Design Data
With the Sheffer S.A.F.E. (Self-Aligning
Flange End) Coupling, close radial
alignment between cylinder rod end and
machine member is easily and quickly
achieved. Thus, cylinder installation is
faster, cylinder life longer.
Consider how a threaded rod end is
usually joined to a machine member.
First, the hole for the rod end must be
located, then drilled or bored, and
tapped or chased. These are critical
operations and to avoid misalignment,
they must be done with extreme care.
(Boring and chasing equipment are not
always available.)
With the Sheffer S.A.F.E. Coupling,
however, mounting goes fast. Using the
bolt circle information on this page, the
mounting holes are scribed, drilled and
tapped. Close radial alignment is
achieved every time!
Because correct alignment means less
wear of component parts, Sheffer
S.A.F.E. Coupling allows for radial
misalignment without causing abnormal
rod bearing wear, short seal life, or
possible damage to the I.D. of the
cylinder tube. It is not designed, how-
ever, to compensate for angular mis-
alignment. For this problem, ask your
distributor about the Sheffer R.A.C. (Rod
Aligning Coupler) mounting accessory.
(See also Page AC-15.)
The S.A.F.E. Coupling also assures a
stronger connection between rod end
and machine member than a threaded
rod end. The flat rod end takes the full
load on the push stroke, and the
machined shoulder of the rod and the
S.A.F.E. Coupling take the maximum
loading force that the cylinder is capable
of producing on the pull stroke.
The flange is made from solid steel.
High tensile, socket head cap screws,
designed to take full loading with a safety
factor, are provided. S.A.F.E. Coupling
is for use with Sheffer Style 6 rod ends.
Also available as a convenient
accessory (optional at extra cost) is a
Weld Plate to match each S.A.F.E.
Coupling. Shown on the adjacent
drawing, the Weld Plate provides the
perfect answer to the customer who
would prefer to weld a pre-drilled and
tapped, properly sized plate to the
machine member, rather than laying out,
drilling and tapping each hole in the
member itself. The Weld Plate is
equipped with an accurately drilled
locator pin hole to facilitate fast, close
tolerance positioning. Low carbon steel
is used for ease in welding.
• Faster close radial alignment
important for long cylinder life
• Less critical rod end to machine
attachment
• Use with any Sheffer cylinder with
1
/
2
” or larger rod diameter
• Use with no-extra-cost Sheffer
style 6 rod end
• Faster cylinder installation and
removal
• Better force distribution on push
and pull strokes
• High tensile, socket head cap
screws provided
• Available for immediate delivery
• For use with fixed mount cylinders
