The inside story on whySeries 2A is your best choice inheavy duty pneumatic cylinders
Primary Seal – Unique Serrated Lipseal® is aproven leakproof design, (Parker Patent #2997318)– completely self-compensating and self-relievingto withstand variations and conform to mechanicaldeflection that may occur.
Adjustable floating cushionsCushions are optional, and can be supplied at head end,cap end, or both ends without change in envelope ormounting dimensions. All Parker cushions are adjustable.The Series 2A cylinder design incorporates the longestcushion sleeve and cushion spear that can be provided inthe standard envelope without decreasing the rod bearingand piston bearing lengths.
(1) When a cushion is specified at the head end:a. A self-centering sleeve is furnished on the piston
rod assembly.b. A needle valve is provided that is flush with the
side of the head when wide open. It may beidentified by the fact that it is socket-keyed. It islocated on side number 2, in all mounting stylesexcept D, DB, DD, and E. In these styles it islocated on side number 3.
c. A springless check valve is provided that is alsoflush with the side of the head and is mounted
adjacent to the needle valve except on certain boresof mounting style C where it is mounted opposite theneedle valve. It may be identified by the fact that it isslotted.
d. The check and needle valves are interchangeablein the head.
(2) When a cushion is specified at the cap end:a. A cushion spear is provided on the piston
rod assembly.b. A “float check” self-centering bushing is provided
which incorporates a large flow check valve for fast“out-stroke” action.
c. A socket-keyed needle valve is provided that isflush with the side of the cap when wide open. It islocated on side number 2 in all mounting stylesexcept D, DB, DD, and E. In these styles it islocated on side number 3.
Piston Rod Stud –Furnished on 2" diameterrods and smaller whenstandard style #4 rodend threads are requiredor on 13/8" diameter rodsand smaller when style#8 threads are required.Also available in 2 timesthe catalog “A” dimen-sion length. Studs haverolled threads and aremade from high strengthsteel. Anaerobicadhesive is used topermanently lock thestud to the piston rod.
Steel Head – Bored and groovedto provide concentricity for matingparts.
Ports – NPTF portsare standard.
End Seals – Pressure-actuatedcylinder body-to-head and cap“O” rings.
“Jewel” Rod GlandAssembly –Externally removablewithout cylinderdisassembly. Longbearing surface isinboard of the seals,assuring positivelubrication from withinthe cylinder. An “O”ring is used as a sealbetween gland andhead, and also servesas a prevailingtorque-type lock.
High Strength TieRods – Made from100,000 psi minimumyield steel with rolledthreads for addedstrength.
The Cylinder Body– Hard chrome-plated bore, steeltubing honed to a 15micro inch finish on11/2" through 14" boresizes. 1" bore size isaluminum with hard-coated bore.
Adjustable Floating Cushions – Cushionsare optional and can be supplied at head end,cap end, or both ends without change inenvelope or mounting dimensions.
Secondary Seal –Double-Service Wiperseal® (ParkerPatent #2907596) – acts as asecondary pressure seal on theextend stroke and cleans the rod onthe return stroke.

Alloy Steel Tie Rod Nuts
Ports – NPTF portsare standard.
Steel Cap – Bored and groovedto provide concentricity formating parts.
Align-A-Groove –(Patent #3043639) – A 3/16" widesurface machined at each end ofthe cylinder body. Makes precisemounting quick and easy.
One-Piece Nodular IronPiston – The wide pistonsurface contacting cylinder borereduces bearing loads.Anaerobic adhesive is used topermanently lock and seal thepiston to the rod.
Piston Lipseal – Fully dynamicand self-compensating forvariations in pressure, mechani-cal deflections and wear.
The exclusive“Jewel” glandgives you longercylinder life, betterperformance andlower costs.An extra-long inboard bearing surface insures lubricationfrom within the cylinder. Outboard of the bearing surfaceare two leakproof seals – The Lipseal and Wiperseal. Theserrated Lipseal (primary seal) is completely self-compen-sating and self-relieving. It adjusts to mechanical deflec-tions or any pressure variation from near-zero to ratedoperating pressure. The result is positive, no-leak sealing –regardless of conditions.The Wiperseal does double duty. On the advance stroke, itacts as a secondary pressure seal. On the return, it wipesaway any dirt on the rod. This means less wear on bearingsurfaces and internal parts. Longer life for working parts.And, less loss of fluid. Plus, you can replace a “Jewel”gland without removing the tie rods or the retainer. Just afew twists with a spanner wrench does the job.
Prelubricated Wearing SurfacesParker Series 2A Air Cylinders are factory prelubricated.Lube-A-Cyl applied to seals, piston, cylinder bore, pistonrod and gland surfaces provides lubrication for normaloperation. Lube-A-Cyl has been field and laboratorytested, and is recommended by Parker for air cylinderswhere lubricant should remain in the cylinder and not beexpelled into the atmosphere.
Piston with Retainer Nut –Optional at extra charge.

