Description Full ceramic bearing introduction:      Full ceramic bearings have the characteristics of anti-magnetic insulation, abrasion resistant, oil-free self-lubricating and enduring extreme high or low temperature, so they can be used for harsh environment and even under some special condition. The material of rings and rollers is jar gonia(ZrO2) and the holder uses poly back fluoride(PTFE) as standard configuration. Generally, we can use the reinforced nylon made of glass fiber 66(GRPA66-25), special engineering plastics (PEEK, PI), nonrust steel(AISI SUS316 SUS304), brass(Cu) and so on. Ceramic deep groove ball bearings are made entirely of ceramic material and are superior to common Steel Angular Contact Bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM’s, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present.  The advantages of ceramic deep groove ball bearing: 1) The ceramic bearing has the feature of corrosion resistance, the ceramic rolling bearing suitable for operation under harsh conditions covered corrosion media.  2) Since the ceramic ball rolling has lower density than steel, so which is much lighter, so when you rotate the outer ring centrifugal effect can be reduced by 40% , thus greatly extended service life. 3) The expansion and contraction of the ceramic affected smaller than steel, and therefore the gap of the bearing is constant, the bearing allows the temperature changes more severe environment. 4) As the ceramic has higher modulus of elasticity than steel, when the force is not easy deformation, and therefore help to improve the operating speed and achieve high accuracy.Related Models Bearing No Size Mounting Dimensions(mm) N.W N.W mm da da Da ra (kg) (refer) d D B min max max max ZrO2 Si3N4 6800CE 10 19 5 12 12 17 0.3 0.004 0.0021 6900CE   22 6 12 12.5 20 0.3 0.007 0.0038 6000CE   26 8 12 13 24 0.3 0.014 0.0075 6200CE   30 9 14 16 26 0.6 0.025 0.013 6300CE   35 11 14 16.5 31 0.6 0.04 0.022 6801CE 12 21 5 14 14 19 0.3 0.005 0.0025 6901CE   24 6 14 14.5 22 0.3 0.008 0.0042 16001CE   28 7 14 / 26 0.3 0.015 0.0079 6001CE   28 8 14 15.5 26 0.3 0.017 0.0092 6201CE   32 10 16 17 28 0.6 0.028 0.015 6301CE   37 12 17 18 32 1 0.046 0.025 6802CE 15 24 5 17 17 22 0.3 0.005 0.0029 6902CE   28 7 17 17 26 0.3 0.012 0.0063 16002CE   32 8 17 / 30 0.3 0.021 0.011 6002CE   32 9 17 19 30 0.3 0.024 0.013 6202CE   35 11 19 20.5 31 0.3 0.035 0.019 6302CE   42 13 20 22.5 37 1 0.064 0.035 6803CE 17 26 5 19 19 24 0.3 0.005 0.0029 6903CE   30 7 19 19.5 28 0.3 0.013 0.0071 16003CE   35 8 19 / 33 0.3 0.025 0.014 6003CE   35 10 19 21.5 33 0.3 0.032 0.017 6203CE   40 12 21 23.5 36 0.6 0.052 0.028 6303CE   47 14 22 25.5 42 1 0.087 0.047 6403CE   62 17 23.5 / 55.5 1 0.21 0.11 6804CE 20 32 7 22 22.5 30 0.3 0.013 0.007 6904CE   37 9 22 24 35 0.3 0.028 0.015 16004CE   42 8 22 / 40 0.3 0.037 0.02 6004CE   42 12 24 25.5 38 0.6 0.052 0.028 6204CE   47 14 25 26.5 42 1 0.082 0.045 6304CE   52 15 26.5 28 45.5 1 0.11 0.06 6404CE   72 19 26.5 / 65.5 1 0.31 0.17 6805CE 25 37 7 27 27 35 0.3 0.016 0.009 6905CE   42 9 27 28.5 40 0.3 0.032 0.018 16005CE   47 8 27 / 45 0.3 0.045 0.025 6005CE   47 12 29 30 43 0.6 0.061 0.033 6205CE   52 15 30 32 47 1 0.099 0.054 6305CE   62 17 31.5 36 55.5 1 0.18 0.098 6405CE   80 21 33 / 72 1.5 0.41 0.22 6806CE 30 42 7 32 32 50 1 0.018 0.01 Our Main Product
