Ceramic bearings cover rolling-element assemblies in which balls or races are fabricated from advanced technical ceramics — principally silicon nitride (Si₃N₄), silicon carbide (SiC), or zirconia (ZrO₂) — offering high hardness, low density, electrical insulation, and corrosion resistance; hybrid configurations pair ceramic rolling elements with steel races, while full-ceramic designs employ hot isostatic pressing (HIP) or sintering to achieve the required material density and surface finish.
