If only one end of these Double Rod Cylinders is to
be cushioned, be sure to specify clearly which end
this will be.

Specify XI dimension from rod end #1.
To obtain dimensioning information on a
double rod cylinder, rst select the desired
mounting style and refer to the corresponding
single rod cylinder model shown on the
preceding pages. (See table at left.) After you
have determined all necessary dimensions
from that drawing, turn back to this page and
supplement those dimensions with additional
ones from the drawing above and table at
right. These added dimensions dier from,
or are in addition to, those shown on the
preceding pages and provide the additional
information needed to completely dimension
a double rod cylinder model.
On a double rod cylinder where the two rod
ends are dierent, be sure to clearly state
which rod end is to be assembled at which
end. Port position 1 is standard. If other than
standard, specify pos. 2, 3 or 4 when viewed
from rod end #1 only. See port position
information on ports page.
Mounting Recommendations and Other Mountings
In addition to the standard mountings dimensioned on the preceding
pages, the following information covers mounting ideas that may
prove helpful in your applications. When needed, special heads, caps,
and anges can be provided. Sketches of your requirements, together
with specications relative to the application and forces involved
should be submitted.
Mounting Bolts — High tensile socket head screws are recom-
mended for all mounting styles.
Flange Mountings — Cylinders can be properly centered by
measuring from piston rod diameter. After mounting, the ange may
be drilled for pins or dowels to prevent shifting.
Side Lug Mountings — Caution, cylinders which do not absorb
force on their centerline (Group 3) tend to sway when under load.
Short stroke, non-centerline mounted cylinders can subject mounting
bolts to large tension forces which when combined with shear forces
can overstress standard mounting bolts. Side lug mounted cylinders
should always be prevented from shifting through use of shear keys
so located as to resist the major load, whether push or pull.
Trunnion Mountings — Cylinders require lubricated pillow blocks
with minimum bearing clearances. Pillow blocks should be carefully
aligned and rigidly mounted so the trunnions will not be subjected to
bending moments. The rod end connection should also be pivoted,
with the customer’s pin in the piston rod eye parallel to the trunnions.
Clevis Mountings — Cylinders should be pivoted at both ends,
with the customer’s pin in the piston rod eye parallel to the pivot pin
supplied with the clevis.
Metallic Rod Wiper
When specied, metallic rod wipers can be supplied at extra cost,
instead of the standard synthetic rubber wiperseal. Recommended in
applications where atmospheric particles or splashings tend to cling to
the extended piston rod and otherwise damage the synthetic rubber
wiperseal. Installation of metallic rod wiper does not aect cylinder
dimensions.
