Note

1. The table specifications are recommended guidelines; however, we also manufacture roll rings to customer-provided drawings.

2. Roll ring grooves can be designed and manufactured to comply with the GB13788-2000 standard or customized according to customer requirements, including specific marking.

3. We supply compatible tool steel systems to support customer mill and rolling process modifications.

2) Application Requirements

a. Compact/Knock-on roll rings are strictly prohibited.

b. During assembly of the roll ring unit, maintain bearing clearance on the tighter side.

c. Rotational accuracy (radial and axial runout) of the fully assembled unit must be maintained within ±0.05 mm.

d. The interface between the roll rings and the assembly components must be a transitional/interference fit, with all components securely fastened.

e. Roll rings must not be cooled using water or oil-water emulsions.

f. Internal cooling system pipe joints must be leak-proof. We strongly recommend avoiding internal cooling systems altogether.
