Bleeding

By default secured against screwing out1)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.2)Depending on the application, application conditions and technical design, a certain minimum pressure (approx.10 bar) is required in order to guarantee technically unobjectionable functioning of the hydraulic cylinder.3)The cleanliness classes specified for the components must be adhered to in hydraulic systems. Effective filtration prevents faults and simultaneously increases the life cycle of the components. For the selection of the filters, see www.boschrexroth.com/filter.

Generally, a medium temperature of approx. 40 °C is recommended. The specified values are to be regarded as guidelines; depending on the case of application, it may be necessary to check the suitability of the seal system.1)Moreover, observe the corresponding medium temperature range2)Lower temperature limit –15 °C3)Standard line connections not designed for that velocity4)‒ = Seal is destroyed,  + = Seal is not directly destroyed, leakage may occur

Higher stroke velocities upon request. If the extension velocity is considerably higher than the retraction velocity of the piston rod, drag-out losses of the medium may result. If necessary, please consult us.

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 bending).

The maximum admissible stroke velocities with regard to the suitability/load of seals must be observed as must their compatibility with the properties of the hydraulic fluid (see seals).

The maximum admissible velocities/kinetic energies when moving into the end positions, also considering external loads, must be observed.Danger: Excess pressure

The maximum admissible operating pressure must be complied with in any operating state of the hydraulic cylinder. Possible pressure intensification resulting from the area ratio of annulus area to piston area and possible throttling points are to be observed.

Detrimental environmental influences, like e.g. aggressive finest particles, vapors, high temperatures, etc. as well as contaminations and deterioration of the hydraulic fluid are to be avoided.
