Bearing in the work, which will be due to changes in the size and structure of the material changes. This shift by temperature, time and stress influence.
In order to avoid changing the structure of the material and dimensional changes in the work is not allowed, the bearing materials must be special heat treatment.
Depending on the bearing type, standard bearings are hardenability and induction hardening heat treatment of steel with the recommended maximum operating temperature between 120-200 degrees. You can reach a maximum operating temperature of the heat treatment process has a direct relationship. If an application's normal operating temperature higher than the recommended maximum temperature, the higher should be used in a stable series bearings. If the bearing requires a continuous work at high temperature, dynamic load capacity of the bearing may need to make adjustments.
