RA 17038/02.13
Standards:
Meets or exceeds all JIC and NFPA requirements.
Nominal pressure:
up to 1,500 psi
With extreme shock loads the mounting styles and piston rod
threads have to be considered, taking the fatigue limits into
account.
Maximum operating pressure up to:
1,500 psi
Installation position:
Various
Pressure fluid:
Mineral oils (HL, HLP)
Phosphate ester (HFD-R) (–4°F to 300°F)
HFA (41°F to 131°F)
Water glycol HFC (–4°F to 140°F)
Hydraulic fluid temperature range:
(-4°F to 176°F)
Viscosity range:
32 to 1760 ssu
Degree of contamination:
Max. permissible degree of contamination of the pressure fluid
is to NAS 1638 class 10.
We therefore recommend a filter with a minium retention rate
of
β
10
≥
75.
Stroke speed:
20 in/sec
(dependent on the connection port)
Air bleed standard:
Secured against removal
2" - 8" bore sizes only
Acceptance:
Each cylinder is tested to Bosch Rexroth standards.
Cylinders, outside the above parameters are also available.
Consult factory
For applications above 230°F specify a non studded piston
rod end and advise operating temperature before ordering.
Under no-load conditions, a minimum pressure of 150 PSI is
recommended for single rod cylinders. In case of lower pres-
sures or double rod cylinders, please consult factory.

*1) For double rod cylinders, see page 26.
*2) Exceptions to 1,500 psi rating:
a) MF1 and MF2 have maximum operating pressures
of 1,000 psi for 1-1/2" through 4" bore sizes
b) A 2.5" bore with a 5/8" rod has a maximum pressure
rating of 1,000 psi
3) Consult factory for other pressure ratings than
shown above.
4) For stroke lengths above 60 inches, working pressure
may be derated according to buckling load limits.
Consult factory.

Project planning software ICS (Interactive Catalog System)
The ICS (Interactive Catalog System) is a selection and project
planning tool for hydraulic cylinders. The ICS allows designers
of machines and systems to quickly and reliably find the perfect
hydraulic cylinder solution through logic-guided inquiries. 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 date of the selected component as well as 2D and
3D CAD data in the correct file format for all common CAD
systems. This allows users to reduce costs while increasing
their competitiveness.
The ICS can be accessed at
