The drylin bearings from igus prove their worth in linear drives that have to operate highly dynamically under heavy loads. Dry-operating drylin linear guides with iglidur liners ensure the precise guidance of the axes, which have diameters of 30 to 50 mm, which are ideally suited for the given conditions. The drylin pillow block bearings are also used in other plants in combination with hardened steel shafts. This is not the optimum friction combination recommended by igus, but it offers a significantly longer service life in this application. 4.5 million working cycles under unfavourable conditions. In Krenzer's experience, these linear guides have a service life of around three months. That doesn't seem like much at first. However, if you multiply 50,000 strokes by 90 days, this results in 4.5 million working cycles and that with dirt, high dynamics and alternating loads. And, most importantly: With other types of bearing arrangement, such as ball bushings and recirculating ball bearing guides, which Krenzer had experimentally used in other plants under similar conditions, the service life is even shorter. In addition, the guides operate maintenance-free under the unfavourable environmental conditions, and Krenzer is also very satisfied with the precision that the drylin axes achieve.
