Chainflex® Guarantee Program

We confidently offer this guarantee because we...

...conduct over 2.0 billion test strokes and 1.4 million electrical measurements per year:

Our customers often have to offer end customers guarantees on their systems in order to show that these are safe and reliable.The end customer's desire for a guarantee is entirely understandable but means a commercial risk for the system manufacturer. With our guarantee we now offer planning reliability to our customers, the system manufactures. The guarantee is not the same as a standard guarantee. In Germany, both quality and durability guarantees are used.

Chainflex® Guarantee Program  
Plannable reliability

Customers have always asked for statements about durability. For over 20 years, we have been conducting tests in what is now the largest test laboratory for cables and Energy Chains®. Thanks to our series of tests, we are now able to offer clear and reliable statements that enable our cable users to plan more effectively with regard to durability and service lives.

Double stroke selection tables - guaranteed service life

All chainflex® series have a 'double strokes selection table - guaranteed service life'. This describes the technical parameters of the chainflex® cables. The guarantee is subject to the use of the cables in line with the usage conditions specified in the selection tables for the relevant cable series.

*Higher number of double strokes possible.


You operate a cable with a diameter of 12 mm in an energy chain with a radius of 100 mm. This results in a bending factor of 8.3 (100 mm/12mm). You now want to know the guaranteed durability.
To find this out, select the technical framework conditions from areas 1 to 4. In area 5, you can now see that when using 8.3 x d the effective bending factor is above the limit of 7 and the cable has a guaranteed service life of 10 million double strokes. If the temperature is higher or lower, the number of guaranteed double strokes falls to 7.5 million.
