Stieber Clutch Self-Contained Freewheels RDBR-E

Backstops type RDBR-E are directly mounted on the drive shaft, e.g., heavy-duty conveyer belts, mixing drum drives, and chain conveyors, when torque limiting/load sharing or the release function is required.

RDBR-E features a roller-type backstop design with a fully bearing supported multidisc brake for the torque limiting function. The optional release function allows the tension of a jammed belt to be controlled and released. Once the brake is fully opened, the capability of unlimited rolling backward makes maintenance safe and easy.

To activate the release function, a simple hydraulic hand pump or power pack can be used. A mechanical release is available on request. Backstop RDBR-E is self-contained and oil lubricated.

A special sealing arrangement with grease packed labyrinth seal guarantees the highest reliability under harsh conditions. The recommended shaft fit is H7/f6. The torque arm must not be rigidly fixed to the foundation. For security reasons, a stopper in overrunning direction is recommended. When installed, the backstop must be axially secured.
