Cam clutchs are precision devices which lock the inner and outer races through the wedding action of cam to transmit torque in one direction of rotation, and overrun in the opposition. These units are often referred to as free wheels, sprags and overrunning, Backstop or one-way clutch depending upon their application.         MG MI MR Series           MG Series clutches are used for high-speed inner race overrunning.
