Torque limiter is a protective device that limiters the torque transmitted in a drive system by slipping when torque demand. 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
