Overview

Introduction
Our concept is to offer our customers a large variety of hydraulic cylinders at reasonable prices and prompt
deliveries. We offer quality construction on all cylinder models, with bore sizes ranging from ¾” to 24”. Operating
pressures range from 2000 PSI to 10,000 PSI. There are no restrictions in stroke, and we have many styles and sizes
of mounting types to choose from. Our cylinders are divided into different model series, each with its own unique
characteristics to suit a wide variety of applications.
To achieve our price and delivery goals, cylinder accessories and components such as pistons, head glands, rings,
mounts and others standard parts, are manufactured in large quantities on our CNC machines and stocked in our
warehouse. As a result, only the barrel and rod need to be made to order.
We will also manufacture custom cylinders to our customers requirements.

Quality
Our experience, engineering and quality manufacturing are the main features of our cylinders. It is the responsibility
of all our employees to maintain the high quality that our customers expect. Every cylinder is tested at its rated
pressure, and cycled through its stroke, and the basic dimensions are confirmed. We are currently in the process of
ISO 900 certification.

Mountings
Mountings such as trunnions, flanges, clevises, and spherical bearings, are welded to the barrel, or blind end of the
cylinder. Similarly, mountings are threaded or welded to the rod end.

To eliminate side loads, the axis of the cylinder must be aligned to the axis of the attachments. For the welded
accessories, this is accomplished by using a ¼” diameter spring pin inserted into machined centering holes that are in
the accessory and the end of the barrel. For the threaded accessories, the thread is machined accurately to the pin axis
to ensure concentricity to the rod. To reduce side loads, we recommend using spherical bearing mounting.

Since we manufacture the barrel and rod to order, any size and type of accessories shown can be supplied with any of
our cylinders, allowing an abundance of choices. Special mounts can also be manufactured.

Cushions
There are many ways of reducing the momentum of a cylinder load at the end of the stroke. A cost effective method
is to reduce the flow of oil near the end of the stroke by means of a plunger or cushion. This cushion can be fixed, or
adjustable. We offer fixed cushions because of their simplicity. Cushions can be supplied for the rod end, blind end,
or both ends. Cushions are standard for Series EX and TH. They are optional for Series B and TM.
We do not, as a standard, offer cushions for any other series of cylinder.

Overall Length
If necessary, the overall retracted length of a cylinder can be increased by:
• Adding a stop tube between the piston and the head gland.
• Adding an extension to the blind end of the barrel.
• Increasing the rod extension.

Overview

Rod Specifications
Standard rod material is CPO (C1045 steel with 0.0005 thick hard chrome plating). We also offer IHCP
(Induction hardened chrome plated) or else stainless steel SS (S316L stainless with 0.001 thick hard chrome) as
readily available options. Rod accessories can be welded or threaded to the rod. Usually, a female thread is
recommended over a male thread because a broken end can be easily replaced as opposed to changing a rod that
had a male thread. Also, a female thread can be converted to a male thread by using a rod stud (see page 02-16).
Note that the thread size is governed by the pin size “CD” of the threaded accessory being used on the rod end.

Proximity Switch
A high pressure GO proximity switch can be installed at the ends of the cylinder. This signals the extended or the
retracted positions. These are available as an option only on the series B and EX.

Valves
Valves such as directional, counterbalance, flow control and many others can be added to the cylinder in many
ways. We normally mount the valve in a manifold, and mount the manifold to the cylinder with SAE Code 61 or
Code 62 connections, and then run a steel tube to the other end.

Overview

Ports
Cylinder ports are machined into the barrel end and barrel ring. This eliminates the local distortion and stress
concentration due to welding a half coupling on the outside of the barrel. The result is a strong, clean cylinder
barrel. However, the downside is that because we pre-manufacture and stock these parts, changing the port size is
difficult. Therefore, it is more cost effective to use an adapter to change the port type and size.

Seals
All of our cylinders utilize the latest in seal design from major manufacturers. Seals are one of the most critical
components in a hydraulic cylinder. It is very important to keep the nearby operating environment as clean as
possible and to keep the oil as contaminant free as possible.

Our piston seals are carefully chosen to perform in the requirements of each individual series of cylinder. Most of
our piston seals will be of the “slipper” style, while the Series B offers the option of using a loaded “u-cup” style.
In general, u-cup seals are used where the cylinder must support a load without creeping. The slipper style of seals
offer low friction and are more tolerant of contamination. Materials range from hard plastic to urethane to glass
filled PTFE, all with nitrile energizers.

Our rod seals are a loaded u-cup style with back beveled sealing lips. They also have a greater depth than cross
section to resist roll over in the groove under pressure.

