Are ceramic bearings anti-corrosion?

Yes. Ceramic bearings are more resistant to corrosion than stainless steel bearings.

The reaction speed of the ceramic itself with the acid and alkali is very, very slow, so simply from the point of view of acid and alkali corrosion resistance, the life of the ceramic bearing is many times longer than that of the stainless steel bearing.

Ceramic bearings run, if the ceramic material does not do micro-welding, then the ceramic bearings do not need to use lubricating oil. This is because lubricating oil is only needed when the micro-welding interacts frictionally with the metal, rolling elements and raceway surfaces.

As far as the current use of ceramic bearings is concerned, most of them will not encounter this situation, so ceramic bearings do not need to use lubricating oil.

2, ceramic bearings need to use lubricating oil

Ceramic bearings in the use of the process, if the use of time for a long time, then the flexibility of ceramic bearings must not be very good, then this time the ceramic bearings need to use lubricating oil.

At this time, the use of lubricating oil can reduce bearing wear, reduce bearing scrap rate, and ensure the normal service life of the bearing. In addition to the following benefits:

(1) Cleaning effect: Long-term work of the bearing will produce fine powder, and the lubricating oil will take away part of the powder to avoid damage to 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 friction.

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