CM6734 Zirconium Oxide Bearing Balls

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.

Zirconium Oxide Bearing Balls Applications

·          Ceramic Bearings: Used in high-performance ceramic bearing assemblies for enhanced durability and lower maintenance.

·          High-Temperature Bearings: Suitable for bearings operating in temperatures up to 500°C.

·          Vacuum Bearings: Ideal for vacuum environments due to their chemical stability and non-magnetic properties.

·          Chemical Pumps: Resistant to corrosive chemicals, making them perfect for pumps handling acidic or alkaline fluids.

·          Ceramic Valve Balls: Used in valves requiring high wear resistance and corrosion resistance.