Our rod wipers are polyurethane either of the metal encased style or the snap in style. The metal encased rod
wipers are used on the Series B, EX and TH.

All wear rings are reinforced nylon.

All O’rings and backup rings are nitrile.

Thread locking compound

All threaded components of the cylinder should be assembled using a thread locking compound. This will ensure that
items such as head gland bolts and piston nuts stay tight. We use products such as Loctite Threadlocker. It is
important to closely follow the manufacturers instructions regarding cleaning and priming before applying these
threadlocking compounds.

Buckling K K
A major concern with long stroke cylinders under a B C B
compressive load is the buckling of the rod. This can be reduced
or eliminated by various means:-
K = B + C + A (2 X STROKE) K = B + F + STROKE
• Use a stop tube to increase the overlap between the piston PIN MOUNT FOOT MOUNT
and the head gland.
• Use spherical bearings to reduce eccentricity.
• Use a mounting style that will reduce the “K” dimension. K K

Introduction

Part number
For most accessories, we have organized the charts by the pin hole diameter ‘CD’ which is the controlling
dimension. The first set of numbers “Bxxxx” is our drawing number and describes the type of accessory.
This is followed by a dash number which is the size of the pin diameter ‘CD’ x 16 and will give the size of
the pin in sixteenths of an inch, eg. a 1” diameter pin is a “ –16”

Specifications
Unless otherwise specified, all accessories are manufactured from CSA G40.21-44W or AISI C1045 steel
and all dimensions are specified in inches. The strength of the accessories is based on the strength of a C1045
pin of diameter ‘CD‘. All male threaded accessories have an adjustable dimension of “LS”. The maximum
adjustment is “+ADJ”. This is based on three-quarters thread engagement.

Because our cylinder barrels and rods are always manufactured to order, any type and size of accessory is
available with any cylinder. Other barrel mounting types such as trunnions, flange mounts, and foot mounts
are given in the section pertaining to each series of cylinders. For any custom types and sizes not shown in
this catalogue, feel free to contact our engineering department.

Recommendations
The use of spherical bearings is recommended because they reduce side loads created by any mounting
misalignment. They are also easily replaced when worn or damaged.

If a threaded accessory is required, a male thread on the accessory is preferred to a female thread which
would use a male thread on the rod. Aside from buckling, the weakest part of a rod or accessory is at the
base of the thread. If it happens to break off, it is easier to replace an accessory than a complete rod.

Series B Cylinder – Introduction

Series-B is our standard heavy duty hydraulic cylinder. The bolt on head design and all welded
construction results in a simple and strong cylinder which is easy to assemble and disassemble. These
cylinders are a reliable choice for industrial, marine or mobile equipment applications.

• Pressure rating is 3000 psi (5000 psi non-shock)

• Ductile iron piston and head
• Rods are available in C1045 chrome plated or C1045 induction hardened chrome plate or 316
stainless steel chrome plated
• Cushions are available on either end or both ends
• SAE O-ring boss ports are standard
• Every cylinder is individually tested before shipment
• Wide range of mounting accessories and brackets

Seals
Series-B cylinders offer a choice of two types of piston seals:-
1) Loaded U-cup seals are preferable for cylinders which must hold a load without creeping.
2) Slipper seals are low friction seals preferable for cylinders that cycle frequently and are not required
to hold a load. They are more tolerant of contamination than a U-cup type of seal. These seals will be
provided as standard unless otherwise specified.

U-cup polyurethane rod seals provide dry rod sealing performance.

Metal-clad polyurethane wiper seals keep contaminants out of the cylinder.
Wear rings are reinforced nylon.
All o-rings and back-up rings are nitrile
All seals are good for a temperature range of -65F to +225F (-54C to +107C)

Mounting dimensions
Our cylinders conform to NFPA mounting dimensions with the following exceptions:
• NFPA clevis mounting "MP1" uses different dimensions within one bore size for different rod sizes.
We have one set of dimensions for all rods sizes in a given bore size. Our dimensions will agree with
one set of the NFPA dimensions. When the mounting dimensions are critical, check our dimensions
on the appropriate pages of the catalog for suitability.
• Front trunnion mounts conform to NFPA "MT1"
• Mid trunnion mounts conform to NFPA "MT4"
• Rear trunnion mounts NFPA "MT2" are not available.
• Front flange mounts are available in NFPA "MF1" and "MF5" and Sealum standard.
• Rear flange mounts do not conform.
• Foot mount does not conform.

Trunnion mounts
It is recommended to use female style mid-trunnions instead of male style. This way, if a stud happens to
break off , it will be the pin that actually failed and needs replacing. However when the stud fails on a
male style trunnion, the barrel will need replacing.

