Additional Information

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

All clutches in this series have a pilot diameter "K", and three tapped holes "N" for mounting a gear, sprocket or pulley on the input hub. Screw penetration into the clutch housing must not exceed the depth specified in column "N".

Input gears, sprockets or pulleys are available as optional items or can be "designed-in" as integral assemblies. Standard "PB" and "CX" Series clutches with integral 1/5" gearbelt pulleys are also available.

  • 1 Stock units are calibrated with equal cw and ccw slip torques corresponding to the tabulated Upper Limit Torques. Other torques are readily availabe from full, down to 1/8 of the upper limit torque for each model. Torque values are independent of each other for cw and ccw rotation, and may be specified the same or different for the two directions.
