Brief Introduction of bearing ball                                                          

   ZYS has applied special technology to steel ball production,such as cold treatment, quadratic stable treatment, 100% AVIKO eddy current inspection.
The followings are our main steel ball products: 
1. ZGCr15 high carbon chrome steel balls: have better performance than GCr15
2. 9Cr18, 9Cr18Mo high carbon chrome stainless steel balls: the properties and
    applications of 9Cr18Mo and 9Cr18 are almost the same, but 9Cr18Mo is harder and
    temper resistant after quenching.
3. Cr4Mo4V high temperature steel balls: especially for aero engine bearings and
    bearings working in high temperatures below 316ºC with DN 2.6 ×106 more or less. 
4. Other steel balls with special materials.
We also have ceramic balls and carbide balls.
