Abstract

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