Do you know the 6 main causes of bearing corrosion!

Release time:


1. In the process of bearing production, there is no anti-rust treatment for bearing parts in the processing process and finished bearing products after assembly in strict accordance with the requirements of cleaning and anti-rust regulations and oil seal anti-rust packaging. For example, the turnover time of the ferrule is too long in the turnover process, and the outer circle of the outer ring contacts corrosive liquids or gases.

(2) Used in productionanti-rust oilThe quality of cleaning kerosene and other products can not meet the requirements of process technology, and special solvent-based hydrocarbon cleaning agent and lubricating oil need to be used in use.

3. As the price of bearing steel drops again and again, the material of bearing steel gradually declines. For example, the content of non-metallic impurities in steel is high (the increase of sulfur content in steel makes the corrosion resistance of the material itself decrease), the deviation of metallographic structure, etc. At present, the bearing steel used by the production enterprises is mixed, and the quality of the steel is mixed with fish and dragon, which affects the development of the bearing industry.

The environmental conditions are poor, the content of harmful substances in the air is high, and the turnover site is too small to carry out effective anti-rust treatment. Coupled with the hot weather, production workers in violation of anti-rust regulations and other phenomena also exist.

5, some enterprises of anti-rust paper, nylon paper (bag) and plastic tube and other bearing packaging materials do not meet the requirements of rolling bearing oil seal anti-rust packaging is also one of the factors causing corrosion.

6. The turning allowance and grinding allowance of the bearing ring are too small, and the oxide scale and decarburized layer on the outer circle cannot be completely removed.
