Lead free journal bearing

摘要

A lead-free journal bearing includes a cylindrical ferrous backing and a bearing alloy layer comprising a bearing alloy powder consisting essentially of 7 - 13 mass percent of Sn, 0.7 - 2 mass percent of Ag, optionally at most 0.5 mass percent of molybdenum disulfide, optionally at most 2 mass percent of graphite, and a remainder of Cu sintered to an inner surface of the backing. The bearing is particularly suitable for use in construction equipment.
