Torque limiters free rotation

Torque limiters free rotation

A backlash free safety coupling with free rotati on and no residual torque suitable for high speed transmission. The disengagement is
instantaneous once the torque is reached, the calibration is adjusted by changing the pressure of the springs. The re-engagement is manual, quick and reliable.

  • Protect the elements of a transmission even in case of high inertias
  • Protect the product from shock or incorrect positioning
  • Protect devices during transmission at high speeds of rotation
  • Greater durability of all devices, thanks to the free rotation

On request

  • Complete transmission gear worked and fitted (crown, pulley, gear, …)
  • Can be supplied with various type of rigid/elastic couplings for in-line shafts transmission
  • Possibility of surface treatments for corrosion-specific needs
  • Version with the attacks of the 8-hole competition


Short info

  • Absence of torsional play during the transmission of motion
  • Fine-tuning the torque through a balanced radial ring
  • Motion transmission through balls
  • An innovative calibration system for an immediate calibration of the equipment
  • Manual re-engagement
  • No residual torque after disengagement
  • Possibility of combining a switch / proximity to stop the engine

Main Applications

  • Extruder
  • Packing machines
  • Automation technology
  • Test benches
