ABSTRACT:
In an aluminum base alloy bearing, the effect of reinforcement of an aluminum base bearing alloy layer by an intermediate bonding layer is enhanced, thereby enhancing a fatigue resistance of the aluminum base bearing alloy layer. The aluminum base alloy bearing comprises a back metal layer, the intermediate bonding layer, and the aluminum base bearing alloy layer. The hardness of the intermediate bonding layer is in the range of 25 to 60 in terms of Vickers hardness, and the thickness of the intermediate bonding layer is 0.5 to 0.9 times in the sum of both the thickness of the intermediate bonding layer and the thickness of the aluminum base bearing alloy layer. With this construction, the effect of reinforcement of the aluminum base bearing alloy layer by the intermediate bonding layer is enhanced, thereby enhancing the fatigue resistance.
