Abstract
In a sliding surface layer, a bearing metal layer is provided on the inside surface of a backing shell and is formed on its inside surface with elongate recesses, which extend in the peripheral direction of the bearing and are distributed over the axial extent of the sliding surface of the bearings. These elongate recesses contain a relatively soft bearing material. In order to increase the fatigue limit and the wear resistance, the softer bearing material constitutes a continuous covering layer, which has on the lands of the inside surface of the bearing metal layer a thickness that is not in excess of 1.5 times the depth of the elongate recesses. The axial center spacing of the elongate recesses should not exceed an upper limit a.sub.o =500+0.5 d+0.01 d.sup.2 in micrometers, if d is the bearing diameter in micrometers.
