Differences in the selection of lubricating grease between hybrid ceramic bearings and ceramic bearings
1. Thermal stability: Ceramic bearings usually have good high-temperature resistance, so when choosing lubricating grease, high-temperature type lubricating grease can be considered. These lubricating greases have higher thermal stability and high-temperature resistance, and can maintain lubrication effect in high-temperature environments.
2. Friction and wear performance: Ceramic bearings usually require the use of low friction lubricating grease due to their low friction coefficient. Low friction lubricating grease can reduce friction and wear of bearings and improve overall efficiency.
3. Corrosion resistance: Ceramic bearings usually have high corrosion resistance to corrosive media due to their material characteristics. However, the selection of lubricating grease also needs to consider the presence of corrosive substances such as acids and alkalis in the environment. In corrosive environments, it is necessary to choose lubricants with good corrosion resistance.
For hybrid ceramic bearings, the metal part, like ceramic balls, also needs to consider the selection of lubricating grease. In general, conventional lubricating grease is usually used for metal parts, while ceramic ball parts can choose lubricating grease types similar to ceramic bearings, such as high-temperature and low-friction types.
When selecting lubricating grease, it is necessary to comprehensively consider factors such as working environment, temperature range, friction requirements, corrosiveness, and follow the recommendations of the bearing manufacturer to ensure good lubrication and performance of the bearing. Therefore, it is recommended to consult with the bearing manufacturer before using lubricating grease and make choices based on actual needs.
