Model TB - Spring & Detent Clutches

 

The Model TB "Through Bore" Torque Limiters are designed to have the motor shaft, gearbox shaft, or a jack shaft project straight through the entire clutch to provide bearing support for the output drive. They are available with a plain shaft for your coupling, pulley, gear or sprocket or built ready to run with your specified drive as an integral component designed into the clutch at the factory. When a jam or overload occurs, the output shaft will slip or stop. They reset automatically, make clicking alarm noise, and are adjustable via the threaded housing to increase or decrease the "break-away" torque threshold. They protect expensive machinery and minimize downtime.
