Additional Information

OP series slip clutches are designed for transmissions utilizing precision "O" ring belts and requiring precise overload protection as in tape drives and other similar drives.

OP Series Slip Clutches are designed for long life under continuous slip conditions. The useful life of these elements is a function of the transmitted torque and slip speed. Service life expectancy is 1 - 2 million slip revolutions, increasing to 5 - 10 million slip revolutions if heat treated.

  • 1 Stock units are calibrated with equal CW and CCW slip torques corresponding to the tabulated Upper Limit Torques. Other torques are readily available from full, down to 1/8 of the Upper Limit Torque for each model.
