Mainly used, so far, in clear anodised aluminum, the new black guide roller from igus now supports packaging and labelling technology. The ready-to-install system consists of black anodised aluminium tubes and maintenance-free, smooth-running xiros polymer ball bearings.
Xiros polymer ball bearings are lubrication-free, maintenance-free and hygienic, and have a low breakaway torque. Due to these specifications, they are mainly deployed in the field of packaging and food technology. As fully assembled systems with a tube made of aluminium, carbon or polyvinyl chloride (PVC), the ball bearings are designed as guide rollers for deflecting films and labels or for conveying goods.
By using a wear-resistant polymers and thin-walled tubes, they provide a weight saving of up to 48% compared to metallic solutions, according to igus, which further claimed that the inertia is 42% lower, therefore the energy required for acceleration is “considerably lower” and the rollers reach the conveying speed faster.
The igus range has been expanded with a new black aluminium roller, which includes a black anodised aluminium for the roller and black xirodur S180 fixed flange ball bearings made of polymer. The new black roller also offers further areas of application, and is able to work with camera systems.
Igus has also developed the guide rollers expert for the selection of a suitable guide roller. In the online tool, the user 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 order the roller directly online.
