CM6734 Zirconium Oxide Bearing Balls, ZrO2

Product Description

Zirconium Oxide Bearing Balls deliver remarkable toughness, high flexural strength, and superior wear resistance, positioning them as a cost-effective substitute for silicon nitride ceramics in the bearing industry. These balls exhibit excellent corrosion resistance, making them suitable for both acidic and alkaline environments. They can withstand temperatures up to 500°C and provide electrical insulation with non-magnetic properties. With a density of approximately 6.05 g/cm³—about 20% lighter than steel—they help reduce noise and wear. Their self-lubricating characteristic enables operation without the need for additional lubricants. Common applications include ceramic bearings, high-temperature and vacuum bearings, chemical pumps, and ceramic valve balls.
