Spot supply of imported bearings NACHI
   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 accuracy indicators: more than GB / 307.1-94 P4-level accuracy
   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 contour 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 oil, oil mist lubrication should be placed in the case of a small amount of oil mist;
   3. Install bearing special tools should be used, 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.
