Friction torque limiter coupling is also called safety clutch coupling. The friction torque limiter coupling is often used to install between the principal and passive side power transmission, when overload fault happened more than set value (torque) and the torque limiter will produce separation, thus effectively protect the drive machinery, such as motor, reducer, servo motor) as well as the load, common form as follows: Friction torque limiter coupling and ball type torque limiter.

The mounting structure of torque limiter is shaft-shaft, shaft-flange, shaft-synchronous pulley, shaft-sprocket, shaft-gear, shaft-pulley and so on.

The friction torque limiter coupling are used in printing equipment; battery industry, iron scrap conveyor, conveying production line, divider.
