FU-DSS/SG Balls Torque Limiter Free Rotation

A backlash free Safety coupling with free rotation and low 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. High sensitivity in the negative version.

Maximum torque: 1200 Nm – Maximum bore ∅60mm.
