High speed precision angular contact ball bearing, mainly used for high speed rotating load lighter, bearings and high precision, high speed, low temperature rise, low vibration and service life. Often for high speed motorized spindle bearing parts installed in pairs, is the key to the high-speed motorized spindle surface grinding machine fittings.
The main technical indicators:
1. The bearing precision index: more than GB / 307.1 94 P4 level precision
2. High speed performance indicators: dmN value 1.3 ~ 1.3 x 106 / min
3. The service life (on average) : > 1500 h
High speed precision angular contact ball bearing service life had a lot to do with the installation, the following should be paid attention to
1. The bearing installation should be clean, clean room, bearing should be carefully selected, bearing with baffle passes through grinding, and in keeping the baffle on inner and outer contour under the premise of baffle parallelism should be controlled below 1 um.
2. Bearing should be cleaned before installed and when cleaning inner ring ramp up, flexible hand induction, no stagnation, air-dried, into the specified amount oil, if oil mist lubrication oil should be in a small amount of oil mist.
