A bearing ring having a raceway along which rolling elements roll/slide comprises first 1, 17 and second 2, 18 ring parts each having first 4, 20, 7, 22 and second 5, 19, 8, 21 circumferential surfaces and arranged concentrically to each other. The first ring part 1, 17 is harder than the second 2, 18 (which has a radially outwardly facing flange 9) and both are concentrically pressed together (with the aid of a first removable tool 10, 25 Fig 1b which presses the first and second parts to form a bearing ring, and a second removable tool 12, 27 Fig 3b which supports the second surface of the second part) so that the second surface 5, 19 of the first ring 1, 17 are plastically moulded (by an axial flow forming process) to the first surface 7, 22 of the second ring 2, 18. The second surface of the first ring part is cylindrically shaped, having a reduction in cross-section due to an increase in linear and nonlinear axial deviation towards the end face (Figs 2b and 4b). |
