optibelt reD POWer 3 high PerFOrMance WeDge BelTs
structure
optibelt rED POWEr 3 wedge belts:
Chloroprene compound with transverse
oriented fiber
Polyester tension cord/
maintenance-free
oriented fiber
application areas
optibelt rED POWEr 3 wedge belts were especially
developed for mechanical engineering. The application
areas include compressors, pumps, presses, fans and other
heavy duty drives.
standardisation/Dimensions
optibelt rED POWEr 3 wedge belts in the profiles SPz, SPA,
SPB, SPC, 3V/9n, 5V/15n and 8V/25n are standardised
according to DIn 7753 Part 1, ISO 4184 and ArPm/mPTA.
Abrasion-resistant
cover fabric
The tension cord consists of a special polyester cord. Due to
the special processing of the tension cord the optibelt rED
POWEr 3 wedge belt is very low-stretch and maintenancefree, so that re-tensioning is not necessary.
The transverse fibre mixture on top of and under the tension
cord guarantees a high dynamic load of the belt and
ensures great flexibility. The cover fabric is highly flexible
and abrasion-proof.
Properties
The optibelt rED POWEr 3 is maintenance-free due to the
high quality components and the special production method.
The production processes are continuously monitored using
state-of-the-art static and dynamic testing devices. The
optibelt rED POWEr 3 is suitable for the application in
drives with idler pulleys due to its special construction.
The optibelt rED POWEr 3 has the following properties:
• maintenance-free
• Powerful
• Cost-effective
• S=C Plus usable in sets
• Environmentally friendly
• Electrically conductive according to ISO 1813
• Oil-resistant
• Heat-resistant
• Dust-protected as standard
On request with acceptance test certificate according to
En 1020 “3.1.B“.
V-belt tensioning
For the initial installation of optibelt rED POWEr 3 V-belts,
the same methods are used as for standard Optibelt V-belts.
The tension values are to be calculated on the same basis or
to be taken from the table on page 146. Once correctly
tensioned optibelt rED POWEr 3 V-belts need no
re-tensioning.

PrODucT DescriPTiOn
optibelt Blue POWer high PerFOrMance WeDge BelTs
structure/Properties
optibelt BLuE POWEr wedge belts:
oriented fiber
optibelt BLuE POWEr wedge belts in the profiles SPz, SPA,
SPB, SPC, 3V/9n, 5V/15n and 8V/25n are standardised
according to DIn 7753 Part 1, ISO 4184 and ArPm/mPTA.
Aramid tension cord/
maintenance-free
oriented fiber
Abrasion-resistant
cover fabric
The aramid tension cord has extremely low stretch compared
to common materials such as polyester. The breaking
strength is almost twice as high with the same cord diameter. nevertheless, the fibre is extremely flexible.
The high quality specially prepared aramid tension cord is
embedded in a rubber compound. It is supported by the top
and bottom structures. These consist of a polychloroprene
rubber compound with tranverse fibres.
The abrasion-proof cover fabric is coated with a special
rubber compound and covers the whole belt. The V-belt is
electrically conductive according to ISO 1813
application areas
optibelt BLuE POWEr belts are mainly used when
• highest power transmission levels are required
• there are limited design dimensions
• there is only little installation and tensioning space
• high temperature influences occur
This way, a much better performance is guaranteed e. g.
with the same number of belts. Even the operation of once
critical drives is now largely free of risk. Higher load limits
are now safety zones. Thus optibelt BLuE POWEr belts are
mainly implemented in heavily loaded drives:
• in critical drives in mechanical engineering
• in special machines
• in agricultural machinery
application
Attention: When retro-fitting existing drives please let
Optibelt check the tension. As part of this description not all
criteria can be dealt with. Please consult our Application
Engineering Department.

PrODucT DescriPTiOn
optibelt sK high PerFOrMance WeDge BelTs
Din 7753 ParT 1 / isO 4184
structure
optibelt SK high performance wedge belts consist of:
Top layer
Tension cord
Core
Cover fabric
The polyester tension cord is standard for all profiles and
cross sections, with cord constructions matching the requirements of each profile. The cord is specially impregnated and
then embedded in a special rubber compound homogenously bonding with the top layer and the core.
Due to special processing, the optibelt SK wedge belt is
extremely low-stretch. Thus we were able to reduce our
recommendation values for minimum axial distance significantly – even dropping below the DIn/ISO requirements.
The fabric cover is treated with a wear-resistant rubber
compound. This makes the belt resistant to oil, hot and cold
temperatures and to the effects of dust.
application areas
optibelt SK wedge belts in the profiles SPz, SPA, SPB and
SPC were specially developed for all industrial applications
from lightly loaded drives, such as those for pumps, up to
heavily loaded mills and even stone crusher drives.
optibelt SK wedge belts SPz, SPA, SPB and SPC comply
with the standards of DIn 7753 and ISO 4184.
The ISO standards specify the datum width as a basis for
the standardisation of V-belts and grooves.
The staggering of the datum lengths is implemented according to DIn 7753 Part 1 corresponding to the standard
number sequence r 40. In exceptional cases also corresponding to standard number sequence r 20.
For many years, our product range has comprised serial
production datum lengths of standard number sequence
r 40 and beyond.
note: Electrically conductive according to ISO 1813.
Properties
The use of the best materials and the most advanced
production methods result in this high performance drive
element, the optibelt SK wedge belt. The production processes are continuously monitored using state-of-the-art static
and dynamic testing devices.
optibelt SK high power wedge belts exceed classic V-belts
according to DIn 2215 thanks to the following characteristics:
• Substantially lower width compared to classic V-belt
drives that have the same power rating (height to width
ratio of approximately 1 : 1.2). Due to the available space
gained by this, the costs for a complete drive with
optibelt SK high performance wedge belts are lower than
a design with DIn 2215 V-belts.
• Bigger friction surface lowers the centrifugal force and
permits belt speeds of up to 42 m/sec.
• much more elastic, therefore bigger flex rate allowed.
• Little deformation of the belt cross-section when running in
grooves, therefore balanced pressure on the belt edges.
These characteristics allow for a significantly better performance than V-belts DIn 2212 with approximately the same
top widths. Therefore, we recommend equipping all new
drives with optibelt SK wedge belts.

The three wedge belt profiles standardised in the uSA are
3V/9n, 5V/15n and 8V/25n. The cross section dimensions of these belts and the according length only partially
conform to the profiles and lengths of the wedge belts
DIn 7753 Part 1.
The profile 3V/9n roughly corresponds to SPz; and
5V/15n to profile SPB. There is no comparable DIn/ISO
wedge belt profile for 8V/25n. It is possible to use belts in
profile 3V/9n and 5V/15n in SPz-z/10 or SPB-B/17
pulleys, respectively; but the use of SPz or SPB belts in
ArPm/mPTA standard pulleys is not generally recommended. The top width of the American pulley grooves is smaller
than that of the corresponding DIn/ ISO pulleys. This can
cause wear on the upper edges of SPz and SPB belts and
can lead to premature failure.
Due to its cross section, the optibelt SK wedge belt in SPB
profile is also suitable for 5V/15n pulleys.
The belt length designation refers to the effective outside
length.
Example:

application examples
The use of optibelt SK wedge belt drives in profiles 3V/9n
and 5V/15n is recommended for machines exported to
countries such as the uSA and Canada where these belt
profiles are standardised and predominantly used.
Profile 8V/25n is primarily employed in very heavy duty
drives such as mills or stone crushers. As these wedge belts
transmit very high levels of power, they can sometimes form
a more compact drive than the SPC profile.
For this reason, the 8V/25n profile has continued to be
used in Europe for such applications. A further advantage is
the fact that single wedge belts can be replaced by kraftbands, without changing the pulley geometry, in case
unexpected belt vibration problems develop.
Drive calculation
Drive calculations follow the procedures described in this
manual. The power value of the SPz applies for drives with
the 3V/9n profile. The value of the SPB profile applies for
5V/15n. The datum diameters of the SPz and SPB wedge
belts have to be the same as the external diameters of the
3V/9n and 5V/15n. Slight mathematical differences in the
rotational frequency and transmission have no practical
influence. Slight differences in the theoretical drive speed
and the speed ratio are not significant in practice.

