Bearings featuring ceramic rolling elements are classified as hybrid ceramic ball bearings.
Ceramic bearings fall into two main categories: full ceramic bearings and hybrid ceramic bearings. In full ceramic bearings, both the rings and the rolling elements are made of ceramic material, whereas in hybrid ceramic bearings, only the rolling elements are ceramic.
The most widely used type of hybrid ceramic bearing is the ceramic ball bearing (featuring ceramic balls); these can be further categorized into zirconia ceramic ball bearings and silicon nitride ceramic ball bearings.
