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.

Manufacturing Process
1. Testing Method
(1) Chemical Composition Analysis - Verified using techniques
such as GDMS or XRF to ensure compliance with purity requirements.
(2) Mechanical Properties Testing - Includes tensile strength,
yield strength, and elongation tests to assess material performance.
(3) Dimensional Inspection - Measures thickness, width, and
length to ensure adherence to specified tolerances.
(4) Surface Quality Inspection - Checks for defects such as
scratches, cracks, or inclusions through visual and ultrasonic examination.
(5) Hardness Testing - Determines material hardness to confirm
uniformity and mechanical reliability.
Please refer to the SAM testing procedures for detailed information.
