Zirconium Oxide Bearing Balls Description

Zirconium Oxide Bearing Balls offer exceptional toughness, high flexural strength, and excellent wear resistance, making them a cost-effective alternative to silicon nitride ceramics in the ceramic bearing industry. They feature outstanding corrosion resistance suitable for acidic and alkaline environments, can withstand temperatures up to 500°C, and provide electrical insulation with non-magnetic properties. With a low density of 6.05 g/cm³—about 20% lighter than steel balls—they reduce noise and wear. Their self-lubricating nature allows operation without additional lubricants. Typical applications include ceramic bearings, high-temperature and vacuum bearings, chemical pumps, and ceramic valve balls.
