Torque limiter free rotation
Up to 1,300 Nm of torque and 65 mm bore diameter.
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.
