One-Way Clutch Bearings

Product Description

Drawn cup roller clutches are one-way clutches comprising thin-walled, drawn outer rings with a series of ramps on the inside diameter, plastic cages, springs and needle rollers. They can transmit torques in one direction and are radially compact. The roller clutches are available with and without a bearing assembly.

Drawn cup roller clutches give very precise indexing, since individual spring retention of each needle roller ensures constant contact between the shaft, needle rollers and the clamping surfaces. They allow high indexing frequencies due to their low mass and therefore the low moment of inertia of the clamping elements. They also have a low free-wheeling frictional torque.
Drawn cup roller clutches can be used in a wide variety of applications, for example as indexing elements, back-stopping clutches or overrunning clutches. The drawn cup roller clutch fulfils the overrunning or holding function as appropriate.

Design Attributes:
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.

Applications:
Paper moving (copiers, fax machines, paper towel dispensers, etc. )
Exercise equipment
Appliances
Two-speed gearboxes
Rack indexing drives.
