Mechanical Clutches







Cam clutches are precision devices that lock the inner and outer races through the wedging action of cams to transmit torque in one direction of rotation while overrunning in the opposite direction of rotation. These units are often referred to as freewheels, sprag, overrunning, backstop or one-way clutches, depending upon their application.

Clutches are available with a bore range up through 17.7” and a torque range up through 720,000 lb. ft. and are the most complete and versatile cam clutches available for a variety of applications – from small business machines to giant steel slitters.

Ten series of clutches perform three basic modes of operation:

  • Overrunning
  • Indexing
  • Backstopping

These units have set standards of performance, offering:

  • Higher overrunning speeds
  • Greater torque capacities
  • Longer service life
