To make the choice easier for you, we have classified all chainflex® types according to the criteria "basic requirements, travel length, oil resistance and torsion". The higher the number, the better the cable.
Example: You are looking for a cable which is suitable for the highest mechanical capability. In an unsupported and gliding application, the travel should be up to 100 m. In addition, the cable is also designed to meet the oil-resistance requirements according to DIN EN 50363-10-2. The cable is not especially designed for torsion applications.
You choose from the classification overview:
Basic requirements: 6 Travel length: 5 Oil resistance: 3 Torsion: 1
This results in the cable's class – here “Class 22.214.171.124”, which you can find on each product's page.

igus® has been supplying cables for permanent movement in e-chains® for more than 25 years now – chainflex® cables, which are quite simply good for one thing:
To achieve this, all chainflex® cables in all e-chain® applications have to cope with demanding requirements, e.g. very small bend radii, high cycle rates, compact installation spaces, a wide range of chemical influences and dynamic parameters.
igus® carries out basic cable qualification tests according to igus® standards at its own technical centre and in the testing laboratory. These chainflex® qualification standards include series of tests which then lead to assignment to the respective igus® "class".
Materials that are to go into series production for chainflex® cables must pass a number of continuous tests in e-chains® in addition to the usual cable-specific standard tests (such as continuous flexing cycle tests, ageing, abrasion, media resistance, or possibly flame retardancy). These test series, which can last up to three years, are always based on movement tests in and with e-chains®/e-chain® materials and include:
These test programs are based in standard specifications from the certification agencies and are performed in accordance with these specifications.
These test series, which can last one to three years depending on the defined goal (e.g. double strokes), are always based on movement tests in and with e-chains® and include:
After a multi-year qualification of the design and the materials, the production processes are qualified and defined down to the machine level, in order to keep the manufacturing tolerance as low as possible.
Cables are of course systematically and continuously sampled from running production and subjected to a lot test. Lot testing at igus® means:
Recording and reviewing the production parameters in relation to the chainflex® cable.
Performance of endurance bending tests in e-chain® testing rigs with short, fast travels.
