Modular torque limiters

Modular torque limiters

Modular safety coupling, robust, suitable for “heavy industries” even at high speeds. After disconnection there is free rotation without residual torque, re-engagement is simple and manual.

  • Product protection in case of overload
  • Protection of operating units of machines in case of a collision
  • Protection of the drive from external overloads
  • Protecting conveyor belt stoppages

On request

  • Overload signal ring
  • Possibility of fitting with finished bore and keyway or locking assembly
  • Possibility of surface anticorrosive treatments for specific requirements


Short info

  • Made in steel fully turned, with high mechanical strength
  • Free rotation after disengagement without residual torque
  • Reliable and maintenance free
  • Protected from external agents
  • Suitable for high rotation speeds and high inertias
  • Simple system of calibraton and re-engagement
  • Compact and robust design

Main applications

  • Extruders and mills
  • Mining industry and transporters
  • Heavy industry
  • Earthmoving machines and shredding/crushing machines
