Description

Please observe the stipulations of EN ISO 4413 “Safety requirements for fluid power systems and their components” as well as specifications and safety requirements based on statutory regulations when selecting, installing and operating the cylinders.
Our hydraulic cylinders and their components are designed for standard applications in industry and agriculture. They can be used only in some circumstances for applications in construction machinery. If this is your intention, please contact our technical personnel. The cylinders conform to the technical specifications in the catalogue or are designed to customers' specifications (approval drawing).

Hints

Piston speed based on standard seals: Max. 25m/min - 0.42m/sec.
Piston speed to the end positions: max. 6m/min - 0.10m/sec.
For these standard cylinders, it is recommended not to weld any fastenings to the cylinder liner (e.g. cardan mountings) as this could distort it.
