Definition Torque Limiter ( Safety Couplings )
Torque Limiter are used to protect machines ( Safety Couplings ), equipments and people against damages. The drive is disconnected, when the torque is higher than the disengagement torque of the coupling.

Application of Torque Limiter ( Safety Couplings )
With increasing automation of production lines those components are gaining rising importance, which in case of overload protect machines from damages or iniate automatical shut off. The performance rates e.g. of servo drives especially in NC-machine tools are raised from year to year. Combined with it the rapid traverse rates increase. At these high-speed movements in the machine, a collision results in severe machine damage and expensive outage time. Safety Couplings are used to protect against these damages or at least to reduce them. Torque Limiter can be used everywhere in such equipment where torque limitation is necessary in order to protect machinery or products against overloading.

Definition shaft couplings

Shaft couplings are compensating couplings with a backlash free and conformal torque transfer providing high torsional stiffness and a low moment of inertia. According to these requirements, our metal bellow couplings can be regarded as the ideal solution. For more than 25 years, they have proven themselves in thousands of servo drives as being excellent.
