Full Ceramic Ball Bearings

Full ceramic bearings have the characteristics of non-magnetic electrical insulation, wear resistance, corrosion resistance, oil-free self-lubrication, high temperature resistance, low temperature resistance, etc., and can be used for extreme evil and special working conditions.

NBVO's full ceramic ball 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). They are available as full complement (no cage) or with a cage made from PEEK or PTFE. Full ceramic bearings are for medium load and medium speed applications. It is not possible to achieve the inner and outer ring roundness that is found with precision steel bearings so full ceramic bearings have lower speed ratings.
