Series A & EA, NFPA Aluminum Air Cylinders, Impact Dampening Seals

Energy Absorption
Capacity of the Impact
Dampening Seals

The impact-dampening
Piston Seals in the Series EA cylinder
allow for guaranteed, repeatable cushioning.
The compressive qualities of the piston seals are
predictable. The degree of seal compression at
various supply pressures is documented. (See
Energy Absorption Chart.) This allows you to
compute the exact cylinder size required by
knowing the weight (pounds) you are stopping
at a given speed.

Series EA cylinders have a impact dampening
piston seal that accomplishes 80% of the actual
load stopping. The air cushion accounts for only
20%. (A conventional air cushioning cylinder
depends 100% on the compressibility of air to do
the stopping.) The EA seal absorbs high impact
loads allowing the effect of the air cushion to be
reduced by using a larger air cushion bleed
orifice. As a result the piston can move at a faster
speed for a longer period of time before the EA
seal does the final stopping.
See illustration at top of ACT-1-5 for cushion
operation.

Norgren Ecology Cylinders offer these advantages:

Norgren Guarantees
Non-lubricated Operation
for a Full Year!

The piston rod is self-lubricated by the
oil-impregnated rod bearing during operation.
Lubrication between piston and cylinder barrel
is derived from the polishing qualities of the
reinforced Teflon

®

wear ring.

The low friction surfaces extend the life of the
seals beyond normal expectations, permitting
Norgren to unconditionally guarantee non­lubricated
operation for one full year. See page ACT-1-98 for
complete warranty.

Series EA cylinders are NFPA interchangeable
and are available in many different mounting styles.

Operates Quietly
to Meet
OSHA Specifications.

Series EA cylinders provide substantial reductions
in impact noise, which reduces overall machine
noise and helps meet government regulations.

The summary of sound decibels chart illustrates the
operating sound levels.

The impact dampening qualities of the
Piston Seals are guaranteed for ONE FULL YEAR!

Summary of Sound Levels in Decibels

+Peak sound pressure is given in decibels (dB)

re:2 x 105N/m2.

++End position of mike was 3' on centerline from end of

cylinder; side position of mike was 3' perpendicular to
centerline abeam of end of cylinder.

Note: At 5 feet, cylinder sound levels would be less by 9 dB
from side figure and 13 dB from end figure. The total noise
emitted will depend on the structure to which the cylinder is
attached. If it is mounted on a thin flat plate of considerable
area, the noise will be increased by a sounding board effect.

Effect of Impact Dampening Seals on Total Stroke of Cylinders

*The weight of the cylinder piston has been deducted from the figures shown above.
Note: The use of Viton

®

Seals limits the absorption of the impact dampening seals by 50%.

Energy Absorption Capacity of the Impact Dampening Seals

*Usable Pounds Stoppable at the Following Piston Speeds

This chart features the energy absorption capacity of the impact dampening piston seals
with Non-Adjustable cushions. For higher loads and velocities please refer to the Decel-Air™ Cushion
Option on ACT-1-10.

Note: These figures are for new cylinders. The impact dampening seals will take some compression set during operation
of the cylinder and the stroke loss will decrease. Also, the pressure at zero stroke loss will decrease to about 80 psi.
At pressures above those of zero stroke loss, a slight clicking sound may be produced during impact.

To determine the stroke loss for either the head or cap end, divide the value shown by 2.

Air Cylinder Selection:

The proper application and selection of an air
cylinder requires full consideration of the
following: the fluid medium, operating
pressures, mounting style, length of stroke,
type of rod connection to the load, thrust or
mounting tension on the rod, mounting
attitude, speed of the stroke and how the load
motion will be stopped.

The data that follows provides the necessary
information in the evaluation of

an average application and will help you in
selecting the proper cylinder model and size
for your particular application.

Note: 1-1/2", 2", 2-1/2", 3-1/4", 4" and 5" bore
cylinders with 1/2" to 2" strokes will be

A Major Design and Performance Breakthrough in Air Cylinder Cushioning Systems!

Norgren’s advanced cushion design features a unique, one­piece, nitrile compound seal that is captured within a
precision machined groove. This allows both linear
and radial “float” of the cushion seal which
virtually eliminates problems associated
with misalignment. Integral flow paths
molded in the periphery of the seal provide
exceptionally fast “out of cushion” stroke
reversal without the use of ball checks.

Ultra Cushion

®

Figure 1 Figure 2 shows spear

exiting cushion seal.

On the reverse stroke the EJ seal releases its compressive
energy to propel the piston away from the end caps,
producing an immediate breakaway.

As the piston continues its travel to the point of impact
with the end caps, the compressive qualities of the EJ seal
provide the final decelerating force. This action compresses
the EJ seal and absorbs the remaining kinetic shock
vibration and noise created by the impact.

