The main causes of corrosion are the following:
1, some companies in the process of production of bearings in strict accordance with the requirements of cleaning rust-proof procedures and anti-rust oil seal packaging bearing parts in the processing and assembly of the bearing finished rust. Rings in the turnover process, turnaround time is too long, the outer cylindrical contact with corrosive liquids or gases.roller thrust bearings
2, part of the enterprise anti-rust lubricant, cleaning, such as kerosene used in the production quality of the product of less than the requirements of the technology requires.
3, a gradual decline in bearing steel prices dropping lower and lower, resulting in bearing steel. High levels of non-metallic impurities such as steel (steel sulfur content increased to make the material their own anti-corrosion performance degradation), such as microstructure bias. Now sources of bearing steel production enterprises with more complex, the quality of steel is more of ichthyosaur mixture.
4, some enterprises of the poor environmental conditions, the air content of harmful substances, the venue is too small turnover, it is difficult to carry out effective rust treatment. Coupled with the hot weather, production workers in violation of antirust regulations, etc. is also no lack of existence.tool bearings
5, some enterprises, rust-proof paper, nylon paper (bags) and plastic tube bearing packaging materials do not meet the requirements of rolling bearing oil seal rust-proof packaging is also one of the factors causing corrosion.
6, some enterprises turning of the bearing rings margin and grinding margin is too small, the oxide on the outer decarburized layer can not be removed completely is also one of the reasons.thrust roller bearing
