Coil spring torque limiter

What is structure of coil spring torque limiter?

A coil spring is press-fitted in the sleeve, and when it turns, it slides and generates torque. The more it tightens a coil spring, the more it generates torque, but the more loosen coil springs, the lower it generates torque.

Advantages of using a coil spring torque limiter compared with a magnet torque limiter!

1. Light Weight

2. Compact Size

3. Competitive Price
