What are the Main Properties of Full Ceramic Ball Bearings?

Full ceramic ball bearings can be used in various harsh conditions such as high speed, high temperature, low temperature, strong corrosion, strong magnetic field, vacuum and high pressure. Its main performance is as follows:

1. High bearing capacity. The hardness of ceramic material can reach up to 2 times of bearing steel, elastic modulus is 1.5 times of bearing steel, so the bearing capacity of ceramic bearing is also much higher than bearing steel bearing.

2. Good heat resistance. Ceramic materials in high temperature strength reduction is very small, even at 800 ℃ still maintain very high strength and mechanical properties, while ceramic materials thermal expansion rate of only 22% of the bearing steel, so high temperature dimensional stability is better.

3. High ultimate speed. The working speed of ceramic ball bearing can reach 13 times of the ultimate speed of the same type of bearing steel bearing.

4. Friction temperature rise is small. Ceramic ball bearings in 18000r/min speed operation temperature rise is about 60% of the temperature rise of the same conditions bearing steel bearings.

5. Friction loss is small. The same type of bearing, ceramic material quality than steel is small (about 40% of the bearing steel) operation of the rolling body by the centrifugal force and gyroscopic moment is small, small spin sliding, so the friction loss is significantly lower than the bearing steel bearings.

6. High wear resistance. Ceramic material hardness, wear resistance is very good, ceramic ball bearings are generally more than two times the working life of ordinary bearing steel bearings.

7. Good corrosion resistance. Ceramic materials can resist the corrosion of hydrochloric acid, sulfuric acid, caustic soda and other types of inorganic acids, organic acids, salts, alkalis and molten metals, but in hydrogen fluoride and molten iron, its corrosion resistance is poor, in use need to pay attention to.

8. Good insulation, low permeability. The resistance of ceramic material is 10 ° Ω, almost insulator, magnetic permeability is far less than 0.1H, adaptable to any non-magnetic parts.

9. Self-lubricating. Full ceramic ball bearings can achieve self-lubrication.
