calculation of viscosity ratio:
κ = υ / υ1
where
κ
υ υ1 . . . viscosity ratio
. . . operating viscosity [mm2.s-1]
. . . reference viscosity [mm2.s-1]
If κ is smaller than 1, it is advisable to use oils with so-called EP additives to prevent caking of metallic parts
in the contact point at local temperature rise). When κ value falls below 0.4, the use of oil with EP additives
is inevitable.

Mounting and Dismounting of Spherical Roller Bearings
Workplace cleanness, i.e. both cleanness of bearings and lubricant and of further components of the mounting and of mounting devices, is the principal prerequisite of correct mounting and dismounting. Bearings
should be removed from their protective packing not until but shortly before mounting.
Mounting of Bearings with Cylindrical Bore
Bearings may be mounted on journals or into housings bores either under cold or hot mounting process. It is
recommended to cold mount rather smaller bearings. The force necessary for mounting is applied either by
a press or by hammer strokes. We recommend the use a mechanical or hydraulic press instead of striking,
wherever possible. In both cases an assembly jig should be applied on bearing ring just installed; direct strikes
must not be thrown on bearing rings! The installing force must not be transferred over rolling elements. The
tube-shape assembly jig should lean on the ring being mounted, eventually on both rings simultaneously.
Force needed for mounting grows with the bearing size and therefore larger bearings must be hot mounted.
The most frequent heating methods are
– in oil bath
– induction heating
– in heating furnace.
Bearings are heated to the temperature of maximum 100 °C. Heating the bearings by welding equipment
open flame is prohibited.
Mounting of Bearings with Tapered Bore
Bearings with tapered bore are fitted on the shaft by adapter or withdrawal sleeves, or directly on tapered
journal.
Sufficiently reliable fitting of inner ring is checked at mounting by measuring of reduced bearing radial clearance (using feeler gauges), or by measurement of inner ring axial offset length on the journal or on adapter
/ withdrawal sleeve. The initial position for measurement of axial offset is such position at which contact surfaces of the ring and of the shaft (or journal) seat against each other on the whole seating surface. The values
needed for mounting are shown in the next table.
Inner rings may be installed in following ways:
– by striking the assembly sleeve
– by means of KM nut and assembly spanner
– by means of special hydraulic nut
– by hot mounting.
Bearings with tapered bore are mounted on the shaft always with an offset. The offset magnitude is measured
either by reduced radial clearance of mounted bearing or by axial displacement of the inner ring on tapered
journal. In respect of double row spherical roller bearings we recommend to measure the radial clearance
decrease (reduction). Simple checking the axial displacement (offset) is allowed for small size bearings or
in limited space conditions, anyhow this requires good experience to define the initial starting position. For
measurement of radial clearance before, during and after installation the common feeler gauges are used.
Clearance should be measured between outer ring raceway and unloaded spherical roller in upper part of the
bearing. Prior to measuring the bearing should be turned repeatedly so that the rollers settle down to correct
position. When measuring, press the spherical roller slightly to centering ring (according to design solution)
between both roller rows. The measured radial clearance value must be identical for both rows of spherical
rollers. Recommended values of radial clearance reduction and of axial offset for spherical roller bearings with
tapered bore are shown in the next table. If this recommendation is adhered to, the offset is fully adequate
(particularly for reaching the upper limit of radial clearance reduction), see table.

Dismounting of Bearings
Bearings with cylindrical bore are dismounted by using mechanical pullers (in case of small and medium
sized bearings) or by pressure oil (medium and large bearings). As for the bearings fitted on tapered journal,
mechanical pullers serve for small bearings dismounting only while medium sized and large bearings need
pressure oil. Small and medium sized bearings fitted on adapter sleeve are removed by withdrawal sleeve, for
medium sized and large bearings fitted on adapter sleeves special hydraulic nut should be used. Small and
medium sized bearings fitted on withdrawal sleeves are dismounted by means of KM nut and mounting spanner, for large bearings special hydraulic nut should be used.

SPHERICAL ROLLER THRUST BEARINGS
Spherical roller thrust bearings comprise a consistent, entire manufacturing program both in dimensional and
design series 292, 293 and 294, being in compliance with the international standards ISO by their design and
manufacturing process. Quality management system of the whole manufacturing process of spherical roller
thrust bearings is certified according to international standards series 9000.
Contrary to other thrust bearings the spherical roller thrust bearings loads are transferred from one raceway to
the other under certain angle; this enables to accommodate also radial load in addition to axial load. Spherical roller thrust bearings are separable, therefore the shaft ring with cage and spherical rollers and housing
(outer) ring can be installed individually. Another important feature of these bearings is their ability to tilt, which
allows the possibility of alignment of shaft deflection and of verticality deviation to the housing.
Spherical roller thrust bearings are produced, in dependence to size and type, in two designs – in standard
and E design. Outstanding feature of bearings of E design are their higher utility parameters, they represent a
new generation of spherical roller thrust bearings. Being of identical main dimensions, they have upper utility
properties. Both designs can be produced with machined brass cage M or with steel sheet cage J.
Should a bearing with machined brass cage, in which acting axial forces were accommodated also by housing for cage centering, be replaced by bearing with pressed steel sheet cage, a distance ring must be inserted
between shaft ring and shaft shoulder.
The inner space of spherical roller thrust bearings can be efficiently utilized. Therefore they are suitable for
accommodation of great load at relatively high speed frequency. The bearings are capable to accommodate
in addition to axial load also certain radial forces, anyhow these must be of smaller value than 55 percent
of simultaneously acting axial force. Housing ring spherical raceway enables to align verticality deviations
between the shaft and housing.
For their high utility values the spherical roller thrust bearings find wide application in many fields and industrial sectors. They are mainly used in the following installations:
– medium and heavy-duty forming machines
– ship drive shafts
– drilling rigs of all types and sizes
– medium and heavy-duty cranes including crane hooks
– pumps of medium and large sizes and capacities
– mining tunnelling machines and mining engineering
– heavy load swivelling turntables of installations in open pit mines and stone quarries
– power plant engineering (turbines, generating sets, electric motors).

