Abstract
A composite copper alloy bearing is provided with a backing metal layer, an intermediate layer of Cu--Pb alloy, and a surface layer of Al--Sn alloy. A thickness of the surface layer is not less than either larger value selected between 0.06 mm and a value 0.2 times the sum of thicknesses of the intermediate layer and the surface layer but not more than a value 0.5 times the sum of the thicknesses of the intermediate layer and the surface layer. With this construction, the surface layer exhibits excellent sliding properties while the intermediate layer maintains high conformability, and therefore there can be provided the composite copper alloy bearing which has high fatigue strength particularly even in a case where a shaft susceptible to misalignment is used.
