A Buna N 90 Durometer "O" ring is LOCTITED™ to
the front head and/or rear cap surface to prevent metal to metal
contact. Each bumper increases the cylinder length. Consult factory
for bumper diameter. When ordering please specify bumper front
head, rear cap or both ends.

Spring Return or Extend |
|
This light duty spring cylinder is available with a 3" maximum
stroke and a rod diameter of 1" or less. The cylinder length
will be 1" longer than standard and have an approximate
10 pound pre-load with a spring rate of approximately 10 pounds
per inch.
|
|
Fail-Safe Spring Return |
|
The cylinder provides fail-safe retraction, if air pressure is
lost, with a heavy duty high force spring. It is available in
certain models of the Series B and all Series J cylinders. Consult
factory for specifications.
|
|
Hollow Piston Rods |
|
They are available on Series B cylinders only. Standard sizes
are: 3/4" diameter piston rod with a 1/4" diameter
thru hole and 1" diameter piston rod with a 7/16" diameter
thru hole.

Phenolic Rod Bushings |
|
Phenolic material is a hard, dense laminated thermoset plastic
produced by applying heat and pressure to layers of a fine weave
cotton fabric reinforced with a phenolic binder. Phenolic is
generally not attacked by common solvents such as alcohol or
petroleum products and resists low concentrations of mineral
acids (except nitric and chromic). However, in cases of chemical
attack by acids such as nitric and chromic, the material retains
its strength and may have a long and useful life. Phenolic offers
excellent resistance to fruit acids. The material may be used
continuously at 200°F.

|
Rod Boots |
Rod boots are used for added protection from environmetnal conditions.
Material is Neoprene/Nylon .050-.060 gauge with an operating
temperature of 0°F to 200°F.
NOTE: Rod extension increases 1" in length for every 3"
of stroke. Makimum stoke is 24".
Not available on I 11/2" bore, Model B120, or Series R cylinders.
Design changes for 1 3/8" & 1 1/2" rod diameter.
|
|
Adjustable Stroke |
The adjustment is suitable for infrequent adjustments in the
reduction of stroke length in the retracted position.
Length of adjustment must be specified when ordering.
Rear cap cushion is not available.
Steel plate may not be the same square size as rear cap on larger
bore cylinders.

Stop Tubes
A stop tube is a spacer placed between the piston and the rod
end head to reduce bearing loads. The reduction in bearing load
is done by increasing the distance between bearing surfaces.
Stop tubes are recommended for mounting types I and II any
time the "L" dimnsion of that application exceeds 40".
Stop tubes are normally not required with mounting types II
I and IV but the designer should use his own discretion to keep
bearing loads to a minimum. Stop tubes should be specified at
a rate of 1" for every 10", or fraction thereof, over
an "L" dimension of 40".
Adjust "L" dimension by adding stop tube length when
using "L" to determine rod diameter.
Note: Increasing rod diameter to reduce bearing load is not
recommended. Stop tubes are more effective and generally more
economical.
