Backlash free Safety coupling suitable for high speeds, with free rotation and low residual torque after disengagement that occurs in a precisely and immediately. The re-engagement is manual.
Safety coupling with simple and compact balls inserted directly in the drive element of transmission. The disengagement occurs quickly and safely if the calibrated torque is exceeded.
Sliding Safety coupling where the transmission component is fitted between two friction rings and slides when the calibrated torque is reached. The minimum required to have a low cost protection.
