Abstract

A multilayer material for sliding surface bearings comprises a metal backing layer, a sintered porous bearing layer of a bearing metal, and a low-friction layer consisting of a mixture of PTFE and 5 to 30% by volume metal filler, and fills also the pores of the bearing layer. To reduce the wear the mixture of PTFE and metal filler contains also 5 to 40% by volume PVDF.
