R+W = reliable torque overload protection


Using ST model Torque Limiters minimises machine downtime 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.

These torque limiters can be used for excavators, rolling mills, dredgers, steel mills,
turbine construction and large lifting devices.
