The cause of INA bearing corrosion basically has two kinds: one is the bearing of the metal corrosion itself, and the second is human factors corrosion.

INA bearing itself of the metal corrosion in proportion account for most, because the needs of work , this is inevitable. People contact bearings, hands sweat can cause the INA bearing corrosion, mainly is sweat contact bearings in the surface will produce sweat membrane, interaction electrochemical reaction causes corrosion will happen, but it can be avoided, if take professional gloves tools to carry parts.

The reason of INA bearing corrosion of metal mainly embodies the follows:

1, surface finish;

2, metal material chemical structure and component;

3, the metal surface solution composition and PH value;

4, environmental media;

5, surrounding the humidity and temperature.

INA bearing the corrosion prevention measures are mainly: keep the bearing surface clean, and clean must use an appropriate method. General chemical dealing with cleaning, mechanical cleaning and have solvent such as cleaning method. Face clean compressed air can be used after drying blow dry, also can use 120 ~ 170 ℃ dryer for dry, then use clean dry gauze. Then on the bearing with temporary, specific as follows:

Use soaking method, oil film thickness can control the temperature of the rust or viscosity oil to achieve. Some small items by soaking in the rust of oil, make its surface adhesion on a layer of rust oil;

Use sparge law, of some large thing can't take immerse rust method with oil, apply to thin layer or solvent XiShiXing oily-type temporary, but be aware that labor and fire protection measures; and

 
Use brush besmear of, painted with not only to avoid when do not produce accumulation, also want to prevent result with the leak. Apply to don't share some of the special soaking or spraying appearanc
