Renold SH Series Sprag Clutch Holdbacks

Sprag clutch holdbacks with central torque arms are designed as self-contained units that can be easily mounted on the head shafts or other driving shafts of inclined conveyors or elevators.

Reverse rotation or runback in conveyors can lead to serious safety issues and potential machinery failure. To address this problem, Renold Sprag Clutch holdbacks are commonly used. They are specifically engineered to prevent the rotation of the conveyor head shaft. It is mounted on the head shaft and secured with a torque arm that is positioned against stops fitted to the framework of the conveyor. This configuration ensures that the holdback unit remains in place and can effectively engage when needed.

Their unique design allows them to be widely used in the Mining Industry and Material Handling for inclined belt conveyors and bucket elevators.
