Piston rods through 4" diameter have a minimum expected yield of 100,000 psi. They are case hardened to 50 Rockwell C to a depth of .030" for damage resistance. They are then hard chrome plated for wear and corrosion resistance. Larger diameter rods have an expected minimum yield of 50,000 to 60,000 psi depending on diameter and are hard chrome plated.

Offers much longer fatigue life through elimination of thread relief stress concentration point. Standard as Style 2 rod end on all rod sizes through 2

/2" diameter. Studs are pretorqued and locked in to prevent loosening. They are machined from high tensile steel and the threads rolled.

The steel tube is honed to an 8 to 16 microinch finish for low friction and long seal and piston bearing life. Tube ends are machined on the O. D. concentric with the I. D. They are confined by the close tolerance machining of the head and cap which provides greater hoop strength.

Maximum strength is obtained through a prestressed tie rod assembly.

Four wrench flats are provided as standard for easy attachment. Spanner holes, in lieu of flats, are standard on large diameter rods.

All pistons are machined from a fine grain alloy cast iron. They are threaded directly onto the piston rod, torqued, sealed and locked in place with one or more set screws.

The special piston seal is an endless glass filled Teflon material with an O-ring expander. One or more (depending on bore size) bronze filled Teflon bearing strips are also employed on this type piston to eliminate metal-to-metal contact. This type piston offers long life, low friction, near zero leakage, and great tolerance for side loading. It can be used successfully on virtually any application.

Pressure activated O-ring seals are used at rod gland and tube ends. Located to eliminate extrusion and to provide positive leak tight seal.

High load bearing bronze piloted into the head. Located inboard of the seals to insure a well lubricated bearing for the fastest cycling applications. It need not be removed for rod seal replacement.

The polyurethane wiper is designed to wipe off abrasive dust and contaminants on the retract stroke to insure long life for packings, rod bearing, and piston rod. Where the rod will be exposed to gummy materials such as road tar, a metallic rod scraper is available.

The polyurethane rod seal has a unique design which incorporates the optimum sealing properties of a U configuration with the elastomeric properties of a compressiontype seal. The polyurethane material was selected for toughness, abrasion resistance, and the ability to resist extrusion under rough service conditions.

Cushion pistons (29) are tapered to provide gradual deceleration and eliminate shock upon entrance. The Adjusting Screw with fine threads (30) provides a wide range of adjustment.

When required, air bleeds are located where they can be employed most successfully – at the tube and head juncture. The straight thread plugs are equipped with metallic O-rings so they can be used repeatedly with a good seal every time.

Easily removable for replacement of rod seal and wiper. In most cases it is not necessary to demount or disassemble the cylinder. Easier to service since on removal of the ductile iron gland, the piston rod remains supported by the separate rod bearing.

For 7" bore cylinders and larger, the tie rods are given an initial torque, the tie rods are heated, and then the tie rod nuts are turned a calculated amount. First torque all 4 tie rod nuts to 200-250 foot pounds. Measure the cylinder to obtain length L, consult the chart for the proper number of turns or fractions (in 12ths). The figures in Column 1 shown in 12ths corresponds to the points and flats of the hex nut (see illustration). The piston rod of the cylinder should be either fully retracted or fully extended prior to heating. Place an asbestos sheet between the tube and tie rod and heat to 800°F for as long a length as possible. When the distance between the cylinder heads is 18" or less, do not heat closer than 3" of either head. Tie rods should be heated and tightened in cross corner rotation and in steps up to full tension. Allow the tie rods to cool before testing or installation.

Cushions

Sheffer pioneered tapered cushions, designed to provide gradual deceleration and eliminate shock upon entrance of the cushion pistons, have now been considerably improved. The tapered cushion has been married with a fine thread, wide range, adjusting screw. This new combination offers a positive, low-shock deceleration and a method to adjust the cushioning effect for speeds and loads.

The adjusting screw is identified by a tag affixed to the head (or cap) and can be further distinguished by the fact that it is captivated with the Sheffer exclusive captivator This allows full open to close adjustment without concern for damaging seals.

