Abstract

A plain bearing assembly of a rotational element on a bearing bolt includes a bearing bolt, a bearing sleeve, which is non-rotatably mounted on said bolt and which comprises a first radial bearing surface formed on its outer periphery, and a rotational element which is rotatably mounted on the bearing sleeve and which is mounted on the first radial bearing surface via a second radial bearing surface in such a way that it can slide. Axial bearing washers, which project radially beyond the bearing sleeve, are secured to both end faces of the rotational elements. The washers run against axial bearing surfaces of the bearing sleeve, and axial flanks of the bearing sleeve form axial bearing surfaces for the axial bearing washers.
