ZYS High precision angular contact ball bearings

 Description

With over 60 years of bearing research and development technology and manufacturing experience, ZYS can provide all the different bearing types to meet the requirements of various industry applications. You can find ball bearing, roller bearing, precision bearing from China bearing manufacturer ZYS.

1. Contact angles

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

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. Advantages:

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.
