Safety Couplings - Adjusting the disengagement torque
The disengagement torque is generally between approximately 40% and 100% of the nominal torque of the
coupling and is easily adjustable. If the customer does not specify a disengagement torque value, it is set at the maximum torque (nominal torque) of the safety coupling. The disengagement torque can be adjusted
(on the machine) if necessary at a later date by turning the adjusting nut with a pin wrench. Adjusting nuts are
provided with a user friendly scale; the disengagement torque, and the reference marks for Tmin and Tmax, are
engraved on the face side of the adjusting nut to facilitate setting. Greater disengagement torques greater than
Tmax are possible (on request); though this results a stronger wear of the disengagement mechanism.
Due to the degressive spring characteristic within the torque setting range, a counter clockwise turn of the adjusting nut means an increase, while a clockwise direction turn means a reduction of the disengagement torque (See direction arrow at clamping nut)!

Loosen and remove the retaining screw (see detail Z) completely. Turn the adjustment nut with pin wrench. After adjusting, re-secure the adjustment nut by drilling and tightening the self-tapping screw.
GAM Safety Coupling Series: SKB / SKX-L
Release retaining screw and turn adjusting nut with pin wrench (note reference mark). Tighten retaining screw on hub after setting the required disengagement torque. Setting can be done by turning the hub with scale until the torque value to be set is in line with the reference mark. In mounted status the clamping screw must be released and after setting the disengagement
