The inside story on why series 2H is your best choice in heavy duty hydraulic cylinders Steel Head – Bored and grooved to provide concentricity for mating parts. Ports – S.A.E. “O” ring ports are standard. End Seals – Pressure-actuated cylinder body-to-head and cap “O” rings. Primary Seal – New TS-2000 Rod Seal is a proven leakproof design – completely selfcompensating and self-relieving to withstand variations and conform to mechanical deflection that may occur. “Jewel” Rod Gland Assembly – Externally removable without cylinder disassembly. Long bearing surface is inboard of the seals, assuring positive lubrication from within the cylinder. An “O” ring is used as a seal between gland and head, and also serves as a prevailing torquetype lock. Secondary Seal – Double-Service Wiperseal (Hannifin Patent #2907596) – wipes clean any oil film adhering to the rod on the extend stroke and cleans the rod on the return stroke. Stepped Cushions Sleeve Design Spear Design Parker's New, Exclusive Stepped floating cushions combine the best features of known cushion technology. Deceleration devices or built-in “cushions” are optional and can be supplied at head end, cap end, or both ends without change in envelope or mounting dimensions. Parker cylinder cushions are a stepped design and combine the best features of known cushion technology. Standard straight or tapered cushions have been used in industrial cylinders over a very broad range of applications. Parker research has found that both designs have their limitations. As a result, Parker has taken a new approach in cushioning of industrial hydraulic cylinders and for specific load and velocity conditions have been able to obtain deceleration curves that come very close to the ideal. The success lies in a stepped sleeve or spear concept where the steps are calculated to approximate theoretical orifice areas curves. In the cushion performance chart, pressure traces show the results of typical orifice flow conditions. Tests of a three-step sleeve or spear show three pressure pulses coinciding with the steps. The deceleration cushion plunger curves shape comes very close to being theoretical, with the exception of the last 1/2 inch of High Strength Tie Rods – Made from 100,000 psi minimum yield steel with rolled threads for added strength. The Cylinder Body – Heavy-wall steel tubing, honed to a micro finish bore. Adjustable Floating Stepped Cushions – For maximum performance – economical and flexible for even the most demanding applications – provides superior performance in reducing shock. Cushions are optional and can be supplied at head end, cap end, or both ends without change in envelope or mounting dimensions. travel. This is a constant shape in order to have some flexibility in application. The stepped cushion design shows reduced pressure peaks for most load and speed conditions, with comparable reduction of objectionable stopping forces being transmitted to the load and the support structure. All Parker Hannifin CUSHION PERFORMANCE cushions are STRAIGHT CUSHION TYPICAL adjustable. The Series 2H cylinder design incorporates the longest cushion IDEAL CUSHION sleeve and cushion spear that can be TYPICAL STEPPED CUSHION provided in the standard envelope without decreasing the rod bearing and piston bearing strengths. CUSHION PRESSURE Piston Rod Stud – Furnished on 2" diameter rods and smaller when standard style #4 rod end threads are required or on 13/8" diameter rods and smaller when style #8 threads are required. Also available in 2 times the catalog “A” dimension length. Studs have rolled threads and are made from high strength steel. Anaerobic adhesive is used to permanently lock the stud to the piston rod. (1) When a cushion is specified at the head CUSHION POSITION end: a. A self-centering stepped sleeve is furnished on the piston rod assembly. b. A needle valve is provided that is flush with the side of the For additional information – call your local Parker Cylinder Distributor. 42
Piston Rod – Medium carbon steel, induction case-hardened to 54 Rc, hard chrome-plated and polished to 10 RMS finish. Piston rods are made from 90,000 to 100,000 psi minimum yield material in 5/8" through 4" diameters. Larger diameters vary between 57,000 and 90,000 psi minimum material, depending on rod diameter. The piston thread equals the catalog style #4 rod end thread for each rod diameter to assure proper piston-to-rod thread strength. Two wrench flats are provided for rod end attachment. Ports – S.A.E. “O” ring ports are standard. Steel Cap – Bored and grooved to provide concentricity for mating parts. Optional Ports Ports – N.P.T.F. ports are optional at no extra charge. Oversize N.P.T.F. and S.A.E. ports are available at extra charge. Seals – Buna-N (Nitrile) seals are standard. Viton Seals – Optional at extra charge. The exclusive “Jewel” gland gives you longer cylinder life, better performance and lower costs. An extra-long inboard bearing surface insures lubrication from within the cylinder. 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 to mechanical deflections or any pressure variation from near-zero to rated operating pressure. The result is positive, no-leak sealing – regardless of conditions. The Wiperseal does double duty. On the advance stroke, it acts as a secondary pressure seal. On the return, it wipes away any dirt on the rod. This means less wear on bearing surfaces 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 a few twists with a spanner wrench does the job. Optional Pistons Lipseal Piston – Optional at no extra charge. Zero leakage under static conditions for hydraulic pressures up to 3000 psi. Seals are self-compensating to conform to variations in pressure, mechanical deflection, and wear. Back-up washers prevent extrusion. Alloy Steel Tie Rod Nuts Align-A-Groove – (Patent #3043639) – A 3/16" wide surface machined at each end of the cylinder body. Makes precise mounting quick and easy. Step Cut Iron Piston Rings are standard. One-Piece Fine Grained Cast Iron Piston – The wide piston surface contacting cylinder bore reduces bearing loads, and a long thread engagement with rod provides greater shock absorption. Anaerobic adhesive is used to permanently lock and seal the piston to the rod. head even when wide open. It may be identified by the fact that it is socket-keyed. It is located on side number 2, in all mounting styles except D, DB, DD, JJ, HH and E. In these styles it is located on side number 3. c. On 5" bore and larger cylinders (except for 21/2" bore with code 2 rod), a springless check valve is provided that is also flush with the side of the head and is mounted adjacent to the needle valve except on mounting style C, where it is mounted opposite the needle valve. It may be identified by the fact that it is slotted. d. On 11/2" - 4" bore cylinders a slotted sleeve design is used in place of the check valve. 1 e. 1 /2" - 2" bore cylinders use a cartridge style needle valve (see Figure A). Nut Retained Piston – Optional at extra charge. 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 is flush with the side of the cap when wide open. It is located on side number 2 in all mounting styles except D, DB, DD, JJ, HH and E. In these styles it is located on side number 3. Cushion Length Cyl. Rod Bore Dia. In. In. 5/8 11/2 1 21/2 31/4 4 (2) When a cushion is specified at the cap end: a. A cushion stepped spear is provided on the piston rod. Hi Load Piston – Optional at extra charge. Includes wear rings and bronze-filled PTFE seals. Two wear rings serve as bearings which deform radially under side-loading, enabling the load to be spread over a larger area and reduce unit loading. Bronze-filled PTFE seals are designed for extrusion-free, leak-proof service and longer cylinder life than the lipseal type piston.
