Stainless Rolling Element/Chrome Bearing Steel Balls/ Carbon Steel Balls 
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.
| Manufacture process of steel balls | ||||
| Step 1 Heading | Balls blanks are cold headed from rolls of wire. | |||
| Step 2 Flashing | Rolling balls between two hard alloy plates to removes the slight band and small protrusions. |
|||
| Step 3 Heat treat | Heating balls to a high temperature in furnace and quenching balls in a liquid bath. | |||
| Step 4 Rough grind | Rolling balls between the face of a fixed iron plate and a very hard fire-grit grinding wheel. Then rolled the hardened ground balls between two cast iron plates. | |||
| Step 5 Cleaning | The final production operation cleans the finished balls and adds a shiny luster. | |||
| Step 6 Final Inspection |
Balls are gauged, visually inspected and subjected to other quality tests to insure every customer's specifications are achieved. |
|||
| Step 7 Packaging | The balls are packaged in accordance with customer specifications for shipping. | |||
