💡 What is a ceramic bearing ball used for in bicycle hubs and why choose Si3N4?

These high-strength ceramic balls improve hub life and smoothness.

- High hardness reduces wear in high-speed hub conditions - Excellent corrosion resistance for damp or wet environments - Low density helps reduce rotating mass and energy use - Works well with dry-lubrication designs in sealed ball bearing hubs
