Abstract

A bearing ring includes a first ring part having a first peripheral surface forming a rolling body retaining track or a sliding surface and a second peripheral surface, and a concentrically arranged second ring part having first and second peripheral surfaces. The first and second ring parts are pressed together to plastically mold the second peripheral surface of the first ring part into the first peripheral surface of the second ring part through axial expansion. During manufacture, one tool grasps the first peripheral surface of the first ring part and presses it into a pre-determinable shape and another tool supports the second peripheral surface of the second ring part. The first ring part is pressed against the second ring part, with the contour of the second peripheral surface of the first ring part being plastically molded into the first peripheral surface of the second ring part through axial flow forming.
