    High-speed angular contact ball bearings, mainly for the load lighter, high-speed rotating occasions, requiring bearing high-precision, high speed, low temperature rise low vibration and the life of. Often for high-speed electric spindle bearing installed in pairs, the key component parts of the inner surface of the grinding machine of high speed electric spindle. slewing bearing manufacturers

    The main technical indicators:
    A bearing accuracy of indicators: more than GB/307.1-94 P4 level precision
    (2) high-speed performance: dmN value of 1.3 to 1.8x 106 / min.
    (3) life (average):> 1500 h

    High-speed angular contact ball bearing service life and a great relationship, should note the following:
    A bearing installation should be clean, clean room, bearing carefully matching, bearing with every lap to go through the grind, the premise of maintaining the level of inside and outside the ring spacers, spacer parallelism should be controlled in 1um the follow ing; slewing bearing suppliers
    Clean. Bearings should be cleaned before installation, cleaning inner slopes upward, should be flexible and feel a sense of stagnation, dried, placed in a specified amount of grease, such as in the case of oil mist lubrication should be placed in a small amount of oil mist of oil;
    Bearing installation should be used specialized tools, even by force, is strictly prohibited to beat;
    Bearings shall be stored in clean air, corrosive gases, no more than 65% relative humidity, long-term storage should be periodically rust-proof. slewing bearing