As the cushion spear enters the cushion cavity, the
exhaust port becomes sealed off creating an air brake.This
provides the initial deceleration in piston speed. The
oversized air cushion bleed orifice permits the cushion
pressure to exhaust with minimal restriction. This allows
the piston to move quickly and smoothly through the
cushion length.

Energy Absorption
Capacity of the Impact
Dampening Seals

The impact-dampening
Piston Seals in the Series EJ cylinder
allow for guaranteed, repeatable cushioning.
The compressive qualities of the piston seals are
predictable. The degree of seal compression at
various supply pressures is documented. (See
Energy Absorption Chart.) This allows you to
compute the exact cylinder size required by
knowing the weight (pounds) you are stopping
at a given speed.

Series EJ cylinders have a impact dampening
piston seal that accomplishes 80% of the actual
load stopping. The air cushion accounts for only
20%. (A conventional air cushioning cylinder
depends 100% on the compressibility
of air to do the stopping.) The EJ seal absorbs
high impact loads allowing the effect of the air
cushion
to be reduced by using a larger air cushion bleed
orifice. As a result the piston can move at a faster
speed for a longer period of time before the EJ
seal does the final stopping. See illustration at top
of ACT-1-9 for cushion operation.

Summary of Sound Levels in Decibels

+Peak sound pressure is given in decibels (dB)

re:2 x 105N/m2.

++End position of mike was 3' on centerline from end of

cylinder; side position of mike was 3' perpendicular to
centerline abeam of end of cylinder.

Note: At 5 feet, cylinder sound levels would be less by 9 dB
from side figure and 13 dB from end figure. The total noise
emitted will depend on the structure to which the cylinder is
attached. If it is mounted on a thin flat plate of considerable
area, the noise will be increased by a sounding board effect.

Effect of Impact Dampening Seals on Total Stroke of Cylinders

*The weight of the cylinder piston has been deducted from the figures shown above.
Note: The use of Viton®Seals limits the absorption of the impact dampening seals by 50%.

*Usable Pounds Stoppable at the Following Piston Speeds

This chart features the energy absorption capacity of the impact dampening piston seals
with a Non-Adjustable cushions. For higher loads and velocities please refer to the Decel- Air
Cushion option on ACT-1-10.

Note: These figures are for new cylinders. The impact dampening seals will take some compression set during operation
of the cylinder and the stroke loss will decrease. Also, the pressure at zero stroke loss will decrease to about 80 psi.
At pressures above those of zero stroke loss, a slight clicking sound may be produced during impact.

To determine the stroke loss for either the head or cap end, divide the value shown by 2.

Air Cylinder Selection:

The proper application and selection of an air
cylinder requires full consideration of the
following: the fluid medium, operating
pressures, mounting style, length of stroke,
type of rod connection to the load, thrust or
mounting tension on the rod, mounting
attitude, speed of the stroke and how the load
motion will be stopped.

The data that follows provides the necessary
information in the evaluation of

an average application and will help you in
selecting the proper cylinder model and size
for your particular application.

Note: 1-1/2", 2", 2-1/2", 3-1/4", 4" and 5" bore
cylinders with 1/2" to 2" strokes will be
furnished with a short head cushion sleeve
and short cap cushion spear.
Only available on 5/8" and 1" rods.

The above specification applies to Series J
cylinders with optional non-adjustable or
adjustable cushions.

Series J Fixed Cushions

Piston and rod
assembly for
1-1/2" thru 5"
bore cylinders
with 1/2" to 2" stroke.

On the reverse stroke the EJ seal releases its compressive
energy to propel the piston away from the end caps,
producing an immediate breakaway.

As the piston continues its travel to the point of impact
with the end caps, the compressive qualities of the EJ seal
provide the final decelerating force. This action compresses
the EJ seal and absorbs the remaining kinetic shock
vibration and noise created by the impact.

As the cushion spear enters the cushion cavity, the
exhaust port becomes sealed off creating an air brake.This
provides the initial deceleration in piston speed. The
oversized air cushion bleed orifice permits the cushion
pressure to exhaust with minimal restriction. This allows
the piston to move quickly and smoothly through the
cushion length.

A Major Design and Performance Breakthrough in Air Cylinder Cushioning Systems!

Norgren’s advanced cushion design features a unique, one­piece, nitrile compound seal that is captured within a
precision machined groove. This allows both linear
and radial “float” of the cushion seal which
virtually eliminates problems associated
with misalignment. Integral flow paths
molded in the periphery of the seal provide
exceptionally fast “out of cushion” stroke
reversal without the use of ball checks.

Series A & EA, NFPA Aluminum Decel-Air Cushioned Cylinder
Series J & EJ, NFPA Steel Decel-Air Cushioned Cylinder

Explanation of Decel-Air Cushion:

Norgren’s Decel Cushioned cylinder was designed for
applications where high velocity, low mass, material transfer or
machine function is required, and where the kinetic energy to
be absorbed during cushioning exceeds the parameters of our
standard Series EA or EJ air cylinders equipped with non­adjustable or adjustable cushions. Decel cushions employ
longer-than-standard air cushions to assist our Impact
Dampening Piston Seal.

