Our aluminum guide rollers for mechanical equipment are available in a wide range of specifications and offer high strength and excellent durability. Each roller is finely machined using precision equipment and specialized cutting tools to achieve a smooth surface finish. The coaxiality is controlled within 0.02 mm, and the entire shaft is computer-balanced to within 2 g.

With specially engineered shaft ends and high-quality imported bearings, the rollers operate smoothly and effortlessly even at high speeds.

To meet the needs of different industries, various surface treatments are available, including sandblasting, engraved patterns, Teflon coating, and special hardening up to HV700, providing outstanding scratch and wear resistance. The term “guide roller” refers to a cylindrical component capable of rotating smoothly within machinery.

After approximately 15 days of operation, the aluminum guide rollers used on printing machines— including standard aluminum guide rollers and anilox aluminum rollers—experienced a sudden fracture around 260 mm from the shaft end. The breakage occurred with a loud noise, and the fractured shaft end was projected nearly one meter away.

The roller shaft is a variable-diameter shaft, with a maximum diameter of 545 mm and a total length of 2296 mm. It is made from 40Cr steel and manufactured through forging, rough machining, quenching and tempering heat treatment, and finish machining.

LEESUN aluminum guide rollers offer high strength, low rotational resistance, lightweight construction, smooth running, corrosion resistance, and excellent wear performance. They are particularly suitable for precision machinery in industries such as printing, packaging, plastics, electronics, and battery production, as well as various roll-to-roll material processing applications.
