2/78 Bosch Rexroth AG | Hydraulics Standards: The installation dimensions and types of mounting of the cylinder comply with the standards DIN 24333 and ISO 6022. Nominal pressure: 250 bar Static test pressure: 375 bar Reduced test pressure: 315 bar The maximum operating pressures must be less than or equal to the applicable nominal pressures and apply to applications with shock-free operation with reference to excess pressure and/or external loads. With extreme loads like e.g. high sequence cycle, mounting elements and threaded piston rod connections must be designed for durability. Minimum pressure:...

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 (MP3/MP5 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 Kinking). • The maximum admissible...