Why does our Decel-Air Cushion work?

The extra cushion length of the Decel cushioned cylinder
provides an additional deceleration capability to slow the
cylinder’s moving mass to a point where the positive
cushioning effect of our Impact Dampening Piston Seals can
perform the final cushioning.

Norgren’s Decel-Air Cushioned Cylinders

Versus

Cylinder Mounted Shock Absorbers

The first extensive evaluation of pneumatic cylinder cushion
performance was undertaken by the Mechanical Engineering
Department of The Ohio State University. The test was
conducted on 2-1/2” bore, 12” stroke.
The OSU tests found the Decel Cushioned cylinders absorbed
almost three times as much kinetic energy with a lower level of
peak cushion as a standard Ecology seal configured cylinder.

Because air is compressible and is exhausted out of the
cylinder each cycle, the internal heat buildup is minimized. The
“Maximum Inch Pounds Per Hour” rating which is essential in
determining the effectiveness of shock absorber performance
is not needed to judge Decel cushion performance.

The test indicated that Norgren Decel-Air Cushioned cylinders
could prove to be superior to a hydralic shock absorber
assisted cylinder for high cycle, high velocity applications with
light to moderate loading (precisely the area where most
severe cylinder applications exist). The cycle rates and the
cushioning times of the Decel-Air Cushioned cylinders and the
hydraulic shock absorber assisted cylinders were
comparable.*

Decel-Air Cushioned cylinders are also less costly than shock
absorber mounted cylinders and are self-contained units.

*For comparative evaluation, a well-known hydraulic shock
absorber was chosen. The OSU tests showed a smooth shock­absorbing operation was achieved at very low velocities using
the shock absorbers, but at comparable Decel Cushion cylinder
velocities, a high mechanical impact took place on the shock
absorber mounted cylinder.

Piston Rod Diameter Selection:

Applications requiring long extend (push) strokes may require
oversize piston rod diameters to prevent buckling.
To determine the correct rod diameter for your application
follow these simple steps:

1. Select the thrust from the Cylinder Force and Volume Chart
(page ACT-1-13) that is required for your application.
Thrust = Piston Surface Area x Operating Pressure

2. From the Cylinder Mounting Diagram Chart
(page ACT-1-15) select the mounting style being used.

3. With the piston rod fully extended, calculate the value of L (in
inches). Multiply cylinder stroke by appropriate stroke factor
located in Cylinder Mounting Diagram Chart to obtain
effective length L.

4. Locate the value of L (in inches) from the Determining
Adequate Rod Diameter Chart.

5. Selecting Stop Tubes: Stop tubes enhance the transverse load

carrying capability of a long stroke cylinder by increasing the distance
between the piston and rod bearing at full extension (Refer to page
ACT-1-87). When the value of L (calculated from the Adequate Rod
Diameter Chart) is less than 40", a stop tube is not required.
However, if L is 40" or more, 1" of stop tube is recommended for every
10" (or fraction thereof) over 40".

6. Recommended Mounting Styles for Maximum Stroke and
Thrust Load:

• Multiply cylinder stroke by appropriate stroke factor to obtain
effective length L.

• If cylinder has extra rod extension, add this extension to the stroke
length before obtaining effective length.

Tie Rod Tightening:

In order to reduce the possibility of cylinder binding or damage,
tighten to quarter unit increments of the final torque value in the
following order: #1, #2, #3, #4.
Then torque fully to the recommended foot pounds in the same order.

Determining Adequate Rod Diameter Chart

Note: In some cases it may be necessary to use a larger bore cylinder than is required

for force in order to obtain an adequate rod diameter.

Breakaway Pressures

An average of 5 pounds (psig) is necessary to breakaway non­cushioned Series J air cylinders when mounted horizontally
with no load on the piston rod. Double rod end cylinders
require an average of 7 pounds (psig).

An average of 6 pounds (psig) is required to breakaway single

rod and Series A & J and Series EA & EJ air cylinders
equipped with optional non-adjustable air cushions. Double
rod end cylinders require an average of 8 pounds (psig).

These figures are for non-cushioned
cylinders with strokes of 6 inches or
less with factory lubrication. Consult
the factory if your application requires
a lower breakaway pressure or a
guaranteed minimum breakaway.

Series A & J cylinders with 3-1/4" thru
12" diameter pistons are counterbored
to provide a larger area for the
pressure
to act upon.

Listed are the average breakaway
pressures in PSI for all Series J & EJ
Cylinders. If your application requires a
lower breakaway pressure than
indicated for a particular bore size,
consult the factory.

Breakaway Pressures in PSI

Note: Breakaway pressures were established with
the cylinders mounted horizontally and no load on
the piston rod.
