Features:Theceramic rolling bearing is suitable to work in harsh condition of corrosive fluids, because ceramic is almost not afraid of corrosion.Dueto the lower density of ceramic rolling balls and much lighter weight than steel, the centrifugal effect to external race can be reduced by 40% when rotating, thus greatly extend the service life.Theceramic is less affected by thermal expansion than steel, therefore, when bearing clearance is certain, it can work in a environment where temperature changes more severely.Theelastic modulus of ceramic is higher than steel, so ceramic is not easyto deform under stress, which can improve work speed, and achieve a higher precision.Widelyused for medical apparatus and instruments, cryogenic engineering, optical instrument, high-speed machines, high-speed electric machinery, printing machinery, food processing machinery, aviation, spaceflight, navigation, petroleum, chemical industry, automobile, electronics, metallurgy, electric power, textile, pumps.Specification:Model: 695Inside Diameter: 5mm / 0.2inOuter Diameter: 13mm / 0.5inThickness: 4mm / 0.16inColor: WhiteType: 695 full ceramic bearingMaterial: Zirconia ceramicsRolling Element Row: Single rowRace Type: Deep groove raceWeight: 3g / 0.1oz (approx.)Package list:1 * Bearing
