How to prevent sliding bearing damage

SINO BEARINGSAug 25, 2022
The prevention methods
 
Prevention of paint rust: Paint rust is characterized in a sealed motor, at first the motor sounds good, but after a period of time in the warehouse, the motor becomes very abnormal sound, remove the bearing serious rust. Many manufacturers will be regarded as the problem of the front bearing. The main problem is that the volatile acid of the insulating paint at a certain temperature, humidity, corrosion and protection of metals, the formation of corrosive substances, and corrosion damage caused by the channel sliding bearing.
 
Sliding bearing life is closely related to manufacturing, assembly and use. Each link must be made to make the best bearing for the operation of the country, so as to prolong the service life of bearings.
 
1. In the process of producing coated machine bearings, some enterprises do not strictly comply with the requirements of cleaning and rust prevention regulations and oil seal rust prevention packaging for the coated machine bearing parts in the process of processing and the finished products of coated machine bearing after assembly. If the turnover time of the ring is too long in the turnover process, the outer ring contact with corrosive liquid or gas.
 
2. The quality of antirust lubricating oil, cleaning kerosene and other products used in the production of some enterprises cannot meet the requirements specified in the process technology.
 
3. As the price of bearing steel for coating machine falls again and again, the quality of bearing steel for coating machine gradually declines. For example, the content of non-metallic impurities in steel is high (the increase of sulfur content in steel reduces the corrosion resistance of the material itself), and the deviation of metallographic structure, etc. At present, the bearing steel used by the production enterprise is from miscellaneous sources, and the steel quality is mixed with fish and dragon.
 
4. The environmental conditions of some enterprises 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. In addition, the hot weather, production workers violate rust-prevention regulations and other phenomena are not lack of existence.
 
5, some enterprises of anti-rust paper, nylon paper (bag) and plastic cylinder coating machine sliding bearing packaging materials do not meet the requirements of rolling coating machine bearing oil seal anti-rust packaging is also one of the factors causing corrosion.
