Parker's New, ExclusiveStepped floating cushionscombine the best features ofknown cushion technology.Deceleration devices or built-in “cushions” are optional and can besupplied at head end, cap end, or both ends without change inenvelope or mounting dimensions. Parker cylinder cushions are astepped design and combine the best features of known cushiontechnology.Standard straight or tapered cushions have been used in industrialcylinders over a very broad range of applications. Parker researchhas found that both designs have their limitations.As a result, Parker has taken a new approach in cushioning ofindustrial hydraulic cylinders and for specific load and velocityconditions have been able to obtain deceleration curves that comevery close to the ideal. The success lies in a stepped sleeve orspear concept where the steps are calculated to approximatetheoretical orifice areas curves.In the cushion performance chart, pressure traces show theresults of typical orifice flow conditions. Tests of a three-stepsleeve or spear show three pressure pulses coinciding with thesteps. The deceleration cushion plunger curves shape comes veryclose to being theoretical, with the exception of the last 1/2 inch of

Piston Rod – Medium carbon steel, induction case-hardened to 54 Rc,hard chrome-plated and polished to 10 RMS finish. Piston rods aremade from 90,000 to 100,000 psi minimum yield material in 5/8"through 4" diameters. Larger diameters vary between 57,000 and90,000 psi minimum material, depending on rod diameter. The pistonthread equals the catalog style #4 rod end thread for each roddiameter to assure proper piston-to-rod thread strength. Two wrenchflats are provided for rod end attachment.
Ports – S.A.E. “O” ring portsare standard.
Steel Cap – Bored and groovedto provide concentricity for mat-ing parts.
Optional PortsPorts – N.P.T.F. ports are optionalat no extra charge. OversizeN.P.T.F. and S.A.E. ports areavailable at extra charge.Seals – Buna-N (Nitrile) seals arestandard.Viton Seals – Optional atextra charge.
Step Cut IronPiston Rings arestandard.
One-Piece Fine Grained Cast Iron Piston –The wide piston surface contacting cylinderbore reduces bearing loads, and a long threadengagement with rod provides greater shockabsorption. Anaerobic adhesive is used topermanently lock and seal the piston tothe rod.
Align-A-Groove –(Patent #3043639) – A 3/16" widesurface machined at each end ofthe cylinder body. Makes precisemounting quick and easy.

head even when wide open. It may be identified by the factthat it is socket-keyed. It is located on side number 2, in allmounting styles except D, DB, DD, JJ, HH and E. In thesestyles it is located on side number 3.
c. On 5" bore and larger cylinders (except for 21/2" bore withcode 2 rod), a springless check valve is provided that is alsoflush with the side of the head and is mounted adjacent tothe needle valve except on mounting style C, where it ismounted opposite the needle valve. It may be identified bythe fact that it is slotted.
d. On 11/2" - 4" bore cylinders a slotted sleeve design is used inplace of the check valve.
e. 11/2" - 2" bore cylinders use a cartridge style needle valve(see Figure A).
(2)When a cushion is specified at the cap end:a. A cushion stepped spear is provided on the piston rod.
The exclusive“Jewel” glandgives you longercylinder life, betterperformance andlower costs.An extra-long inboard bearing surfaceinsures lubrication from within thecylinder. Outboard of the bearing surface are two leakproof seals –The TS-2000 and Wiperseal. The serrated TS-2000 (primary seal)is completely self-compensating and self-relieving. It adjusts tomechanical deflections or any pressure variation from near-zero torated operating pressure. The result is positive, no-leak sealing –regardless of conditions.The Wiperseal does double duty. On the advance stroke, it acts asa secondary pressure seal. On the return, it wipes away any dirton the rod. This means less wear on bearing surfaces and internalparts. Longer life for working parts. And, less loss of fluid. Plus, youcan replace a “Jewel” gland without removing the tie rods or theretainer. Just a few twists with a spanner wrench does the job.

To determine dimensions for a double rodcylinder, first refer to the desired single rodmounting style cylinder shown onpreceding pages of this catalog. (See tableat left.) After selecting necessarydimensions from that drawing, return tothis page supplement the single roddimensions with those shown on drawingat right and dimension table below. Notethat double rod cylinders have a head(Dim. G) at both ends and that dimensionLD replaces LB and ZL replaces ZB, etc.The double rod dimensions differ from, or
are in addition to those for single rodcylinders shown on preceding pages andprovide the information needed tocompletely dimension a double rodcylinder.On a double rod cylinder where the tworod ends are different, be sure to clearlystate which rod end is to be assembled atwhich end. Port position 1 is standard. Ifother than standard, specify pos. 2, 3 or 4when viewed from one end only. See portposition information in Section C.

Series 2HHeavy Duty Hydraulic CylindersSeries “2H” Model Numbers – How to Develop Them – How to “Decode” Them
Model Numbers
Parker Series 2H cylinders can be completely and accurately describedby a model number consisting of coded symbols. For single rod cylin-ders a maximum of 17 places for digits and letters are used in a pre-scribed sequence to produce a model number. Only nine places areneeded to completely describe a standard noncushioned Series 2H
cylinder. To develop a model number, select only those symbols thatrepresent the cylinder required, and place them in the sequenceindicated below.Note: Page numbers with a letter prefix, ie: C77, are located insection C of this catalog.

Parker TS-2000 seal designed toeliminate cylinder rod seal leakage.
WorldclassQuality Productsand Service
“Jewel” gland with wiperseal andTS-2000 cylinder rod seal.
Parker Series 2H Heavy Duty andSeries 3L Medium Duty HydraulicCylinders with the TS-2000 sealoffers positive protection againstcylinder rod leakage under themost demanding applications.
The TS-2000 seal is the product ofcountless hours of research,development and extensive fieldtesting and is only available on ParkerCylinders.
Based on the popular ParkerSerrated Lipseal rod design, theTS-2000 incorporates the pressure-compensated, uni-directionalcharacteristics of a U-cup with themultiple edge sealing effectiveness ofcompression-type stacked-packings.
The goal for the Parker team was todesign a rod seal suitable for all typesof applications, regardless of pressureprofile. It had to be composed of a
material that would not reactchemically with hydraulic fluids. And ithad to produce better and morereliable “dry rod” performance than thestandard serrated lip-seal design in abroad range of applications.
The result is the TS-2000 seal,designed especially to eliminate rodseal leakage in the most demandingapplications. It features a specialpolyurethane material that will not reactchemically with petroleum-basedhydraulic •uid, is extremely resistant toabrasion and extrusion, and providesexceptional service life. It hasmore sealing edges thanother seals on themarket, which
in turn produces “dry rod”performance. The seal geometry wasrefined for maximum stability in thegroove and has excellentperformance characteristicsthroughout a broad range ofpressures and piston rod velocities.
The Parker design team wassuccessful!
TS-2000 rod seal has not failed inany of the test applications in the labor on the job, no matter how tough ordemanding.
For more information on theTS-2000 call or write your localParker distributor or Parker HannifinCorporation, Cylinder Division, 500S. Wolf Road, Des Plaines, IL 60016,847-298-2400.