Series B Cylinder – Introduction

Double Rod Cylinders

All Series B cylinders are available in a double rod design. Double rods are used when the cylinder speed
must be the same in both directions. This is beneficial when the cylinder speed is used to meter the amount
of material or work flow that is moved with each cycle. Double rod cylinders can also be used to actuate a
second function with the other rod.

Back to Back Cylinders

All Series B cylinders are available in a back to back design. Back to back cylinders are useful when loads
must be moved in different stages. They are also useful when different sizes of loads must all reach the same
end point. With up to four cylinders combined, loads may be moved in four stages with one cylinder
installation.

Cushions
In certain applications it is desirable to stop the load gradually, as opposed to a sudden stop, at the end of
the cylinder stroke. This will protect the cylinder and the load being moved from damaging impacts at the
ends of the stroke. They are generally considered when the piston velocity approaches 25 feet per minute
(5 inches per second). A cushion will restrict the oil flow out of the cylinder to create a back pressure which
will oppose the force on the working side of the piston. This will decelerate the load smoothly avoiding
shock loads being introduced to the load or the cylinder at the end of the stroke. The overall result will be
less damage to the cylinder, load and any associated machinery, thereby reducing downtime and
maintenance.

A cushioned cylinder application will also be quieter when it comes to the end of its stroke and any mating
parts make contact. This will create a quieter working environment.

Fixed cushions are available at both ends or at either end.

Series TM Cylinder

Our Series TM cylinders, with suitable electronics, can monitor the position and velocity of the piston.
It is based on our popular Series B cylinder with provision for mounting an LVDT (Linear Velocity
Displacement Transducer) and magnet from Temposonic, Balluff, or any other manufacturer.

The transducer assembly is mounted into the blind end of the cylinder. The magnet is housed in a
stainless steel piston nut and the probe is inserted into a blind hole in the rod. The rod is drilled from one
end only, which makes for a much stronger rod end than one that is drilled from both ends. A male
thread is standard for the rod end. Therefore, any size and style of accessory with female threads is
available. Female threads in the rod end can be accommodated, but the rod extension must be increased
by the depth of the threads.

The transducer head is protected by a sealed housing. Since the back end of the cylinder must be clear
to withdraw the probe, the available mounting styles are front and mid trunnion, front and rear flange
and foot mount.

The pressure rating is 3000 psi operating and 5000 psi non-shock and fixed cushions at both ends of the
cylinder are standard with series TM.

Options are available to mount a wide variety of servo or proportional valves on the cylinder. See page
#27-7 of the manifold section for details.

Temposonic housing

Temposonic probe housing

This is a complete Temposonic measuring device. It can be mounted to any type of machinery where one would
want to measure the movement. With this arrangement, the moving piece of machinery would pull the rod out,
while the barrel is stationary. The Temposonic feedback device will then send out a signal which can be trans-
lated into the machine position.

Series TH Cylinder

Upgrades
We have recently upgraded our thumb cylinder design. They are now rated for a 5,000 PSI working pressure
(7500 psi non-shock) to accommodate the higher pressures used on modern mobile equipment. The old and new
cylinders are interchangeable with each other, as they have the same mounting dimensions and porting. The new
cylinders have thicker walls, larger bolts on the head gland and longer cushions. Parts will still be available for the
older style cylinders.

Series IT Cylinder

Our Series IT hydraulic cylinder is designed for simplicity and economy. With a 2,500 psi working pressure and
a 3,500 psi non-shock load pressure we have not compromised on the quality, yet have made it an affordable and
reliable alternative as opposed to using our more rugged bolted on head gland construction style of hydraulic
cylinder.

To strengthen the open end of the cylinder, a thick ring is welded to the barrel to carry the internal thread and
port. Both ports are machined into the cylinder barrel end and ring, which means localized weld distortion and the
stress concentrations that arise from welding half couplings for ports are eliminated. The internal threads that hold
the head gland will not corrode since they are constantly submersed in oil. The piston is securely threaded and
adhesive bonded to the rod. To accommodate our customers wide range of needs, we manufacture the barrel and
cylinder rod to order on every hydraulic cylinder order to provide the exact strokes and pin to pin dimensions that
are required. A variety of mounting accessories can be installed onto the cylinder to suit virtually any application.
Other rod materials and mounting styles, such as trunnion and flange mounts, are available on request.

Series MIT Cylinder

Our Series MIT is our Miniature Internal Thread hydraulic cylinder. It’s a welded construction cylinder with an
internal threaded gland rated for 3,000 psi working pressure and 4,000 psi non-shock pressure.

