I-ring and rolling body of ceramic bearing yenziwe ngezixhobo zonke ze-ceramic, kuquka i-zirconia (ZrO2), i-silicon nitride (Si3N4) kunye ne-silicon carbide (Sic). I-retainer yenziwe nge-polytetrafluoroethylene, i-nylon 66, i-polyetherimide, i-zirconia, i-silicon nitride, insimbi engenasici okanye i-aluminium ekhethekileyo ye-aviation, ngaloo ndlela yandisa indawo yokusetyenziswa kweebheringi ze-ceramic.
