Design Features and Benefits 5 6 8 Piston Gland seal life is imised by manufacturing piston rods from precision ground, high tensile carbon alloy steel, hard chrome plated and polished to 0.µm. Piston rods are induction case hardened to Rockwell C54 minimum before chrome plating, resulting in a dent-resistant surface. 0 Parker's Detachable Gland Continuous lubrication, and therefore longer gland life, are provided by the long bearing surface inboard of the lipseal. The gland, complete with rod seals, can easily be removed without dismantling the cylinder, so servicing is quicker and therefore more economical. Seals Efficient sealing under all operating conditions is achieved by using a serrated lipseal with a series of sealing edges which increase the sealing effect as pressure increases. On the return stroke these serrations act as a check valve, allowing the oil adhering to the rod to pass back into the cylinder. 4 7 & 8 7 9 The double lip wiperseal acts as a secondary seal, trapping excess lubricating film in the chamber between the wiper and lip seals. Its outer lip prevents the ingress of dirt into the cylinder, extending the life of gland and seals. Standard lipseals are manufactured from an enhanced polyurethane, giving effi cient retention of pressurized fluid and a service life of up to five times that of traditional seal materials. Standard rod seals are suitable for speeds of up to 0.5m/s special seals are available for higher speed applications. 4 Cylinder Body Strict quality control standards and precision manufacture ensure that all tubes meet strict standards of straightness, roundness and surface finish. The steel tubing is surface finished to minimise internal friction and prolong seal life. 5 Cylinder Body Seals To make sure that the cylinder body remains leaktight, even under pressure shock conditions, Parker fits pressure-energised body seals. 6 One-Piece Piston Side loading is resisted by the wear rings on the piston. A long thread engagement secures the piston to the piston rod and, as an added safety feature, pistons are secured by both a threadlocking compound and a locking pin. Three standard seal combinations are available to suit different applications see 'Piston Seals' opposite. 7 Cushioning Cushioning reduces noise and shock loading, resulting in faster cycle times and higher productivity. Progressive deceleration is available by selecting profiled cushions at the head and cap see page 0 for details. The head end cushion is self-centring, while the polished cap end spear is an integral part of the piston rod. 4
Design Features and Benefits 8 Floating Cushion Bushes & Sleeves Closer tolerances and therefore more effective cushioning are permitted by the use of a floating cushion sleeve at the head end of the cylinder, and a floating cushion bush at the cap end. A specially designed cushion sleeve on bore sizes up to 00mm operates as a check valve. On larger bore sizes a conventional ball check valve is used. The use of a check valve in the head and lifting of the bronze cushion bush in the cap, provides minimal fluid restriction to the start of the return stroke. This allows full pressure to be applied over the whole area of the piston, to provide full power and fast cycle times. 9 Cushion Adjustment Needle valves are provided at both ends of the cylinder for precise cushion adjustment, and retained within the head and cap so that they cannot be inadvertently removed. The cartridge type needle valve illustrated below is fitted to cylinders of up to mm bore for location, see page 4. 0 Tie Construction Tie rod construction, with tie rods torque-loaded on assembly, imposes a compressive force on the cylinder tube which counters the tensile forces generated by system pressure. The result a fatigue-free cylinder with long service life and exceptionally compact dimensions. Special Designs Parker's design and engineering staff are available to produce special designs to meet customer's specific requirements. Alternative sealing arrangements, special mounting styles, different bores and rod sizes are just a few of the custom features which can be supplied. Piston Seals A variety of piston seal options are available, to suit different applications. Standard Pistons are suitable for holding a load in position, as the piston seals are leak-tight under normal operating conditions. Wear rings prevent metal-to-metal contact. Standard piston seals are suitable for piston speeds up to m/s. LoadMaster Pistons employ extra heavy duty wear rings to resist side loading and are recommended for long stroke cylinders, especially when pivot mounted. Servo Cylinders Servo cylinders permit fine control of acceleration, velocity and position in applications where very low friction and an absence of stick-slip are required. They may be used in conjunction with integral or external transducers. Low Friction Pistons employ a PTFE seal and PTFE wear rings, and may be used for piston speeds up to m/s. They are not suitable for supporting loads in a fixed position. Low Friction Gland Seals comprise two low friction PTFE stepped seals and a conventional double lip wiper seal see page. 5
Optional Features Air Bleeds The option of bleed screws is available at either or both ends of the cylinder, at any position except in the port face. On cylinders of mm bore and above, where it is essential to have the air bleed in the port face, bosses can be welded to the cylinder tube. To ensure operator safety, they are recessed into the head and cap and retained so that they cannot be inadvertently removed. Gland Drains The accumulation of fluid between the gland seals of long stroke cylinders, cylinders with constant back pressure or where the ratio of the extend speed to the retract speed is greater than to, can be relieved by specifying an optional gland drain. A transparent tube fitted between the port and the reservoir allows fluid loss from concealed or inaccessible cylinders to be monitored, giving an early indication of the need for gland servicing. A gland drain port can be provided in the retainer on all mounting styles except JJ to mm bores, and style D 00 to 00mm bores, where it is mounted in the head. Where the gland drain is provided in the retainer, the thickness of the retainer is increased by 6mm on and mm bore cylinders with no. rod, and by 4mm on mm bore cylinders with no. rod. Note that, on style JJ cylinders, drain ports cannot normally be positioned in the same face as ports or cushion valves please consult the factory. - -00 Port Thread Style JJ All Others /8 BSPP /8 NPTF /8 BSPP /8 BSPP Stroke Limiters Where absolute precision in stroke length is required, a screwed adjustable stop can be supplied. Several types are available please contact the factory, specifying details of the application and the adjustment required. Locking Devices These units provide positive locking of the piston rod. Of fail-safe design, they require hydraulic pressure to release and loss of pressure causes the clamp to operate. Please contact the factory for further information. Single-Acting Cylinders Standard HMI and HMD series cylinders are of the double-acting type. They are suitable for use as single-acting cylinders, where the load or other external force is used to return the piston after the pressure stroke. Spring-Returned, Single-Acting Cylinders Single-acting cylinders can also be supplied with an internal spring to return the piston after the pressure stroke. Please supply details of load conditions and friction factors, and advise whether the spring is required to advance or return the piston rod. On spring-returned cylinders, it is recommended that tie rod extensions be specified to allow the spring to be 'backed off' until compression is relieved. Please contact the factory when ordering spring-returned cylinders. Multiple Stroke Positioning To obtain linear force in one plane with controlled stopping at intermediate points, several designs are available. Three stopped positions can be achieved by mounting two standard single rod Style HH cylinders back-to-back, or by using throughtie rods. By extending or retracting the stroke of each cylinder independently, it is possible to achieve three positions at the piston ends. An alternative technique is to use a tandem cylinder with an independent piston rod in the cap section. Please consult the factory for further details. End Bellows Unprotected piston rod surfaces which are exposed to contaminants should be protected by rod end bellows. Longer rod extensions are required to accommodate the collapsed length of the bellows. Please consult the factory for further information. Metallic Wipers Metallic rod wipers replace the standard wiper seal, and are recommended where dust or splashings might damage the wiper seal material. Metallic rod wipers do not affect the overall dimensions of cylinders of mm bore and above where the overall dimensions of smaller bore cylinders are critical, please consult the factory. Position Sensors These can be fitted to give reliable end of stroke or mid-stroke signals. Please contact the factory for further details. Position Feedback Linear position transducers of various types are available for HMI and HMD series cylinders. Please contact the factory for further details. All dimensions are in millimetres unless otherwise stated. 6

