Abstract: The invention relates to a plain bearing half liner for a crankshaft main bearing (24), with a slot (10) which extends in the circumferential direction over an angle of 90 to 170°, is closed at both circumferential ends of the plain bearing half liner and passes radially through the plain bearing half liner, and with an otherwise oil-groove-free sliding surface (11) on the inside of said plain bearing half liner.

Abstract: The invention relates to a sliding bearing element comprising a supporting layer, an aluminum alloy-based intermediate layer, and an aluminum alloy-based bearing metal layer. The aluminum alloy composition of the intermediate layer includes at least the following components in percent by weight: 3.5 to 4.5 of copper; 0.1 to 1.5% of manganese; 0.1 to 1.5% of magnesium; and 0.1 to 1.0% of silicon.

Abstract: The invention relates to a method for determining the protrusion of bearing shells, comprising the following steps: a) clamping a bearing shell at several bearing points; b) applying one or more test forces to at least one point of the bearing shell so that the bearing shell is elastically deformed; c) measuring the deformation of the bearing shell at one or more measuring points of the bearing shell; d) determining the protrusion from the measured deformation.

Abstract: A thrust washer (14) in the form of a semi-circular flanged ring includes at least two radially inward-directed outer connection pieces (22) on the inner edge of the thrust washer (14) for the connection with a radial bearing part (12), which are located in the circumferential direction on both sides of a contrived centerline (M) of the thrust washer (14) and in each case have an inner edge (23) facing the center line (M) and an outer edge (23a) turned away from the centerline (M). The invention also relates to a radio axial bearing with a radial bearing part and a thrust washer of such a type connected with the radial bearing part. The inner edges (23) in each case include an angle (?), which is 45° and 85°, with a tangent on the inner side connected in the center of the connection piece (22) at the semi-circle described by the thrust washer (14), in which the outer edge (23a) runs parallel to the respective inner edge (23).
