Sheffer HH SERIES - Manual (Page 18)

IMPORTANT NOTICE
There is a construction variance in
the 1
1 / 8 " bore, 1 1 / 2 " bore, 2" bore,
the 2 1 / 2 " bore with a 1 3 / 8 " and 1 3 / 4 "
rod diameter, and the 3 1 / 4 " bore
with a 2" rod diameter. The round
gland retainers shown above are not
used in these sizes. A square
retainer, the same square size as the
head, is employed on each end. The
retainers are held in place by the tie
rod nuts and therefore cannot be
removed without loosening the tie
rods.
See adjacent drawing for dimension
details.
For dimensions on specific
mounting styles, consult other
pages in this brochure and separate
Accessories Brochure. Dimensions
shown on the above and adjacent
drawings are for the BASIC
CYLINDER ONLY.
Double rod extension cylinders are
available in every mounting style
except clevis.
IMPORTANT NOTICE
Reference adjacent drawing.
