FAG bearings corrosion causes and prevention

The causes and prevention of corrosion of FAG Bearings FAG Bearings corrosion is caused by a variety of intrinsic and extrinsic factors, summarized in:
A metal surface finish (the difference of oxygen concentration cell corrosion).
2, the metal material chemical composition and structure.
3, the solution in contact with the metal surface composition and pH value;
4, the ambient temperature and humidity.
5, with the metal surface in contact with the various environmental media.
6, another human sweat also lead bearings corrosion, and its pH value of 5 to 6. Therefore, in order to prevent hand sweat caused by corrosion, installation and production personnel should wear gloves, do not just hand contact with the FAG Bearings.
Coated with anti-rust oil to prevent the rusting of FAG Bearings
Immersion: soaked some small FAG bearings used in antirust oil film thickness by controlling the temperature or viscosity of the antirust oil to achieve. Antirust oil to the surface layer on the adhesion.
2, the method of brushing: Brush attention to spread evenly in the FAG bearings surface, do not produce accumulation and pay attention to prevent leakage Tu.
3, the spray method: some large rust-proof material not suitable for immersion oiling, usually with about 0.7Mpa pressure filtration of compressed air to spray the air clean place. The spray application of the diluted anti-rust oil or a thin layer of anti-rust oil. This method must be used to improve fire safety and labor protection measures.
FAG bearings surface rust pre-treatment methods:
1, surface cleaning: cleaning must be combined with the nature of the FAG bearings surface and the prevailing conditions. Commonly used methods are solvent cleaning method, the method of mechanical cleaning and chemical treatment of cleaning method.
2, available filtering surface is dry and clean dry compressed air. Or use the dryer, the drying temperature of 120 ~ 170 ℃, and finally dry with a clean gauze.
