    摘要： Disclosed is a sliding bearing having excellent fatigue resistance property under a high specific load. The sliding bearing has a back metal layer 2, an Al-base alloy intermediate layer, and an Al-base bearing alloy layer which contains grains of an intermetallic compound consisting of Al and at least two other elements. The grains include relatively smaller size grains each having a grain size of less than 0.5 μm. The smaller size grains are dispersed in the Al-base bearing alloy layer with a density of not less than eight grains per 1 μm2 in an optional sectional area of the Al-base bearing alloy layer

    摘要： The present invention has been made by the fact that the wettability with lubricant increases when tin grains are broken within a certain range. In an aluminum-based bearing alloy containing from 2 to 20 mass % of tin, the tin grains in a sliding surface have a size not less than 20 μm2 but not more than 50 μm2 expressed in region partitioned areas of the tin grains measured in accordance with a region partitioning method.
