Zirconia Ceramic Balls (ZrO₂): Precision Components for Demanding Bearing & Advanced Applications
Puwei's high-purity Zirconia (ZrO₂) Ceramic Balls are engineered for superior performance in extreme conditions. Combining exceptional mechanical strength, wear resistance, and electrical insulation, they are the optimal solution for industries where reliability, longevity, and precision are non-negotiable. Ideal for electronic packaging, high-frequency modules, and precision bearing systems.
Material & Physical Properties
Base Material: Zirconium Dioxide (ZrO₂) with 99.5% minimum purity. Key properties include a density of 5.9 g/cm³, hardness exceeding 1200 HV, compressive strength over 2000 MPa, and fracture toughness of 6-8 MPa·m¹/². The thermal expansion coefficient is 10.5×10⁻⁶/°C with a maximum operating temperature of 800°C.
Electrical & Surface Characteristics
These balls are completely non-magnetic and offer excellent electrical insulation, with resistivity greater than 10¹⁵ Ω·cm and dielectric strength of 15-20 kV/mm. Surface finish achieves Ra ≤ 0.012 μm, and sphericity meets Grade 5 or better per ISO 3290-1:2014.
Product Features & Competitive Advantages
Unmatched Durability & Performance
Our fine-grained zirconia microstructure provides fracture toughness and mechanical strength far superior to steel or plastic, ensuring reliable operation in high-load and high-vibration environments common in power devices and integrated circuit manufacturing.
Superior Corrosion & Wear Resistance
Resistant to chemicals, acids, and alkalis, these balls eliminate rust and degradation, extending component life in corrosive fluid handling systems and reducing total cost of ownership.
Critical Electrical Insulation
The non-magnetic and insulating properties make them essential for electrical isolation in sensitive microelectronics packaging, sensor packaging, and microwave components, preventing short circuits and signal interference.
Thermal Stability & Biocompatibility
Low thermal conductivity ensures consistent performance under thermal cycling. Their inert nature meets hygiene standards for medical, dental, and food processing applications.
Optimal Implementation Guide
- Selection & Sizing: Choose from our standard size range (0.5mm to 50mm) based on your load and spatial requirements.
- Compatibility Check: Verify material compatibility with adjacent components and operating media, especially in high-temperature or corrosive settings.
- Installation Preparation: Clean mating surfaces thoroughly and confirm dimensional tolerances to ensure a perfect fit.
- Lubrication Advisory: Use only compatible lubricants that do not react with ceramic surfaces to maintain performance.
- Performance Monitoring: Establish regular inspection schedules to monitor wear and optimize service intervals.
Application Scenarios
Precision Engineering & Electronics
Widely used in precision bearings, high-speed spindles, and linear guides. Their electrical insulation is critical for electronic packaging, high-frequency modules, and as insulation elements in integrated circuits and high-power microelectronic components.
Fluid Systems & Specialized Industries
Ideal for pumps, valves, and chemical reactors handling corrosive media. Also suited for medical devices, aerospace, and optoelectronics applications due to biocompatibility and stability.
Value Proposition for Business
- Extended Service Life: 3-5x longer lifespan than steel balls, reducing replacement frequency and downtime.
- Operational Efficiency: Lower friction coefficients decrease energy consumption in rotating equipment.
- Cost Reduction: Minimal maintenance and no corrosion-related failures lower total cost of ownership.
- Performance Reliability: Consistent operation across extreme temperatures and harsh environments enhances product integrity.
