Pneumatic Information Home : Cylinder Mounting
Mounting Options
We offer several different mounting options for the cylinders we carry.
Mounting Nut
Mounting nuts allow you to mount a cylinder from the top.
Be sure to match the mounting nut thread size to that of the cylinder you will be using.
Package comes with one mounting nut.
Cylinder Mounting Nut
Foot Bracket
Provides a fixed mount for an air cylinder. Does not allow the cylinder to pivot back and forth.
Universal mount cylinders can use the on both the top and bottom, top mount cylinders can
only use them at the top.
Be sure to match the size to that of the cylinder you will be using.
Package comes with one bracket and one mounting nut.
Foot Brackets (2 shown, one on top and one on bottom)
Front Flange
Provides a fixed mount for an air cylinder. Does not allow the cylinder to pivot back and forth.
Universal mount cylinders can use the on the top or bottom, top mount cylinders can
only use them at the top.
Be sure to match the size to that of the cylinder you will be using.
Package comes with one flange and one mounting nut.
Flange
Rear Pivot Mount - One Piece Aluminum
Provides a bottom mount for an air cylinder. Allows the cylinder to pivot back and forth.
Only for use with Universal Mount cylinders.
Be sure to match the size to that of the cylinder you will be using.
Package comes with one pivot bracket, one retaining rod, and one cotter pin.
Rear Pivot Mount
Rear Pivot Mount with Side Mount Bracket option
Rear Pivot Mount - Two Piece Steel
Provides a bottom mount for an air cylinder. Allows the cylinder to pivot back and forth.
Only for use with Universal Mount cylinders.
Be sure to match the size to that of the cylinder you will be using.
Package comes with two pivot brackets (left/right), one retaining rod, and one cotter pin.
Jam Nut
Jam nuts are slightly thinner than normal nuts. Usually two are used together to
sandwich a washer or some other mount on top of a cylinder.
Be sure to match the nut thread size to that of the cylinder piston rod you will be using.
Package comes with one jam nut.
Piston Rod Jam Nuts
Piston Rod Clevis
Use a piston rod clevis to mount to the top of a cylinder shaft.
These allow for some swivel movement.
Be sure to match the size to that of the cylinder you will be using.
Package comes with one clevis, one retaining rod, and one cotter pin.
Piston Rod Clevis
Piston Rod Bumper
Use a rod
bumper to mount to the top of a cylinder shaft. Rod can then be used to push
against a surface. Applications could include pushing up a drop panel, pushing a
crate up and down, opening a lid, etc.
Be sure to match the thread size to that of the cylinder you will be using.
Includes a rubber bumper mounted to a steel threaded shaft and a jam nut.
Piston Rod Bumper
Rod Coupling Nut
Use a Rod Coupling Nut to mount to the top of a cylinder shaft. Screw onto
shaft then screw a bolt into the other end of the Coupling Nut. The bold can
then hold an item.
Be sure to match the size to that of the cylinder you will be using.
 
 
Package comes with one Rod Coupling Nut.
Length of coupling nut depends on the thread size ordered:
1 1/8" long = For our .75" bore cylinders.
1 3/4" long = For our 1.5" bore cylinders.
2 1/8" long = For our 2" & 3" bore cylinders.
Clevis Mounting Bracket
This bracket is for mounting a clevis to. Clevis pin goes through provided hole.
Two 1/4 inch mounting holes provided for you to bolt or screw bracket to coffin
lid, box lid, etc.
Be sure to match the bracket size to that of the cylinder clevis you will be using.
How proper mounting prevents premature cylinder wear
How you mount your
cylinder affects both cylinder performance and cylinder life expectancy. That's
because the wrong mounting or incorrect installation can result in side load.
Side load occurs when a load is placed on the piston rod without guidance or
support, or when the mounting and piston rod connection are misaligned. Side
load creates excessive wear on the piston, piston rod, rod bearing and seals.
Excessive wear leads to leakage and ultimately cylinder failure.
By selecting the right cylinder mounting, you optimize cylinder strength,
efficiency and alignment. Let's look at the two major types of mounts -- pivot
and rigid -- and how they help avoid side load problems.
Pivot type mountings eliminate side loads when properly installed
There are several types of pivot mountings including clevis, pivot and
trunnion. To realize the benefit of a pivot type mounting, it's essential that a
rod eye or rod clevis be used on the piston rod. Otherwise, it becomes a "rigid"
mount cylinder, negating the benefit of the pivot. It's also important that the
axis of all the pivot pins in a set are parallel, or binding and side loading
will occur. Long stroke pivot mount cylinders require stop tubes and dual
pistons to spread out the distance between the rod bearing and piston to reduce
the load at these two points. Trunnion mounted cylinders require that pillow
blocks or mated bearings be fitted as close to the head of the cylinder as
possible to minimize bending stresses in the head.
Get maximum cylinder life with proper rigid mount cylinders
There are a number of rigid mounts available: side-mounted, nose-mounted,
flange-mounted and face-mounted cylinders. Each must be carefully aligned with
the direction of the load travel to avoid side loads. If, for some reason,
proper alignment cannot be achieved, a rod end connection that allows for some
lateral misalignment should be used.
