Abstract
Sliding bearing 1 comprises a bearing alloy layer 2 having peaks of a height h, an intermediate layer 3 of a thickness y, and an overlay layer 4 having a thickness t at the top of the peak. The parameters h, y and t are chosen in a range which satisfies the inequalities: 1.ltoreq.h.ltoreq.8 (1), 0<y.ltoreq.2 (2) and 0.7 h.ltoreq.t.ltoreq.2 h (3). When a shaft journalled has a diameter D, the peak height h preferably satisfies the following inequality: 0.5D/10,000.ltoreq.h.ltoreq.1.25D/10,000 (4). In these inequalities, h, y, t and D are represented in unit of .mu.m. This choice improves the initial seizure resistance, the seizure resistance upon abrasion of the overlay layer and the wear resistance.
