4.Angular contact ball bearing 7214 type:
Angular contact ball bearings are: 7000 c (∝ = 15 °) and 7000 ac type (∝ = 25 °) and 7000 b (∝ = 40 °) several types.

5.Bearing 7214 Installation techniques
High speed precision angular contact ball bearing 7207, 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.
Main technical indicators:
1. The bearing precision index: more than GB / 307.1 94 P4 level accuracy
2. High speed performance indicators: the dmN value 1.3 ~ 1.8 x 106 / min
3. The service life of the (average) : > 1500 h
