What is the cause of high temperature bearing corrosion?

The cause of high-temperature bearing corrosion and the determination of prevention methods firstly depends on what causes the high-temperature bearing corrosion, which is generally divided into external and internal causes.
In summary:
1. Surface finish of high temperature bearing metal (poor oxygen concentration, battery corrosion).
2. The chemical composition and structure of the high temperature bearing metal material itself.
3. The composition and pH value of the solution in contact between the high temperature bearing and the metal surface;
4. The ambient temperature and humidity of high temperature bearings.
5. Various environmental media where high temperature bearings are in contact with metal surfaces.
6. Other people's sweat is also the cause of high temperature bearing corrosion, and its pH value is 5-6. Therefore, in order to prevent corrosion caused by hand sweat, installation and production personnel should wear gloves and do not touch the high-temperature bearings with their hands.
