Industrial Precision Ceramic Balls High Toughness Zirconium Oxide Balls G5 G10
G5 G10 High Toughness Precision Industrial Zirconia Oxide ZrO2 Ceramic Balls
Description:
ZrO2 zirconia ceramic bearing balls offer high strength, toughness, temperature resistance, corrosion resistance, and non-magnetic properties. We offer a selection of high-quality zirconia balls in a range of sizes, including 0.031" to over 1.000"diameter for a variety of applications.Zirconia 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.
Key characteristics of zirconium oxide balls include:
-
Ultra-High Fracture Toughness & Impact Resistance: Possesses the highest toughness among conventional technical ceramic balls, effectively resists crack propagation and mechanical impact, avoiding brittle fracture under frequent dynamic loads.
-
Outstanding Wear & Abrasion Resistance: High surface hardness with extremely low friction coefficient and minimal wear rate, greatly extending the service life of moving components and reducing equipment maintenance costs.
-
Non-Magnetic & Insulating Performance: Completely non-magnetic and electrically insulated, no electromagnetic interference or current pitting damage, ideal for electronic, semiconductor and precision instrument equipment.
-
High Precision & Superb Polishability: Achieves mirror-level smooth surface with ultra-tight sphericity and dimensional tolerance, meeting G10-G100 high-precision grade standards for precision assembly.
