chainflex® guarantee

We issue a guarantee of up to 36 months 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 and 700 experiments concurrently undertaken in our 3,800m² test laboratory.
Why a chainflex guarantee? 
The new guarantee service gives you the assurance that you can design your individual application just right and always choose the chainflex cable that works with reliability.

When does the service life guarantee apply?
The chainflex service life guarantee is valid for the number of double strokes calculated according to the igus online service life calculator, or for up to 36 months from the delivery date, whichever comes first. The guarantee applies to all chainflex cables that can be selected in the service life calculator.

When does a guarantee case exist?
There is a guarantee case when the chainflex cable delivered can be shown to not be free of material errors or manufacturing errors. 
The chainflex cable fails due to natural wear given proper use before the guarantee period has expired or the guaranteed number of double strokes has been reached.

When is there no guarantee case?
The guarantee expires if there is mechanical damage due to faulty installation or improper cable use.

When does the guarantee start?
The guarantee is valid for new purchases as of 15/02/2020. It starts on the date the chainflex cable is delivered.

When does the guarantee end?
The guarantee ends after 36 months, starting from the delivery date.
What is included in the scope of guarantee?
Guarantee claims must be submitted to igus GmbH immediately after the damage described above is detected. For the given guarantee period, igus provides a free replacement (delivery ex works). This applies only to igus chainflex components that fail due to wear and tear.

Is the guarantee prolonged due to the delivery of a replacement?
Shipping of replacement parts does not prolong the guarantee period.

Is there a guarantee for the e-chain used?
We also offer a guarantee of up to 36 months on the e-chain used. More information

In which countries is the chainflex guarantee valid?
The chainflex guarantee is valid worldwide. The issuing authority is igus GmbH, no matter where you request the guarantee certificate from via the service life calculator.

Predictable safety through laboratory & field experience

Safety is of the utmost essence, not only operationally, but also legally and financially. Plant and machine constructors always have to make binding statements about operational safety and reliability. Therefore, a guarantee declaration to the end customer always entails a risk.
We are aware of this, but due to our many years of experience and our expertise we can guarantee manufacturers valuable planning security. Intensive tests in the world's largest test laboratory for cables and energy chains allow us to make valid, reliable and verifiable statements about durability and service life.
Providing a guarantee to the end customer exceeds obligatory warranty claims or defect liability by far. The customer not only receives the promise from the company to obtain a defect-free product, but also the ability to function over a certain period.
Durability guarantee is what matters. This is very important for customers, as a binding statement regarding the durability, offers planning security. A mere extension of the guarantee is usually not enough for them.
The chainflex guarantee provides you with reliable data from the lab and the field!
The chainflex guarantee assumes the operating conditions are applicable for the respective cable group. These conditions consist of parameters such as temperature, movement type, torsion, media influence, and bend radius. Your guarantee will cover up to 36 months or ten million double strokes (for cables of the chainflex 800 family, up to five million double strokes, and for high-end-type cables, up to 40 million double strokes), whichever comes first. The number of double strokes covered by the guarantee depends on the type of installation and the cable quality. These factors are described in the current catalogue, the data sheets, and the service life calculator.

It's simple:

Service life calculator Call up service life calculator and enter application parameters
Service life calculator Click on calculate to work out the chainflex cable's service life

Example: "guaranteed service life" for chainflex CF9

* Higher number of double strokes? Calculate service life online
 Double strokes*5 million7,5 million10 million
 Temperature from/to [°C]Minimum bend radius [factor x d] Minimum bend radius [factor x d] Minimum bend radius [factor x d]  
 -35/-156,8 7,5 8,5 
+90/+100 6,8 7,5 8,5 

In this chart, you can find the technical parameters of the chainflex CF9 control cable. If the cable is operated in accordance with the operating conditions, a guaranteed service life of 5, 7.5 or 10 million double strokes is applicable depending on the application. The service life itself can even be significantly higher.
Suppose you use a cable with a diameter of 12mm in an energy chain with a radius of 100mm. This results in a bending factor of 8.3 (100mm/12mm). To receive a statement regarding the durability, you require the information from the technical framework conditions (temperature and number of double strokes). With an assumed temperature range of -25/+90°C) with 8xd, the effective bending factor is above the minimum limit of 7. 10 million double strokes are guaranteed! With higher or lower temperature, the necessary factor for this guarantee level would be 8.5. This means that the number of guaranteed double strokes is reduced to 7.5 million.
These statements provide reliability and planning safety for your entire plant!

chainflex UL label

Why should the product keep the promises?

UL verified: chainflex® receives the highest recognition by globally recognised testing organisation

igus is the first German company to have this promise validated for chainflex cables. In a complex certification process, the US "Underwriters Laboratories" institute confirmed the accuracy of the "igus 36-month chainflex cable guarantee and service life calculator based on 2 billion test cycles per year" promise. 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 anywhere in the world will be identified by the UL marketing label with its unique number (B129699) that refers to igus.
A total of 1044 of the over 1350 cables in the portfolio and available from stock already have classic UL approval. This is a prerequisite for the smooth commissioning of systems in the USA. The export of systems to America will therefore run smoothly. The combination of UL approval and a UL marketing label benefits 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! Learn more about UL verified:
