FU-PR Balls Torque Limiter For Gearboxes

FU-PR Balls Torque Limiter For Gearboxes  is a safety coupling to be mounted between the motor and gear unit thus reducing significantly the size of the device at the same power output.

Torque max 2600 Nm – Max bore ø55 mm.

  • Safety coupling made in steel fully turned, spacer made in aluminium fully turned for IEC-B5 motors
  • Standard treatment of phosphating on torque limiter.
  • Compact solution.
  • Model available for IEC motors and gearboxes.
  • Protection in both directions.
  • Instant disengagement upon overload.
  • Fast and simple calibration using our “H” dimension procedure.



  • Conveyor.
  • Packaging machines.
  • Wrapping machines.
  • Motorized systems of handling and positioning.


  • Simplicity and sensitivity compared to gearbox integrated solutions.
  • Protect the motor-gearbox from accidental collisions or impacts from the products being processed.
  • Greatly reduces production downtime in case of overload.
  • Absorb static torques without disengaging (friction model).
