Product details

1, by use: (1) , high-speed bearings: Ceramic bearings with cold resistance, stress elasticity, pressure resistance, thermal conductivity, light deadweight, small coefficient of friction and other advantages, can Be used in 12000 rpm/min-75000 RPM high-speed spindle and other high-precision equipment (2) , high-temperature bearing: the material itself has high temperature resistance 1200 °C, and good self-lubrication, use temperature between 100 °C-800 °C does not produce the expansion caused by temperature difference. Can Be used in furnace, plastic, steel and other high-temperature equipment; (3) , anti-corrosion bearing: the material itself has anti-corrosion characteristics, can be used in strong acid, strong Alkali, inorganic, organic salt, seawater and other fields, such as: electroplating equipment, electronic equipment, chemical Machinery, shipbuilding, medical equipment, etc. . (4) , anti-magnetic bearing: Because of non-magnetic non-dust absorption, can reduce the early spalling, noise and so on. Can Be used in degaussing equipment. Precision instruments and other fields. (5) electrical insulating bearings: Because of high resistance, can avoid arc damage bearings, can be used in various requirements of electrical equipment insulation. (6) , vacuum bearing: Because of the unique oil-free self-lubrication characteristics of ceramic materials, in the ultra-high vacuum environment, can overcome the common bearing can not realize the lubrication problem. Note: The same set of bearings can be used in high temperature, high speed, acid-base, magnetic field and non-insulation, but the material properties are different (please refer to the rare earth ceramic material performance table) , according to their application of the occasion, to choose the most suitable materials of ceramic bearings. 2, according to the material: Zirconia ceramic bearings all ceramic bearings with magnetic and electrical insulation, wear and corrosion resistance, no oil self-lubrication, high temperature and cold resistance, and other characteristics, can be used in extreme harsh environment and special conditions. The ferrule and roller are made of Zirconia (zro 2) ceramic material, the retainer is made of glass fiber reinforced Nylon 66(RPA66-25) , special engineering plastics (PEEK, Pi) , stainless steel (AISISUS316) , brass (Cu) , etc. . Silicon nitride ceramic bearing silicon nitride ceramic bearing rings and rollers using Silicon nitride (Si3N4) ceramic materials, the use of polytetrafluoroethylene retainer as a standard configuration, generally can also use RPA66-25, PEEK, Pi, as well as bakelite folder. Compared with ZRO2, SiN4-based all-ceramic bearings are suitable for higher speed and load capacity, as well as higher ambient temperature. At the same time, it can provide high-speed high-precision high-rigid spindle precision ceramic bearings, the highest manufacturing accuracy UP to p 4 to UP grade. Full-loaded ball bearing full-loaded ball full-loaded ball full-loaded ceramic bearing with a ball notch on one side, because of the use of cage-free structure design, more ceramic balls can be loaded than standard structure bearing, thus increasing its load capacity, in addition, the utility model can avoid the restriction of the cage material and achieve the corrosion resistance and temperature resistance effect of the ceramic cage full ceramic bearing. This series of bearings is not suitable for high speed, installation should pay attention to the notch surface installed in the end not bearing axial load. Ceramic Cage all-ceramic bearing ceramic cage has the advantages of wear resistance, high strength, corrosion resistance and self-lubrication. all-ceramic bearing made of ceramic cage can be used in harsh environments such as extremely strong corrosion, ultra-high low temperature and high vacuum. The commonly used ceramic materials are ZRO2, Si3N4 or SIC. The ceramic ball of hybrid ceramic ball bearing, especially silicon nitride ball, has the characteristics of low density, high hardness, low friction coefficient, wear resistance, self-lubrication and good rigidity, especially suitable for high-speed, high-precision and long-life Hybrid Ceramic Ball Bearings Rolling Body (inner and outer ring for Metal) . Generally, the inner and Outer Rings are made of bearing steel (GCR15) or stainless steel (AISI440C) , and the ceramic balls are made of ZRO2, Si3N4, or SIC. 3, according to the technical grade: (1) , deep groove ball bearing, ceramic bearing, ceramic bearing, drawing book bearing (Technical Grade: P4, P5, P6, P0) deep groove ball bearing, the most representative rolling bearing, widely used, can Bear radial load and two-way axial load. It is suitable for high speed rotation, low noise, low vibration or high temperature, cold, corrosion, magnetic field, non-insulation, etc. . (2) , self-aligning ball bearing, self-aligning ball bearing outer ring raceway is spherical, can supplement the error caused by different concentricity and shaft deflection. Used to produce different shaft and Shell or shaft flexure parts and high temperature, low temperature, corrosion, magnetic field non-insulation requirements of self-aligning parts. Note: The slope must not exceed 3 degrees. (3) single row angular contact ball bearings (technical grade: P 4, P 5, P 6, p 0) angular contact bearings are suitable for high-speed and high-precision rotation, in high temperature, magnetic field, water and so on does not affect its accuracy, and can bear synthetic load. The standard contact angle is 15 ° , 30 ° and 40 ° , the larger the contact angle is, the larger the axial load capacity is, and the smaller the contact angle is, the bearing can bear radial load and one-way axial load. The installation is usually done in pairs. Please pay attention when you buy. (4) the one-way thrust ball bearing, the one-way thrust ball bearing, is composed of the washer-shaped ferrule with the ball rolling track and the cage with the ball assembled. Can bear axial load, but can not bear radial load.
