Abstract
A ball and socket joint includes a stud having a shank connected to a ball stud, which is received in a ball stud housing. A one piece bearing shell is provided having a generally spherically shaped hollow body with an inner surface to matingly engage the ball stud and an outer surface for contacting the stud housing. Moreover, the outer bearing shell surface includes a first spherical portion having a first radius and first center and a second spherical portion having a second radius and second center. The first and second centers are axially offset relative to each other to create a converging sphere design that permits a low profile design. The converging sphere design also permits more effective compression pre-loading on the bearing sleeve as compared to a single spherical outer surface.
