HomeProductsTorque limitersTorque limiter free rotation

A backlash-free safety coupling featuring free rotation and low residual torque, designed for high-speed transmission. Disengagement is instantaneous upon reaching the set torque; the torque setting is adjusted by altering spring compression. Re-engagement is manual, quick, and reliable.

  • Zero torsional backlash during motion transmission;
  • Fine torque adjustment via a balanced radial ring;
  • Ball-bearing transmission mechanism;
  • Innovative setting system using the “H” dimension for immediate device calibration;
  • Manual synchronous re-engagement (1 position per 360° revolution);
  • No residual torque after disengagement;
  • Designed for integration with a microswitch or proximity sensor to stop the drive.
  • Supplied complete with machined and assembled transmission elements (plate wheel, pulley, gear, etc.);
  • Available with various types of rigid or elastic couplings for in-line shaft transmission;
  • Corrosion-resistant surface treatments available;
  • Available with an 8-hole mounting pattern interchangeable with major competitors.
  • Extruders;
  • Packaging machines;
  • Automation technology;
  • Test benches.
  • Protects transmission components even in case of high inertia;
  • Protects the product from shock or incorrect positioning;
  • Protects mechanical devices during high-speed rotation;
  • Extended component life thanks to the free rotation feature.
