Abstract

See full text

A slide bearing including a metal backing; an Al-based intermediate layer; and an Al-based bearing alloy layer is disclosed. The Al-based bearing alloy layer includes one or more types of intermetallic compounds containing Al and two or more other types of elements, the Al-based bearing alloy layer including 8 or more grains of intermetallic compounds per μm2 having a grain diameter less than 0.5 μm. When the elements constituting the intermetallic compound are represented as X1, X2, . . . , Xn (n is a positive integer), a relative abundance of the elements satisfy X1≧X2≧ . . . ≧Xn. An abundance ratio X1/X2 of element X1 to element X2 ranges from 1 to 10. The Al-based bearing alloy layer has a Vickers hardness ranging from 50 to 80.
