free end opposite the mounting should be supported to prevent sagging and possible binding of the
cylinder. The best use of a blind end flange is in a thrust load application (rod in compression).
Rod end flange mounts are best used in tension applications. If an application exceeds the
rectangular flange rating, requiring an extra heavy flange, a solid flange style end cap mount is
available for all bore sizes (refer to page 22). When a less rigid mount can be used and the cylinder
can be attached to a panel or bulkhead, an extended tie-rod mounting could be considered.

 Series H, Double Rod End Dimensional Data

DOUBLE ROD END CYLINDERS

Milwaukee Cylinder's Double Rod End Cylinders are available with all the standard types of Series
Series H

H mountings, except the clevis mount (H61).

To obtain dimensional information on a double rod end cylinder, first select the desired mounting
style and refer to the corresponding single rod end cylinder model shown on the preceding
pages. After you have determined all necessary dimensions from the previous page covering the
desired mounting, turn back to this page. Supplement those dimensions with additional ones
from the drawings below and the table at the right. These added dimensions differ from, or are in
addition to, those shown on the preceding pages and provide the additional information needed
to completely dimension a double rod end cylinder model.
On a double rod end cylinder where two different rod ends are required, or two different rod sizes
are required, or cushions on one end are required, be sure to state clearly which rod is to go at
which end of the cylinder. When two types of mounting styles are required, be sure to specify
their relationship to the piston rods, if they are not the same.
BORE SIZES 1" to 12".

Stop tubes are used to maintain bearing pressure within acceptable limits and are recommended

2$3 The stop tube is a spacer between the rod end cap and the piston, which provides separation
between the piston and the rod bearing. This separation reduces the moment forces developed
 between the rod bearing and piston when the rod is extended.
To determine if stop tube is necessary for your cylinder requirements, you have to solve for “K”
7054;.
2$3 (refer to Figure 1). If your required cylinder has a “K” dimension in excess of 40 inches, stop tube
is required. For each 10 inch increment or fraction thereof in excess of 40 inches, one inch of
 stop tube is recommended. When stop tube is required, the overall length of the cylinder will be
increased by the length of the stop tube to be used.

STORAGE
Often times, cylinders are delivered before a
customer is prepared to install them and must
be stored for a period of time. When storage is
required:
1. Select an area indoors for storage, which
has dry and non-corrosive atmosphere.
Take caution to protect the cylinder from
both internal and external corrosion.
2. Cylinders to be stored should be kept in a
vertical position (piston rod up) whenever
possible.
3. Port protector plugs should be kept in the
cylinder ports until the time of installation.
