Does Ceramic Bearing Need Working With Grease Or Oil

Does ceramic bearings need lubricating with oil or grease ?

1.Ceramic bearings do not require lubricant


For ceramic bearings, if ceramic materials are not micro-welded, ceramic bearings do not need to use lubricants. Because only when micro-welding frictional interactions with metals, rolling elements and raceway surfaces, lubricants are needed. Judging from the current use of ceramic bearings, most of them will not encounter this situation, so ceramic bearings do not need to use lubricants.


2.Ceramic bearings need lubricating oil?


In the process of using ceramic bearings, if it has been used for a long time, then the flexibility of ceramic bearings must not be very good, so do ceramic bearings need to use lubricants at this time? The answer is needed. The use of lubricating oil at this time can reduce bearing wear, reduce the bearing scrap rate, and ensure the normal service life of the bearing. In addition, it has the following benefits:


(1) Cleaning effect: Long-term work of the bearing will produce fine powder, and the lubricant will take away some of the powder, so as not to damage the oil film.


(2) Lubrication: When the shaft rotates, an oil film is formed between the shaft and the dynamic and static parts of the bearing to prevent static and dynamic friction.


(3) Cooling effect: The shaft works at high temperature, and the temperature of the bearing is also very high. When the lubricant flows through the bearing, it takes away some heat to cool the bearing.
