Tsubaki of Canada Limited - CA Series Cam Clutch

The CA Product Line of backstops are an integral part of the reducer. The unique non-roll over cam design is key for the prevention of reverse rotation in the reducer. This feature prevents damage to the gears, shafts and drive train. This extends the life of the reducer and assures proper performance.

Note: Do not use Extreme Pressure (EP) lubricants on reducers with backstops as this will alter backstop performance.
