Product description

Notes
Piston speed based on standard seals: Max. 25 m/min - 0.42 m/sec.
Piston speed to the end positions: max. 6 m/min - 0.10 m/sec.
For these standard cylinders, it is recommended not to weld any fastenings to the cylinder liner (e.g. cardanic mountings) as this could distort it.
Description
Please observe the stipulations of EN ISO 4413 (2011) »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 only be used to a limited extent for applications in construction machinery. In these cases, please consult our technical staff. The cylinders correspond to the technical specifications in the catalogue or are designed according to customer requirements (release designation).
