Abstract: Plain bearings, particularly thin-walled plain bearing liners, are provided with radial projections for fixing and as an aid to assembly, e.g. with lugs, on the outer side of the outer part of the bearing, without using the whole thickness of the outer part of the bearing, so that the inner surface of the outer part of the bearing, which carries the functional layer, remains along its whole length cylindrically curved and smooth. Such outer projections are formed on a part of the thickness of the outer part of the bearing by radial shaping of the material. This is made on the joint face of bearing liners or on one or the other of the axial end faces of bearing liners or bushes or also on any desired place of the outer peripheral surface of the outer part of the bearing.
