Backstop Cam Clutch

In backstopping applications, clutches are used to prevent reverse rotation of drive shafts which may cause damage to machinery and expensive equipment.  The inner race can overrun freely in one direction of rotation.  Reverse rotation is instantaneously prevented by the automatic engagement of the clutch.  Typical backstop applications are in conveyor systems and gear reducers.  Tsubaki has pioneered the non-rollover design.
