ZrO2 ceramic balls description

Due to the features of high fracture toughness, high bending strength, high wear resistance, excellent heat insulating property and proper thermal expansion coefficient that closes to steels, Zirconia (ZrO2) ceramic balls are widely employed in ceramic bearing fields. Furthermore, the cost is much lower than silicon nitride.

Material Characteristic

1. Corrosion resistance, which can also be used in acid and alkali situation.
2. High temperature resistance, Witch remain the same strength and hardness when the temperature nearly comes to 550 ℃
3. Nonmagnetic, Electrical insulation. Which can be used in magnetic field
4. Zro2 ceramic balls have a low density of 6.05g/cm3.it is approximately 20% lighter than steel ball, Witch decrease the centrifugal force on the deep groove, in order to reduce the wear and tear.
5. Excellent resistance to oxidation and metal erosion, Zro2 ceramic balls also can be used without lubricate environment
6. Low friction coefficient and high surface finish.

Application fields

High precise ceramic bearing, high temperature bearing, vacuum bearing, nonmagnetic bearing, chemical pump, high temperature pump, ceramic valve ball, measure ball, etc.
