Every hydraulic cylinder is tested in the factory:
Test pressure = 1.5 x max. operating pressure.
Standards applied:
DIN ISO 6020-2, DIN 24554 (mounting dimensions)
ISO 8133, DIN 24555, DIN 24556 (accessories)
This series is not available in HäKo, but can be requested from Hänchen.
With the respective type of fixation, the operating pressure indicated in the parts list can be exploited statically and dynamically without restrictions. However, the safety respectively required in your system and the stress caused by dynamic movement must be taken into account.
