Ceramic Balls 0.8/1/1.2/1.5/1.588~25.4mm Zirconia ZrO2/Si3N4 Bearing Balls

Material: ZrO2(G10) / Si3N4(G5)

Size tolerance: ± 0.0002mm

Feature: High precision, good wear resistance, high temperature resistance, high toughness, corrosion resistance, high stiffness, non magnetic, electrically insulated, smooth and easy to clean surface.

Scope of application: Semiconductor, LCD manufacturing equipment, electroplating equipment, synthetic fiber manufacturing equipment, optical film equipment, various heat treatment furnaces, vacuum equipment, etc; It can also be applied to composite bearings, cold working tools, various guide wheels, various valves, vacuum equipment, and various harsh environments.

Zirconia(ZrO2)G10 ceramic ball at 600℃, the strength and hardness remain almost unchanged, with a density of 6.00g/cm3 and a thermal expansion rate close to that of metals, making it suitable for bonding with metals.

Silicon nitrate(Si3N4)G5 ceramic ball at 800℃, the strength and hardness remain almost unchanged, with a density of 3.20g/cm3 and a weight one-third of that of bearing steel. When rotating, the centrifugal force is small, allowing for high-speed operation.

Ceramic ball products have stable performance, with silicon nitride having the best overall performance. Compared with steel, silicon nitride has a lighter weight, lower friction coefficient, better athletic performance, and a 50% higher elastic modulus. Moreover, the thermal expansion coefficient of silicon nitride is less than 25% of that of steel. It can maintain high strength and hardness before 1000 ° C at high temperatures, is corrosion-resistant, rust free, and non-magnetic, and can work under oil-free lubrication conditions.
