Abstract
A multilayer aluminum-base alloy bearing formed by bonding a bearing alloy layer made of an aluminum-base alloy to a steel back metal through an intermediate layer made of an aluminum-base alloy, the intermediate layer being composed of two layers, that is, a lower layer and an upper layer, the lower layer in contact with the steel back metal being lower in hardness than the upper layer. Since the lower layer is soft, it is excellent in bonding property for the back metal, and since the upper layer is hard, it withstands a load exerted on the bearing alloy layer.
