Abstract
A method of resisting wear between a body center plate of a body bolster of a railway vehicle body and a bolster bowl of a truck bolster of a truck of the railway vehicle is provided by disposing a wear resistant tubular liner to be sandwiched between the cylindrical surfaces of the body center plate and the bolster bowl. The tubular liner comprises an ultra high molecular weight polymeric material and has a top surface. A continuous metal ring is fixed to the flange of the bolster bowl against a top portion of the inside surface thereof before the liner is disposed in such bowl. The ring serves to engage the top surface of the tubular liner and prevent vertical cold flow of the polymeric material thereof from between the cylindrical surfaces.
