Cam clutch, MG series, 1 keyway, open, 50 mm bore, 3140 Nm, Tsubaki.

Cam Clutch products are designed to transmit torque in one direction of rotation, and overrun (freewheel) in the opposite direction of rotation. In backstop applications, the clutches are used to prevent reverse rotation of drive shafts, which may cause damage to machinery and other expensive equipment. With the outer race of the clutch anchored stationary, the inner race can overrun freely in one direction of rotation. Reverse rotation is instantaneously prevented by the automatic engagement of the clutch. MG Series clutch is used for low to medium speed inner race overrunning.
