ABSTRACT:
For use in a railway car truck, a lubrication retaining shim bearing is arranged to be inserted between the railway car center plate and its associated center bowl on the truck bolster. The bearing includes an upper shim for engaging the railway car center plate, a lower shim for resting in the center bowl, and a middle shim having a plurality of apertures therethrough. A lubricant is retained between the upper and lower shims, and between the shims and their respective parts of the railway car. In an alternative embodiment, the upper and lower shims are fixed with respect to the railway car center plate and center bowl respectively, and the lubricant is confined between the upper and lower shims.
