Building on the benefits of polymer linear bearings

Igus is continually developing its range of linear products, with a good example being the Drylin W family. The modular system consisting of anodised aluminium, die-cast zinc housings and plastic plain bearings enable the best possible use of space. Guide rail widths of between 40 and 80mm allow many different combinations to be used with carriage lengths of 100, 150 and 200mm. There are new sizes and variants, too. As well as the size 20 system designed for high loads, Igus has a new carriage design, fitted onto anodised aluminium double rails or a single, flexible rail. The DryLin WQ can better compensate for differences of height in the mounting faces. The square-shaped design - unlike a round shaft - ensures that the loads are evenly distributed for better results. Due to the flat supporting surface, the friction value of the guide is reduced by 15 percent compared to the standard DryLin W guide. In addition, the friction value (-20 percent) and wear (-34 percent) are optimised by the use of a new plain bearing material. The overwhelming robustness of the new square-shaped solution is clear. Large supporting surfaces distribute the load evenly and can therefore be used in applications that have a high surface pressure. Users are also able to reduce installation costs: the multi-axis movement (+/-1mm) of the ‘floating bearings’ compensates for alignment and parallelism errors between the rails. Jamming, which can only otherwise be prevented by time-consuming alignment of the rails, can thus be ruled out.
