Pneumatic CylindersDeveloping Specificationsz Calculating the Proper Bore SizeA cylinder’s bore size determines the force it will produce at a given supplypressure. The weight of the load or the clamping force required will largelydetermine the force requirements of the cylinder, and hence, the boresize required. But before determining the appropriate bore size you mustcompensate for air pressure drop, packing friction and load variations usingthe following computation:A) Compensating for Pressure Drop – Decrease the line pressure valueby 15 p.s.i. This compensates for pressure drop in the system. Operating pressure (psig) Line pressure (psig) less15 (psig) pressure dropAir pressure atsource. 95 psiDownstream pressurebecause of pressureloss in lines: 80 psipressure loss in linesPackingFrictionLoadFrictionThis illustration shows a pressure loss of 15 PSI through the airlines and pointsout friction factors, both of which must be compensated for. Example: If the line pressure is 95 (psig), subtract 15 (psig) toobtain 80 (psig) operating pressure (for sizing purposes)B) Compensating for Packing Friction – Before you begin selecting a cylinder you already know the weight of the loadyou must move or the clamping force you must apply. Multiply this force or load value by 1.25. This compensatesfor packing friction and load variations. (If speed is of concern for your application, multiply the force value by 2.0.)Force required (in pounds) 1.25 x load (or required clamping force) Example: If cylinder must move 100 pound load, multiplying 100 pounds by 1.25 125 pounds forcerequired.Now, at the top of the chart on the next page, find the column with the operating pressure calculated in “A” above (inthis example, 80 psig). Go down that column until you find the force requirement calculated in “B”, above (or the nexthigher value). Note that the force values in bold type represent the extend force while those in standard type representretract force (retract force is lower because the rod reduces the effective piston area). Choose the appropriate value,then go to the Cylinder Bore column to find the bore requirements for your application.Now that you know the cylinder bore size that will produce the force required for your application, go to page 7 todetermine rod size requirements. Air consumption for each cylinder bore size can be found in the chart below.z Cylinder Air ConsumptionTo calculate the air consumption of a cylinder, multiply the total inches of stroke(extend plus retract) by the cycles per minute times the SCFM factor from thechart below. To find the SCFM factor, find your gauge pressure in the left handcolumn. Next, find your cylinder bore size in the chart. Where the two intersect,read down to the SCFM factor at the bottom of the chart.2-inch cylinder251 poundsof force5/8-inch diameter227 pounds of forceGiven equal pressure on both sides of a piston, the surface area onthe extend side will provide greater force.arotechsupport@irco.com (800) 495-0276 / Pneumatic Cylinders AROzone.com5

Pneumatic Cylindersz Rod DiameterA) Use the stroke factor tableto find the proper multiplierbased on the mountingconfiguration and rod endconnection used.B) Multiply your requiredworking stroke length bythe factor you found fromthe stroke factor table inStep A. Note: if you requirea rod or thread extensionin your application (Longerthan standard) add the extralength(s) to your requiredworking stroke length andthen multiply by the strokefactor found in Step A, theresult of this arithmetic is the“L” Value.C) Use the piston rod diameter/stop length chart to completeyour cylinder specification.Find the approximate “L”value (determined in StepsA & B) on the left side ofthe chart. At the bottomof the chart, find the force(thrust) required for yourcylinder. Reference the boreselection sizes table on theprevious page to determinebore size, rod diameter orforce at various PSI. Findthe intersection of the “L”value (Horizontal) line withthe force in pounds (Vertical)line. The intersection shouldbe on, or to-the-left of thediagonal (rod diameter) line.The diagonal (rod diameter)line indicates the correctpiston rod diameter for yourapplication.Note: If your “L” valueforce lines intersect above,or to-the-right of a diagonalline, find a cylinder withthe next larger piston