One way clutch bearings (also known as sprag clutch) are compact, lightweight and operate directly on a shaft. One way bearings are used to transmit high torque between the shaft and housing in one direction and enable free motion in the opposite direction. The torque is transmitted by rollers that wedge against interior ramps.

We supply one way bearings with or without internal or external keyways. Inside diameters starting from 8mm to 40mm, with outside diameters ranging from 22mm to 80mm. 

Sprag clutch bearings are available as clutch-only or as a clutch and bearing assembly. Benefits include:

  • High torque
  • High rotational speed
  • Easy to mount
  • Require little maintenance
  • Operating temperature between -40°C and 100°C
