What are the main applications of ceramic bearings?

ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetic and electrical insulation, oil-free self-lubrication and high speed. It can be used in extremely harsh environments and special working conditions, and can be widely used in aerospace, aviation, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, electricity, textiles, pumps, medical equipment, scientific research and defense, and military fields. High-tech products for new material applications. The rings and rolling elements of ceramic bearings are made of all-ceramic materials, including zirconia (ZrO2), silicon nitride (SisN4) and silicon carbide (Sic). The cage is made of polytetrafluoroethylene, nylon 66, polyetherimide, zirconium oxide, silicon nitride, stainless steel or special aviation aluminum and thus extends the application area of ceramic bearings.

What is the color difference between zirconia and silicon nitride in ceramic bearings?

More than 80% of zirconia ceramic bearings are mainly white, and the white zirconia ceramic ball has its natural color. But sometimes you see that the ceramic ball is pale yellow or gray, because the zirconia material contains a small amount of impurities.Zirconia ceramic balls have the advantages of high toughness, high bending strength and high wear resistance, excellent thermal insulation performance and thermal expansion coefficient, close to that of steel bullets.

The silicon nitride ceramic bearing is mainly made of soot. It is extremely high temperature resistant and its strength can be maintained at a high temperature of 1200°C without falling. After heating, it does not melt into a melt. It is one of the hardest materials in the world.

What are the special features of using ceramic bearings?

Speaking of corrosion resistance: Since ceramics are almost not afraid of corrosion, ceramic bearings are suitable for use in environments full of corrosive media.

Over the service life: Because the density of the ceramic ball is lower than that of steel and the weight is much lower, the centrifugal effect of the outer ring during rotation can be reduced by 40% and the service life can be greatly extended.

Regarding high-speed environment: Since the modulus of elasticity of ceramic is higher than that of steel, it does not deform easily when subjected to force, so it is advantageous to improve the working speed and achieve higher accuracy.

Available without adding grease: The ceramic bearing material itself has a high temperature resistance of 1200 °C and good self-lubrication. The operating temperature is between 100 °C and 800 °C without expansion due to temperature difference. It can be used in high temperature equipment such as furnaces, plastics and steels.
