INA Bearing corroded main reasons there are two: First, bearing metal corrosion, the second is the human factors of corrosion.
INA Bearing metal corrosion accounted for the vast proportion, because the needs of their work, many times this is unavoidable. Contact bearings, hand sweat can cause the INA Bearing corrosion, mainly sweat membrane sweat the contact bearing surface in its interaction will happen to the electrochemical reaction can lead to corrosion, but this is to avoid, such as to bring the professional to take gloves and other tools to take part.
INA Bearing metal corrosion in which the next points:
1, the surface finish;
2, metal materials, chemical structure and composition;
3, the metal surface of the solution composition and pH value;
4, environmental media;
5, the ambient humidity and temperature.
INA Bearing corrosion prevention measures are: to maintain the bearing surface is clean, and cleaning must use the appropriate method. General chemical treatment cleaning, mechanical cleaning and solvent cleaning methods. Clean the surface can be used dry compressed air, you can also use 120 ~ 170 ℃ dryer to dry, then dry with a clean gauze. Finally coated with anti-rust oil on the bearings, as follows:
Using the immersion method, the film thickness can control the temperature or viscosity of the anti-rust grease. Some small items by immersion in antirust oil, let a layer of anti-rust oil on the surface adhesion;
Using the spray method, and some large rust-proof material can not take the immersion coated with oil, apply to the thin layer of anti-rust oil or solvent dilution of anti-rust oil, but pay attention to the labor and fire protection measures;
Using the brushing method, brushing not only to avoid not produce accumulation, but also to prevent the leakage caused by Tu. Apply to sub-soaked or sprayed some of the special shape of the products or outdoor construction equipment.
