Martin TT35BS 7/8 torque limiter overload clutch with 7/8" finished bore, keyway, and setscrews. Bored-to-size sprocket-style hub protects machinery from torque overloads in power transmission applications.

Starting shock from electric motors is a major cause of maintenance of moving parts. Torque-Limiter clutches provide a cushion by slipping until the torque drops to a pre-set level. They can be set to reduce shock loads on motors and driven equipment during reversing or inching. They provide mechanical protection against breakage due to sudden overload — by slipping when the pre-set torque limit is reached. Martin can provide many tooth counts that are not listed by quickly altering stock sprockets.
