Aluminum guide rollers, also known as aluminum alloy guide rollers, are manufactured from high-quality aluminum alloy (6063-T5). They are extruded into tubular shapes through precision molds and are available in a wide range of specifications with outer diameters from 30 mm to 220 mm. The internal reinforcing rib structure provides excellent strength and durability.
Each roller is finely machined using advanced equipment and specialized cutting tools to achieve a smooth surface finish. The coaxiality is controlled within 0.02 mm, and the entire shaft undergoes computer dynamic balancing with an accuracy within 2 g. With specially engineered shaft ends and high-quality imported bearings, the rollers operate smoothly and effortlessly even under high-speed conditions.
To meet the requirements of different industries, additional surface treatments are available, including sandblasting, engraved patterns, Teflon coating, and special hardening up to HV700, providing outstanding scratch and wear resistance.
Aluminum guide rollers feature high strength, low resistance, lightweight construction, smooth rotation, and excellent resistance to rust, wear, and corrosion. They are particularly suitable for precision machinery used in the printing, packaging, plastics, electronics, and battery industries, as well as various roll-to-roll processing applications.
Aluminum guide rollers offer multiple functions and are commonly used for guiding and conveying fabrics, webs, or non-woven materials that are exposed to heat, moisture, or mechanical stress. The guide roller assembly is typically equipped with a cover on the right side, and steam is introduced through a dedicated steam channel into the hollow shaft of the roller.
A short hollow shaft is used to maintain steam circulation and is securely connected to the end cap, forming a stable steam-delivery structure. Our guide rollers are supported by inner and outer ring bearings, ensuring precise alignment between the roller shaft and the hollow tube structure. Steam and air flow through the internal cavity of the roller, and are directed to the web surface through axial grooves or nozzles, enabling efficient and stable thermal processing and web guidance. This design is particularly suitable for guiding mesh fabrics, non-woven materials, and various roll-to-roll processing applications.
