Bearing ring

A roller bearing or plain bearing comprising:

• an inner ring;
• and
• an outer ring,
• at least one of the inner ring and the outer ring comprising:
• a first ring part having a first peripheral surface forming a track or sliding surface and a second peripheral surface;
• a second ring part having a first peripheral surface and a second peripheral surface, the second ring part being positioned concentrically to the first ring part;
• the first ring part and the second ring part being pressed together with 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 in the second ring part.

A method for producing a bearing ring having a track for retaining rolling bodies or a sliding surface comprising:

• engaging a first peripheral surface of a first ring part with a first tool to press the first peripheral surface of the first ring part into a predetermined shape, the first peripheral surface of the first ring part constituting the track or sliding surface, the first ring part having a second peripheral surface;
• supporting a second ring part having first and second peripheral surfaces with a second tool so that the second tool supports the second peripheral surface of the second ring part;
• pressing the first ring part together with the second ring part through use of the first tool to plastically mold a contour of the second peripheral surface of the first ring part into the first peripheral surface of the second ring part through an axial flow forming process and form a bearing ring having the first and second ring parts arranged concentrically to one another;
• and
• removing the first tool from the first ring part and the second tool from the second ring part.
