DM Series

DM series direct mounting sprag clutches are specifically designed for use as backstops in applications where compact dimensions are required.

The clutch is designed to fit in a housing with the shaft as the inner race. This type is particularly suitable for use in gear units and similar equipment where good concentricity between shaft and housing is ensured.


  • High torque capacity yet compact direct mounting design
  • Suitable for backstopping applications
  • DM clutches drive directly onto the shaft, without an inner race, resulting in compact design.
  • The clutch is suitable for use in gear units where the oil provides lubrication
