Product Features
Usage Method
■ Simple Steps for Selecting Round Belts
(1) Determine the transmission power (or motor rated power)
(2) Confirm the diameter of the small pulley
(3) Calculate the tension borne by the belt
(4) Select a belt with allowable tension greater than the tension calculated in step (3)
(5) Finalize the belt selection
For details, please refer to
