Safety Couplings

Our range of direct-drive and indirect torque-limiting safety couplings disengage highly dynamic drives within an unprecedented 2-4 ms of an overload signal, and then automatically re-engage at the precise angular position. To date, no other overload protection equipment responds as quickly without elaborate monitoring systems. Conventional couplings typically take a full second to disengage.

Rimtec safety couplings are designed with integral precision roll or ball guides, which guarantee a totally backlash-free transmission of torque in both directions of rotation and under high acceleration. The couplings are uniquely designed with a pre-stressed, degressive Belleville spring that generates extremely fast switching times, and protects equipment from even ultra-short surges in speed.

Benefits/features include:
- Zero backlash operation
- Exact transmission of the rotational movement
- High stiffness and low inertia
- Low residual friction after disengagement
- Smooth operation
- Safety feature: emits a signal when overload occurs
- Reliability, precision, power and repeatability all in one package
- No wear, maintenance-free; built to last
- Meets machine manufacturing standards for automated production and assembly machine