To strengthen the open end of the cylinder, a thick ring is welded to the barrel to carry the internal thread and
port. Both ports are machined into the cylinder barrel itself, which means localized weld distortion and the stress
concentration that arises from welding half couplings for ports are eliminated. The internal threads that hold the
gland will not corrode since they are constantly submersed in oil. To accommodate our customers wide range of
requirements, we manufacture the barrel and rod to order for every hydraulic cylinder to provide the exact stroke
and pin to pin dimensions as required. Various combinations of mounting accessories can also be installed onto
the cylinder to suit most applications. Other rod materials and mounting styles as needed, such as trunnion and
flange mount, are available on request.

All MIT cylinders have National Pipe Thread (NPT) ports. The blind end port is normally placed at 90° to the
center-line of a fixed pin axis, at the 12 o‘clock position. The clevis style of blind end always has two ports, one
in line with the rear port and one that is at 90° to this port.

Whenever possible, spherical bearings mounts should be used on both ends of the cylinders. This will reduce any
mounting misalignment and side loading that may be introduced into the cylinder. This type of loading should
definitely be avoided on cylinders with small diameter rods such as used on this series.

Series SIT Cylinder

Our Series SIT is a Single acting Internal Thread displacement cylinder. With a pressure rating of 2500 psi
working and 3500 psi non-shock, the pressure acts on the rod to create an extend force that is equal to that of
the pressure times the rod area. An external force, generally gravity, retracts the rod once the oil is allowed to
leave the cylinder. The piston supports and guides the rod.

The cylinder is well sealed at the rod end which will keep the inside of the cylinder barrel from becoming
contaminated. The advantage of this design is that the inside of the barrel is not exposed to atmosphere and the
rod is always immersed in oil when retracted which will keep the rod from corroding. Also, only one hydraulic
pressure line is required in order to operate the cylinder, thus simplifying the hose routing.

Since pressure acts on the area of the rod and not on the piston area, it is necessary to use a larger bore than a
non-displacement type of cylinder design to exert the same force.

There is a 1/16” NPT plug at the rod end of the cylinder barrel which is provided to bleed air out of the
cylinder during installation. This must be done in order to prevent the cylinder from becoming “spongy” due to
the compressibility of the air trapped inside the cylinder.

Series LB Cylinder

Our Series LB is a large bore double acting cylinder. They have a 3,000 psi working pressure rating
and a 4,000 psi non-shock pressure rating. They are designed for a multitude of applications where a
large force is required. Higher working pressures are available on request.

FEATURES:
• The head gland is held in place with a threaded ring. This makes for simpler installation and removal.
• A thick ring is welded to the end of the barrel. This ensures that the barrel end will not expand under
pressure, causing seal leakage or the threaded ring to loosen.
• The piston is fastened to the end of the rod with a ring of bolts. This provides for easier installation
and removal than if the piston was threaded on or held with one large nut.
• C1045 hard chrome plated rod. May be hollow in larger sizes.

Series J Cylinder

Pancake style cylinder

The pancake cylinders are meant for short stroke straight lift applications. They are a single acting
cylinder operating at 10,000 psi. and would generally be operated by a manual pump. The rod is
inserted directly into the barrel without any head gland holding it in place. As such the operator must
be careful not to pump the rod out of the barrel. There is a line machined into the rod to mark the
safe limit of the extension. A carrying handle is standard. Strokes are either 1” or 2” only.

These cylinders are ideal for construction work, machinery lifts and emergency rescue work.

Telescopic Cylinder – Introduction

A telescopic cylinder is essentially a series of cylinders (called stages) nesting inside one another. It is normally
used where space is a constraint.

Each stage is the rod of the larger stage and the barrel of that stage. e.g. A 3-stage cylinder is 3 stages or rods
that move in and out. It consists of the barrel (the largest tube) followed by the first stage and then the second
stage and finally the smallest stage (called the rod).

There are two types of telescopic cylinders. Single acting and double acting.

Single Acting - S/A

A S/A telescopic is essentially a displacement cylinder. It extends by hydraulic power and retracts by gravity or
any external force. The oil pressure acts on the outside diameter of the various rods. When retracted, the
various stages are immersed in oil, thus protecting them from rusting. These cylinders do not leak unless the rod
seals are damaged. The port is located at the barrel end and a bleed port at the rod. The cylinder is sealed at the
rod end.

