Ball joint thrust pads GN 346 are in general used for transfer of clamping forces. They adjust themselves to uneven or non-parallel surfaces and clamp without twisting the clamped parts.

 

The values were arrived at by a series of tests whereby a limited number of ball joint pads were subjected for a limited time to a vertical static load to the pads.

 

At the values given in the table a permanent deformation of the ball is almost impossible.

 

Ball joint thrust pads GN 346 can also be used as levelling feet with a small foot diameter.
