Trapezoidal lead nuts GN 103.1 are used together with trapezoidal lead screws GN 103. They can be fastened to the component to be adjusted via the bores in the flange. The centering step d2 is used to position the nut.
The trapezoidal lead nuts should be lubricated to minimize wear. However, if lubrication is insufficient, the bronze alloy (gunmetal) generally has emergency running properties.
