<p>A molded bearing plate (24) of ultra high molecular weight polyethylene is formed with a bearing surface and series of strong, spaced, integrally formed posts (44, 46) extending from the opposed surface (38). A metal support plate (10) is provided with a series of perforations (22) through which the posts extend. The posts may have exteriorly threaded surfaces (46), and internally threaded fasteners (54) may be threaded onto the posts (46) to secure the molded bearing plate (24) to the support plate (10). The posts (44, 46) are integrally formed with the bearing plate (24) in a compression molding operation, and offer sufficient tensile strength to firmly attach the bearing plate (24) to the metal plate (10). The bearing plate assembly is particularly suitable for use as a fifth wheel assembly.</p> |
