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.

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. The invention further relates to a device for determining the protrusion of bearing shells, comprising a clamping device, which is suitable for clamping a bearing shell at one or more bearing points, one or more deformation apparatuses, which are suitable for applying one or more test forces to at least one point of the bearing shell, one or more measuring devices, which can measure the deformation of the bearing shell at one or more points when one or more test forces are applied by the deformation apparatus to at least one point of the bearing shell in such a way that the bearing shell is elastically deformed, and an apparatus for determining the protrusion, which can determine the protrusion of the bearing shell from the measured deformation of the bearing shell.

A thrust washer () in the form of a semi-circular flanged ring includes at least two radially inward-directed outer connection pieces () on the inner edge of the thrust washer () for the connection with a radial bearing part (), which are located in the circumferential direction on both sides of a contrived centerline (M) of the thrust washer () and in each case have an inner edge () facing the center line (M) and an outer edge () 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 () in each case include an angle (&#x3b1;), which is 45&#xb0; and 85&#xb0;, with a tangent on the inner side connected in the center of the connection piece () at the semi-circle described by the thrust washer (), in which the outer edge () runs parallel to the respective inner edge (). Such a thrust washer () can be connected with a radial-axial bearing () with a radial bearing part ().
