Product description

Information

GN 638 grub screw and thrust pad assemblies are a low cost solution for clamping operations or for load bearing purposes.

Another good feature is a smaller size ball diameter than the trunk of the threaded stud. As a result, the studs can be screwed into position from the ball side. The thrust pad can easily be hammered onto the ball end of the screw, and also easily dismantled.

Static load capacity has been determined by a series of tests but are approximate. For these tests the loads were placed vertically and centrally over the stud. At the measured load of 3.5 kN there was no remaining deformation visible on the thrust pad nor was there any breakage.

A combination of these assemblies with any handle component will give useful clamping options.
