GN 638 Ball Jointed Leveling Feet Thrust Pad NBR, Threaded Stud Steel / Stainless Steel

Information

Ball jointed leveling feet GN 638 are used for installing and leveling devices or for pressing and clamping.

The thrust pad of NBR has anti-slip, dampening and noise-reducing properties and prevents damage to sensitive surfaces. The disk is encased in vulcanized rubber to ensure height load capacity and dimensional stability.

Together with the thrust pad, the ball thrust point forms a ball joint that adapts to mounting surfaces that are uneven or not perpendicular to the screw axis. It also prevents the clamping surface from rotating when the thrust pad is in contact to the clamping surface.

The ball jointed leveling feet are supplied unassembled. The ball thrust point of the threaded stud can be easily pressed into the thrust pad and removed again if needed. The ball diameter d₃ is smaller than the core diameter of the thread, with the effect that the threaded stud can be screwed in on the ball side.

The indicated static load serves as a guide value; a corresponding safety factor must be additionally taken into account depending on the application.
