Abstract: The invention relates to a big end bearing shell (4, 6) for a connecting rod (2), consisting of titanium or a titanium alloy. The shell comprises a support layer (8, 20) consisting of steel and an anti-friction layer (16, 26) for the crankshaft. According to the invention, the back of the support layer (8, 20) is clad with a layer (10, 22) of tin bronze material, with a thickness of 10-50 ?m to prevent fretting corrosion and frictional abrasion.

Abstract: The invention relates to a semicircular bearing element comprising a supporting layer (5) and a sliding layer (7) which is applied to the same. A holding element (6) projecting from a side of the supporting layer (5) facing away from the sliding layer (7) is provided, said holding element engaging in a correspondingly embodied recess (10) in a bearing housing element (2) in order to anchor the bearing element in the mounted state. The aim of the invention is to simplify the production and assembly of the bearing element. To this end, the holding element (6) is embodied in a polygonal manner in a cross-sectional plane, perpendicular to a radial direction (8) of the bearing element.
