A sheet material for sliding surface bearings comprises an expanded metal mesh which consists of a wrought aluminum alloy and is coated with a mixture of polytetrafluoroethylene, filler and glass fibers. The bond strength is increased by coating the surface of the expanded metal mesh with a primer layer.

Material for sliding surface bearings

A composite material for sliding surface bearings comprises a gacking shell of steel, which is covered by a bearing metal layer of sintered porour bronze having a porosity of 25 to 45%. The voids of the bronze layer are filled with a fluorocarbon-lead mixture. The bearing metal layer is covered by an anti-friction layer consisting of the fluorocarbon-lead mixture in a thickness of, for example, 30 to 500 microns. To permit of a machining of the anti-friction layer the bronze layer has a thickness of 250 to 350 microns and a porosity of 25 to 45% and the fluorocarbon-lead mixture comprises 30 to 60% by weight polyvinylidene fluorinde and 20 to 50% by weight lead.
