Drawn cup roller clutches are designed to transmit torque between the shaft and housing in one direction and allow free overrun in the opposite direction. These designs utilize the same small radial section as drawn cup needle roller bearings. The units are compact, lightweight and operate directly on a hardened shaft. Proper mounting is easily accomplished with a simple press fit in the housing. Clutches and clutch and bearing assemblies are offered both in inch and metric nominal series.
Size range: 4mm - 30mm (1/8 in. - 1 in.) bore
- When transmitting torque, either the shaft or the housing can be the input member.
- Rollers wedge against precisely formed interior ramps to positively transmit torque.
- Transition from overrun to lock normally occurs with the minimal lost motion (backlash)
- Drawn cup roller clutches are offered as clutch-only unit or as a clutch and bearing assembly.
- Clutch-only units should be used with external radial support to hold the shaft and housing concentrically and carry radial loads.
- Paper moving (copiers, fax machines, paper towel dispensers, etc.)
- Exercise equipment
- Two-speed gearboxes
- Rack indexing drives
