ABSTRACT:
A captive ball and end connector assembly having an annular bearing half positioned within the cavity is disclosed. The bearing half has an inner spherical surface on which are disposed a plurality of crush elements or ribs, and a bottom planar surface on which is disposed an annular crush element or rib. The plurality of crush elements crush against the spherical surface of the captive ball, and the annular crush element crushes against an annular shoulder in the cavity to retain the ball within the cavity with a zero clearance. A ball retaining ring is disposed within a groove in the cavity and bears against the bearing half to hold the ball firmly in the cavity.
