10pcs Ceramic Ball 1.588/2.0/2.381/2.5/2.778/3.0/3.175/3.5/3.969 Zirconia Ceramic Ball ZrO2 (Outer Diameter : 3.0mm)

10-Piece Zirconia Ceramic Ball Set (ZrO2) in Mixed Diameters: 1.588 to 3.969 mm OD
✔️ 10 pcs mixed diameters zirconia ceramic balls (ZrO2) for bearings, 1.588 to 3.969 mm OD

These zirconia ceramic balls are designed for high-load bearings and precise motion, and are commonly used in sealed ball bearing assemblies, linear slides, and instrument stages. The 10-piece set spans multiple outer diameters from 1.588 mm to 3.969 mm for flexible fitting in varied assemblies. Zirconia (ZrO2) balls offer high strength and toughness at room temperature, excellent wear resistance, high rigidity, non-magnetic properties, and electrical insulation. They maintain density near 6.00 g/cm3 at 600°C and have a thermal expansion rate close to metal, enabling use with metal components.
