Balls torque limiters

Balls torque limiters

Safety coupling with the transmission of motion by means of hardened balls inserted directly in the drive element, obtaining a simple, compact and competitive device. The disengagement occurs quickly and safely allowing the stop of the transmission if the calibrated torque is exceeded.

  • Protects the product from damage or wrong positioning
  • Protect the gear motor from accidental product collisions
  • Protect the drive against bumps or limit
  • Protects conveyor belts in case of product collisions
