What is rubber roller ? 

Structure of bearing and shaft head inside the rubber roller is very precise, and a slight difference will directly affect the use effect. If lubrication of bearing and shaft head is not very good, it's easy to cause wear and seriously affect the quality of rubber roller, which will affect product quality.

Rubber rollers are widely used in textile, printing and dyeing machinery (rolling roller, printing machine rubber roller, coating rubber roller, setting machine rubber roller etc.), paper making,Plastic printing, packaging, industrial, wood, glass, steel metallurgy, tobacco, transportation and other equipment

What are the silicone rubber materials?

1. NBR rubber roller:NBR rubber roller can be used as printing roller, food industry rubber roller, dyeing roller in textile printing in dustry and the soft rubber roller for contacting solvent and so on.
Note: The NBR has poor ozone resistance and the operation should be avoided in a high concentration ozone environment during processing.

2. Neoprene roller:Suitable for the soft printing roller, gravure printing roller and so on.

3. Silicone roller:High temperature resistance which can reach 200-250 degrees, and good chemical resistance,but it has low tensile strength.Silicone roller can be used in fabric heat setting, plastic heat setting embossing, calendering, photocopying and so on.

4.Polyurethane rubber:It has outstanding tensile strength wear resistance and crack resistance and good resistance to a variety of solvents.

5. Mirror roller:We generally adopt 45 # steel, alloy steel seamless pipe, precision forgings as the material.The surface of the roller finish degree can reach RA0.01. Mirror processing can ensure the roller surface flatness, balance, non-roundness, coaxial degree meet the customers’requirements.

Detailed material description of our rubber rollers

1) base Roller Material
We are using #45 steel , #201stainless steel #304stainless steel and 5# aluminum seamless pipe as the base roller.And we are adopting a reasonable thickness base roller according to customer’s drawing.Some manufacturers will reduce the thickness of the steel pipe in order to get the price advantage.Such roller can’t meet the standards.But we won’t do that.

2) Rubber Material
Our rubber are all imported from Germany or the US and then we mix them in our factory.The rubber coating technical we are using is winding technical. we cast the rubber on the base roller layer by layer and then vulcanize it to make the green rubber into mature rubber.While other manufacturers are using sheet coating technical,and the rubber is cold in processing and will cause adhesion problems easily.

As an experienced custom rubber roller manufacturer in China, we supply various rollers for different field.
