2/70 Bosch Rexroth AG | Hydraulics • Installation dimensions according to ISO 6020-2 and NF/ISO 6020-2 • 13 types of mounting • Piston 0 (0AL): 25 to 200 mm • Piston rod 0 (0MM): 12 to 140 mm • Stroke lengths up to 3000 mm • Integrated guide socket for fast and easy maintenance • Self-adjusting or adjustable end position cushioning as option • Patented safety vent for easy and safe bleeding • Easy assembly thanks to freely selectable position of the line connections at head and base Maximum operating pressure (only static load): 210 bar (21 MPa) Static test pressure: 240 bar (24 MPa) For...

Hydraulics | Bosch Rexroth AG Technical data (For applications outside these parameters, please consult us!) Boundary and application conditions: • The mechanical alignment of the movement axis and thus the mounting points of hydraulic cylinder and piston rod must be ensured. Lateral forces on the guides of piston rod and piston are to be avoided. It may be necessary to consider the own weight of the hydraulic cylinder (MP1, MP3, MP5, MT1, MT2 or MT4) or the piston rod. • The bending length/bending load of the piston rod and/or the hydraulic cylinder must be observed (see page topic...

If necessary, please consult us. If the extension velocity is considerably higher than the

Hydraulics | Bosch Rexroth AG Information on stroke length and stroke velocity 0AL (mm) The ICS (Interactive Catalog System) is a selection and project planning aid for hydraulic cylinders. The ICS allows designers for machines and systems to quickly and reliably find the perfect hydraulic cylinder solution through logic-guided type key enquiries. This software helps to solve design and project planning tasks more quickly and efficiently. After having been guided through the product selection, the user quickly and reliably gets the exact technical data of the selected component as well as...
