By default secured against screwing out1)The maximum operatingpressures must be less than or equal to the applicable nominalpressures and apply to applications with shock-free operation withreference to excess pressure and/or external loads. With extremeloads like e. g. high sequence cycle, mounting elements andthreaded piston rod connections must be designed fordurability.2)Depending on the application, application conditionsand technical design, a certain minimum pressure(approx.10 bar) is required in order to guarantee technicallyunobjectionable functioning of the hydraulic cylinder.3)Thecleanliness classes specified for the components must be adhered toin hydraulic systems. Effective filtration prevents faults andsimultaneously increases the life cycle of the components. For theselection of the filters, see www.boschrexroth.com/filter.

If the extension velocity isconsiderably higher than the retraction velocity of the piston rod,drag-out losses of the medium may result. If necessary, pleaseconsult us.
The mechanical alignment of the movement axis and thus the mountingpoints of hydraulic cylinder and piston rod must be ensured.Lateral forces on the guides of piston rod and piston are to beavoided. It may be necessary to consider the own weight of thehydraulic cylinder (MP3/MP5 or MT4) or the piston rod.

?

The bending length/bending load of the piston rod and/or thehydraulic cylinder must be observed (see bending).

The maximum admissible stroke velocities with regard to thesuitability/load of seals must be observed as must theircompatibility with the properties of the hydraulic fluid (seeseals).

The maximum admissible velocities/kinetic energies when movinginto the end positions, also considering external loads, must beobserved.
Danger: Excess pressure

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

Detrimental environmental influences, like e.g. aggressivefinest particles, vapors, high temperatures, etc. as well ascontaminations and deterioration of the hydraulic fluid are to beavoided.
