   High-speed precision angular contact ball bearings, mainly for low-load high-speed rotating occasions, requiring high precision bearings, high speed, low temperature vibration and a certain degree of service life. Often used as a high-speed spindle support components used in pairs, is the surface of the high-speed spindle grinding machine key components. Main Specifications:
   1. Bearing accuracy indicators: more than GB / 307.1-94 P4 level accuracy
   2. High-speed performance indicators: dmN value of 1.3 ~ 1.8x 106 / min
   3. Service life (average):> 1500 h
   High-speed precision angular contact ball bearing life and installation of a great relationship, should pay attention to the following matters
   1. Bearing installation should be carried out in a clean, clean room, the bearings should be carefully selected, bearing with a ring to go through grinding, while maintaining the inner and outer ring spacing under the premise of the parallelism should be controlled in the 1um the following;
   2. The bearing should be cleaned before cleaning, cleaning the inner ring slope up, feel should be flexible, no stagnation, dry, put the prescribed amount of grease, if the oil mist lubrication should be placed in a small amount of oil mist oil;
   3. Bearing installation should be used special tools, uniform force, is strictly prohibited;
   4. Bearing storage should be clean and ventilated, no corrosive gas, relative humidity of not more than 65%, long-term storage should be regularly rust.
