METHOD OF MANUFACTURING A BEARING RING

摘要

The present invention resides in a method of manufacturing a bearing ring (101) for a rolling element bearing, wherein the bearing ring comprises a bearing race (102) made of a bearing grade steel and an overmoulded part (106) that is preferably made of a lightweight metal such as aluminium or a thermoplastic material such as polyamide. According to the invention, the method comprises a step of hardening at least a raceway surface (103) of the bearing race prior to a step of joining the overmoulded part (106) to the bearing race (102) in a moulding process. In a further development, the method comprises a step of temperature control, to ensure that the temperature of the raceway surface (103) is kept below a predetermined value during the moulding process.