All dimensions are in inches and apply to Code 1 rod sizes only. For alternate rod sizes,determine all envelope dimensions (within LD dim.) as described above and then useappropriate rod end dimensions for proper rod size from single rod cylinder.
To determine dimensions for a double rodcylinder, first refer to the desired single rodmounting style cylinder shown on precedingpages of this catalog. (See table at left.) Afterselecting necessary dimensions from thatdrawing, return to this page supplement thesingle rod dimensions with those shown ondrawings at right and dimension table below.Note that double rod cylinders have a head(Dim. G) at both ends and that dimension LDreplace LB and ZL replaces ZB, etc. Thedouble rod dimensions differ from, or are in
addition to those for single rod cylindersshown on preceding pages and provide theinformation needed to completely dimensiona double rod cylinder.On a double rod cylinder where the two rodends are different, be sure to clearly statewhich rod end is to be assembled at whichend. Port position 1 is standard. If other thanstandard, specify pos. 2, 3 or 4 when viewedfrom rod end #1 only. See port positioninformation in Section C.

How to Order
Series 2AHeavy Duty Air Cylinders
How to Order Series “2A” CylindersWhen ordering Series 2A cylinders, please review the following:Note: Duplicate cylinders can be ordered by giving the SERIALNUMBER from the nameplate of the original cylinder. Factory recordssupply a quick positive identification.
Piston Rods: Specify rod code number based on diameter. Givethread style number for a standard thread or specify dimensions. See“Style 3 Rod End” below.
Cushions: If cushions are required specify according to the modelnumber on the next page. If the cylinder is to have a double rod andonly one cushion is required, be sure to specify clearly which end ofthe cylnder is to be cushioned.
Service PolicyOn cylinders returned to the factory for repairs, it is standard policy forthe Cylinder Division to make such part replacements as will put thecylinder in as good as new condition. Should the condition of the returnedcylinder be such that expenses for repair would exceed the costs of anew one, you will be notified.Address all correspondence and make shipments to, ServiceDepartment at your nearest regional plant listed in the pages of thiscatalog.
Certified DimensionsParker Cylinder Division guarantees that all cylinders ordered from thiscatalog will be built to dimensions shown. All dimensions are certified tobe correct, and thus it is not necessary to request certified drawings.
Class 1 SealsClass 1 seals are the seals provided as standard in a cylinderassembly unless otherwise specified. For further information on fluidcompatibility or operating limitations of all components, see section C.For the 2A series cylinders the following make-up Class 1 Seals:Primary Piston Rod Seal – Nitrile with PTFE back-up washers
Piston Rod Wiper – NitrilePiston Seals – Nitrile with polymyte back-up washersO-Rings – Nitrile
Style 3 Rod EndA style 3 rod end indicates a special rod end configuration. All specialpiston rod dimensions must have all three: KK; A; W/WF or LA/LAFspecified with the rod fully retracted. A sketch or drawing should besubmitted for rod ends requiring special machining such as snap ringgrooves, keyways, tapers, multiple diameters, etc. It is good designpractice to have this machining done on a diameter at least 0.065inches smaller than the piston rod diameter. This allows the piston rodto have a chamfer preventing rod seal damage during assembly or
maintenance. Standard style 55 rod ends with a longer than standardWG dimension should call out a style 3 rod end and the note: sameas 55 except WG=____. A drawing should be submitted for special55 rod ends that have specific tolerances or special radii. Special rodends that have smaller than standard male threads, larger thanstandard female threads, or style 55 rod ends with smaller thanstandard AF or AE dimensions are to be reviewed by Engineering forproper strength at operating pressure.
Combination MountingsSingle Rod End The first mounting is the one called out on the headend of the cylinder. The second or subsequent mountings are calledout as they appear in the assembly moving away from the rod end.Exception: When tie rod mountings are part of a combination, themodel number should contain an “S” (Special) in the model code anda note in the body of the order clarifying the mounting arrangement.The ”P” is used to define a thrust key and is not considered to be amounting. However, it is located at the primary end.
Example: 4.00 CCBB2ALTS14AC x 10.000Combination “C” mounting head only. “BB” mounting cap endThis cylinder is also cushioned at both ends.
Double Rod End In general, the model number is read left to rightcorresponding to the cylinder as viewed from left to right with the
primary end at rod end #1. See Double Rod Models information pagein this section. For this option the piston rod number, piston rod end,and piston rod threads are to be specified for both ends. The simplestare for symmetric cylinders such as: TD, C, E, F, G, and CB mounts.All other mounting styless, the description of the first rod end will be atthe mounting end. In the case of multiple mounts, the description ofthe first rod end will be at the primary mounting end. For “DD”mounts, the description of the first rod end will be the same locationas the “XI” dimension.Example: 4.00 KDD2ALT24A/18A x 10.000 XI=8
This is a center trunnion mounting cylinder with the XI dimensionmeasured from the code 2 rod side of the cylinder which has the style4 thread. The opposite end code 1 rod with the style 8 thread.
Special Modifications: Additional information is required on ordersfor cylinders with special modifications. This is best handled withdescriptive notes. For further information, consult factory.
Fluid Medium: Series 2A hydraulic cylinders are equipped with sealsfor use with lubricated air.
