This article presents the macro- and microstructural analysis of bearing raceways. Raceways of bearings, taken from two machines which had worked 100,000 and 30,000 h, were examined. This provided crucial information on the exploitation history of both bearings, which is especially important for the future design process. After these initial macroscopic observations, it was determined which areas of the bearing had been most severely worn. This was indicated by the areas in which the chassis stiffness was highest. Further microscopic analysis of the individual bearing sections was useful for the identification of the dominating, destructive mechanisms in these areas.
