R and W Torque Limiters

The use of a reliable R+W Torque Limiter will isolate the driving from the driven elements within a matter of milliseconds, once the torque reaches a preset overload value. Incorporating R+W torque limiting couplings into modern machine design will help insure high productivity and higher profits.
Features & Benefits:
- Every torque limiter type available in 4 versions
- Single-position re-engagement: re-engages after precisely 360° (Standard version)
- Multi-position re-engagement: re-engages every 60° (standard), 30°, 45°, 90°, or 120°
- Load holding: holds the load until automatic re-engagement
- Full disengagement: disengages with no residual friction, stays disengaged until manually re-engaged (60° angular intervals)
- Provides signal upon overload
- Maintenance-free
- Zero backlash
- Stainless steel and other corrosion proofing optional
- Keyway available for all models
- Optional sealed versions available for SK models
