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 (for Retainer Held Bushings) – 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 W.
If otherwise special,
furnish dimensioned
sketch.
See B&R Table to determine which bore, rod and mount combinations have this feature.
A high strength rod end stud is supplied on thread style 2 through
2.000" diameter rods. Larger 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 2 rod ends are recommended through 2.000" piston rod
diameters and style 5 rod ends are recommended on larger
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.
