Size Range
Inch: 1/8 in. - 1 in. bore
Metric: 4mm - 30mm bore
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. When transmitting torque, either the shaft or the housing can be the input member. Precisely formed interior ramps provide surfaces against which the rollers wedge to positively transmit torque. Transition from overrun to lock normally occurs with minimal lost motion (backlash). Drawn cup roller clutches are offered as a 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.
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.
