Operating Pressures (PSI) by Cylinder
Bore Sizes*
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)

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
≥ 75.

Stroke speed: 20 in/sec
(dependent on the connection port)
*1) For double rod cylinders, see page 26.
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 pressures or double rod cylinders, please consult factory.
*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 www.boschrexroth.com/ics.

Stroke Tolerances
Stroke tolerances result from the cylinder head, cylinder base, cylinder tube, piston and piston rod. The stroke tolerance for all piston
diameters and stroke lengths is +1/16" / -0". Tighter stroke tolerances can be requested, however, details regarding the operating
pressure and operating temperature must be stated.

Flange mounts are one of the strongest, most rigid methods of mounting.
With this type of mount, there is little
allowance for misalignment, so when
long strokes are required, the free end
opposite the mounting should be supported to prevent sagging and possible
binding of the cylinder. Blind or cap
end mounts are best for thrust load applications, and rod or head end mounts
are best in tension applications. If an
application exceeds the rectangular
flange rating, a solid head or cap flange
mount is available.
When a less rigid mount can be used
and the cylinder can be attached to a
panel or bulkhead, an extended tie rod
mount could be considered.
Note: The bearing retainer plate is the
same as the “E” dimension for the 1.5”
– 6” bore sizes. Removable bearing
retainer is not available in the 1.5” – 6”
bore sizes.

The Clevis or Pin mounted cylinder is probably
the most widely used
of all mounts. For short
strokes, medium or
small cylinder applications, the clevis mounts
are recommended. If
this mount is applied
where stroke requirements cause the overall
length to be excessive,
the Cap Trunnion mount
can be used. Pivot
mounts must always be
used with a pivot type
rod end attachment.
The bearing retainer
plate is the same as the
“E” dimension for 11/2”–6” bore sizes and
the “XN” dimension for
the 8” bore sizes. Rod
end options shown on
page 6.
MP1 mount includes
pivot pin. MP3 does not
include pivot pin.

The MP5 (Universal) type mount is a pivot mount
with a spherical bearing fitted into the pivot
to permit 5 to 10 degrees of movement in a
plane perpendicular to the major plane of pivot
movement. It is probably the most serviceable
of the pivoted centerline mounts. For maximum
effectiveness, a spherical rod end fitting should
be utilized at the same time.
Rod end options shown on page 6.
Note: Only one (1) grease nipple is supplied up to 2.50” bore. On bore sizes 2.50” and larger, two (2) grease nipples will be
supplied, as shown.

The side or lug mounted cylinder provides a fairly rigid mount.
These type mounts can tolerate a slight amount of misalignment when the cylinder is at full stroke, but as the piston
moves toward the blind end, the tolerance for misalignment
decreases. It is important to note that if the cylinder is used
properly, the mounting bolts are either in simple shear or tension without any compound stresses. An extended key plate
option is available to eliminate the need for fitted bolts or
external keys to carry the thrust load.
Note:
When specifying an MS2 mount with ports in the 2 or 4 quandrant, be sure to see that sufficient clearance between the port
fitting and the lug is available to insert a bolt or cap screw into
the lug.