The cushion check, which does not require adjustment, has a single slot in its head. It does not project beyond the surface of the head (or cap). The cushion check plus the tapered cushion piston provides rapid acceleration out of cushioning. There is no spring in the cushion check to fatigue, hence, no worry of mechanical failure.

Cushioning is designed to properly cushion the cylinder and is not intended to cushion large inertia loads. Cushions do not substitute for speed controls or deceleration valves on most installations.

As indicated on page HH-6, the standard positions for ports are 1 and 5. Where possible, the standard positions for cushion adjusting screws will be 2 and 6 and the standard positions for cushion checks will be 4 and 8. With some mounting styles, it is not possible to so locate the adjusting screws and checks. For example, a Trunnion Front Mount has the trunnion pins located in positions 2 and 4 on the head. With the port in position 1, the only side available for both adjusting screw and check is position 3. Since both will then be located on the same side, they will be located off-center. This example would hold true with the TR, CL, FHF and RHF mounts. See Chart A for standard positions that will be supplied unless otherwise specified. When requested, other positions can be supplied so long as there is no interference with mounting.

Where access to an adjusting screw or check could be made difficult because of proximity to a mount, the locations of the screws will be slightly off-center. An example of this would be a small bore cylinder with a side lug mount.

Pressure and Shock

HH SERIES Cylinders are suitable for working pressures to 3,000 psi and maximum pressure including any shock to 5,000 psi. Refer to

Chart B for the

maximum operating pressure that can be used with a 3:1 safety factor based on yield. It is felt that this is an adequate safety factor for any well designed hydraulic system where shock conditions have been considered and reduced to an acceptable level. Not all mounting styles will take the thrust generated at these pressures. See separate Accessories Brochure.

The following factors in shock loading

should be considered:

n Relief valves in the circuit do not

protect the components from shock because of the time lag.

n Gauges do not necessarily register

shock conditions, either because of their position in the circuit, or the short duration of shock.

n The two general types of shock

loading to be considered are pressure rise caused by quick stop of the flow in the circuit and quick pressure drop. Decompression shock is particularly important in large bore cylinders and can be as destructive as compression shock.

n The magnitude of the pressure

difference and the duration that the maximum pressure exists are the factors that determine the damage from shock.

Tandem Cylinders and Multi-stage Cylinders

The tandem cylinder (Figure A) has two pistons connected to a common rod, resulting in twice the force output of a single cylinder. Multi-stage cylinders

(Figure B) offer multiple, positive

strokes by pressurizing one cylinder, the other, or both. Contact the factory for other variations.

Rod Gland Drain Back

When not even a drop of external leakage can be tolerated, the rod gland drain back provides a signal that the rod seal set has worn to the point of replacement – without the danger of contamination from leakage.

External Rod Seal

When a cylinder is to be operated under water, provision is made to prevent the water from being drawn into the cylinder at the time of valve shift or pressure differential.

Stainless Steel Piston Rods

Many applications, especially those subjected to water spray, require the use of stainless steel piston rods. We stock AISI Type 304 hard chrome plated, stainless steel and will furnish that type unless otherwise specified. Type 304 is considered a good, corrosion resistant type of stainless steel, but the minimum expected yield is approximately 35,000 psi and that factor must be considered with respect to operating pressure, column loading, etc.

FIGURE B

FIGURE A

Adjustable Stroke

Shown is an integral stroke adjustment (externally adjusted) that is accomplished by the use of a bump rod threaded into the cylinder cap. Seals are incorporated to prevent external leakage and a lock nut is included.

Thrust Key

All side mounted cylinders (SF, FB, EL and SL mounts) can be supplied with thrust keys. Thrust keys are available in bore sizes 1

/8" thru 6". Extending the rod gland retainer, as shown, provides a key which fits into a milled slot in the mounting surface of the machine member. Combined with the mount this key assures that cylinder will not shift in severe service.

