摘要

The invention relates to a method for producing rolling bearings characterized by the steps of: - producing at least two lots of reference components of the rolling bearings, the rolling bearings of the first lot being treated at least on certain surfaces by known hardening processes and the rolling bearings of the second lot having a specific surface treatment Measures for introducing mechanically introduced residual stresses at least on the surfaces are exposed; - Measuring and comparing the reference values and creating reference values by comparing residual compressive stresses at least on the specific surfaces of the bearings of the two lots (e.g. X-ray diffraction = X-ray diffraction); - Computational Determination of at least one correction factor on the basis of the comparison values - determination of basic data (for example dimensions and loads of the rolling bearings) for the use of rolling bearings; - Calculation of the service life using the generally known nten service life values based on the key data (bearing dimensioning) and including the correction factor; - production of rolling bearing components and surface treatment at least on the specific surfaces with the measures to which the reference components of the second lot were exposed.
