A belt’s purpose is to transmit energy between two components. The number one cause of a power transmission belt failure is improper tensioning.
The correct belt tension is a critical step when installing and maintaining a belt. Not enough tension results in slippage, excess heat, premature belt and pulley wear. Excessive tension results in stress on belts, bearings, and shafts. There is still a tension range which a belt will operate satisfactorily.
- Too little tension results in slippage, excess heat, and premature belt & pulley wear
- Too much tension results in excessive stress on belts, bearings, and shafts
