Full ceramic bearings constructed entirely of ceramic material. Inner/outer races and balls are made of either Silicon Nitride (Si3N4), Zirconium Oxide (ZrO2) or Silicon carbide (SiC). Full ceramic bearings are lighter, smoother, stiffer, harder, corrosion resistant, and electrically resistant. Full Ceramic bearings are used in extreme and in special environments like operating temperature from as low as -85°C up to + 800°C, vacuum environments, semiconductor manufacturing, non-magnetic equipment and more.
