Abstract
A sliding bearing bushing has a first end side, a second end side, an inwardly cylindrical second longitudinal portion which is calibrated by a material compression and adjoins the second end side, a substantially hollow conical first longitudinal portion which adjoins the first end side, and a third longitudinal portion which is arranged between the first and second longitudinal portions, the third longitudinal portion transferring bend-free from a contour of the second longitudinal portion into a continuous curvature so that, in a contour of the cylindrical portion straight lines located parallel to a longitudinal axis of the sliding bearing bushing are tangents to a curvature, and at least in a region of the tangents at the curvature the material of the sliding bearing bushing is compressed by calibration substantially identically strong as in the cylindrical longitudinal portion.
