Note

1. The specifications in the table are recommended for use, but we can also manufacture roll rings according to the drawings provided by customers.

2. The grooves of the roll rings can be designed and manufactured in accordance with the GB13788-2000 standard, or they can be customized based on customer requirements and marked in a specific way.

3. We can supply compatible tool steel systems to assist customers in modifying their mills and rolling processes.

Application requirement

1. Compact or knock-on roll rings are strictly prohibited.

2. When assembling the entire roll ring assembly, the bearing clearance should be on the tighter side.

3. The rotational accuracy of the entire assembly (including circular runout and end runout) should be maintained within ±0.05 mm.

4. The fit of the entire assembly and the roll rings should be a transitional fit, and the components should be securely fastened.

5. The roll rings should not be cooled using water or oil-water emulsions.

6. The joints of the pipes in the internal cooling system must be leak-proof, and it is recommended to avoid using internal cooling altogether.
