Full ceramic thrust bearings with zirconia oxide or silicon nitride rings and ceramic balls is designed to handle thrust loads environments that are too hostile for steel bearings. They are non-magnetic, have good to excellent corrosion resistance depending on the material and the chemicals encountered and are normally supplied without lubrication. Full ceramic bearings may have PTFE or PEEK retainers or be supplied as full complement (without a retainer). They can be used in very high temperatures if supplied as full complement.
