High Precision Angular Contact Ball Bearings for Machine Tool Spindle

High precision angular contact ball bearings performance


ZYS angular contact ball bearings can bear radial load and one direction axial load. When the bearing withstands radial loads, axial force will be generated on inner ring. Therefore, the single-row angular contact ball bearings are often used with other bearings which can withstand axial load in the opposite direction. That is, angular contact ball bearings are commonly used in pair, or in groups with three, four and even five bearings.

1. Contact angles of ZYS angular contact ball bearings 
The contact angles of ZYS angular contact ball bearings for machine tool are 15° and 25°. The bearing with 15° contact angle is used when the high speed and light axial load are needed, while the 25° contact angle bearing should be adopted on the contrary.

2. Four dimension series of ZYS angular contact ball bearings 
The precision angular contact ball bearings for spindles have four dimension series, 718, 719, 70 and 72. With the same inner diameter, the outer diameter and the width of 718, 719, 70 and 72 increase in sequence.

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.