PrODucT DescriPTiOn
optibelt VB classic V-BelTs
Din 2215 / isO 4184
optibelt VB classic V-belts are manufactured using the same
production processes as those for optibelt SK high performance wedge belts.
Top layer
Core
For these applications special belt constructions and calculation methods are required which are not included in this
manual. In these cases we ask you to give us the according
drive data.
optibelt VB classic V-belts in the profiles y/6, z/10, A/13,
B/17, C/22, D/32 and E/40 are standardised according
to DIn 2215 and ISO 4184.
Further, non-standardised ISO profiles 5, 8, 20 and 25 are
available. These profiles should however not be used due to
reasons of exchangeability and rationalisation.
the iSo standard 4184 specifies the datum length
for measuring the belt length. The former belt
designation of the inside length li is replaced by
the datum length ld. For the conversion factors
from pitch to inside length, please see page 169.
Cover fabric
The components used are perfectly suited to the power
ratings Pn. These values are far above those given by
DIn 2218. Thus the operational safety in existing drives is
increased and overloading is avoided.
• optibelt VB classic V-belts have a height-width ratio of
1:1.6.
• The maximum belt speed vmax = 30 m/s should not be
exceeded.
• The allowed flexibility rate is far below that of wedge
belts. It is fB max = 80 s-1.
application areas
optibelt VB classic V-belts are mainly employed as
replacement parts for industrial drives. For new drives, the
use of high performance wedge belts is almost always
recommended due to reasons of space and cost. However,
special drives such as V-flat drives can often only be
operated with classic V-belts. In special constructions,
optibelt VB classic V-belts tackle difficult drives in the
gardening sector and in agricultural machinery.

Belt tension / Static shaft load
Belt tension and static shaft load are calculated in the same
way as for wrapped belts. When dealing with the same
geometric ratios, the shaft load does not exceed that of
wrapped belts although the quantity of the belts is often less.
Therefore, only the individual V-belt requires higher tension
than wrapped belts.
The precise edges of the optibelt SUPER X-POWER M=S
V-belt ensure uniform seating in the pulley grooves, resulting
in smoother running.
Drive calculation
Drive design using optibelt SUPER X-POWER M=S belts

The advantages of optibelt SuPEr TX m=S V-belts can best
be seen when dealing with
• extremely high power requirements
• higher ambient temperatures
In these cases the use of wrapped V-belts is uneconomic and
not recommended.
optibelt SuPEr TX m=S allows for drive ratios i = 1:12.
multi-stage drives can be eliminated.
optibelt SuPEr TX m=S V-belts in profiles zX/X10, AX/X13,
BX/X17 and CX/X22 offer the best technical and economic
solutions under these conditions due to their high quality
perfectly harmonised materials.
optibelt SuPEr TX m=S consist of:
Cover fabric
Embedding compound
Belt base
moulded cogs
The belt base consists of a polychloroprene rubber compound with traverse fibres which support the tension cord.
This results in
• significant flexing rate
• extreme traverse stability
• significantly improved wear resistance and
slip resistance
• electrically conductive according to DIn 1813
• low stretch
The specially prepared tension cord is embedded in a
special compound. Even with high dynamic loads a perfect
adhesion between all components is assured.
The fabric layers of the upper structure support the tension
cord. The fibre-reinforced substructure combined with the
Optibelt tension cord and the moulded cogs allows for a
higher dynamic power transmission.
The moulded cogs decrease the flexing resistance, resulting
in an excellent flexing rate. Thus, much smaller pulleys can
be used compared to common wrapped V-belts.
Due to the use of high quality polychloroprene rubber
compounds, the optibelt SuPEr TX m=S has a higher oil
and heat-resistance than wrapped V-belts.
As high power transmission is possible, even with small
pulley diameters and high engine speed, weight and space
can be reduced thus also substantially reducing costs.

optibelt VariO POWer variable speed belts –
raw edge, cogged
optibelt VariO POWer variable speed belts –
raw edge, Double-sided
Increasing demands on variable speed belts due to the
continuous increase of power transmission levels initiated
the development of the raw edge, cogged variable speed
belts.
The base compound consists of a polychloroprene rubber
compound with traverse fibres. The high quality and
extremely low-stretch polyester or aramid tension cord is
embedded in a rubber compound. It is effectively supported
by an upper and substructure. The special characteristics of
the raw edge, cogged variable speed belt are:
• high power transmission
• excellent flexibility in running direction
• high traverse stability
• exceptionally smooth running
• wear and slip resistance
• long operational life
Further increases in demand on the performance of drive
elements and the trend towards designing ever smaller,
space saving drive units, led to the development of the
Double-sided, raw edge optibelt VArIO POWEr variable
speed belt.
Double-sided Optibelt variable speed belts allow for the
smallest pulley diameters, even below standard recommendations. The Double-sided design improves heat emission,
thereby significantly reducing the belt running temperature.
The production methods and the structure of the belt have
been derived from the raw edge optibelt VArIO POWEr
variable speed belt. Depending upon the application and
application range, this belt can also be equipped with layers
of special cross-cord material in the base compound. The
belt is Double-sided, with the depth and spacing of the cogs
matching with the specific belt profile. The polyester or aramid tension cord ensures ideal power transmission, increased service life, and extremely low-stretch characteristics.
The features of the optibelt VArIO POWEr variable speed
belt can be summarised as follows:
• extremely high acceptance of axial loads
• high flexibility and flexing rate
• better heat emission
• use with small pulley diameters
• high running smoothness with high belt speeds
• long operational life

optibelt DK double-sided V-belts consist of:
This applies to the profiles HAA, HBB, HCC and HDD, in
accordance with the uSA standard ASAE S 211. ...,
thereby ensuring an international interchange.
The reference/nominal length of the optibelt DK doublesided V-belt is measured on the effective/outside diameter
of the measuring pulley. This length equates to the middle
length of the belt.
Conversion factors are as follows:
Profile AA/HAA reference length ≈ centre length – 4 mm
Profile BB/HBB reference length ≈ centre length – 8 mm
Profile CC/HCC reference length ≈ centre length + 3 mm
Profile DD/HDD reference length = centre length!
Experience has shown that in practical use/ordering these

