When the bearing is in operation, its size 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 operation, the bearing material must undergo a special heat treatment.
Depending on the type of bearing, standard bearings are made of hardened and induction hardened steel. The recommended maximum operating temperature is between 120 and 200 degrees. The maximum operating temperature that can be achieved 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 number of stable stages should be used. If the bearing needs to operate continuously at high temperatures, the dynamic load capacity of the bearing may need to be adjusted.
