FU-EDF/F Economic Ball Torque Limiter

FU-EDF/F Economic Ball Torque Limiter is a 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. Can be tailor-made to client’s needs. The disengagement occurs quickly and safely allowing the stop of the transmission if the calibrated torque is exceeded.The calibration is adjusted by changing the pressure of the springs.

  • Reduced torsional backlash by ball drive.
  • Maintenance free for long lasting, high reliability.
  • Version with 360° phase re-engagement available.
  • Model available only with plate wheel or other transmission component.
  • Innovati ve calibration system by “H dimension“ for an immediate calibration of the device.
  • Possibility of combining a microswitch / proximity to stop the drive.
  • Suitable for use in damp and oily environments.
  • Model with flange for custom links: EDF / F / F.

Maximum torque: 1450 Nm –Maximum internal bore: ∅55mm.