Properties/application areas
The tension cord positioned at the centre of the belt gives
the optibelt DK double-sided V-belts extreme flexibility and
low-stretch properties. Thus, the belt is particularly suitable
for flexing in different directions in the same plane. optibelt
DK double-sided V-belts are used when several pulleys are
arranged in one plane and the direction of one or more of
the driven pulleys has to be changed without crossing the
belts. Due to the position of the tension cord in the neutral
axis and the special shape of the double-sided V-belt, the
tension cord is not subjected to any force other than tension
unlike standard V-belts bent around an outside idler. The
optibelt DK double-sided V-belt comes up to typical serpentine arrangements. Special constructions with different top
surfaces are possible. mainly, double-sided V-belts are used
in agricultural machinery but also in mechanical engineering.
Special profiles
For special applications, we also supply double-sided
V-belts in profiles 22 x 22 and 25 x 22. These are not
standardised.
Drive calculation
Drive calculations for optibelt DK double-sided V-belts differ
from those given in this manual for two pulley drives. multi
pulley calculations are so complicated that they cannot be
presented here.
reference lengths, rotational speeds, transmission ratios and
belt speeds are determined by the reference/outside pulley
diameters.
Our Application Engineering Department will be pleased to
assist you in the design of drives using optibelt DK doublesided V-belts.

The cross dimensions of the optibelt DK double-sided V-belts

sTanDarD PrOPerTies
according to the respective requirements, all
Optibelt V-belts are manufactured using carefully
selected basic materials and continuously updated technical procedures.
regular routine checks during production, elaborate laboratory tests and careful testing of the
raw materials used guarantees a consistently
high level of quality that can be expected from
every Optibelt drive element.
reliability and long service life are considered the
most important criteria.
Oil resistance
The limited oil resistance prevents the
damaging effects of mineral oils and
greases, as long as these substances
are not in permanent contact with the timing belt and/or are
not present in large quantities. Animal and vegetable fats
as well as water-soluble cooling and cutting oils result in a
reduction of the service life. For higher concentrations, we
recommend the use of our optibelt SuPEr X-POWEr m=S or
the special design “05“, respectively.
heat resistance
s=c Plus “setconstant“
This stands for wrapped V-belts that
can be used in a set without measuring.
and here are the advantages:
saves energy, efficiency of up to 97 %
consistent power transmission
incorporates the world famous S=C Plus tolerances:
always at nominal length
extremely low-stretch
longer service life
set code numbers are not required
reduces vibrations with resultant smooth running
requires only minimal adjustment space
reduces self-heating, thus ageing resistant
longer maintenance intervals
simple storage
significant cost reductions
Example of S=C Plus length tolerances for a high
performance wedge belt with 5000 mm datum length:
s=c Plus
Standard V-belts allow ambient
temperatures of up to +70° C. Temperatures exceeding this range lead to
premature ageing and hardening of V-belts. In such cases,
we recommend the use of our special constructions optibelt
rED POWEr 3 or optibelt SuPEr E-POWEr or optibelt
SuPEr X-POWEr. For details see page 23.
Dust protection
Dust enormously reduces the service
life of V-belts. Wear-resistant fabric
covers make Optibelt V-belts resistant
to dust. This is demonstrated by their continuous application
in cement factories, mills, in the stone processing industries,
and in the mining industry.
M=s “Matched sets”
optibelt SuPEr E-POWEr m=S,
optibelt X-POWEr m=S and optibelt
SuPEr TX m=S are raw edge, cogged
V-belts that can be used in sets without measuring. Due to
special production processes the narrowest tolerances can
be achieved so that V-belts of a given nominal length can
be combined without further measurement. The precise
edging of the belt results in smooth running. The even power
transmission of all belts ensures a high efficiency and saves
energy.
Set code numbers are not necessary, there is no set
bundling. As a consequence, storage and costs can be
reduced.
22
The dimension (A) is the tolerance allowed according to DIn
of an individual V-belt with a length of 5000 mm. If you
want to install sets for multi-groove drives, the individual
elements in a set should not deviate more than 6 mm (B).
The tolerance of the optibelt S=C Plus V-belt is considerably

Mining industry
optibelt SK wedge belts and optibelt VB classic V-belts can
be used in underground mining as well as in areas above
ground that are exposed to explosion and fire risks. For
these areas, different national and international testing
specifications and standards apply. Optibelt “mining Belts“
comply with all requirement of “DIn 22100-7“.
smooth running selected V-belts
Drives that require a smooth running – that is variations of
shaft centre distances – such as lathes and grinders, and are
supposed to guarantee a vibration free operation, should be
equipped with Optibelt V-belts with “selected smooth
running“. Fluctuations in the shaft centre distance are
electronically measured on testing machines. The measurements comply with the Optibelt standards or the conditions
agreed upon with our customers.
These Optibelt V-belts in special constructions have different
tension cord types and structures with a variety of rubber
compounds, different fabric qualities and a differing number
of fabric covers and top surfaces.
All special constructions and intermediate lengths must be
ordered in sets or in multiples thereof.
As part of this description not all criteria can be dealt with.

service life
extra heat-resistant V-belts
The service life of standard Optibelt V-belts can be
massively reduced due to the effects of temperature.
In case of ambient temperatures that constantly vary
between +70 °C and +90 °C we recommend optibelt rED
POWEr 3, optibelt SuPEr E-POWEr m=S, optibelt SuPEr
X-POWEr m=S or optibelt SuPEr TX m=S belts. Special
rubber compounds largely prevent premature ageing and
brittleness. In borderline cases, trials are recommended, as
individual drive parameters such as belt speed and pulley
diameter may influence the operational life.
The diagram below illustrates the great impact of ambient
temperature on the operational life of belts. It also presents
the optimised operational life of special constructions in
high temperature ranges compared to standard constructions. However, you cannot expect the same service life as
under normal conditions.
applications with other special constructions
For special applications e.g. in general mechanical engineering, agricultural machinery and horticulture, further
special constructions are also available in intermediate sizes
for
• special drives with tension, back bend and guide idlers
• clutching drives
• shock loads
• extreme operating conditions

Balancing
V-grooved pulleys are statically balanced in accordance
with the guidelines in VDI 2060, as standard:
Quality level G 16; for dia. dd ≤ 400 mm at n =1500 rpm;
for dia. dd > 400 mm at v = 30 m/s.
The pulleys are balanced without keys on smooth balancing
spindles. Machines whose runners are balanced with a
keyway in the shaft end should be ordered as follows:
“Balanced with pilot bore and empty keyway on smooth
balancing spindles without key“.
Balancing in one plane to quality level G 6.3 on request.
We recommend balancing in two planes according to
quality level G 6.3, or finer when v > 30 m/s or the ratio of
datum diameter to face width dd : b2 is < 4 at v > 20 m/s.
In such cases, the operational speed of the pulley must be
given.

sTanDarDs – Design criTeria – TYPes
solid pulley
Plate pulley
spoked pulley
An essential component in V-belt drive systems is the V-belt
pulley, or in short V-pulley. They are primarily manufactured
from cast iron En-GJL-200-DIn En 1561 and are available
with a pilot hole, pre-fabricated hole or with a clamping
bush system. The DIn standard as well as the most important national pulley standards of all industrial nations are
based upon the ISO 4183 standard “Grooved Pulleys for
Classic V-Belts and Wedge Belts”.
V-belt pulleys with grooves for wedge belts according to
DIn 7753 Part 1 are also suitable for classic V-belts with
the same datum width bd according to DIn 2215. These are
known as dual duty pulleys.
• Balancing in two planes (dynamically), quality level
Q 6.3 becomes necessary if:
1. v > 30 m/s or
2. the ratio of datum diameter to pulley face width
dd : b2 < 4 at v > 20 m/s.
example
Deep grooved pulleys
Deep grooved pulleys are employed for special drive
situations such as
• the use of guide idlers,
• twist drives or
• drives subject to severe vibration.

