A high-precision ball safety coupling providing backlash-free motion transmission with high reaction sensitivity and immediate release without torque spikes. Torque setting is adjustable via spring compression. The transmission component is supported directly by a ball bearing within the device.

  • Exact torque regulation via a balanced radial nut;
  • Innovative calibration system using the “H” dimension for immediate device setup;
  • Equidistant (multi-position) or 360° synchronous re-engagement (DSS/F/SG);
  • Maintenance-free;
  • Compatible with microswitches or proximity sensors to stop the motor drive;
  • Model available only with finished bore.
  • Supplied complete with machined and assembled transmission elements (plate wheel, pulley, gear, etc.);
  • Available in stainless steel for food and pharmaceutical environment;
  • Connection flanges available for most common indexing tables/drives;
  • Customized phase re-engagement angles available (30°, 45°, 60°, 90°, etc.)
  • Printing and packaging machinery;
  • CNC machine tools;
  • Indexing tables, filling machines, and linear guides;
  • Servomotors and slide guides.
  • Protects the product against incorrect positioning on rotary tables;
  • Protects indexing mechanisms against overload;
  • Protects machine tool operating units against impacts;
  • Protects slides or servomotors against collisions with mechanical stops.
