Abstract: The present invention related to a method, and an apparatus arrangement, for determining a fatigue limit for rolling contact initiated fatigue of a rolling bearing. The method comprises running a rolling bearing while being exerted to a load which generates sub-surface transformations in a rolling element contact zone of the outer or inner ring. Furthermore a set of sub-surface transformations in the contact zone along a raceway portion of the rolling bearing is identified and measured and used for generation of a parameter data set, wherein a fatigue parameter value representative of a predicted fatigue limit for the rolling bearing is determined based on the generated data set of sub-surface transformations.

Abstract: Method for heat treating a steel component (28, 36) comprising the steps of: a) carbonitriding the steel component (28, 36) at a temperature of 930-970°C, b) cooling the steel component (28, 36), d) re-heating the steel component (28, 36) to a temperature of 780-820°C and d) quenching the steel component (28, 36). The method comprises the step of either e) performing a bainite transformation at a temperature just above the martensite formation temperature, transforming 25-99% of the austenite into bainite at the temperature and then increasing the temperature to speed up the transformation of the remaining austenite into bainite, or f) holding the steel component (28, 36) at an initial temperature (T 1 ) above the initial martensite formation temperature (Ms), and lowering the initial temperature (T 1 ) to a temperature (T 2 ) that is below the initial martensite formation temperature (Ms) but above the actual martensite formation temperature during the bainite transformation.
