Freewheels — Clutch acting in one direction of rotation only

Freewheels transmit a torque in only one direction. In one direction of rotation the inner ring can rotate freely against the outer ring, in the other direction the two rings are firmly blocked against each other. The freewheels can be used as backstops, overrunning clutches or indexing freewheels.

Ball Bearing Freewheels

Enable torque transmission in one direction, in the other direction of rotation there is no connection between the inner and outer rings. Can be used as backstops, overrunning clutches or indexing freewheels.

Bearing Supported Self Contained Freewheels

The sprag freewheels are centered by plain bearings. It is suitable for low speeds. Is mainly used as backstop.

Drawn Cup Roller Clutches

One-way clutches consisting of an outer ring with clamping ramps, a plastic cage, individual pressure springs and needle rollers. They are space-saving radially and enable high switching frequencies.
