The Model SXT " Shaft Extension" Torque Limiters are designed to mount on the standard length shaft of motors and reducers and provide complete bearing support for overhung or sideload of chain or belt drives. 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.
