Tie Rods: High-strength steel
maintains uniform compression on
tube end seals.
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.
Rod Seal: Nitrile lip-type seal is
pressure energized and wear
compensating for durability
and long life.
Rod Bearing: External removable
steel bearing housing (black oxide
finish), with an oil-impregnated
sintered iron rod bearing.

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.
Impact Dampening Piston Seals:
Our impact dampening piston seals, in
conjunction with our advanced cushion
design, decelerate and reduce
end-of-stroke noise.
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.
O-Ring Tube Seal: Buna is standard.
(Viton is optional.)

Adjustable Captive Cushion Needle
(not shown): Fine thread allows
for safe and precision adjustment of
cushion. (See page 2.)
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.
Piston Rod: Hard chrome plated
high-tensile steel, ground and polished.

Head/Cap: Precision machined from
alloy aluminum, then anodized for
corrosion resistance (black finish).
Wear Ring: Reinforced Teflon
®
compounded with polyphenylene sulfide
provides supreme wear and excellent
bearing support.
