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 and a lot installed, 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.
