ABSTRACT:
A sliding bearing has a back metal made of a copper alloy which has a high followability with respect to deformation of a light alloy housing, and with this construction, the sliding bearing is excellent in fretting resistance and migration resistance. The multi-layer sliding bearing for a light alloy housing includes an aluminum alloy bearing layer, and a back metal layer, the back metal layer being made of a copper alloy which has a thermal expansion coefficient of not less than 15.times.10.sup.-6 /.degree.C., a 0.2% yield strength of not less than 295 N/mm.sup.2 and a heat transfer coefficient of not less than 0.40 Cal/cm.cndot.sec.cndot..degree.C. A Pb-alloy overlay layer can be formed on the bearing layer. A bonding layer can be formed between the bearing layer and the back metal layer. A flash plating layer can be formed on an entire surface of the bearing. When a large interference is not obtained, or under sever conditions as when the temperatures of the bearing and the lubricating oil rise in a high-speed range of the internal combustion engine or as when the inertia force of the housing increases, an excellent bearing performance is achieved by the sliding bearing of the present invention.
