ABSTRACT:
A ball joint has a stud with a ball end disposed in a housing in abutting engagement with an improved bearing. The bearing has a plurality of segments disposed in a circular array. A plurality of flexible connector sections interconnect the segments. As originally formed, the bearing has generally cylindrical outer side surface with a diameter which is less than the diameter of an inner side surface of the housing. This facilitates insertion of the bearing into the housing during assembly of the ball joint. The ball end of the stud applies force against a circular array of bearing segments to expand the circular array of bearing segments outwardly into engagement with the inner side surface of the housing. The bearing segments are interconnected by flexible connector sections which are deflected, as the bearing segments move outwardly, to accommodate expansion of the circular array of bearing segments.
