Introduction of angular contact ball bearing:

Angular contact ball bearings have raceways in the inner and outer rings that are displaced 

with respect to each other in the direction of the bearing axis. This means that they are 

designed to accommodate combined loads, i. E. Simultaneously acting radial and axial loads. 

The axial load carrying capacity of angular contact ball bearings increases with increasing 

contact angle.

Ceramic ball especially silicon nitride ceramic ball have the following performance as low

density, high strength, low friction coeffecient, electrical and magnetism resistance, wear

resistance, well rigidity, lubrication and maintenance free when working, ceramic angular

contact ball bearing has the characteristics of high temperature resistance, cold resistance,

abrasion resistance, corrosion resistance and insulation, and can be used in extremely bad

environment and special conditions.it's the best choice for rollers and rings for bearing wich

are used in high speed, long accuracy and long life environments. So they are widely used in

aviation, aerospace, marine, petroleum, chemical, automotive, electronics, metallurgy, electric

power, textile, medical equipment and other fields.



The inside and outside rings are made by chrome steel (GCr15)/stainless steel/Silicon Nitride



The balls are made of silicon nitride ceramic/ZrO2;


The retainers are made by PEEK or PTFE.