note: The timely replacement of pulleys damaged by
corrosion or erosion prevents premature failure of the belts.
Furthermore, it is important to prevent the belt basis from
direct contact with the groove basis as this can quickly lead
to damage and premature failure (exception: special drives
such as V-flat drives).
The increased groove top width “b1“ and depth “t“ of deep
grooved pulleys improves the running characteristics of the
belt, particularly when entering the groove. Turning over
and running out of the belt are prevented.
Deep grooved pulleys are not suitable for the use
with kraftbands.
When selecting a pulley, the following criteria should be
taken into account:
• use standard pulley diameters.
If design considerations make this impossible, a standard
diameter should, as a minimum requirement, be selected
for the largest pulley in the drive.
• Do not select a pulley smaller than the recommended size
to ensure a longer operational life and overall drive
efficiency.
• If manufacturing your own pulleys, the overall shape and
processing must conform to the relevant standards.
• Grooved pulleys are generally balanced in one plane
(statically) to quality level Q 16 as in VDI 2060.

For drives with several grooves the total of all deviations from the nominal value e for all groove distances of a pulley ± 0.8 mm must not be exceeded.
For further details see ArPm/mPTA.
note
The allowed variations of V-grooved pulleys according to ArPm/mPTA deviate only slightly from the values contained in ISO 5290 “Grooved pulleys
for joint narrow V-belts (Kraftbands)”. Therefore, optibelt KB kraftbands can be used in V-grooved pulleys manufactured according to both standards.
These V-grooved pulleys are also suitable for optibelt SuPEr X-POWEr m=S V-belts.

The international standard ISO 5290 specifies pulley groove
dimensions for belt profiles 3V/9J, 5V/15J, 8V/25J.
The groove top width “b1“ is used as the basic reference
dimension for standardisation of the grooves and joint
V-belts. The pulley groove and joint V-belts are considered
as a single unit in the standard ISO 5290.
The values δ h1 and δ h2 were chosen to ensure that
1. the top cover of the joint belt has no contact with the
outside pulley diameter, in order to prevent the separation of the top cover.
2. the ribs are nevertheless still deep enough inside the
pulley in order to ensure an optimum power transmission.
δh1
For further details please see standard ISO 5290.
1) Tolerance for the centre distance “e” of two adjacent grooves.
2) The sum of all deviations from the nominal dimension “e“ for all groove distances of a pulley must not exceed the given tolerance.
b1 = effective width
da = effective outside diameter
The groove faces must be straight at least to a level
of da – 2 δ h2.

DRIVE CALCULATION
OPTIBELT Nominal Power Rating PN –
Arc of Contact Correction Factor c1
The Optibelt nominal power ratings PN in tables 32 to 68
are based upon an internationally accepted basic formula
and a theoretical belt life of 25,000 hours under ideal
conditions. This formula contains material constants that take
into account the quality of the raw materials used and make
allowances for production methods. Due to the special qualities of Optibelt V-belts, other material constants than those
given in DIN have been taken into account. As a result, the
nominal Optibelt power ratings PN significantly exceed the
ratings given, for wedge belts according to DIN 7753
Part 2 and for classic V-belts according to DIN 2218, for
the same theoretical belt life. The nominal power ratings PN
are based on the smallest loaded pulley in the drive system.
The belt power rating value PN is calculated taking into
account
• the datum diameter of the smaller pulley ddk
• the speed of the smaller pulley nk
• the drive ratio i
• an assumed arc of contact at the smaller pulley of
β = 180°
• a reference belt length for the specific belt profile
In order to account for the actual drive data, based on the
arc of contact and the belt lengths employed, correction
factors for the arc of contact c1 and length c3 have been
introduced. If required, drive calculations can be provided
for any theoretical belt life.
Intermediate values for nominal power rating, arc of contact
and length correction factors can be found via linear
interpolation.
The factor c1 corrects the power rating PN, when the arc of
contact is smaller than 180°, as the PN value is calculated
on the arc of contact β = 180° on the smaller pulley.

DRIVE CALCULATION
LOAD FACTOR c2
The service factor c2 takes account of the daily operating
time and of the type of driver and driven machine. It applies
exclusively to two-pulley drives. Other arrangements such as
drives with tension and guide idlers have not been taken into
consideration. Pages 137-139 provide the relevant basic
design guidelines for drives with more than two pulleys.
Adverse operating conditions (e.g. aggressive dust, particularly high ambient temperatures or the effects of various
substances) have not been taken into account. As it is
practically impossible to cover every conceivable combination of driver/driven machine/operating conditions in a
summary that complies with the relevant standards, the
service factors are approximate values.
In special cases, e.g. increased starting torque (direct on-line
starting of fans), in drives with frequent starts and stops, in
systems subject to exceptional shock loads, or when significant masses are to be accelerated or braked, the service
factor must be increased.
Empirical value:
With a starting torque > 1.8 this figure is to be divided by
1.5 in order to calculate the minimum load factor c2.
Example: Starting torque MA = 3.0; c2 selected 2.0.
Please consult our Applications Engineering Department for
the solution of special problems.

DRIVE CALCULATION
Length factor c3 for OPTIBELT Wedge belts
and kraftbands
The length factor c3 takes into account the flex rate of the
belt based on the reference length for the particular belt
profile.

*Raw edge, cogged V-belts
DRIVE CALCULATION
Guidelines for Selecting the Suitable Profiles
for V-belts and Kraftbands
By using the following diagrams, the most suitable belt
profiles as far as efficiency and size are concerned, can be
selected for a specific application. The most efficient power
transmission and economy is achieved by selecting as large
a pulley diameter as possible for the profile in question. The
limits to be observed are the maximum allowed circumferential speed, namely for
high performance wedge beltsvmax = 55 m/s*;
for classic V-belts
vmax = 30 m/s.
If the circumferential speed is outside this recommendation,
please contact our Application Engineering Department.
Experience has shown that minimum pulley diameters should
be avoided. These drives require a larger number of belts
with wider pulleys and are therefore more expensive.
In borderline cases we recommend using the next smaller
profile belt for the same pulley diameter, as the smaller
profile will often save both cost and space. A further
recommended solution is the use of the raw edge
optibelt SUPER X-POWER M=S V-belts.
Furthermore, we recommend evaluating if the intersection
point in the selection diagram is in the limit values of two
profiles.
Comparing space requirement and costs, the high
performance wedge belt is usually far superior to classic
V-belts in almost all industrial drives. For this reason,
new constructions use high performance wedge belts almost
exclusively. Only in special cases, for replacement parts, or
for V-flat drives or special cases where the application of
classic V-belts is o
bligatory.

V-FlaT DriVes
The V-flat drive comprises one grooved pulley and one flat
pulley. This type of gear can, under certain conditions, be
used for drives with intermittent loading or with large
moments of inertia. As flywheels or flat pulleys are often
126
already present, the costs of the drive can be reduced.
When changing over a flat belt drive to a V-flat drive, it will
usually be economical to continue to use the flat pulley.

