ABSTRACT:
There is disclosed a novel aluminum alloy bearing which exhibits a more excellent fatigue resistance than conventional bearings even under such conditions of use as at a high temperature and under a high load. The aluminum alloy bearing has an aluminum bearing alloy layer containing, by weight, 1 to 10% Zn, 0.1 to 5% Cu, 0.05 to 3% Mg, 0.1 to 2% Mn, 0.1 to 5% Pb, 0.1 to 2% V, and 0.03 to 0.5% in total of Ti--B, and further may optionally contain not more than 8% Si, 0.05 to 0.5% Sr, and Ni, Co and Cr. The alloy may be bonded to a steel metal back sheet, and a surface layer may be formed on the surface of the bearing. By use of the composition of the alloy of the invention, the fatigue resistance of the aluminum alloy bearings has been improved, and such an improved bearing can fully achieve a bearing performance even under severe conditions of use as at high temperature and under a high load.
