IMPORTANT
Trunnion Mount Cylinder
When ordering a Trunnion Mount
cylinder, the XI dimension must be
given to fix the position of the
trunnion. The XI minimum is the
shortest dimension that can be
considered since it positions the
trunnion right up against the head.
When a cylinder is cushioned front,
the trunnion would cover the
cushion insert, allowing no access
to the adjusting screw if the XI
minimum dimension were specified.
It is therefore recommended that, in
such a case, the trunnion position
be specified no closer to the head
than the XI minimum plus the
cushion insert thickness. The
cushion insert thickness is given
in the adjacent chart.
The XI maximum is a dimension
that, when added to the stroke,
would place the trunnion tight up
against the cap of the cylinder. If a
cylinder is cushioned front, the
cushion insert thickness should be
added to determine that maximum
dimension. If the cylinder is
cushioned rear or cushioned both
ends, it is not recommended that
the thickness of the rear cushion
insert be added to determine the
maximum XI dimension, since that
would position the trunnion over
the cushion rear insert, and access
to the cushion adjusting screw
would not be possible.
Double Rod End Cylinders
When the rod ends of a double rod
end cylinder are not to be the same,
such as a style 3 on one end and a
style 4 on the other, be sure to
specify and to identify which end is
which in relation to the flange if
cylinder is a Front Flange Mount.
