Often pairs of high speed motorized spindle support installation and use, is the key to inner surface grinding machine spindle Kit. Main technical index: 

1. bearing precision: more than GB/307.1-94 P4 level accuracy 2. high performance: dmN 1.3~1.8X 3. the use of life expectancy (average): >1500 h Life and installation of high speed precision angular contact ball bearings have a great relationship, should be aware of the following 1. bearings should be installed in a dust-free, clean room, bearing carefully matching, bearing spacer after grinding, keep and outer ring spacer under the condition of high, intermediate ring parallelism should be controlled at less than 1um; 2. the bearing should be cleaned before installation, slope within cleaning up, feel should be flexible, with no sense of stagnation after drying, add weight oil, in the case of oil-mist lubrication oil mist should be put in a small amount of oil; 3. bearings are mounted using special tools, even by force, do not beat; 4. bearing storage should be clean and ventilation, no corrosive gases, relative humidity of not more than 65%, long-term care should be rust on a regular basis.
