In the work, the size of the bearing will change due to changes in the material structure. This transition is affected by temperature, time, and stress.
In order to avoid unacceptable dimensional changes due to structural changes in the material during work, the bearing material must undergo special heat treatment.
Depending on the bearing type, standard bearings are made of hardened and induction hardened steel, and the recommended maximum operating temperature is between 120 and 200 degrees. The highest working temperature that can be reached is directly related to the heat treatment process. If the normal operating temperature of an application is higher than the recommended maximum temperature, a bearing with a higher stability level should be selected. If the bearing needs to work continuously at high temperature, the dynamic load capacity of the bearing may need to be adjusted.
