Abstract
The Cu system bearing material is disclosed, which comprises a backing material consisting of a steel strip, a sintered alloy layer formed on the backing material by sintering metal or alloy particles, and a bearing layer formed on the sintered alloy layer. The sintered alloy layer consists of a sintered alloy containing 14% to 20% by weight of Pb and 4% to 10% by weight of Sn with the remainder being Cu. This bearing material exhibits satisfactory fatigue strength and a wear-resistant property under high-load high-frictional-speed conditions.