Double Cylinders Double Cylinder Available with Styles TB, TD, JJ, C, D, DD (Style C Illustrated) Double Cylinders Mounting Styles and Codes Double rod cylinders are denoted by a 'K' in the cylinder model code, shown on page 9. DIN Cylinder Range HMD double rod cylinders are only available with mounting styles JJ, C and DD and rod numbers and. These cylinders do not conform to DIN 4 554. Dimensions To obtain dimensional information for double rod cylinders, first select the desired mounting style by referring to the corresponding single rod models shown on pages 8 to. These should be supplemented with dimensions from the table opposite to provide a full set of dimensions. Strength Double rod cylinders employ two separate piston rods, with one screwed into the end of the other within the piston assembly. As a result, one piston rod is stronger than the other. The stronger rod can be identified by the letter 'K' stamped on its end. Different imum pressure ratings apply to the stronger and weaker rods of a double rod cylinder see Pressure Limitations, page.

Mounting Information Front Flange Mountings Style JJ front flange-mounted cylinders, see page 9, incorporate a location diameter for accurate alignment on the mounting surface. The gland retainer is integral with the head on, and mm bore cylinders, while on mm bores and above, the circular retainer is bolted to the head. Extended Tie s Cylinders may be ordered with extended tie rods in addition to another mounting style. The extended tie rods may then be used for mounting other systems or machine components. An additional set of mounting nuts is supplied. Foot Mountings and Thrust Keys The turning moment which results from the application of force by a foot mounted cylinder must be resisted by secure mounting and effective guidance of the load. An optional thrust key is recommended to provide positive cylinder location. Thrust key mountings eliminate the need for fitted bolts or external keys on style C side mounted cylinders.