V-Flat Drives
Calculating V-flat drives
The calculation of V-flat drives is based on the same method as presented on pages 85 to 87. In order to ensure
reliability and efficiency, the V-flat belt drive must meet the
following requirements:
• The small pulley must always be V-grooved.
• When using single belts, only classic V-belts in profiles
Z/10, A/13, B/17, C/22, D/32, E/40 must be used.
• Wedge belts must never be used as their narrow base
and larger relative height tends to make them turn and
twist.
• All optibelt KB kraftbands – both with wedge belts and
classic V-belts – are particularly suitable for this type of
drive due to their single belt characteristic. Turning over
even under extreme shock load conditions is prevented.
• A V-flat drive is particularly economic when
Da – dd
kf = is between 0.5 and 1.15
a
The optimum drive dimensioning is achieved when
kf = 0.85. If the factor kf is outside the recommended
range, it is more economical to design a standard V-belt
drive.
• The following recommendations result from these
requirements:

• For classic V-belts, the length is calculated using the
datum length Ld, and for kraftbands using the outside
length La. Therefore, the correction factor Dz must be
added to the outside diameter of the flat pulley in order
to approximate the theoretical design diameter.

Product Description
optibelt OPTIMAX HF
Endless high performance flat belts
Structure
The raw material of the optibelt OPTIMAX HF high performance flat belt is polyester yarn. This will be woven to
endless sleeves and then covered with a high-quality rubber
compound on both sides.
optibelt OPTIMAX HF high performance flat belts are
produced in two different types that differ in thickness and
strength.
Type HF 150 is intended for general use, whereas type 075
is only intended for special drives.
Characteristics
optibelt OPTIMAX HF are particularly distinguished by the
following features:
• High flexibility
• Very small pulley diameters (HF 075 from 6 mm)
• High belt speeds
• High efficiency
• Low noise development and low vibration
• Low maintenance requirement
• Good chemical and ozone resistance
• High friction values (0.5 μ)
In addition, the raw materials used guarantee a temperature
resistance of –30 °C to +110 °C. With optibelt OPTIMAX HF
high performance flat belts, belt speeds of up to 50 m/s are
easily possible. No noise and vibrations occur.
Due to its low elongation, this belt can be used even for
drives with fixed centre distance for low power transmission
systems.
Without engendering the risk of a reduced lifetime, idlers
can be used in a flat belt drive. This can be done for
tensioning or power reduction.
The high-quality neoprene rubber compound makes optibelt
OPTIMAX HF high performance flat belts conditionally
resistant to oil, fat, solvent and moisture.
optibelt OPTIMAX HF are electrically conductive; an
ISO 1813 certificate can be issued on request.
Application areas
For power transmission, optibelt OPTIMAX HF belts are
particularly used in drives with a medium torque or high
speeds. Examples of this include: Tool, wood processing,
textile, printing, dyeing as well as agricultural machines,
etc.
For all the machines listed, we recommend type HF 150,
as its low elongation, high strength and sufficient elasticity
largely neutralize any impacts and vibrations that occur.
Type HF 075 is especially useful when high precision is
required where smooth running and tolerances are concerned. It is therefore used for computers and office equipment as well as small devices.
In addition, the HF 075 can be used for small conveying
applications.
A special advantage of this drive element is the low thickness. As a result, very small pulley diameters are possible,
which almost always leads to a considerable cost reduction.
Due to the use of high-quality synthetic materials, a very
high strength is reached despite the low belt thickness.

Base drive service factor c0
The base drive service factor c0 takes into account the type
of drive and driven machine. It applies exclusively to
two-pulley drives and for a daily operating time of less than
ten hours. No special conditions have been taken into
account. Please observe the additional factor c4.
Since it is practically impossible to condense every possible
combination of drive unit, driven machine, and operating
conditions into a standard-compliant short version, the drive
service factors are guide values. ln special cases,
e.g. increased starting torque (direct starting with fans),
drives with a high switching frequency, extraordinary impact load, considerable mass acceleration and deceleration,
the drive service factor must be increased.
In cases of doubt, we recommend that you contact our
consulting engineers.

Arc of contact correction factor c1
The arc of contact correction factor c1 corrects the power
rating PN when the arc of contact of the belt is smaller than
180°, since the PN value of the arc of contact β = 180° was
determined on the small pulley dak.
Additional factor c4
If special conditions need to be taken into account on a
drive, the additional factor c4 is to be added to the base
drive service factor c0.

Tension of flat belts
The correct level of belt tension is of enormous importance
for trouble-free transmission of power and for achieving an
acceptable belt service life.
Often tension which is either too high or too low results in
early belt failure. A belt which is over tensioned often
causes bearing failure in the drive or driven machine.
It has been shown that common tensioning instructions, such
as using the “thumb pressure deflection method”, are not
suitable for obtaining optimum tension for operating at full
efficiency.
Over or undertensioning of the drive can be avoided if the
tension is calculated, set or checked according to the
following method.
Tension through span force
An optimum tension is achieved if a span force of 300 N
per 10 mm belt width is applied for type HF 150.
This belt tension approximately corresponds to an elongation of 0.7 % of the belt length.
Type HF 075 can be tensioned according to the same
method, with the exception that the span force is 150 N per
10 mm belt width and an elongation of 0.8 % of the belt
length can be expected.
The span force can easily be checked on a belt width of up
to 50 mm with the aid of optibelt TT using the frequency
measuring method. If the frequency has been determined,
the span force can be calculated as follows:
T = 4 · k · L2 · f2.
T= Belt tension [kN]
k= Weight per metre per mm belt width [g/m]
L= Belt tension [m]
f = Frequency [Hz]
Checking the tension with a length addition value
The length (L) of the relevant flat belt is measured in an
untensioned condition on the top surface of the belt.
Calculate the length addition value “A” by using the
formula:
A = L · R (elongation value)
R = 0.007 for type HF 150
R = 0.008 for type HF 075
This length addition value A should then be added to the
measured length.
The flat belts are now tensioned until the calculated length is
reached (length + length addition value A). The belt is then
correctly tensioned.
If the drive is to be retensioned, the belt must first be
slackened off so that it can be measured in a tension-free
state.
After that, follow the procedure described above.

Flat belt pulleys are an essential part of the flat belt drive.
They are mainly manufactured of GG 20 cast iron according to Dln 1691 and supplied with a pilot hole, pre-fabricated hole or with a clamping bush system. Other materials,
such as steel or aluminium can also be used depending on
the drive conditions.
When selecting the flat belt pulleys, the following must be
adhered to:
• use standardized pulley diameters. If this is not possible
for structural reasons, a standardized diameter should be
selected for the largest pulley.
• Do not use less than the minimum pulley diameter in the
interest of the belt lifetime and the efficiency of the drive.
Minimum pulley diameter
Type hF 075 = 6 mm
Type hF 150 = 15 mm
• If users produce their own flat belt pulleys, a standardcompliant design and finish must be ensured (DIn 111).
• Flat belt pulleys are generally balanced on a level
(statically), quality grade G 16, according to VDI 2060.
• Balancing on two levels (dynamically), quality grade
G 6.3, becomes necessary if:
1. v > 30 m/s or
2. The ratio of diameter to pulley face width
is d : b < 4 with v > 20 m/s.
• Flanged pulleys should be avoided if possible.