Spherical Bearings

Pivot mounting brackets and rod eyes can be provided with spherical bearings to compensate for misalignment on both ends of cylinders. Consider also the use of the Sheffer Uni-Lign described in separate Accessories Brochure.

Non-Rotating Piston Rod

Two methods of providing nonrotating piston rods are employed. The internal rod type

(Figure A)

is generally used since it requires less space and is neater. The type shown in Figure B must be used on small bore cylinders where internal space is limited.

Port Sizes - Standard ports are S.A.E.

and sizes as shown in Column 5 on the adjacent chart. Unless otherwise specified, those sizes are what will be furnished. Smaller than standard ports can be supplied at no extra cost. It is recommended that cylinders be ordered with ports no larger than needed so that the trouble and expense of obtaining and installing reducing fittings can be avoided. At a modest cost, larger than standard ports, as shown in COLUMN 6, can be furnished. While these larger ports can be put in a standard cylinder, it is necessary in some cases to slightly alter the Y and the P dimensions shown on our mounting dimension pages. Contact the factory for those dimensional changes.

S.A.E. Straight Thread Ports - This

type of port offers positive seal with full thread engagement. It also eliminates the problem of faulty pipe threads since sealing takes place independently of the thread. No messy pipe dope to bother with or to contaminate the hydraulic system. No wedging, distortion, or breakage due to over-tightening. Alignment and full sealing are both assured since the fittings can be tightened after lining up. Straight thread fittings may be reused, indefinitely. COLUMN 6 shows the maximum size of S.A.E. port that can be furnished in a standard cylinder. Larger sizes accommodated with special heads and caps.

S.A.E. Flanged Ports - At a slight

additional cost, flanged ports can be provided. COLUMN 7 shows the maximum standard S.A.E. flange sizes available.

Air Bleeds

An air bleed may be ordered at either or both ends of the cylinder as an option. To provide for maximum bleeding of air from the cylinder, Sheffer places its air bleeds in the tube to bleed air from the tube/head or tube/cap juncture. The air is bled from the cylinder by backing out the straight thread metallic seal plug to allow air to pass by the threads. When air bubbles stop and oil starts to flow, retighten plug. It is recommended that bleeding be done with pressure on the opposite end of the cylinder so that the bleed plug is not subjected to pump pressure when being backed out. Air bleeds should always be positioned at the highest point of the cylinder tube. Please specify positions of air bleeds by position number from the chart.

NOTE: Since Sheffer puts air bleeds in the cylinder tube, position can be changed by loosening the tie rods and rotating the tube. Photos and Line Drawings show ports in positions 1 and 5.

There is a construction variance in the 11/8", 11/2", 2" bores, the 21/2" bore with a 13/8" or a 13/4" rod, and in the 31/4" bore with a 2" diameter rod. On the Front Flange (FF) and Front Flange Extra (FFX) Mounts, in these sizes, the round retainer shown above is not used. The tie rods thread into the flange, and the flange serves as the rod gland retainer. Hence, in these sizes, the gland cannot be removed without loosening the tie rods. The basic cylinder dimensions shown above do not change.

On the Front Head Flange Mount (FHF), in the 1

/8", 11/2", the 21/2" bore with a 13/4" rod, and the 31/4" bore with a 2" rod, the retainer is the same rectangular size as the head. Tie rods thread into the retainer and the retainer holds in the packing gland. Hence, in these sizes the gland cannot be removed without loosening the tie rods. Dimensions for these sizes of the FHF mount cylinders can be obtained from the Front Flange Mount (FF) charting. Mounting bolts will clear through both the flange (FF dimension) and the head (G dimension).

Good – Front Flange Mount

While this style of mount is a widely used one, its use should be restricted to pressures under 1000 psi, short strokes (under 36") and standard rod diameters. Note that the Front Head Flange mount has the same mounting hole pattern.

Better – Front Flange

Extra Mount

Satisfactory for maximum operating pressure and long strokes if properly applied. See separate Accessories Brochure for detailed mounting data and separate Engineering Brochure for long stroke information.

