Warranty statements are often associated in the plant with considerable risks. With our unique igus® guarantee for ALL chainflex® cables we provide predictable reliability for 36 months or up to 10 million double strokes (or 5 million double strokes for the very cost-effective chainflex® M cables). For over 20 years, we have been conducting tests in what is now the largest test laboratory (2,750 m2) for cables and energy chains. Thanks to these tests, we can provide reliable and clear statements that make the durability and service life of our cables predictable for every user. Each chainflex® series has a “double strokes – guaranteed service life table” in the catalogue and additional detailed data in the online chainflex® service life calculator. The prerequisite for the guarantee is that the cables must be operated within the parameters specified in the selection tables for the respective cable series.
