Rubber rollers, also called "rubber rolls," are cylindrical tubes used to facilitate movement to machine components. Rubber rollers also provide support and transportation to materials moving through the machine. Rubber roller manufacturers produce rubber rollers that vary widely in size, ranging from one inch to several inches in length. Width also varies. Rubber rollers are often formed with the vulcanized molded process that uses heat and pressure to cure the rubber. The rubber is then bonded to the core.

Rubber rollers are common components of many different types of machinery, including web machines, converters, roller conveyor systems and printing machines. Process rollers alter roller systems by providing directional changes and changing power transmission levels. Unlike process rolls, idler rolls do not alter the rollers systems but simply provide support and the means of transportation of materials. Rubber rollers are used in photocopiers, laser printers, photographic imaging and printing presses. The medical industry uses rubber rollers in medical chart recorders and medical imaging equipment. Rubber rollers are also used in mailrooms for high-speed mail sorting. Other rubber rollers include film and microfilm rollers and magnetic tape capstans. Elastomeric rubber rollers include application or dispensing, squeegee, transfer, energy-absorbing and drive rollers.

Rubber roller manufacturers use a variety of rubber materials. Neoprene is a general purpose material that has good mechanical properties, chemical resistance and high resilience. Nip rolls, pull rolls and feed rolls in flexo and gravure printing machines are typically made of neoprene. Nitrile, also known as “NBR” or “Buna-N,” is the most commonly used elastomer in the printing industry, as it is exceptionally resistant to oils, chemicals and water. Silicone is a fairly expensive covering material that has good high temperature, chemical and ozone resistance. Certain rubber roller manufacturers coat rubber rollers with EPDM (sometimes referred to as “EPT”), because it has excellent ozone, chemical and heat resistance up to 350ºF (176.7ºC). Polyurethane has high-friction characteristics and is used in applications in which toughness and cut resistance are necessary (e.g. pull rolls). Hypalon has good physical, chemical resistive and temperature capabilities, as well as excellent ozone characteristics, making it ideal for a wide variety of roller applications. Viton is a very expensive material used for its excellent chemical resistance and high temperature characteristics.

The proper selection of rubber rollers depends on several important factors, including industrial applications, machinery size and product shape, size and weight. Environmental conditions, such as temperature and moisture, to which the rubber rollers will be exposed during operation, must also be considered. Substances, such as chemicals, oils and acids, with which the rubber rollers might come into contact, must also be considered before determining the appropriate type of roller. The outside diameter and runout tolerances, surface finish, hub material and amount of tackiness are characteristics that one should be aware of when designing rollers, especially clean rubber rollers. It is critical to understand how the physical properties of rubber rollers compare to the actual operating conditions and to keep up to date on improvements in roller technology. This knowledge allows for improvement of the equipment performance and end-product quality.

 

Paper Mill Rollers
Our compounds can stand up to the harsh environmental operating conditions where roller applications include breast, guide, wire return, couch, press, felt and touch roll positions. Higher durometers extend wear ability and roller life expectancy.
Lamination Rollers
We offer you a variety of products that provide longer service life and less downtime. Our rollers are built to provide a flawless roller finish for defect free laminating or embossing. We hold an industry wide reputation for quality, innovation, dependability, and superior value. Put a world class roller partner to work on your business!

Textile machinery Rollers
Many rolls like Jiger,Mangle,ebonite guide rolls etc.are a part of textile m/c. We make them all.

Special services are available on items to suit your needs.
Here are a few of the roller types we manufacture:
  • Printing Rolls
  • Form Rolls
  • Feeder Rolls
  • Glue Spreader Rolls
  • Sander Rolls
  • Waxing Rolls
  • Washer Rolls
  • Paper Mill Rolls
  • Wheels and Pulleys
  • Inking Rolls
  • Water Rolls
  • Nip Rolls
  • Coater Rolls
  • Drive Rolls  
  • Dryer Rolls
Common uses for rubber rollers are found in the manufacturing processes of textiles, paper, film, sheet and coiled metal. All sorts of container and packaging fabricating equipment as well as machinery used for the sanding and grinding of wood, steel and aluminum use rubber covered rollers. Covered rolls are used extensively in the graphic arts industry.

Rubber compounds for roll coverings include Silicone, Neoprene, Hypalon, Polyurethane, Buna Nitrile, Natural Rubber, Thiokol, Viton and EPDM.

The choice of covering material and the duro (hardness) is determined by the roller's environment and function.
