Model 72 cylinders have mounting lugs welded to the head
and cap, and are considered to be a xed mount that does not
absorb force on its centerline. The plane of the mounting surface
is not through the centerline of the cylinder, and for this reason
Model 72 cylinders produce a turning moment as the cylinder
applies force to the load. This turning moment tends to rotate
the cylinder about its mounting bolts. If the cylinder is not well
secured to the machine member on which it is mounted or the
load is not well-guided, this turning moment results in side load
applied to rod bushing and piston bearings. To avoid this
problem, Model 72 cylinders should be specied with a
stroke length at least equal to the bore size.
Model 74 cylinders have side tapped holes for ush mounting,
and are considered to be a xed mount that does not absorb
force on its centerline. The plane of the mounting surface is not
through the centerline of the cylinder, and for this reason Model
74 cylinders produce a turning moment as the cylinder applies
force to the load. This turning moment tends to rotate the
cylinder about its mounting bolts. If the cylinder is not well
secured to the machine member on which it is mounted or the
load is not well-guided, this turning moment results in side load
applied to rod bushing and piston bearings. To avoid this
problem, Model 74 cylinders should be specied with a
stroke length at least equal to the bore size.
Rod End Dimensions — see Table 2
“Special” Thread
Style X
Special thread,
extension, rod eye,
blank, etc., are also
available.
To order, specify
“Style X” and give
desired dimensions
for KK, A and WF.
If otherwise special,
furnish dimensioned
sketch.
Over 2.000" rod sizes or special rod ends are cut threads. Style 2 rod
ends are recommended where the workpiece is secured against the
rod shoulder. When the workpiece is not shouldered, style 5 rod ends
are recommended over 2.000" piston rod diameters. Use style 4 for
applications where female rod end threads are required. If rod end
is not specied, style 2 will be supplied. On 5.000" rods and above,
(4) .515 dia. spanner wrench holes will be provided instead of
wrench ats.