Best – Front Head Flange

Mount

Highly recommended. This is the best style of flange mounting. With this style, the cylinder can be mounted on the back face of the Head Flange if desired. This mounting style is used extensively on high tonnage presses and other heavy duty applications. To dimensionally interchange with the FF mount, see separate Accessories Brochure for Front Head Flange Spacer Bars.

We highly recommend that consideration be given to the use of a Style 6 rod end (see pages HH-21 and HH-22) and S.A.F.E. Coupling (see separate Accessories Brochure) to achieve good radial alignment.

Selection of piston rod diameter can be determined by consulting the separate Engineering Brochure.

REAR FLANGE MOUNT STYLE RF (MF2)*

REAR FLANGE MOUNT EXTRA SIZE STYLE RFX (MF6)*

REAR HEAD FLANGE MOUNT STYLE RHF (ME6)*

*ANSI/B93.1-1964 Mounting Style Designation.

IMPORTANT NOTICE

There is a construction variance in 11/8", 11/2", 2" bores, the 21/2" bore with a 13/8" and a 13/4" rod diameter, and the 31/4" bore with a 2" diameter rod. The round retainer shown above is not used on these sizes. A square retainer, the same square size as the head is employed. The retainer is cleared for the tie rods and held in place with the tie rod nuts.

In these sizes, the rod gland cannot be removed without loosening the tie rods. Dimensions are shown on the adjacent drawing.

On all other sizes, a round rod gland retainer is used. It is held in place by retainer screws–independent of the tie rods, hence, the rod gland CAN BE removed without loosening the tie rods.

1000 PSI Rated

HH-9

Page 11

Good – Rear Flange Mount

While this style of mount is a widely used one, its use should be restricted to pressures under 1000 psi, short strokes (under 36") and standard rod diameters. Note that the Rear Head Flange mount has the same mounting hole pattern.

Better – Rear Flange

Extra Mount

Best – Rear Head Flange

Mount

Highly recommended. This is the best style of flange mounting. With this style, the cylinder can be mounted on the back face of the flange if desired. This mounting style is used extensively on high tonnage presses and other heavy duty applications.

We highly recommend that consideration be given to the use of a Style 6 rod end (see pages HH-21 and HH-22) and S.A.F.E. Coupling (separate Accessories Brochure) to achieve good radial alignment.

Selection of piston rod diameter can be determined by consulting separate Engineering Brochure.

CAUTION

See separate Accessories Brochure for information concerning the application of Flange Mount Cylinders.

CAUTION

When specifying a Side Lug Mount with ports on the side (port positions 2, 4, 6 or 8), be sure that there will be enough clearance between the port fitting and the lug to insert a bolt or capscrew into the lug. In small bore sizes, it may even be necessary to employ a pipe nipple to easily pipe the port.

When specifying an End Lug Mount, carefully check the distance between the rod end and the lug to determine sufficient clearance for rod end attachment. It may be necessary to add extra plain rod extension to move the threaded rod end out beyond the lug. When using a rod eye or rod clevis, we recommend the extra plain rod extensions in Chart A below be specified.

Consult separate Accessories Brochure for information concerning the selection and application of lug mount cylinders. See separate Engineering Brochure for long stroke cylinder data. Selection of piston rod diameter can be determined from information in separate Engineering Brochure.

CAUTION

TF mount cylinders in bore sizes 5" through 8" with oversize piston rods and bore sizes 10", 12" and 14" with all piston rod diameters should not be used over 2,000 psi. If your application demands higher pressure, consult the factory.

Sheffer trunnion pins are an integral part of the head (TF Mount), the cap (TR Mount), or the ring on the intermediate trunnion mount (T). Even though machining the pins as an integral part is the strongest, and most fatigue-resistant method, some attention should be given to proper mounting of trunnion cylinders.

Pillow blocks of ample size and rigidity should be provided and should be mounted as close to the head or cap as possible. Bearing should be provided for the full length of the trunnion pin. Pins are designed for shear loads only, not bending loads. Lubrication should be provided to the pins.

