The stresses in structural components can appear due to different reasons: loading, manufacturing long-time operations, etc. One of the reasons for stresses appearance is the heat treatment to which components sometimes need to be subjected. Changes in the size and shape of products are manifestations in the heat treatment. Although those changes are undesirable, they cannot be completely avoided and/or eliminated. This article deals with the effect of the heat treatment on change of the size of bearing rings. The aim was to compare the dimensions before and after the heat treatment, to find out whether the changes are within tolerance ranges or if the additional processing of components would be necessary. Another aim was to monitor the effect of layout of bearing rings on dimensions change.
