36 month guarantee - for every chainflex cable

Durable and fail-safe cables

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 and 700 concurrently undertaken experiments in our 3,800 m² test laboratory.
There are five main focus areas: 1. Tests of materials
2. Tests of the technical design
3. Quality tests during production
4. Long-term tests and tests of service life
5. Customer-specific applications

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 valid for the respective cable family. These consist of parameters such as temperature, movement type, torsion, media influence and bending radius. You will receive the guarantee for 36 months or 10 million double strokes (with cables of the chainflex 800 family up to 5 million, with high-end cables up to 40 million double strokes); depending on which occurs first. The number of double strokes depends on the type of installation and the cable quality.
These are described in the current catalogue, in the data sheets and in the service life calculator.

Example: "guaranteed service life" for chainflex CF9

* Higher number of double strokes?Calculate service life online
Double strokes*	5 million	7,5 million	10 million
Temperature from/to [°C]	Minimum bend radius [factor x d]	Minimum bend radius [factor x d]	Minimum bend radius [factor x d]
-35/-15	6,8	7,5	8,5
-25/+90	5	6	7
+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!
