ABSTRACT:
A bearing set for a ball and socket joint comprises an inner and outer bearing with a head of a ball stud engaging a spherical inner seat face of each of the bearings. An axial compression pre-load results when the bearing set and ball stud are inserted into a socket and the socket is closed. To prevent the over compression of the bearings and undesirable plastic deformation, a plurality of wedge shaped slots extend about each bearing between an outer axial surface and an outer peripheral surface. The slots provide material "flow" which eliminate unwanted plastic deformation by placing pre-load force and the natural material elasticity into a desired equilibrium. The tailored "cushioning" effect remains while still providing adequate compression pre-loading and dynamic stability to the ball stud.
