Nomex felt roller tube is a specialized industrial material used to protect roller shafts and aluminum profiles in aluminum extrusion lines. Made from heat-resistant Aramid fibers, this roller shaft felt tube is suitable for positions where rollers come into contact with hot aluminum profiles after the extrusion and cooling processes. Depending on the shaft dimensions and production line requirements, the felt tube is available in various thicknesses, inside diameters, and lengths.

What Is a Nomex Felt Roller Tube?

Nomex felt roller tube is a specialized material used to cover and protect roller shafts in industrial production lines, particularly aluminum extrusion lines. The product is made from 100% Nomex (Aramid) felt fibers imported from overseas and manufactured using a needle-punching process.

Thanks to its strong felt structure and the heat resistance of Aramid fibers, the Nomex felt tube forms a protective layer around the roller shaft. It is suitable for high-temperature working areas where material stability is required during operation.

Technical Specifications of Nomex Felt Roller Tube

  • Material: 100% Nomex (Aramid) fibers, manufactured using a needle-punching process to create a strong and uniform felt structure.
  • Continuous operating temperature: Approximately 250°C.
  • Maximum peak temperature: Up to 300°C for short periods.
  • Color: Off White.
  • Thickness: 6 mm, 8 mm, 10 mm, and 12 mm.
  • Inside diameter: From Φ23 to Φ120 mm, with common sizes including Φ25, Φ50, Φ60, Φ80, Φ90, Φ100, and Φ120 mm, or customized according to the roller shaft dimensions.
  • Length: Cut according to the actual dimensions and requirements of each production line.

Advantages of Nomex Felt Roller Tube

  • Protects aluminum surfaces: Creates a soft cushioning layer between the roller shaft and aluminum profiles, helping reduce scratches, surface damage, deformation, dents, and metal particles adhering to the aluminum surface.
  • Suitable for high-quality aluminum profiles: Particularly suitable for aluminum extrusion lines where a high-quality surface finish is required, such as polished or electrophoretic aluminum profiles.
  • Strong and durable structure: Nomex felt has a stable structure and relatively smooth surface, helping the tube maintain its shape during operation while reducing the risk of tearing, misalignment, or delamination.
  • Suitable for high-temperature environments: The heat resistance of Aramid fibers makes the felt tube suitable for roller shafts operating in aluminum extrusion and processing lines with elevated temperatures.

Applications of Nomex Felt Roller Tube

Nomex felt roller tubes are primarily used in aluminum extrusion lines, especially at positions where roller shafts require protective covering and operate at relatively high temperatures.

  • Run Out Table: Installed over roller shafts to support and transport aluminum profiles after extrusion.
  • Middle Temperature Zone: Suitable for positions where aluminum profiles remain hot after passing through the cooling section.
  • Walking Beam System: Used as a protective covering on contact and conveying points within the aluminum extrusion line.

The product is particularly suitable for production lines handling large or irregularly shaped aluminum profiles. After passing through the cooling table, some profiles may still retain high temperatures, making conventional Polyester materials potentially unsuitable for the required operating conditions. In such applications, Nomex felt tubes, with their higher heat resistance, can be used to cover roller shafts while helping minimize surface damage to aluminum profiles during transportation.
