Miller. . . HV2 Series your best choice in heavy duty hydraulic cylindersPrimary Seal New Tuffseal Rod Seal is a proven leakproof design completely self-compensating and self-relieving to withstand variations and conform to mechanical deflection that may occur.

Steel Head Bored and grooved to provide concentricity for mating parts.

End Seal Pressure-actuated cylinder tube-to-head and cap O rings.

Secondary Seal Rod Wiper wipes clean any oil film adhering to the rod on the extend stroke and cleans the rod on the return stroke.

Piston Rod Stud Furnished on 2" diameter rods and smaller when standard style #2 rod end threads are required or on 13/8" diameter rods and smaller when style #5 threads are required. Studs have rolled threads and are made from high strength steel. Anaerobic adhesive is used to permanently lock the stud to the piston rod.

Rod Bushing Assembly Nodular iron bushing is externally removable without cylinder disassembly. An O ring is used as a seal between bushing and head.

High Strength Tie Rods Made from 100,000 PSI minimum yield steel with rolled threads for added strength.

The Cylinder Tube Heavywall 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.

Lipseal Piston 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 washer prevents extrusion.

Millers 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. Miller 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, Miller research has found that both designs have their limitations. As a result, Miller 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 plunger 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 plunger show three pressure pulses coinciding with the steps. The deceleration curve shape comes very close to being theoretical, with the exception of the last 1/2 inch of travel.

CUSHION PRESSURE

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 Miller HV2 cushions are adjustable. The HV2 Series cylinder design incorporates the longest cushion plungers that can be provided in the standard envelope without decreasing the rod bearing and piston bearing lengths.

Steel Cap Bored and grooved to provide concentricity for mating parts. Bushing Assembly with Tuffseal Rod Seal Bushing Assembly externally removable without cylinder disassembly. An O-ring is used as a seal between the bushing and head. The serrated Tuffseal (primary seal) is completely self-compensating and self-relieving. The result is positive, no-leak sealing regardless of conditions. The Wiperseal wipes away any dirt on the rod. This means less wear on bearing surfaces and internal parts.

OPTIONAL PORTSPorts 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.

OPTIONAL PISTONSStep cut iron piston rings are optional.

Alloy Steel Tie Rod Nuts.

Piston with Retainer Nut Optional at no extra charge. Align-A-Groove (Patent #3043639) A 3/16" wide surface machined at each end of the cylinder body. Makes precise mounting quick and easy.

FILLED PTFE BEARINGS

BRONZE FILLED PTFE RINGS

One-Piece Nodular Iron Piston The wide piston surface contacting cylinder bore reduces bearing loads. Anaerobic adhesive is used to permanently lock and seal the piston to the rod.SYNTHETIC RUBBER EXPANDER RINGS

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. Not available with retainer nut.

(1) When a cushion is specified at the head end: a. A self-centering stepped plunger is furnished on the piston rod assembly. b. A needle valve is provided that is flush with the side of the 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 models except 67, 68, 81, 82 and 89. In these models it is located on side number 3. c. On 6" bore and larger cylinders, 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 model 72, where it is mounted opposite the needle valve. It may be identified by the fact that it is slotted. d. On 11/2" - 5" bore cylinders a slotted sleeve design is used in place of the check valve. e. 11/2" - 21/2" bore cylinders use cartridge style needle valve (see Figure A).

(2) When a cushion is specified at the cap end: a. A stepped plunger is provided on the piston rod. 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 models except 67, 68, 81, 82 and 89. In these models it is located on side number 3.

Miller HV2 Series Heavy-Duty Hydraulic CylindersHow to Use Double Rod Cylinder Dimensioned DrawingsTo determine dimensions for a double rod cylinder, first refer to the desired single rod mounting style cylinder shown on preceding pages of this catalog. See table at right. After selecting necessary dimensions from that drawing return to this page, supplement the single rod dimensions with those shown on drawing at right and dimension table below. Note that double rod cylinders have a head (Dim. G) at both ends and that dimension LD replaces LB. The double rod dimensions differ from, or are in addition to, those for single rod cylinders shown on preceding pages and provide the information needed to completely dimension a double rod cylinder.

On a double rod cylinder where the two rod ends are different, be sure to clearly state which rod end is to be assembled at which end. Port position 1 is standard. If other than standard, specify pos. 2, 3 or 4 when viewed from one end only.

All dimensions are in inches and apply to smallest rod sizes only. For alternate rod sizes, determine all envelope dimensions (within LD dim.) as described above and then use appropriate rod end dimensions for proper rod size from single rod cylinder.
