In the case of needle roller bearings, the needle roller bearings should be put on the shelf according to the specifications within the validity period of the anti-rust liquid. Use an anti-rust liquid with a valid period of three months. In addition, the demagnetization is not clean, dust is adsorbed on the surface of the needle roller bearing, it is difficult to clean, and rust will also occur.
For example, use the acid etching method to fill in the marks and neutralize them. If they are treated, they will all promote rust. When the expiration date is approaching, Mechanical ball bearing Factory re-check the anti-rust. During the production process, needle roller bearings often encounter strong corrosive substances such as acids and alkalis. If there is no strict compliance with regulations, the stock needle roller bearings should be treated with anti-rust. Lax implementation of anti-rust regulations also all affect the corrosion of needle roller bearings.
Qualified needle roller bearings are generally stored in the assembly parts warehouse for a short period of time. It is not good to cause corrosion.The process of producing needle roller bearings is very strict. When they cannot be assembled for more than 8 hours (4 hours in hot season), they need to be rust-proofed. They cannot be assembled for a long time.
Or the preparation of the anti-rust solution is not up to standard: without anti-rust gloves, washing hands from time to time to remove sweat from the hands will cause the needle roller bearing parts to rust. The above content hopes to be helpful to everyone. If you need more information, please continue to pay attention to needle roller bearings! We will serve you wholeheartedly!. In order to prevent the needle bearing from rusting, the assembly room must ensure a small temperature difference, control the relative humidity of the environment, and purify the air
