Patent

CA 2092635

A low friction, high wear rail car center plate assembly of the type where a cylindrical center plate boss having a planar bottom surface and a perpendicular side wall rides rotationally in a mating bowl in a truck bolster, includes a boot which closely overlies the center plate boss, and axial and radial wear structures which fit within the bowl, so that the boot abuts the wear structures. The wear structures are preferentially formed of a composite bearing material, having an inner acetal resin surface, and the boot has a hard, highly polished surface. The boot includes an elastomeric or metallic seal ring cover that extends over the bowl and prevents foreign matter from getting between the bowl and the wear structures.
