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 a 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.|1/2" Shaft Extension Clutch with 12L075 timing belt pulley output set to transmit up to 20 inch pounds torque and re-engage every 72 degrees.
