R+W couplings torque limiters

Reliable torque overload protection. The usage of ST model Torque Limiters minimizes machine downtimes as a result of a crash and ensures the availability and productivity of your machine. ST Torque Limiters are designed for high torque capacities which are achieved by strong modules evenly spread on the circumference.

The R+W torque limiter model ST is based on a spring loaded
form fit design. The transmittable torque is determined by the number of modules that are evenly spread on the circumference and their bolt circle diameters.

In the event of a torque overload the balls jump out of the detents in axial direction resulting in a permanent separation of the drive and driven elements. An axial force on the plunger re-engages the module.

Dust and dirt penetration is prevented by the sealed torque limiter design.
