Double stroke selection tables – guaranteed service life

All chainflex® series have a 'double strokes selection table - guaranteed service life'. This describes the technical parameters of the chainflex® cables. The guarantee is subject to the use of the cables in line with the usage conditions specified in the selection tables for the relevant cable series.

Selection table "Guaranteed service life" for CF9

*Higher number of double strokes possible.

Example CF9:

You operate a cable with a diameter of 12 mm in an energy chain with a radius of 100 mm. This results in a bending factor of 8.3 (100 mm/12 mm). You now want to know the guaranteed durability.
To find this out, select the technical framework conditions from areas 1 to 4. In area 5, you can now see that when using 8.3 x d the effective bending factor is above the limit of 7 and the cable has a guaranteed service life of 10 million double strokes.
If the temperature is higher or lower, the number of guaranteed double strokes falls to 7.5 million.