Theoretical Push and Pull Forces Calculation of Cylinder Diameter Compression or 'Push' Applications If the piston rod is in compression, use the 'Push Force' table.. Identify the operating pressure closest to that required.. In the same column, identify the force required to move the load (always rounding up).. In the same row, look along to the cylinder bore required. If the cylinder envelope dimensions are too large, increase the operating pressure, if possible, and repeat the exercise.

Piston Sizes & Stop Tubes Piston Size Selection To select a piston rod for compression (push) applications:. Determine the type of mounting style and rod end connection to be used. From the Stroke Factor table below, identify which factor corresponds to the application.. Using this stroke factor, determine the 'basic length' from the equation: Basic Length = Net Stroke x Stroke Factor (The Piston Selection Chart, opposite, is prepared for the standard rod extension beyond the face of the gland retainer. For rod extensions greater than standard, add the increase to the net stroke to obtain the 'basic length'.). Calculate the load imposed for the compression application by multiplying the full bore area of the cylinder by the system pressure, or by referring to the Push and Pull Force charts on page 7. 4. Using the Piston Selection Chart, opposite, look along the values of 'basic length' and 'push force' as found in and above, and note the point of intersection. The correct piston rod diameter is read from the curved line above the point of intersection. For tensile (pull) loads, the rod size is selected by specifying standard cylinders with standard rod diameters and using them at or below the rated pressure. inphorm For accurate sizing, please refer to the European cylinder inphorm selection program HY07-60/Eur.

Stroke Factors Piston Selection Chart Push Force (kn) Log Scale Long Strokes and Stop Tubes For long stroke cylinders under compressive (push) loads, a stop tube should be used to reduce bearing stress. The required length of stop tube is read from the vertical columns on the right of the chart by following the horizontal band within which the point of intersection lies. Note that stop tube requirements differ for fixed and pivot mounted cylinders. If the required length of stop tube is in the region labelled 'consult factory', please submit the following information: When specifying a cylinder with a stop tube, please insert an S (Special) and the net stroke of the cylinder in the order code and state the length of the stop tube. Note that net stroke is equal to the gross stroke of the cylinder less the length of the stop tube. The gross stroke determines the envelope dimensions of the cylinder. Cushion Sleeve Stop Tube.

Cushioning An Introduction to Cushioning The option of cushioning is recommended as a means of controlling the deceleration of masses, or for applications where piston speeds are in excess of 0.m/s and the piston will make a full stroke. Cushioning extends cylinder life and reduces undesirable noise and hydraulic shock. Cushions can be supplied at the head and/or cap ends of a cylinder without affecting its envelope or mounting dimensions. Standard Cushioning Where specified, HMI and HMD cylinders use cushions which are profiled to give efficient, progressive deceleration. Final speed may be adjusted using the cushion screws. The head and cap cushion performance for each bore size is illustrated in the charts on page. Note that cushion performance will be affected by the use of water or high water-based fluids. Please consult the factory for details. Alternative Forms of Cushioning Special designs can be produced to suit applications where the energy to be absorbed exceeds the standard cushion performance. Please consult the factory for further details. Cushion Length HMI/HMD cylinders incorporate the longest cushion sleeve and spear that can be accommodated within the standard envelope without reducing the rod bearing and piston bearing lengths see table of cushion lengths on page. Cushion Calculations The charts on page show the energy absorption capacity for each bore/rod combination at the head (annulus) and the cap (full bore) ends of the cylinder. The charts are valid for piston velocities in the range 0. to 0.m/s. For velocities between 0. and 0.5m/s, the energy values derived from the charts should be reduced by %. For velocities of less than 0.m/s where large masses are involved, and for velocities of greater than 0.5m/s, a special cushion profile may be required. Please consult the factory for details. The cushion capacity of the head end is less than that of the cap owing to the pressure intensifi cation effect across the piston. The energy absorption capacity of the cushion decreases with drive pressure, which in normal circuits is the relief valve pressure. inphorm Cushioning requirements can be calculated automatically for individual cylinder/load combinations using the European cylinder inphorm selection program HY07-60/Eur. Formulae Cushioning calculations are based on the formula E = /mv for horizontal applications. For inclined or vertically downward or upward applications, this is modified to: E = /mv + mgl x 0 - x sinα (for inclined or vertically downward direction of mass) E = /mv mgl x 0 - x sinα (for inclined or vertically upward direction of mass) Where: E = energy absorbed in Joules g = acceleration due to gravity = 9.8m/s v = velocity in metres/second l = length of cushion in millimetres (see page ) m = mass of load in kilogrammes (including piston, rod and rod end accessories, see pages and ) a = angle to the horizontal in degrees p = pressure in bar Example The example shows how to calculate the energy developed by masses moving in a straight line. For non-linear motion, other calculations are required; please consult the factory. The example assumes that the bore and rod diameters are already appropriate for the application. The effects of friction on the cylinder and load have been ignored. Selected bore/rod 60/70mm (No. rod) with cap end cushion. Pressure = 60 bar Mass = 0000 Velocity = 0.4m/s Cushion length = 4mm α = 45 Sinα = 0.70 E = /mv + mgl x 0 - x sinα E = 0000 x 0.4 + 0000 x 9.8 x 4 x 0.70 0 E = 0 + 85 = 65 Joules Note that, as velocity is greater than 0.m/s, the energy absorption figures obtained from the charts on page should be reduced by % see Cushion Calculations, opposite. Comparison with the cushioning chart curve for this cylinder shows an energy capacity for the cap end of 5600 Joules. Reducing this by % gives a capacity of 400 Joules, so the standard cushion can safely decelerate the 65 Joules in this example. Where cushion performance figures are critical, our engineers can run a computer simulation to determine accurate cushion performance please contact the factory for details. 0
Cushioning Cushion Energy Absorption Capacity The cushion energy absorption capacity data shown below is based on the imum fatigue-free pressure developed in the tube. If working life cycle applications of less than 0 6 cycles are envisaged, then greater energy absorption figures can be applied. Please consult the factory for further information.

