Abstract: The invention relates to a method for hardening running surfaces of roller bearing components, in particular outer bearing rings. In order to provide the edge area (functional layer) of the roller bearing components with a deep layer which is particularly hard and resistant to corrosion, the roller bearing component undergoes nitration for a long period of time at a temperature of between 450 and 650° C. and for at least 25 hours. During said treatment no carburizing and subsequently no quenching takes place.

Abstract: A roller bearing having two cooperating rolling parts of which one is of ceramic and the other of a steel. The steel part is of such structure and/or material and/or is so produced to cause residual compressive stresses to form beneath the contact surface of the steel part, at least in a load-free state, down to a depth.
