chainflex® guarantee

What is the chainflex® guarantee?

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.

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.

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.
In your application, 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.

chainflex UL label

How does the product keep this promise?

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 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 ensure 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:
