Rubber Rolls

Rubber rolls for steel products and paper manufacturing are used under adverse conditions involving loads, heat, chemicals, and oils.
At our company, we have earned a high degree of trust from users through our unique methods, such as rubber compounding techniques, molding methods, and vulcanizing methods.
We provide various types of rubber rolls, such as ringer rolls, bridle rolls, and sink rolls, that are used in cold rolling lines at iron mills. Our company’s strengths include the ability to provide reliable products with few internal flaws through the joint use of ribbon molding machines and high pressure heated water vulcanization.
The revolutionary AW series is an excellent rubber material that can be used even under adverse conditions, with chemical resistance, abrasion resistance, and oil resistance that exceed previous materials.

Main Usages of Rubber Rolls

Ringer rolls, bridle rolls, deflector rolls, dam rolls, pinch rolls, support rolls, etc.

Our company’s rubber rolls are mainly used in cold rolling lines at iron mills.
Cold rolling lines at iron mills consecutively acid clean, degrease, anneal, and plate coils. Rubber rolls are used at various points of these lines to pull iron plates, squeeze out liquids, and change directions. Our company’s rubber rolls are also used at paper manufacturing factories.
