Fast and lubrication-free: new xiros film guide roller for labelling technology
Black guide roller with smooth-running polymer ball bearings from Treotham saves up to 48% weight and 42% mass inertia
They divert films or labels: guide rollers with ball bearings. Mainly used, so far, in clear anodised aluminium, the new black igus guide roller from Treotham now provides a real sensation in packaging and labelling technology. The ready-to-install system is convincing not only visually, but also technically. It consists of black anodised aluminium tubes and maintenance-free, smooth-running xiros polymer ball bearings.
xiros polymer ball bearings are lubrication-free, maintenance-free, hygienic and have a very low breakaway torque. Due to these specifications, they are mainly used in the field of packaging and food technology. As fully assembled systems with a tube made of aluminium, carbon or PVC, the ball bearings prove their worth as guide rollers for deflecting films and labels or for conveying goods. By using wear-resistant high-performance polymers and thin-walled tubes, they provide a weight saving of up to 48% compared to metallic solutions. Their mass inertia is 42% lower, and therefore the energy required for acceleration is considerably lower and the rollers reach the conveying speed faster. The igus range has now been expanded with a new black aluminium roller. "The idea for the black design arose from a customer enquiry. The technical specifications of our classic aluminium rollers were already very convincing, but black visible parts were desired for one labelling series", explains Marcus Semsroth, Head of the xiros polymer ball bearing division at igus GmbH. The solution: black anodised aluminium for the roller and black xirodur S180 fixed flange ball bearings made of polymer. "This soon resulted in a product that met the customer's requirements in terms of technology, price and appearance", says Semsroth. In addition to this, the new black roller also offers further areas of application. This allows the roller to work easily together with camera systems, as it doesn't reflect light.
Custom guide roller configured in two steps
igus has developed the guide rollers expert for the quick selection of a suitable guide roller. In the online tool, the user only has to specify the outer and inner diameter as well as the length of the roller, the load, the load case and the ambient temperature. By entering the acting force and the degree of wrap around, the online expert calculates the resulting force on the roller and recommends the appropriate tube materials. In the second step, the user can select their guide roller based on the deflection, weight and price data, download the configuration CAD data and then order the roller directly from Treotham.
