Abstract

The invention relates to a plain bearing shell for supporting an engine crankshaft or camshaft, or as a connecting rod bearing shell of an engine, the plain bearing shell comprises a radially outward protruding holding projection in the region of the separating surface of the plain bearing shell. In order to simplify handling of the plain bearing shell during assembly, the bearing shell is formed in such a way that the holding projection merges continuously into one separating surface of the plain bearing shell, and is formed by a stamping tool from the outside of the plain bearing shell by an approach in which, in the region of the separating surface, the stamping tool compressively deforms the material on the outside of the plain bearing shell, essentially tangentially relative to the plain bearing shell and toward the separating surface, while a counter-holding mechanism is applied to the separating surface, to which mechanism the formed material of the holding projection extends.
