High - speed precision angular contact ball bearing installation method

High - speed precision angular contact ball bearing installation method
    
High-speed precision angular contact ball bearings, mainly for low-load high-speed rotation occasions, requiring high precision bearings, high speed, low temperature vibration and a certain degree of service life. Often used as 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 / 307.1-94P4 level accuracy
    2. High-speed performance indicators: dmN value of 1.3 ~ 1.8x106 / min
    3. Service life (average):> 1500h
    High-speed precision angular contact ball bearing life and installation of a great relationship, should pay attention to the following:
    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 should be put into 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.
