How to install imported high-speed precision angular contact ball bearings?

Imported high-speed precision angular contact ball bearings are mainly used for high-speed rotating occasions with light load,requiring bearings with high precision,high speed,low temperature rise and low vibration and certain service life.The supporting parts of high-speed motorized spindle are often installed in pairs and are the key accessories of high-speed motorized spindle of internal surface grinding machine.

Main technical indicators:

1.Bearing accuracy index: more than GB/307.1-94 P4 level accuracy

2.High-speed performance index:dmN value 1.3~1.8x 106 /min

3.Service life(average) :> 1500 h

The service life of high-speed precision angular contact ball bearings has a great relationship with the installation,and the following matters should be paid attention to：

1. Bearing installation should be carried out in a dust-free and clean room, bearings should be carefully selected, bearing spacers should be ground,under the premise of maintaining the height of the inner and outer spacers, the parallelism of the spacers should be controlled below 1um;

2. The bearing should be cleaned before installation,the inner ring slope is upward when cleaning, the hand sensor is flexible, no sense of stagnation,after drying,put specified amount of grease, such as oil mist lubrication should be put into a small amount of oil mist;

3.Special tools should be used for bearing installation,with uniform force and no beating.

4.Bearing storage should be clean and ventilated, no corrosive gas, relative humidity does not exceed 65%, long-term storage should be regular rust prevention.
