Full ceramic bearings can be run completely dry. They do not need lubrication to run. Ceramic is non-porous, unlike steel, as a result it is virtually frictionless. Because there is no heat buildup and virtually no friction, full ceramic bearings can be run completely dry. What are the advantages of ceramic balls? 1.Since ceramics are hardly corrosive, ceramic rolling bearings are suitable for operation under harsh conditions filled with corrosive media. 2.Since the density of the ceramic rolling ball is lower than that of the steel, the weight is much lighter, so the centrifugal effect of the outer ring can be reduced by 40% when rotating, and the service life is greatly ext
