Document Type and Number:
Japanese Patent JPS5486041
Kind Code:
A
Abstract:
A porous metal or alloy layer is formed by sintering or the like on a metal backing formed of steel, for example. Copper or a copper-base alloy is generally used for forming the porous metal or alloy layer. The porous metal or alloy layer having the metal backing is impregnated with a mixture comprising 1-25% by volume of lead fluoride, 1-30% by volume of one or both of lead and a lead-tin alloy consisting of 3-30% by weight of tin and the remainder being lead, and the remainder essentially polytetrafluoroethylene, wherein the lead fluoride and one or both of the lead-tin alloy and lead being 2-25% by volume in total, thereby a bearing material of this invention is provided. Depending on the use to which the bearing material is put, at least one additive selected from the group consisting of molybdenum, tungsten disulfide, cadmium oxide, aluminum oxide, calcium fluoride, lithium fluoride, graphite, lead iodide, glass fibers, carbon fibers and a phosphate may be contained in 0.1-5% by volume in the mixture, to improve the performance of the bearing. The bearing material of this kind is suitable for use in shock absorbers of vehicles or the like which move in reciprocatory sliding movement under varying loads.
