ABSTRACT:
A bearing set for a ball socket joint comprises an outer bearing and an inner bearing with a head of a ball stud engaging a spherical inner seat face of each of the bearings. A compression pre-load is applied when the inner bearing is inserted into a cavity of the outer bearing, a cylindrical outer wedge surface of the inner bearing having a greater diameter than a corresponding diameter of an inner skirt defining the cavity of the outer bearing. The bearing set is subjected to additional compression pre-load when the bearing set and ball stud are inserted into a socket and the socket is closed. The two-piece bearing set promotes easy Joint assembly, results in a joint that is extremely tight with no axial or radial play, but allows necessary ball stud rotation and oscillation, and compensates for wear by a self-adjusting feature whereby some of the compression pre-load is released as wear takes place.
