Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What materials are ceramic bearing balls made of? **A**: Common materials include silicon nitride (Si3N4), zirconia (ZrO2), and alumina (Al2O3). Each offers different properties: silicon nitride is known for high strength and thermal stability, zirconia for toughness, and alumina for cost-effectiveness. ### Q: What are the typical size ranges and grades? **A**: Diameters range from 1.588 to 50.8 mm, with grades from G5 to G100 per ISO 3290. Grade indicates sphericity and surface finish; lower numbers are higher precision. ### Q: How do ceramic balls compare to steel balls? **A**: Ceramic balls are lighter, harder, and more corrosion-resistant than steel. They also provide electrical insulation and can operate at higher temperatures. However, they are more brittle and may have higher initial cost. ### Q: What are the key parameters to verify before use? **A**: Verify diameter, grade, material type, hardness, roundness, density, compressive strength, fracture toughness, maximum operating temperature, electrical resistivity, surface roughness, and weight. Always confirm these with the manufacturer for your specific application. ## 6.
