3. Application of ZYS angular contact ball bearings :
•Machine tool spindle
•high-frequency motor
•Robot technology
•gas turbine
•centrifuge
•small-size automobile front wheels
•differential pinion shaft

4. Advantages of ZYS angular contact ball bearings :
As an important type of  machine tool bearing, ZYS angular contact ball bearing has the following advantages:

The chamfer arc radius of rings is reasonable, which is not only convenient to install, but also guaranteed to improve the installation precision and reduce the risk of the related parts being bumped;

•The speed performance is outstanding
•Unique heat treatment process allows products to achieve the best dimensional stability and rigidity, so as to reduce wear and tear;
•Multiple pre-load levels can help to meet different requirements for speed and system stiffness, which is more reasonable to select and use the levels.
