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 bearing temperature, generally bearing chamber outside temperature can be inferred that if the use of the hole can directly measure the temperature of the bearing outer ring, is more appropriate. Generally, the bearing with the bearing operating temperature slowly began to rise 1-2 hours to reach steady state. The normal temperature of the bearing due to heat capacity, heat capacity, speed and load of the machine and different. If the lubrication, install the appropriate department, the bearing temperature will be rapid-rise, there will be abnormal high temperature, when to stop running, take the necessary precautions.
We recommend the following models: 7321B / DB bearing S6301.2RSR.W203B bearings 32322-A-N11CA bearing 07087/07196-B bearings 99575 bearings NJ18 / 800ECMA bearing 7340B / DT bearings 2210-K-2RS-TVH-C3 + H310 Bearing 23224EASKMH2324 bearing 1307K bearing 7240CDF bearing
