Application Data
The proper application of a uid power cylinder requires
consideration of the operating pressure, the uid medium,
the mounting style, the length of stroke, the type of piston
rod connection to the load, thrust or tension loading on the
rod, mounting attitude, the speed of stroke, and how the load
in motion will be stopped. Information given here provides
pressure rating data for HV2 Series hydraulic cylinders.
Pressure Ratings
Standard operating uid — clean, ltered hydraulic oil.
Pressure ratings for heavy-duty hydraulic cylinders are shown
in the table.
HV2 Series hydraulic cylinders are recommended for pressures
to 3000 psi for heavy-duty service with hydraulic oil. The 4:1
design factor ratings shown are based on tensile strength
of material and are for standard rod diameter only. The rating
is conservative for continuous severe applications. Design
factors at other pressures can be calculated from this rating.
In addition, mounting styles, stroke, etc., should be considered
because of the limiting eect they may have on these ratings.

Rod End Style 4 Minimum Stroke
Sucient clearance must exist between machining for female
rod end style 4 and the threaded piston-to-rod connection.
This clearance is required to maintain pressure envelope
integrity and envelope ratings shown above.
To maintain the required clearance, a minimum stroke is required
for some bore and rod combinations. See the table below for
minimum stroke requirements. Contact the factory when a style 4
rod end with a stroke shorter than shown in the table is required.
