The professor dissects; the main reasons for the formation of rust are as follows:
1. Some companies do not strictly follow the requirements of removing rust prevention regulations and oil seal rustproof packaging in the process of producing NSK bearings. The NSK bearing parts and NSK bearing products after the installation are rust-proofed. For example, the ferrule is in circulation. The turnaround time is too long in the process; the outer circle touches corrosive liquid or gas.
2. The quality of anti-rust lubricants and fire-fighting products used by some companies in production is not up to the requirements of process technology rules.
3. Because the price of NSK bearing steel drops and then falls; then the NSK bearing steel material gradually declines. If the content of non-metallic impurities in the steel is high (the increase of sulfur content in the steel makes the corrosion resistance of the data itself reduce); metallographic arrangement Deviation, etc. The NSK bearing steel used in the production company is more complicated; the amount of steel raw material is even more.
4, some companies have poor environmental conditions; high levels of harmful substances in the air; turnover places too. Yanyue apricots У 佬獯 佬獯. Plus the weather is hot; production workers against the anti-rust procedures and other appearances are also lacking.
5, some companies' anti-rust paper, nylon paper (bag) and plastic cylinder NSK bearing packaging materials do not meet the requirements of rolling NSK bearing oil seal anti-rust packaging is also one of the elements of rust formation.
6, some companies NSK bearing ring turning margin and grinding allowance partial. 庠 mining system is difficult (9) smoke 阄 阄 芡耆コ 芡耆コ 蛑 蛑 蛑.
