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
- bend radius.
Your guarantee will cover up to 4 years 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:
An example: Guaranteed service life for chainflex® CF9
| Double strokes* | 5 million | 7.5 million | 10 million |
|---|---|---|---|
| Temperature from/to [°C] | Minimum bend radius [Faktor x d] | Minimum bend radius [Faktor x d] | Minimum bend radius [Faktor x d] |
| -35°C/-15°C | 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.
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.
