To determine the service life of its products, igus puts them through their paces under the most adverse conditions, up to failure, in its 41,000 square foot test laboratory. Up to 10 billion test cycles are completed each year in the test lab. Using the data gained, the e-chain service life calculator determines the operating time of the igus standard energy chains in specific applications. Over 4,000 tests and more than 7,500 results flow into the online tool. More tests are performed every day in the endeavour to deliver more precise statements about the service life. Therefore, igus is the only supplier in the world to offer a 36 month guarantee on their energy chains.
