INSTALLATION GUIDE
Torque Team ® V-Belt
TENSION
Proper tension is essential for maximum belt life and effciency.
Improper belt tension is the primary cause of premature belt
failure and increased costs. Under-tensioned belts lead to
slippage, overheating, and noise, all of which lead to higher
maintenance costs and ineffcient transmission of power. Also,
over-tensioning belts leads to premature wear, along with
bearing, shaft, and sheave problems. The result is more frequent
replacement of drive components and costly downtime.
Common Sense Rules of Torque Team® Belt
Tensioning
The ideal tension is the lowest tension at which the belt will not slip
under peak load conditions.
Check the belt tension frequently during the frst 24-48 hours of
run-in operation.
Do not over-tension belts. Doing so will shorten belt and bearing life.
Keep belts free from foreign materials that may cause slippage.
Inspect the Torque Team ® drive periodically. Re-tension the belts if
they are slipping.
Maintain sheave alignment with a strong straight-edge tool while
tensioning Torque Team® belts.
Tensioning Methods
When you install belts at optimal tension, you save time and
money. To illustrate this point, the fgure below compares the cost
and accuracy of various V-belt drive tensioning methods.
Choose one of four tensioning methods for V-belts:
TensionRite®
Two TensionRite® gauges are available: one for single belt drives
and another for banded belt drives.
For more detailed instructions for using TensionRite,® refer to the
instructions attached to gauge.
The gauge defects the center of the belt span and the force of this
defection is compared to a target defection force for the particular
span. Then, one can adjust the belt tension until the actual
defection force equals the target.

TensionRite® Belt Frequency Meter
Using advanced optical technology, our TensionRite® Belt
Frequency Meter provides a simple, repeatable and reliable
method for tensioning belts. It displays the natural vibration
frequency of the belt strand so you can closely monitor belt
tension. The device works with all industrial transmission belts
including V-belts, synchronous belts, banded belts and Poly-V®
belts and calculates the corresponding belt tension in either
English or SI units.
Defection Principle
Plunger-type gauges utilize the defection principle to check the
tension of a belt drive.
