Abstract

A bearing material composition that lines a support includes a combination of a thermoplastic conforming material and abrasive particles which provide a combined effect for remedying the effects due to edge loading that may be caused by misalignment between the bearing and a shaft to which a portion is rotatably mounted. The conforming material may be PTFE such that it does not have a memory and is subject to cold flow and creep. As a result, misalignment problems and edge loading are remedied by the combination of abrasive removal of metal material from the drive shaft at the location of edge loading and creep of the conforming material at the location of edge loading which may provide an overall greater bearing interface surface.
