Inner diameter: 75 mm
Outer diameter: 105 mm
Thickness: 32 mm
Bearing series: angular contact ball bearings
Bearing Brand: NSK Bearings
Spot supply of imported INA bearings
   High-speed precision angular contact ball bearings, mainly for high-speed rotating light load situations requiring high precision bearings, high speed, low vibration, low temperature rise and a certain life. Often high-speed spindle bearing installed in pairs, is the inner surface of the high-speed spindle grinder key component parts. Main Specifications:
   1. Bearing precision index: more than GB / 307.1-94 P4 level precision
   2. High-speed performance: dmN value of 1.3 ~ 1.8x 106 / min
   3. life (average):> 1500 h
   High-speed precision angular contact ball bearing life of a great relationship with the installation, you should note the following
   1. Bearing installation should be in clean, clean a room, to go through carefully matching bearing, bearing spacer to go through the grind, while maintaining the inner and outer ring spacers high premise spacer parallelism should be controlled in 1um the following;
   2. The bearings should be cleaned before installation clean, cleaning the inner slope upward, feel should be flexible, no sense of stagnation, dried, placed in a predetermined amount of fat, in the case of oil mist lubrication should be placed in a small amount of oil mist;
   3. Bearing installation should use special tools, even by force, non-beat;
   4. Bearing storage should be clean and ventilated, non-corrosive gases, relative humidity less than 65%, long-term storage should be regularly rust.
   NSK Bearings acceptance inspection is usually divided into three categories, namely:

    General routine inspection routine inspection -NSK bearing arrive.
    Routine examination - of NSK Bearings and assembly-related dimensional accuracy, precision rotation, the bearing clearance and the residual magnetic intensity bearings and other items to be checked.
    Special inspection - quality of NSK bearing vibration and noise quality, and other special requirements of the bearing to be checked.
    With the advent of the tide of international, domestic and imported gradually bearing code bearing code standards, national standards for the latest edition of the display, the domestic code consistent with international ISO standards.
   We recommend the following models: 618 / 1320MA bearing RCJ30-N bearing 7014ADB bearing 6202-2Z bearings NJ2210 + HJ2210 bearing 7320BEGBY bearings GY1215-KRR-B-AS2 / V bearing 7204BDT bearing NUP2208ECM 71915CDB bearing bearing bearing NNCF4944CV
   I also recommend you 71915CDB bearing uses: reducer, imagesetters, glass machinery, single-stage pump, water jet cutting machine, force and deformation detector, rotor pump, high frequency welding machine, wear testing machine, pneumatic pumps, etc. use.