Pressure Limitations Pressure Limitations Push and Pull Loads Where a piston rod is in compression (push load) and attachments are securely butted to the rod shoulder, fatigue is not an issue. Under pull load conditions, the threads between the piston and piston rod may be subjected to full load variations. Under these conditions, fatigue failure must be considered. Most piston rod options are fatigue free at 0 bar. The charts below show the fatigue life profiles of only those piston rods which are affected by fatigue at or below the 0 bar nominal pressure. Fatigue Life of Piston s under Pull Load Conditions Style 4 Double ded Cylinders The method of attachment of the piston rods to the piston in double rodded cylinders results in one rod being stronger than the other see page. The pressure limitations for the stronger rod are identical to those shown on the charts for the equivalent single rod assembly. The chart for the double rod cylinder style 4, below, applies to the weaker rod only. Note: Curves are labelled according to bore size and rod number, eg: 00/ is a cylinder with 00mm bore, fitted with a No. rod. Style 9 Style 7 Double Style 4
Ports, Locations and Piston Speeds Port Types Series HMI and HMD cylinders are supplied with BSP parallel threaded ports or metric threaded ports to DIN 85 Part or ISO 649, spotfaced for sealing washers. For higher speed applications, oversize ports or additional ports are available. mm and mm Cylinders The head depth is increased by 5mm to provide the necessary thread length. At the cap ends of cylinders with oversize ports, 0mm high port bosses are fitted. Note that Y and PJ dimensions may vary slightly to accommodate oversize ports please contact the factory where these dimensions are critical. Port Size and Piston Speed The tables opposite show piston speeds for standard and oversize ports and connecting lines where the velocity of the fluid is 5m/s. If the desired piston speed results in a fluid flow in excess of 5m/s, larger lines with two ports per cap should be considered. Parker recommends that a flow rate of m/s in connecting lines should not be exceeded. Speed Limitations Where large masses are involved, or piston speeds exceed 0.m/s and the piston will make a full stroke, cushions are recommended see page 0. For cylinders with oversize ports and with a fluid velocity exceeding 8m/s into the cap end, please contact the factory with details of the application. Port and Cushion Adjustment Location The table below shows standard positions for ports, and cushion adjusting screws where fitted. For cylinders up to mm bore, a cartridge type adjuster is fitted which may protrude by up to mm on mm and mm bore cylinders. Above mm bore, a flush fitting socket-headed adjuster is used; these may also be fitted to smaller cylinders if mounting space is critical. 4 00 60 00 4 00 4 4 60 4 00 4 Port Size BSP/G inches Port Size Metric Standard Cylinder Ports of Connecting Lines Cap End Flow in l/min @ 5m/s Not to DIN 4 554 0mm high port bosses fitted at cap end ISO 649 ports are not available on some bore/rod combinations 4 Consult factory available on certain bore sizes only.

It is standard policy to fit a cylinder returned for repair with those replacement parts which are necessary to return it to 'as good as new' condition. Should the condition of the returned cylinder be such that repair would be uneconomical, you will be notified. * Seal Groups Ordering The part numbers shown in the tables above are for Group seals, denoted by the last character of each part number. For Group, 5, 6 or 7 seals, substitute a '', '5', '6' or '7' for the '' at the end of the number sequence. All dimensions are in millimetres unless otherwise stated. 7