Boundary Dimensions
Boundary dimensions of spherical roller thrust bearings shown in dimensional tables comply with international dimensional plan ISO.
Self Alignment
Design of spherical roller thrust bearings allows tilting and thus alignment of shaft verticality deviation to rolling
elements, while shaft deflection (to certain magnitude) has no influence on bearing operation. Under normal
acting load Fa + 2,7·Fr = 0,05·Coa, shaft ring rotation, constant verticality deviations and usual operating conditions the tilting of spherical roller thrust bearings off central position is allowed by values shown in the table,
without impairing their correct function:
Under growing load the permitted tilting diminishes. For instance, under load Fa + 2,7·Fr = 0,15·Coa the permitted tilting of all bearing types is approx. 1.5°. Taking advantage of permitted tilting depends also on sealing
type and arrangement design.
Cages
Spherical roller thrust bearings in standard version have machined brass cages centered by shaft ring steel
bush and bear designation M. The version with steel sheet cage centered by shaft ring are marked by letter
J. Spherical roller thrust bearings with steel sheet cage are interchangeable with bearings with brass cage,
anyhow, when replacing brass cage bearings with bearings with steel sheet cage bearings it is necessary to
use distance rings (see drawing in tabular part).
Review of Bearings Executions

Bearing rings may bear only on facial resting surface on shaft or in housing but not on the transient rounding.
Maximum radius of connected parts ra ma must therefore be smaller than the minimum dimension
of bearing rings rounding rs.
Tolerance
Spherical roller thrust bearings are generally manufactured in normal tolerance class P0 (this symbol is not
shown in the designation). The limiting tolerance values are shown in ISO 492. Production of bearings of
higher tolerance class needs to be negotiated with the manufacturer.

Operating Temperature Effect on Bearings Material
All ZKL spherical roller thrust bearings pass special heat treatment permitting their use under operating temperature up to +200 °C without inadmissible dimensional changes.
Design of Connecting Parts
Connecting dimensions da and Da shown in dimensional tables apply for loads up to Fa = 0.1·Coa. Should
a greater load act on the bearing, we recommend to rest both the shaft and housing rings by rings entire
facial surfaces (da = d1 a Da = D1) and simultaneously to support the housing ring radially too. In such cases
it is desirable to contact the technical and Consulting Services department of ZKL – Vyzkum a vyvoj, a. s. for
advice. When using the bearings of J, EJ design with steel sheet cages it is appropriate to enlarge the housing
bore near to the cage to prevent thus contact of housing with cage at bearing tilt. Recommended diameter
value of this recess is D + 15 mm for bearings of outer diameter up to 380 mm (inclusive) and D + 20 mm for
larger bearings.
Lubrication
We recommend to generally lubricate spherical roller thrust bearings by oil. Only under very low speed frequency and small load, when bearings with steel sheet cage are used, lubrication by grease may be chosen.
When using grease, the shaft in horizontal position is more suitable than vertical. The permissible speed frequency of vertically oriented shaft lubricated by grease is just a half of a shaft positioned horizontally.
The inner design of spherical roller thrust bearings develops a pumping effect under operation, which can be
found useful under specific circumstances and which should be taken in consideration when designing the
lubrication and sealing
Minimum Load
Rolling bearings under operation must be exposed to certain minimum load to secure their satisfactory operation. This applies to spherical roller thrust bearings as well and particularly for operation at higher speeds,
when inertial forces of spherical rollers and of cage, plus friction in lubricant may have adverse influence on
rolling and may result in damage of rings raceways and of spherical rollers by slipping.
The needed minimum load for such cases can be estimated from this relation:
Fam = 1.8 · Fr + M ·
where
Fam
Fr
M
n
n
(1000
)
____
. . . minimum axial load [N]
. . . radial element of acting combined load [N]
. . . minimum load coefficient – see bearing tables
. . . speed frequency [min-1]
If 1.8 · Fr < 0,0005 · Coa, it is necessary to substitute in the above equation 1.8·Fr by 0.0005·Coa.
Coa
. . . basic static load rating [N]
As a rule the mass of parts accommodated by the bearing along with external acting forces exceed the required minimum load. Should it not be the case, the bearing must be loaded by a supplementary force, such
as by springs.
0 4 3
Equivalent Dynamic Load
Spherical roller thrust bearings can accommodate also radial load in a certain extent, but only under a simultaneously acting axial load. On condition that Fr ≤ 0.55·Fa, it is established that
Pea = Fa + 1.2 · Fr
where
Pea
Fa
Fr
. . . equivalent dynamic load [N]
If the mounting is arranged so that the axial and radial run-outs can be aligned by relative motions between
rings, and provided that
Fr ≤ 0.55 · Fa
potom Pea = 0.88 · (Fa + 1.2 · Fr)
If Fr > 0.55 Fa, please kindly contact Technical and Consulting Services department of ZKL – Vyzkum a vyvoj,
a. s., who can suggest a suitable solution of the problem.
Equivalent Static Load
For spherical roller thrust bearings it is established (on condition that Fr ≤ 0.55·Fa) that
Poae = Fa + 2.7 · Fr
If Fr > 0.55 Fa, please kindly contact Technical and Consulting Services department of ZKL – Vyzkum a vyvoj,
a. s., who can suggest a suitable solution of the problem.
