| 1) | Only with pre-tensioned systems. For non-pre-tensioned systems: amax = 50 m/s2 |
| 2) | Speeds of up to 5 m/s are possible. Service life is limited by increased wear to plastic parts. |
| 3) | Brief peaks up to 100°C are permissible. |
Note on dynamic load capacities and moments (see the table)
Determination of the dynamic load ratings and moments is based on a total travel of 100,000 m.
Often only 50,000 m are actually stipulated. For comparison: Multiply values C, Mt and ML from the table by 1.26.
Observe friction of the different seals. See document “Technical data”.
