1.5mm Alumina Ceramic Ball for High-Precision Bearings
✔️ 1.5 mm diameter loose ceramic ball in Al2O3, single unit

A single loose ceramic ball made from alumina oxide (Al2O3), 1.5 mm in diameter. This ceramic ball is a common choice for bicycle bearings and small precision mechanisms where low friction, high hardness, and corrosion resistance matter.

✅ Size: 1.5 mm diameter
✅ Material: Al2O3 ceramic (alumina oxide)
✅ Form: Loose ball, single unit
✅ Typical uses: bicycle components and precision mechanisms

💡 What is a ceramic bearing ball used for in precision mechanisms? This handy overview explains its role in bearings and assemblies.
- low friction operation in micro bearings and bicycle parts
- high hardness and corrosion resistance from alumina oxide
- stable performance in tight tolerances and small races
- lightweight alternative to steel balls in compact assemblies
