Product Description :
ZrO2 Zirconia Ceramic Balls – G10 High Precision (Ø 0.8–25.4 mm) Upgrade your precision assemblies with these high-purity Zirconia (ZrO₂) ceramic solid balls. Manufactured to G10 precision grade (ISO 3290), they offer exceptional roundness, a polished mirror-like surface, and consistent dimensional tolerance. Lighter than steel yet tougher than most ceramics, they are the go-to choice for hybrid bearings, valves, pumps, lab equipment, and grinding/media applications where corrosion, magnetism, or lubrication is an issue .
✨ Key Features & Material Advantages
  • Material: Zirconium Dioxide (ZrO₂ / Y-TZP stabilized zirconia) – white, dense, inert ceramic .
  • Precision Grade: G10 (high-precision sphericity & diameter control; low surface roughness) .
  • High Hardness & Wear Resistance: Outperforms steel in abrasion resistance and retains dimensional stability under load .
  • Corrosion & Chemical Resistance: Excellent against acids, alkalis, moisture, and many aggressive media; won’t rust like steel .
  • Lightweight: Lower density than steel (≈6.0 g/cm³) → reduced centrifugal force & inertia in high-speed bearings .
  • Non-Magnetic & Electrically Insulating: Ideal for sensitive instruments, MRI/electronic environments, and where EMI or conductivity must be avoided .
  • Thermal & Dry-Run Capability: Good high-temperature stability and can run with minimal/no lubrication in many scenarios .
  • Smooth Polished Surface: Reduces friction and contamination risk in precision/clean environments .
📏 Size Range
Available diameters: 0.8 mm, 1 mm, 1.5 mm, 2 mm, 2.381 mm (3/32"), 2.778 mm, 3 mm, 3.175 mm (1/8"), 3.969 mm (5/32"), 4 mm, 4.763 mm, 5 mm, 5.556 mm, 6 mm, 6.35 mm (1/4"), 7 mm, 7.938 mm, 8 mm, 9.525 mm (3/8"), 10 mm, 11.112 mm, 12 mm, 12.7 mm (1/2"), 15 mm, 15.875 mm (5/8"), 16 mm, 19.05 mm (3/4"), 20 mm, 22.225 mm, 25 mm, 25.4 mm (1") and other metric/inch sizes in between (select from options/variations).
 
⚙️ Common Applications
  • Hybrid / full-ceramic ball bearings, high-speed spindles, skate/RC/hobby bearings.
