(1) Steel for bearings
Common types of rolling bearing steel: high carbon bearing steel, carburized bearing steel, corrosion-resistant bearing steel, high-temperature bearing steel
(2) Lubrication of bearings after installation
Lubrication is divided into three types: grease, oil, and solid lubrication
Lubrication can ensure the normal operation of bearings, avoid contact between the raceway and the rolling element surface, reduce internal friction and wear of bearings, and improve the service life of bearings. Lubricating grease has good adhesion and wear and temperature resistance, which can improve the oxidation resistance of high-temperature bearings and enhance their service life. The lubricating grease in the bearing should not be too much, as excessive grease can have a counterproductive effect. The higher the speed of the bearing, the greater the harm. It will cause the bearing to generate a large amount of heat during operation, which can easily lead to damage due to excessive heat generation. So, scientifically filling lubricating grease is particularly important.
