ABSTRACT:
A wear member for use between a pair of relatively movable components of a railway vehicle and method of making the same are provided wherein the wear member has a support provided with a continuous supporting surface. Polymeric material is attached to the support and is supported by the continuous supporting surface thereof whereby the polymeric material has an outer antifriction wear surface. A comparatively rigid load-carrying member is embedded in the polymeric material and the load-carrying member serves to maintain the polymeric material free of substantial indentation under conditions of high impact loads applied simultaneously against the load-carrying member and the polymeric material, the load-carrying member having a peripheral side surface being engaged by the polymeric material completely around the entire peripheral side surface so that the load-carrying member is completely surrounded at the peripheral side surface thereof by the polymeric material.
