1. Because the air contains more water, when the air humidity exceeds 70%, the surface of the smooth parts will absorb a very thin, human eyes can not see the body moisture adsorption film, when the temperature increases or decreases, it will be in the way of small dew solidified on the surface of the parts, again condensation can melt into a thin layer of shrinkage water, in this case, The bearing ring will quickly rust.

2. In summer, when human hands contact bearing rings, sweat will be left on the surface of parts. Sweat is a solution composed of edible salt and organic matter such as glacial acetic acid and lactic acid bacteria. Once everyone must touch after if not solved in time, it is easy to rust. There is a lot of organic waste gas and waste in the air, resulting in harmful hydrogen sulfide gas. In the case of wet and cold, it will also produce a variety of strong oxidants when in contact with water, which will lead to corrosion of bearing rings. Not fully cleaning the residual acid in a burned part can also lead to corrosion rust.

3. Bearing rings are treated with salt milk bath in the heat treatment process. In the future grinding production process, if the residual salt on the surface of the parts is not completely and completely eliminated, it will also bring corrosion. In addition, when the parts with residual salt are grinding, the acid salt will dissolve in the cutting fluid leading to mildew of the cutting fluid, and the parts will suffer the influence of the cutting fluid directly when cutting, resulting in rust.

4. Dust and residue are substances that promote corrosion, because generally dust and residue have water absorption. When encountering water in the air, it condenses into tiny water droplets, which attach to metal materials and produce etching. Therefore, workshop cleaning work is one of the measures in the production and manufacture of bearing rings.

5 in the cutting liquid hand disinfection, washing rags or other dirt, it is easy to lead to cutting liquid mildew loss of its anti-corrosion effect. Lead to corrosion in the bearing ring.

6. Follow the safe operation procedures of rust prevention treatment, and store the warehouse foundation in the bearing ring higher to prevent water storage. The storage space should be kept clean, and the corresponding ambient humidity should be kept between 45% and 60%, not more than 70%. The indoor temperature should be kept between 10 degrees and 25 degrees, and should not exceed 30 degrees. Otherwise the stock bearing ring is very easy to rust.
