Type AQ4.0 Ball Torque Limiter

Product Features

Torque limiter protects rotating machines and components from damage by sliding when the torque excesses the pre-set value in sudden loading, over-loading or power off. When a torque overload occurs, the balls or rollers overcome the spring pressure and force the drive and driven element apart. The balls or rollers then slide out of the sockets. This disconnects the driving and driven elements from each other so they rotate relative to each other in tracks around the plates.

Advantages

Torque Limiters are automatic safety devices to prevent overload, providing reliable operations and adjustable functions

Torque limiter with high power density due to high-quality materials

High density linings for long life

Zinc-coated and yellow passivate

Easy setting of slipping torque with usual tools
