Mechanical Clutches

Discover a wide array of shaft couplings, chains and sprockets, belts and sheaves, and drive components.
Mechanical clutches control power delivery between two rotating shafts in high-torque, high-speed applications. The clutch connects and disconnects power flow from the shaft attached to the motor and the shaft attached to the power output device. They come in a variety of types such as centrifugal, wrap spring, and ramp and roller. Each type is ideal for different applications, which can include backstopping, overrunning, and indexing.
