Norgren NFPA Aluminum & Steel Cylinders - Manual (Page 2)

ACT-1-2 Brookville, OH USA Phone 937-833-4033 www.norgren.com
Series A, NFPA Aluminum Air Cylinders (ø1-1/2" to 8"), Cylinder Features
Ultra Cushion ® Seals: Advanced
design features a unique, one-piece,
compound seal of nitrile* captured within
a precision machined groove. Linear and
radial “float” of the cushion seals
eliminates misalignment. Ultra Cushions
provide exceptionally fast “out of
cushion” stroke reversal. (Head and Cap
Cushions are optional.)
*Nitrile seals on the 5/8" & 1" rod diameter.
For rod sizes 1-3/8" and larger, urethane seals are standard.
O-Ring Tube Seal: Buna is
standard. (Viton is optional.)
Cylinder Tube: High-strength
aluminum alloy ideally suited for air
service. The tube is clear anodized on the
O.D. and hard anodic coated on the I.D.,
resulting in a smooth, file hard (60RC),
corrosion and score resistant
surface finish.
Tie Rods: High-strength steel maintains
uniform compression on tube end seals.
Piston: Machined solid aluminum
alloy, light-weight for low inertia, yet
strong. Threaded piston is installed with
high strength threadlocker adhesive then
staked to the piston rod.
Adjustable Captive Cushion
Needle: A one-piece, precision threaded
brass cushion adjustment screw with a
threaded steel capture ring. It provides
safe and precise cushion adjustment. 6
Piston Seals: Long-wearing
nitrile seals.
Wear Ring: Reinforced Teflon ®
compounded with polyphenylene sulfide
provides supreme wear and excellent
bearing support.
Standard non-cushioned Series A cylinders are
recommended for applications that require full
bottoming of the piston and where the noise
emitted by the metal-to-metal impact between the
piston and cylinder end caps is tolerable. We
recommend that optional non-adjustable cushions
be added for piston speeds (moving light tools)
ranging from 15 to 30 in/sec. For speeds exceeding
30 in/sec, the cylinders should be equipped with
adjustable air cushions.

Piston Rod: Hard chrome plated
high-tensile steel, ground and polished.
Rod Bearing: External removable
threaded steel bearing housing (black
oxide finish), with an oil-impregnated
sintered iron rod bearing.
Rod Seal: Nitrile lip-type seal
is pressure energized and wear
compensating for durability and long life.
Head/Cap: Precision machined from
alloy aluminum, then anodized for
corrosion resistance (black finish).

Wiper Seal: Lip-type urethane
wiper seal keeps contaminates
from getting into cylinder by
aggressively wiping foreign materials
from the piston rod, enhancing the
rod seal life.
Application Information

The addition of a Teflon ® wear ring to the
outer perimeter of the piston permits us to
guarantee its operation against failure due
to lack of lubrication for ONE FULL YEAR,
regardless of cycles! See page ACT-1-98 for
complete warranty.