Special Drives
Tension/Guide idlers
Idlers are grooved or flat pulleys that do not transmit any
power in a drive system. Due to the fact that additional
flexing stress is created in the belt, it is recommended that
idlers are only used sparingly under the following conditions
if possible:
•w
ith fixed drive centres in order to produce the required
tension and to take up the maximum possible belt stretch
and wear,
•a
s an idler pulley when dealing with extremely long free
belt spans that are subject to twisting,
•a
s outside idlers where the arc of contact on one of the
loaded pulleys is too low. Their inclusion increases the arc
of contact and often reduces excessive slip or eliminates
the need to increase the number of belts,
Idler configuration
In principle, idlers can be used as inside or outside idlers
depending on the drive situation.
Unless design requirements call for an outside idler, the
inside idler is usually more advantageous. Its diameter can
be kept smaller than that of the outside idler.
Depending on the belt type, inside idlers can either be
grooved or flat pulleys.

required. Because of their single belt characteristics,
optibelt KB kraftbands are particularly suited for these
applications.
If, for the reasons listed above, it is absolutely essential to
employ idlers, the following criteria should be considered
when designing the drive:
• idler configuration
• position of the idler in the belt span
• idler diameter
• idler design
•a
djustment allowance of the idler for installation and
initial and subsequent tensioning of the belt
• correction of the power rating PN
For raw edge V-belts and kraftbands the same requirements
as given in table 79 apply.
Inside idlers reduce the arc of contact on the loaded pulleys
and with it the arc of contact correction factor c1. When
calculating the number of belts, the arc of contact correction
factor should be selected for the position of the idler at the
point of maximum belt stretch (see table 81, page 139).
Outside idlers generally have to be flat pulleys as they
are running on the back of the belt. They increase the arc of
contact. Care must be taken to ensure that the maximum
possible belt stretch is taken up and that contact with the
opposite span is prevented. The reverse bending caused by
outside idlers will lead to a reduction of the belt service life.
Special V-belt constructions on request.
sPecial DriVes
TensiOn/guiDe iDlers
Position of the idler in the belt span
Theoretical power transmission formulas and actual practice
have shown that idlers should, wherever possible, be placed
in the slack side of the drive. The tension idler force can be
reduced very significantly then. A spring loaded idler must
not be employed in a reversing drive as the slack and tight
sides of the drive are constantly changing.
Our Application Engineering Department will be pleased
to assist you when spring loaded idlers present special
problems.

as far as possible
On drives with long belt spans, grooved pulleys are the
preferred choice for inside idlers because with flat pulleys
transverse vibrations and belt turnover can occur.
Minimum diameter for idlers
Inside idlers should not be smaller than the recommended
minimum pulley diameter (dd min) for the belt section
concerned (see page 51, table 14)
tight side
Grooved pulleys can be used as inside idlers anywhere on
the slack side. Where possible, however, the arc of contact
should be the same on both pulleys when the idler reaches
its end position, i.e. belt stretch is at its maximum.
Inside idler ≥ minimum pulley diameter for the belt
section concerned
The presence of an outside idler exposes the belt additionally to a varying bending load. Due to this load, outside
idlers must be at least 1.35 times greater than the minimum
pulley diameter for the particular belt section.
Outside idler ≥ 1.35 · min. pulley diameter for the belt
section concerned

The belt service life is significantly reduced if the minimum
recommended idler diameter is less than the recommended
size. The use of an Optibelt special construction can
significantly improve service life.

Flat pulleys, whether used as inside or outside idlers, are to
be placed as far as possible away from the grooved pulley
on to which the belt runs next. Any alignment errors between the idler and the pulley and the resultant sideways
movement of the belt on the pulley are thus avoided.
138
idler design
Grooved pulleys which are used as idlers can usually have
standard groove dimensions. On drives with too severe
vibration and long drive centre distances, it is recommended
that deep grooved pulleys are used.
Flat pulleys should, if possible, be cylindrical and not
crowned. Flanged pulleys are recommended as belt guides.
The edges formed by the contact surface and pulley flange
should be sharp. round edges encourage the belt to run on
the flanges causing it to turn over.

The use of idlers increases the bending stress in the belts.

Ld = Ldth + 2 y
3. The next largest standard length LdSt should then be
selected. A check should be made, usually on the
drawing, to determine whether the belt can be
adequately tensioned with the idler in the outermost
position. In this idler position, both the standard length
LdSt and the double adjustment x must be taken up
(see pages 82/83).

Drives with crossing belt spans are often simply termed twist
drives. These can be drives where the shafts are not parallel, whose pulleys and idlers are not all arranged on one
plane, or drives with two parallel but counter rotating shafts.
Because of the twisting of the belt, this type of drive requires
a certain degree of lateral bending flexibility. Due to the
cross section of V-belts, flat belts are better suited for this
application. In most cases twist drives use single V-belts, but
drives using belt sets are also possible. The crossing of the
belt spans and the non-aligned entry of the belt into the
pulley leads to a reduction of the belt service life. The entry
and exit angle between the belt and the pulley plane should
not be more than 5°.
quarter twist drive
The term quarter twist drive is used to describe systems
where the shafts are at an angle of 90° to each other.
The ratio i or 1 : i of quarter twist drives should not
exceed 2.5.
quarter twist drive – ratio i or 1 : i < 2.5
quarter twist drive – ratio i or 1 : i > 2.5
140
The required inclination of the shafts and the pulleys relative
to each other and the belt entry and exit angles should be
confirmed by practical tests. In addition, certain critical
drives may have a considerably improved safety factor if
special constructions by Optibelt are used. The most important types of twist drives and the according design guidelines are illustrated below.
Where this is not possible, a two stage drive should be
employed, in which one stage is a standard V-belt drive.

Aramid is an organic polyamide fibre that is manufactured
in a complex chemical process. It may be used wherever
maximum stress resistance and reliability are required. The
processing of this fibre requires the highest level of experience and know-how as well as sophisticated testing facilities. Aramid is used as the tension cord material for highly
loaded V-belts and kraftbands.
structure and properties
Compared to materials commonly used for tension cords
e.g. polyesters, aramid stands out due to its extremely
low-stretch properties.
Its tensile strength is twice as high as that of a standard fibre
in the same thickness.

Despite its extreme strength, this fibre is remarkably flexible
and has sufficient elasticity to absorb shock loads or
vibration.
These properties, which are of special importance for V-belts
and kraftbands, result in huge improvements in comparison
to conventional constructions.

