Why bearing 6302 easy to rust?

There are many reasons for rust corrosion of bearing 6302. The main reasons are as follows:  
1, some enterprises in the production of bearing 6302 in the process of not strictly according to the requirements of cleaning rust prevention regulations and oil seal rust prevention packaging bearing 6302 parts in the process of processing and assembly bearing 6302 finished products for rust prevention treatment.   
2, some enterprises in the production of anti-rust lubricating oil, cleaning kerosene and other products can not meet the requirements of the technical requirements.  

3, because the price of bearing steel drops again, resulting in a gradual decline in the quality of bearing steel.  For example, the content of non-metallic impurities in steel is high, metallographic structure deviation, etc. The bearing steel used by production enterprises is more miscellaneous, and the quality of steel is fishdragon mixed beads.  

4, the environmental conditions of some enterprises are poor, the content of harmful substances in the air is high, the turnover site is too small, it is difficult to carry out effective rust prevention treatment. In addition to the hot weather, production workers in violation of rust regulations and other phenomena also exist.  
5, some enterprises of anti-rust paper, nylon paper (bag) and plastic cylinder bearing packaging materials do not meet the requirements of rolling bearing oil seal anti-rust packaging is also one of the factors causing rust.  
6.The turning allowance and grinding allowance of some bearing 6302 rings are small, and the oxide skin and decarbonization layer on the outer circle are not completely removed.  
7. The so-called bearing 6302 made by some enterprises are actually made of carbon steel, so they are easy to be rusted and corroded.
