Black guide roller with smooth-running polymer ball bearings saves up to 48 per cent weight and 42 per cent mass inertia They divert films or labels: guide rollers with ball bearings. Mainly used, so far, in clear anodised aluminium, the new black guide roller from igus now provides a real sensation in packaging and labelling technology. <\/p>\n\n\n\n
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. <\/p>\n\n\n\n
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 per cent compared to metallic solutions. Their mass inertia is 42 per cent lower, and therefore the energy required for acceleration is considerably lower and the rollers reach the conveying speed faster. <\/p>\n\n\n\n
The igus range has now been expanded with a new black aluminium roller. \u201cThe 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 de- sired for one labelling series\u201d, explains Marcus Semsroth, Head of the xiros polymer ball bearing division at igus GmbH. <\/p>\n\n\n\n
The solution: black anodised aluminium for the roller and black xirodur S180 fixed flange ball bearings made of polymer. \u201cThis soon resulted in a product that met the customer\u2019s requirements in terms of technology, price and appearance\u201d, 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 cam- era systems, as it doesn\u2019t reflect light. <\/p>\n\n\n\n
