Long‑Life Sprag One‑Way Transmission Clutch

This Backstop from Hebei Fenna Transmission Machinery Co.,Ltd is non‑contact sprag‑type one‑way clutch. It keeps non‑contact status during forward overrunning to greatly reduce friction, heat generation and component wear. The sprags engage instantly to lock and prevent reverse rotation under reverse torque. Without built‑in bearings, it needs matched bearings to ensure coaxiality of inner and outer rings. It features great high‑speed adaptability, stable locking performance and long service life, widely used for anti‑reverse protection and two‑speed switching for conveyors, elevators and various high‑speed transmission equipment. This Backstop can work with Driving Drum, and cooperate with Serpentine Spring Coupling and Roller Chain Coupling to build complete transmission systems. Locking Assemblies or single Locking Assembly are available for shaft‑end locking without keyway processing, fitting multiple shaft sizes for easy on‑site installation and adjustment.
