A rigid bearing assembly designed to achieve a low tolerance fit to an imprecisely sized, misaligned, out-of-round or otherwise distorted suspension member. Assembly is comprised of a rigid bearing enveloped with a elastomer layer. The elastomer layer is disposed between the bearing and suspension member. Upon insertion of the assembly into the suspension member, the elastomer layer compresses slightly to absorb irregularities and broad manufacturing tolerances in the suspension member while insulating the rigid bearing from distortion. The rigid bearing provides low-friction movement of suspension members about an axis. The polymer layer is sufficiently hard to provide precise location of suspension members under load. The ability to isolate the bearing from irregularities enables lower cost of production of all components. This same ability facilities easy retrofit of the invention to suspension members originally designed for rubber bushings without need for custom fitment or specialized tools.
