All chainflex® cables have a UL-verified 36 month guarantee for service life

igus® 36-month chainflex® cable guarantee and service life calculator based on 2 billion test cycles per year

igus® has been testing the service life of chainflex® cables for over 20 years in their 41,000 sq. ft. test laboratory located at their headquarters in Cologne, Germany.  In particular, the testing process is unique because of the extremely rigorous, holistic and systematic processes and batch testing that is applied to all cables in the test lab. 

Because of these rigorous tests, igus® can provide customers with the predicted durability of every chainflex® cable, with a UL-verified 36 month guarantee.  Learn more about the UL Test Process Verification.

The results of these tests are recorded in the database of the chainflex® service life calculator, where users can enter the speciifcations of their application, configure their expected service life and easily place an order.  Use the calculator here.  To browse all of our cables in the chainflex® online shop, click the button below.

chainflex UL logo

We issue a 36-month guarantee on our cables with confidence, as we are able to make reliable predictions about the service life of our cables due to over 30 years of experience in our 4,100ft² test laboratory and 700 concurrently undertaken experiments.
The company igus is now the first German firm to have this promise validated for chainflex cables. In a complex certification process, the US institute "Underwriters Laboratories" confirmed the accuracy of the statement "igus® 36-month chainflex cable guarantee and service life calculator based on 2 billion test cycles per year". This makes the Cologne-based company the first in Europe to have the veracity of an advertising statement confirmed by a testing institution. In future, every chainflex® cable that leaves the factory worldwide will be identified by the UL marketing label with its unique number, referring to igus®.

A total of 1044 of the over 1350 cables in the portfolio and available from stock already have classic UL approval, without which the export of systems to America would in all probability run less smoothly. The combination of UL approval and UL marketing label ensures smooth exports twice over.
These statements create reliability and planning security for your entire investment process; all the more so now that they have been confirmed by an external body! You are welcome to try it out yourself online with the certified service life calculation.
