Ceramic Balls

LILY Bearing provide a wide range of ceramic ball options across a variety of sizes. Material options include Silicon nitride (Si3N4), Zirconia (ZRO2), Alumina (Al2O3) and Silicon carbide (SIC) from 0.4mm to just over 115mm in diameter with the most common sizes in between.

Silicon Nitride Balls

Silicon Nitride Balls

Silicon nitride ceramic balls have high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, can be used in seawater for very long time, and have good performance of electrical and magnetic insulation. At 800 ℃, the strength and hardness are

Zirconia Balls

Zirconia Balls

Zirconia ceramic balls have high strength and toughness, good wear resistance, high temperature and corrosion resistance, high stiffness, non-magnetic conductivity, electrical insulation. At 600 ℃, the strength and hardness of the zirconia ceramic balls are almost unchanged, the density is 6.00g/cm3

Alumina Balls (≥99.7%)

Alumina Balls (≥99.7%)

Alumina ceramic balls are wear-resistant, heat-resistant, oxidation-resistant, water-resistant, corrosion-resistant from other chemicals and acids. Another feature is the ability to maintain dimensional stability up to 1100°C. Mainly used for pumps, valves, flow meters.
