Torque limiters

The new R+W ST model torque limiters are designed to minimise machine downtime as a result of a crash.

Designed for high torque capacities, the torque limiter 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.

Areas of application include excavators, rolling mills, dredgers, steel mills and large lifting devices.
