GN 5910 Torque Limiting Knurled Knobs with Adjustable Torque


GN 5910 Torque Limiting Knurled Knobs, with Adjustable Torque
ELESA original design
code: MZD-A / -p

Product description


Torque limiting knurled knobs GN 5910 are used when the manually applied torque is to be limited. The torque limit can be set between 0.2 Nm and 1 Nm.

When turned clockwise, the torque mechanical system of the knurled knob triggers an „over-engagement“ as soon as the specified torque is reached. When tightening, this will ensure that the maximum permissible torque is not exceeded. When turned counterclockwise, the mechanism locks such that the torque necessary for releasing is transferred.

Endurance tests have shown that the torque does not change even after up to 60,000 tightening cycles.

Adjustment of the torque

To adjust the torque, the cap of the torque limiting knob is removed to access the adjustment mechanism and to disengage the locking of the torque setting.

Einstellung Drehmoment GN 5910

The torque is set with the hexagon socket bolt in the center of the knob. The graduated dial moves in the axial direction, increasing or decreasing the torque limit.

Einstellung Drehmoment 2 GN 5910

The set torque value is indicated on the graduated dial. Depending on the torque value, the slanted surfaces of the indicator window are level with the graduation marks of the graduated dial. After setting the torque, the cap must be reattached. This locks the torque setting and protects the adjusting mechanism from unauthorized access.