Double Acting - D/A

D/A telescopic is powered both ways. Oil acts on the bore area to extend and on the annulus area between the
bore and rod to retract. The extend force is typically 5 times the retract force. Because of this intensification, it
is critical that the retract port is not restricted. D/A cylinders will slowly drift due to seal leakage; the leakage
rate is
dependent on the surface finishes of the cast iron piston seals and the barrel surface. The ports are located at the
rod end. The first stage extends first, when extending the cylinder; on retracting, the rod stage retracts first.

Design & Selection Considerations

• The forces given in the charts are theoretical; friction and back pressure are ignored.
• Since the size of each stage is different, the speed and force of a cylinder will vary as the cylinder extends
and retract. For a variable load application (e.g. dump truck), the force at each stage must be examined for
overall suitability.
• Overlap “A” should be maximum for strength. We recommend a minimum of 15% to 20% of the stroke per
stage. A telescopic cylinder should be designed to use the fewest number of stages, for economy and
strength.
• As the customer is aware of all aspects of the application, he is responsible for sizing the cylinder according
to his needs. Our products are not warranted express or by implication for any specific purpose,
notwithstanding any disclosure to us of the use to which the product is to be put.
• Stroke is the same for each stage. The rod stroke can be different to accommodate an odd stroke.

Telescopic Cylinder – Introduction

Features
• Designed for 3,000 PSI non-shock pressure.
• Designed for easy maintenance. Unscrew the barrel end cap and each stage can be removed from the blind
end.
• All stages have 0.001 inches thick hard chrome on the O.D. to resist corrosion. This smooth surface reduces
wear on the rod, wear ring, seal and wiper.
• No external threaded ring at the rod. Each stage protrudes only ¼” resulting in maximum overlap.
• The tube of each stage is re-inforced by the gland and piston, making the stages considerably stronger.
• Wide selection of standard mounting. The following charts show the standard size (hole diameter, CD) and
x-hole and tube eye style. Any other style and size (shown in the accessories section ‘02’) are available.
The limitation is that the rod end accessory must be smaller than the rod for welded type. If this is not
possible, then a threaded type must be selected.
• The annulus space between each stage is 1/8” this gives a smoother transition between stages when
extending and retracting. Also, the cylinder diameter is smaller.
• The rod seal is “U-Cup” (Parker or equivalent) and not Vee packing which can be over-tightened causing
increased friction and premature failure.
• Normally three wear rings, strategically placed, support each stage. Two wear rings style is available but is
only recommended for short stroke cylinders (less than 10” of S/S). Call our Engineering Department for
details.
• SAE ORB (O’ring Boss) ports are standard.

Cylinder Attachments
Blind End
• The following charts show the blind end with standard tube eye.
• Any size and type of welded cylinder accessories can be ordered.
• Front flange, rear flange, male trunnion and female trunnion are also available see page 13-13, 14 for
details.

Rod End
• The following charts show X-hole mounting as the shortest and simplest style.
• Any other types or sizes can be supplied. The only restriction is, the attachments must be smaller than the
rod diameter.
• If a bigger accessory is necessary, it must be threaded on. Consult our Engineering Department for details.

Selection
First, decide on the following:
• Working pressure.
• Single or double acting cylinder.
• Force and stroke requirements.
• Space available.
• Type and size of attachments at both ends to support the load and minimize side loads.

From the following charts work out:

• Number of stages.
• S/S – stroke per stage
• A – overlap

INDUSTRIES LTD. SERIES SS Web: sealum.com

The design of the Series SS cylinder is similar to our standard Series B

All cylinders are designed with standard pistons, heads, ends and rings. The barrel and rod are
made to order to allow complete customization of stroke. Stop tubes, barrel extensions, and rod
extensions can be used to adjust the OAL.
Cylinder model numbers are only created after an order is placed and are tracked using H
drawing numbers. The H number refers to a specific customer design and are not shown in this
catalogue.
Model # e.g. SS29-20.8-09-H5028 DWG #
SERIES SS ROD DIA X 10

BORE SIZE X 10 STROKE

Key Points:
• Rod Material is Stainless Steel 17-4PH condition H1150, with 0.0005” to 0.001” hard chrome to
provide a smooth and hardened surface for the rod seal and wiper.
• External components are made from 316L SS
• Cylinders are not painted
• Recommend spherical bushings both ends to reduce side loading from misalignment and decrease
the likelihood of buckling. It is responsibility of the customer to select an appropriate rod size,
stroke, stop tube, and load to avoid buckling.
• All ports are SAE O’Ring Boss and are machined directly into the end and ring. SS fittings should be
used to adapt to other connections.
• SS mounting attachments are standard in three pin sizes ½”, ¾”, and 1” and can be seen on the last
page. These attachments are also available for use on the customer’s equipment.
• Round body and no protrusion is ideal for anti corrosion.
