1. Composite bearing material for the manufacture of bearing shells and thrust rings for crank-shafts, consisting of a metallic backing (1), preferably a steel backing, with a 0.1 to 0.5 mm thick porous sintered-on or sprayed-on bearing metal layer (2) based on copper or aluminium, the pores of which are filled with a polymeric plastic and to which a 0.05 to 0.5 mm thick sliding surface layer of the same polymeric plastic is applied, characterised in that in order to obtain good silencing properties the polymeric plastic is polyether sulphone (PES). |