The advantages of Optibelt V-belts and kraftbands with
aramid tension cords are best applicable where
•
•
•
•
high power transmission is required
there is only small installation space
there is little adjustment range
high temperature influences occur
Thus, with the same number of belts and unchanged drive
parameters, significantly higher power levels can be
transmitted without reducing the service life of the belts.
Even drive constructions that have previously had to be
classified as critical may now be considered risk free. From
now on, load limits apply as safety buffer zones; minimal
belt stretch results in virtually maintenance-free running.
For these reasons Optibelt V-belts and kraftbands with
aramid tension cord are to be found on drives with exceptional loading requirements –

BelT TensiOn FOr OPTiBelT V-BelTs
For proper power transmission and for achieving an
acceptable belt service life, the correct belt tension is of the
utmost importance.
Too low or too high belt tension will lead to the premature
failure of the belts. Over tensioning often leads to bearing
failure on the driver or the driven machine. Experience has
shown that unscientific belt tensioning methods, such as the
“thumb pressure method”, are not suitable for applying the
optimum tension to the drive for maximum efficiency. It is
therefore recommended that for each drive the required
static belt tension “T” is calculated using the formulas by
Optibelt. This tension is the lowest possible required by
a drive to transmit the highest power level from the drive,
taking account of the normal amount of slip.
Once the belt has been fitted and the initial tension has
been applied, it should be checked using an Optibelt
tension gauge.
The belt should be monitored regularly during the first hours
of operation. Experience has shown that the first re-tensioning should be carried out after approximately 30 minutes to
four hours operating under full load. In doing so, the initial
stretch is absorbed.
After approximately 24 hours of operation, it is often
recommended to check the drive and re-tension the belts
if necessary, particularly when not continuously run under
full load. The time between checks can be significantly
increased then. Also see our installation and maintenance
advice on pages 158 to 159.
Too high or too low tension of the drive will be avoided if
the belt tension is calculated, set and checked using one of
the following methods.
i. Checking the belt tension by span deflection
This method provides an indirect measurement of the
calculated or actual static belt tension. It is applicable
for belt sections SPz, SPA, SPB, SPC,

III.Belt tensioning via
”length addition value” method
It has become evident that span deflection methods are
not ideal for checking the tension of kraftbands of all
profiles, and of individual belts. The following, very
simple method for the setting and checking of belt tension
is therefore recommended:
Example:
PB= 1136 kW
c1= 0.97
v = 25.91 m/s
Drive arrangement with one set comprising:
2 optibelt KB kraftbands 4-8V 3750/25J 9525 La
2 optibelt KB kraftbands 5-8V 3750/25J 9525 La
1.Calculation of the static belt tension “T“:
T≈
500 · (2.04 – c1) · PB
c1 · z · v
+ k · v2
T≈
500 · (2.04 – 0.97) · 1136
0.97 · 18 · 25.91
+ 0.69 · 25.912 = 1807 N
2.Measure the setting length “M“ of the kraftband or the
single belt, on the top surface of the kraftband or on the
belt top surface when not tensioned. However the belt
can be measured when fitted to the drive, provided that it
is completely without tension.
3.Procedure
a) Install the kraftband or the single belt on the pulleys.
Provisionally tighten the belt in order to seat it into the
pulley grooves.
b) Next, completely slacken the kraftband or the single belt.
c) Mark two lines on the top of the belt, with distance
“M“. The lines must be marked on the free span
length, not where the belt is on the pulley (“M“ should
ideally be 1000 mm minimum or a multiple of it).
Important: The longer the measured profile, the more
accurate the tension setting will be.
4.Calculate the length additional value “A“ using the formula:
A=
“M“ selected 4000 mm
M·R
1000
A=
4000 · 5.5
1000
= 22.0 mm
R = stretch factor from table 84 page 149
5.Tighten the kraftband or the single belt until the length
calculated under point 4 is reached. The drive is now
correctly tensioned.
6.If the drive has to be re-tensioned, the belts have to be
slackened first so that they can be re-measured completely free of tension. After that, the procedure described in
paragraphs 3 to 5 applies.
Tighten the kraftband until the length additional value is
reached. This will set the correct tension.
At initial installation, the static belt tension must
be multiplied by 1.3.

ensures that the dynamic stress that occurs can be absorbed
by the appropriate shafts and bearings of the motor.
However drives with
• electric motors out with the DIn standards
for the determined dependencies of pulley diameter
and power,
• combustion engines,
• turbines as well as
• heavy duty drives such as stone crushers, calenders or
heavily loaded mills
have been found to require determination
of the dynamic bearing load, i.e. the loads that
occur for shafts and bearings on the input or output drive
units.
Precise calculation of the “Dynamic axial load“ prevents
unnecessary costs due to

• premature failure of the bearing,
• breaking of the shaft,
• over dimensioned bearings and shafts.
In the case of 2-pulley drives, the driver and driven shafts
and the bearings are subjected to the same dynamic axial
force, but in opposite directions. When idlers are employed,
the magnitude and the direction of the axial force are
almost always different on each pulley. If the magnitude and
direction of the dynamic axial force is to be determined, a
graphical solution, using a vector diagram for the dynamic
forces in the tight side S1 and the slack side S2, is recommended.
If only the magnitude of the dynamic axial force has to be
determined, this can be achieved using the formula for
“Sa dyn“. Both procedures will be illustrated in the following
example.

This gauge offers a simple method
of belt tensioning.
It helps e. g. mechanics during the maintenance of belt
drives when technical data is not known and the optimum
tension therefore cannot be calculated. This method requires
only knowledge of the diameter of the small pulley and the
belt profile. The Optibelt tension gauge is used to directly
read the belt tension. By reducing or increasing the belt
tension the desired value is achieved.
For different tensioning values, optibelt OPTIKrIK 0, I, II, III

Installation and maintenance support
Safety: B
efore starting any maintenance work, it is extremely important that any machine
components are in a safe position which cannot be changed during maintenance
work. In addition, safety recommendations of the manufacturer are to be strictly
observed.
optibelt KS V-Grooved Pulley with Taper Bush
The V-grooved pulleys are to be
checked for damage and correct dimensions before installation.
Installation
1.All shiny surfaces like bore and tapered surface
of the taper bush as well as the tapered bore of
the pulley have to be cleaned and degreased.
Insert taper bush in hub and align all connecting
bores. Half tapped holes have to face half plain
bores.
2.Stud screws (TB 1008-3030) and/or cap head
screws (TB 3525-5050) should be slightly
greased and screwed in. Do not yet tighten the
screws.
3.Clean and degrease the shaft. Push pulley with
taper bush to the desired position on the shaft.
See alignment of the V-grooved pulley.
4.When using a key, it has to be inserted in the
hub of the shaft first. Between key and bore hub
there needs to be a certain tolerance.
5.With a socket wrench according to DIN 911
stud screws and/or cap head screws have to
be tightened equally using the tightening torque
stated in the table.
6.After a short operating time (0.5 to 1 hour)
check tightening torque of the screws and correct if necessary.
7.In order to prevent the entering of foreign substances, fill empty connection bores with grease.

Horizontal Alignment of Shafts

Note!
Maximum shaft deviation 0.5°
Vertical Alignment of the V-Grooved Pulleys
The alignment of the V-grooved pulleys is checked before and after tightening
the taper bushes with an alignment rail.
Note!
Check whether the face widths of the V-grooved pulleys have the same sizes.
A possible deviation of the face width has to be taken into account. With a
symmetrical face set-up, the distance of the parallel, to the smaller face is half
the deviation.

