Abstract: The invention relates to a composite antifriction bearing material for producing antifriction bearing elements, in particular antifriction bearing bushes and antifriction bearing half liners for engine applications, comprising a steel carrier layer and a copper-based, in particular copper-tin-based or copper-zinc-based bearing metal layer applied on top, and comprising an aluminum-based running layer sputtered onto the bearing metal layer; to improve the running-in behavior, applied to the sputtered-on running layer is an additional running-in layer, which is either a zinc-phosphate layer 1-5 ?m thick formed on the surface of the running layer or a layer of tin, bismuth, silver or alloys thereof 1-5 ?m thick sputtered onto the running layer, but softer than the latter, or a polymer-based antifriction coating less than 10 ?m thick.

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.

Abstract: The invention relates to a plain bearing composite material comprising a steel carrier layer, a carrier layer which is cast, sintered or cladded thereon, the carrier layer being made of bronze or brass, and a bearing coating on the carrier layer or on an intermediate layer, the bearing coating being made of a bearing coating material based on aluminium/tin/copper, to increase load-bearing capacity and resistance to wear of the plain bearing composite material. According to the invention, the composition of the plain bearing materials is AlSn(22-30)Cu(2.3-2.8), optionally, comprising upto 2 wt. % Ni, Si, Mn and impurity related elements up to, respectively, 0.5 wt. %, the total quantity thereof not amounting to more than 1 wt. %, and the hardness of the bearing coating being between 110-150 HV 0.002.
