The set screw in GN 437 hinges allows the mobility of the hinge to be changed, and also generates a constant braking torque adjustable across the entire rotating range. The rotation of doors and flaps is inhibited, preventing inadvertent movement.
The friction torque is accomplished by interlocking two slim friction cones. The large friction surface and the hard-wearing plastic of the friction cones guarantee a long service life with virtually constant stiffness.
Owing to the structure and the pre-stress of the friction cones, the hinge has virtually no radial play and no play at all in the axial direction.
Friction cone is temperature resistant to 80° C (176° F)
*Various metric and inch size fasteners and kit packaging available upon request.