Always install the V-belts without force. Installations using screw drivers,
crowbars etc. cause external and internal damage to the belt. V-belts installed
under force might only run for several days. A proper installation of the belt
saves time and money.
If the installation space is too small, the V-grooved pulleys with belts should be
slid onto the shafts.
BelT TensiOn
use belt tensioning values according to Optibelt recommendations. Set the belt
tension with parallel motor and machine shafts. Operate the belt for some
rotations and check the belt tension again. In our experience, belt tension
should be checked again after an operating time of about 0.5 to 4 hours and
then be corrected, if necessary.
For further information about belt tensioning see page 151/152.

allOWeD shaFT DeViaTiOn
After applying the initial installation tension,
the distances X1, X2 between the two pulleys
dd1, dd2 and the alignment rail on axis level
should be measured, alternatively with the
optibelt LASEr POInTEr. The maximum
allowed values for the distance X from the
table should not be exceeded, depending
on the diameter dd. Depending on the pulley
diameter, the intermediate values for X
should be interpolated.

We recommend checking the drive regularly, e.g. after each 3 to 6 months.
V-grooved pulleys are to be checked for wear and consistency. use the
Optibelt profile and V-groove gauge tools.
When changing V-grooved pulleys with taper bushes (see fig. on page 160)
the following aspects have to be observed:
1. Loosen all screws. unscrew out one or two screws depending on the bush size, grease them and
screw them into the set bores.
2. Tighten the screw or screws equally until the bush releases from the hub and the pulley can be
moved freely on the shaft.
3. remove the pulley with the bush from the shaft.

Storage
•General note
Properly stored V-belts retain their properties for many
years (see also DIN 7716). However, when stored under
adverse conditions or handled incorrectly, the physical
properties of most rubber products will be impaired. This
can be the consequence for example of the effects of
oxygen, ozone, extreme temperatures, light, moisture or
solvents.
•Storage area
The storage area should be dry and dust-free. V-belts must
not be stored close to chemicals, solvents, fuels, lubricants
and acids etc.
•Temperature
V-belts should be stored at temperatures between +15 °C
and +25 °C. Lower temperatures usually have no negative
effect on the V-belts. However, since belts become very
stiff at low temperatures, they should be warmed to
approximately +20 °C before installation to avoid
breaking and cracking.
Radiators and supply pipes should be screened. V-belts
should be stored at least 1 m away from heat sources.
•Light
V-belts should be protected against light, especially direct
sunlight and strong artificial light with high ultra-violet
radiation (ozone formation) such as naked fluorescent
tubes. Illumination using appropriate lamps is recom
mended.
•Moisture
Damp storage areas are unsuitable. Care must be taken
to ensure that condensation does not develop. The most
favourable relative air humidity is below 65 %.
•Proper storage
Because stress can promote both permanent deformation
and cracking, care must be taken to ensure that V-belts
are stored without stress i.e. without tension, compression
or any other form of pressure.
If V-belts have to be stored horizontally and stacked on
top of each other, it is recommended that the stack height
does not exceed 300 mm in order to avoid permanent
deformation. If, in order to save space, V-belts are hung,
the diameter of the cylinder on which the belts rest should
be at least ten times the height of the belt profile.
optibelt S=C Plus, optibelt SUPER E-POWER M=S,
optibelt SUPER X-POWER M=S and optibelt
SUPER TX M=S belts do not need to be stored in
sets as they can be used in sets without measuring.
•Cleaning
Dirty V-belts can be cleaned using a 1:10 mixture of
glycerine and methyl spirits or with brake cleaner. Petrol,
benzene, turpentine and the like should not be used. In
addition, sharp objects, wire brushes, emery paper etc.
must be avoided under all circumstances, as these can
cause damage to the belt.
•Ozone
In order to counteract the harmful effects of ozone,
storages should not contain any appliances that generate
ozone, e.g. fluorescent lights, mercury vapour lamps or
high voltage electrical equipment. Combustion gases and
vapours which could lead to the formation of ozone by
photo-chemical processes must be avoided or eliminated.

Belt length measurement
The belt is placed over two identically sized measuring
pulleys of the groove design shown in the following drawings. The dimensions are given in the tables 85 to 91 on
pages 169/170.
Measuring pulley for wedge belts DIN 7753 part 1 and
classic V-belts DIN 2215
By moving to the adjustable pulley the force Q is applied on
the belt. Before measuring the drive centre distance a, the
belt should be rotated three times under load. This ensures
that the belt is well seated in the pulley, an essential
pre-condition for the accuracy of the resulting measurement.
The length is obtained by adding the diameter of the pulley
to twice the drive centre distance a.

PrODucT DescriPTiOn
Optibelt has developed a series of conveyor elements for
the economical conveyance of goods in a varied range of
applications.
horizontally, or inclined up or down. Vertical conveying is
also possible if the belts are arranged top surface to top
surface, gripping the goods between them.

construction/quality
Optibelt conveyor elements consist of the basic belt and the
top surface. These parts are specially connected via vulcanisation. The variety of applications required constructions
with numerous patterns available in different qualities. Both
pattern and surface quality should be adapted to the
individual application.

For the conveyance of:
• doors, cupboard parts, veneer and plastic panels in the
woodworking industry
• body parts and sharp-edged sheet metal in the automotive
industry
• cardboard and boxes in the packaging industry
• roof tiles, concrete slabs and block paving stones
• tiles
• flat glass
• postal items
• bowling balls on bowling lanes
In addition to the conveyance options, these belts are also
used for
• labelling and sealing of tins and jars in the canning
industry
• lifting, chopping and sorting of beet, potatoes, salad, cauliflower, Brussels sprouts and other vegetables in the
agricultural industry
Due to their single belt characteristics and high surface
load, optibelt KB kraftbands with patterned top surfaces are
especially suitable in conveyor systems and lifting platforms
for:
• the conveyance of cargo containers
• loading and clearing of airplanes and railway wagons
• stowing and unloading of ship cargos

Properties
Special surfaced belts are used instead of expensive
conventional type conveyor belts. They run individually, or
in sets arranged adjacent to each other, transporting goods

cOnVeYOr eleMenTs
Design guiDelines
Drive and guide pulleys
The drive and guide pulleys should be V-grooved pulleys.
The minimum diameters should be selected according to the
standard recommendations for V-belts and kraftbands. See
the chapter on V-grooved pulleys.
Due to the relatively low transporting speed (experience has
shown that it is usually less than 1m/s) and the resulting low
flex rate, pulley diameters can be reduced to approximately
10 % below the recommended minimum. With greater
reduction, there is danger that the top surface separates
from the V-belt base.
The driver pulley should be arranged at the discharge end
of the conveyor so that the goods are pulled along.
The diameter and the number of support idlers required
depend on the length of the conveying span and the weight
and size of the goods to be conveyed.
Supporting tracks, generally made of plastic, are either flat
or with a key seat to improve guidance of the conveyor belt.
As with the support idlers, the grooves must have an
adequate width.
adjustment of the drive centre distance allowances
The tables on pages 82 to 84 show the drive centre distance allowances for special purpose conveyor belts and
kraftbands.
Tensioning options
An adequate belt tension is essential to
the reliable operation of the conveyor
system. Tension is applied by adjusting
the drive centre distance or, when the
centres are fixed, by tension idlers.
support idlers/tracks
In most cases, support idlers or tracks are
required to prevent the belt from sagging under
load.
Support idlers may be flat faced or V-grooved
pulleys. The dimensions of the pulley grooves
should support the base of the conveyor belt in
the base of the groove so only one edge can run
on the groove flank, and thus cannot get stuck in
the groove.
When idlers are employed, they should
be arranged inside the belt if possible,
as otherwise the alternating flexing of
the belt will reduce its service life.
