DIN 2391, EN 10305-1, E355+N(SR), hard chrome-plated outside 25 +/-5 µm, fit f7 Dimensional range: Outer diameter 12,0 - 140 mm

As per the norm EN 10297 specifies the technical delivery conditions for seamless round steel tubes. The tubes for mechanical applications are mainly used in those processes in which turning and CNC machines are used. The wide size range available, with OD from 21.3 to 812 mm, gives the possibility to manufacture several kinds of components for different applications: small machine parts, flanges, fittings, Archimedean screws, hydraulic cylinders for heavy machines etc.

For a few years now seamless polyimide belts have been used in toner fusing for desktop printers and multifunctional printers. The most important advantages compared to using traditional steel or aluminum cores are: significantly shorter times lead to reach run temperatures major improvements in energy efficiency weight-saving and lower logistic costs flexible belts enable higher print speed and resolutions by allowing a wider fusing nip for both b&amp;w and color applications For these applications KB RollerTech developed a special coating process and produces seamless belts under clean room conditions. Different thermal and electrical properties of these belts can be precisely adjusted by adding special fillers. Today, the following dimensions are possible: Diameter: 20 - 310 mm Length: < 700 mm Wall thickness: 25 - 150 µm For the subsequent coating with anti-adhesive materials two alternative processes are used: Spray coatings with fluoro-polymers and subsequent sintering Coat