roddiameter to avoid prematurecylinder wear or failure.STROKE FACTORCYLINDER RIGIDLY MOUNTEDROD YGUIDEDL-MOUNTS, SIDEFRONT ORTAPPED SIDEREAR FLANGEEND LUGSMOUNTING NUTSCYLINDER PIVOT EVIS EYE. EDNote: Remember, long ,slim piston rods may buckle when subjected to a heavy push load.Note: When a stop tube is needed, a minimum 2” length is required on all Economaircylinders with Lip packings, and in 4”, 5”, 6” and 8” Provenair cylinders.z Stop Tube RequirementsAvailable in Economair & Provenair OnlyOccasionally, an application will require a stop tube Stop tube length is determinedby “L” value. If your “L” value (from Step B) is 40 or greater, find the correct stoptube length for your cylinder on the right side of the piston rod diameter/stop lengthchart. The recommended stop-tube length is shown above the “L” value line.Note: I f “L” value is 39, no stop tube is required. If “L” value is 40-49,a 1” stop tube is recommended.If “L” value is 50-59, a 2” stop tube is recommended, etc.arotechsupport@irco.com (800) 495-0276 / Pneumatic Cylinders AROzone.com7
Pneumatic Cylindersz OptionsAdditional options required will help determine which cylinder series will be selected: Stainless steel piston rods are beneficial in corrosive environments. Stainless steel rods are standard on Micro-Air andSilverair Series. Stainless Steel rods are options on Economair and Provenair Series. Cylinder cushions are designed to reduce the shock experienced at the end of the stroke by reducing piston speed thelast fraction of an inch of stroke. Cylinder cushions are available in Economair and Provenair Series, only.z Packing shape and material affect cylinder performance: O-Ring packings are good, general purpose packings, but they require more breakaway force than other packingshapes. O -Ring – Low Friction packings provide the effective sealing characteristics of Buna N with the low frictioncharacteristics of PTFE. This design is effective where the cylinder must operate at low pressures. U-Cup packings offer low breakaway friction and better sealing characteristics at low pressure than O-Ring packings.U-cups are wear compensating seals; they offer longer wear life than O-rings. U -Cup – Self Lube (“Slippery Seals”) packings are ideal in applications where air line lubrication cannot be used.This packing design helps reduce cylinder “chatter” in low pressure applications and it offers the same sealingcharacteristics as Buna N.z Packing GO-RINGO-RINGU-CUP-SELF-LUBE(“Slippery ureToleranceAvailabilityPTFE overBuna N O-Ring SealBuna NViton GoodMedium0 to 180 FEconomairGoodGoodHighHigh0 to 180 FUp to 300 FPremair, Micro-Air, EconomairPremair, Micro-Air, EconomairNitrileBuna NVitonVery GoodVery GoodVery GoodLowMediumMedium0 to 180 F0 to 180 FUp to 300 FEconomair, ProvenairEconomair, ProvenairEconomair, ProvenairNote: W hen applying rod cylinders, there must be no side load or bending stress at any point along the rod. Applications which induce side load and/or bending stress will damage packings, bushings, piston barrels,piston rods and cushion bosses. When metal parts are damaged, seal and packing replacement is an inadequate repair. The elastomers will quickly become damaged. Inspect and replace all worn or damagedparts when rebuilding cylinders.8AROzone.com Pneumatic Cylinders / (800) 495-0276 arotechsupport@irco.com
Micro-Airz FeaturesSeries 01Micro-Air Cylinders are ideal for small part positioning, clamping and ejecting.

M icro-Air Cylinders are repairable. Service kits are available to extend the useable lifeof the cylinder. Micro-Air Cylinders operate on air pressure to 200 p.s.i. (14 bar). A tough littlecylinder that can handle the pressures! Superior performance over a wide temperature range – 0 to 180 F (-18 to 82 C),even to 300 F (149 C) when Viton seals are used (consult factory). Micro-Air Cylinders have superior wear characteristics, thanks to the hard coatedaluminum tubing I.D. In addition to an internal hardness of 60 Rockwell C, the barrelhas an internal finish of 16 microinches or better. Micro-Air Cylinders are equipped with Series 303 stainless steel piston rods forcorrosion resistance. Also, the ground and polished finish on the rods minimizesfriction, providing longer packing life. Micro-Air Cylinders provide greater durability than disposable cylinders.