All trunnion cylinders need provision on both ends for pivoting in one direction. Alignment in the other direction is essential in order to avoid excessive side loading. Where two-direction pivoting is necessary, contact our distributor for specific recommendations.

Selection of piston rod diameter can be determined by consulting separate Engineering Brochure.

See Engineering Brochure for information concerning the application of long stroke cylinders.

See separate Accessories Brochure for additional data on cylinder mounting.

only.

• Some bore and rod combinations are

not available in this mount.

• NA means not available.

• The 11/8" bore has only one tapped

hole in the head and in the cap.

Foot Bracket Mount – Notes

• Available 11/2" through 8" bore

sizes only.

• This style of mount is not recom-

mended for pressures in excess of 1000 psi or strokes over 36 inches. Consider the use of an End Lug mount or a Side Lug mount shown on Page HH-11.

Selection of Piston Rod Diameter can be determined by consulting separate Engineering Brochure.

See Engineering Brochure for long stroke cylinder data.

IMPORTANT NOTICE

There is a construction variance in the 11/8" bore, 11/2" bore, 2" bore, the 21/2" bore with a 13/8" and 13/4" rod diameter, and the 31/4" bore with a 2" rod diameter. The round gland retainers shown above are not used in these sizes. A square retainer, the same square size as the head, is employed on each end. The retainers are held in place by the tie rod nuts and therefore cannot be removed without loosening the tie rods.

See adjacent drawing for dimension details.

For dimensions on specific mounting styles, consult other pages in this brochure and separate Accessories Brochure. Dimensions shown on the above and adjacent drawings are for the BASIC CYLINDER ONLY.

Double rod extension cylinders are available in every mounting style except clevis.

IMPORTANT NOTICE

Reference adjacent drawing.

RX MOUNT - The round gland retainer shown above is not used on the 11/8" bore, 11/2" bore, or the 21/2" bore with a 13/4" rod diameter or the 31/4" bore with a 2" rod diameter. A square retainer, the same square size as the head, is employed in these sizes. The retainer is held in place with retainer screws and the gland can be removed without loosening the tie rods.

FX and BX MOUNTS - The square retainer is used on the 11/8" bore, 11/2" bore, 2" bore, the 21/2" bore

with a 1

/8"and 13/4" rod diameter, and the 31/4" bore with a 2" rod diameter. The retainer is held in place by the tie rod nuts, hence, the gland cannot be removed without loosening the tie rods.

NX MOUNT - The square retainer is used on the 11/8" bore, 11/2" bore, and the 2" bore with a 13/4" diameter rod and the 31/4" bore with a 2" rod diameter. The retainer is held in place with retainer screws that thread into the head and the rod gland can be removed without loosening the tie rods.

Double Rod End Cylinders

Double Rod End cylinders are specified for many reasons, some of which are as follows:

1. A simultaneous push and pull requirement.

2. Both rod ends are fixed and the

cylinder moves — such as on a

machine slide.

3. One rod does the work and the other serves to indicate position or to trip switches.

4. A double rod end cylinder has rod bearings at each end and therefore offers more resistance to deflection and side loading.

When the rod ends of a double rod end cylinder are not to be the same, such as a style 2 on one end and a style 4 on the other, be sure to so specify and to identify which end is which in relation to the mount. For example, on a Front Head Flange mount double rod end cylinder, specify style 2 rod end on flange end of cylinder and style 4 on opposite end.

Refer to Pages HH-21 and HH-22 for Rod End Information.

Cylinders of these very large bore sizes, are frequently custom made to suit specific customer requirements. Even though these sizes are not production run products (expect longer delivery time than experienced with smaller bore sizes), basic design criteria and

dimensions have been established by Sheffer for the three most popular mounting styles.

We will be happy to quote you on variations of these mounts or on mounting styles not shown. To reduce

costs and delivery time, whenever possible design to the standard mounts and dimensions shown.
