SMA Aluminum Cylinders PNEUMATIC TO 200 PSI HYDRAULIC 250 TO 400 PSI Non shock /8,, 2, 3 BORE SPACE SAVING AND CONVENTIONAL DESIGNS REPAIRABLE Very high quality Pancake type cylinders with all of the engineering features you need to outpace the competition generous bearing lengths, rod wipers, chromed shafts, superior seals and materials throughout. PLUS Cylinders of conventional length with longer bearings and increased distance between support points which provide exceptional service where space permits. U cup piston optional. A GRAPH OF CYLINDER LENGTH vs QUALITY... Conventional Pancake Too short to provide rod wipers, adequate bearing length, and quality seals. Length too short to provide end caps of sufficient strength for many applications. Piston rod wrench flats virtually unusable without special thin wrenches. Suitable for light duty pneumatic applications only. SMA Short Mount Common sense engineered to the shortest length possible without sacrificing areas critical to high performance. Excellent for both pneumatic and hydraulic service. SMA Conventional Mount Premium material in generous proportions yet small enough to fit. Crimped Stainless Non Repairable Although significantly longer, they fall short in design and materials. N.F.P.A.

SMA DESIGN FEATURES Piston rod is hard chrome plated type 303 stainless Rod extension/wrench flats are long enough to fit standard wrenches. Heavy duty polyurethane or viton rod wipers prevent damaging contaminants from entering the critical rod seal/rod bushing area. Pneumatic rod seal is a "longlife" nitrile cup. Hydraulic rod seal is pressure energized and extra long wearing for improved sealability. Heavey /8" wall aluminum tube is hard anodized on the interior to provide a scratch and wear resistant surface. Brass or aluminum piston is attached with a high strength threaded joint. Composite rod bushing has high temperature capability and excellent chemical resistance. Solid lubricant fillers provide excellent wear characteristics for non-lube service. The bearing is inboard of the wiper and seal, away from the environment Reduce noise and fatigue problems such as rod breakage with urethane/nitrile shock pads. Add /4" to the cylinder length for each pad. Pneumatic use only to 80 F. Optional wick provides teflon lube for non-lube service on O ring piston. Standard piston seal is large cross section O ring. Compounds are carefully selected for maximum cycle life. Optional U cup piston seals with teflon wear strip stretch the limits of service even further. Reduce friction and operate without lube in the severest applications while extending or eliminating the service interval. If space permits for applications involving side loads or long strokes, select SMA, 2, 3, 5, 7, 8, 9, 2, 3, 9, 2, 23, 25, 28 which have extra long bearings with added space between support points. Strokes longer than the maximum listed in the ordering procedure can be produced but careful consideration must be given to how the cylinder is applied how well is the load supported or guided, is the cylinder used in push or tension, is the cylinder vertical or horizontal, etc. Consult factory on all strokes longer than standard. Stroke increments other than standard can also be made. Special lengths are generally available in a few days and are priced as "non-standard" strokes. 5

By pressuring Port, 3, or 4, any combination of stroke and total stroke may be achieved. Port 2 is a vent port only for Cylinder. In hydraulic applications it should be connected to a tank by a drain line. Pressurize Port and Cylinder will extend pushing Cylinder 2 by the same amount. Then pressurize port 3 and Cylinder 2 will extend further to its maximum length. Pressurize Port 4 and both cylinders will retract. *Stroke of Cylinder 2 = TOTAL Stroke EXAMPLE: If Cylinder extends 2 when port is pressurized, it will also push Cylinder 2 by 2. If, when Port 3 is pressurized, Cylinder 2 moves an ADDITIONAL. Then the total stroke of Cylinder 2 is 2 + = 3.

BORE SMA ALUMINUM Tandem models 200 PSI MAX. AIR 400 PSI MAX. HYD. Non shock PORT PORT 2 PORT 3 PORT 4 Tandem Cylinders are two in-line cylinders of the same stroke length with a common cap. Both pistons are attached to a common rod. By simultaneously pressurizing Ports and 3 or 2 and 4, the force on the piston rod is nearly doubled. This can be useful when more force is required, but the diameter of the cylinder cannot be increased due to size restrictions. Tandem cylinders can can also be used as part of an air/oil system. Fill the front cylinder (Cyl.2) with oil and pipe its ports (3 & 4) in series using one or two flow controls. Using the rear cylinder (Cyl. ) as an air powered driver, meter the oil from end to end on Cylinder 2. This will provide smooth, precise control of piston rod motion at all speeds. A small reservoir of oil at 0-20 psi should be connected to Cylinder 2 if oil loss or expansion/contraction due to heat are a concern.

Bore SMA Volumetric Pump VOLUMETRIC PUMPS measure and dispense specific volumes of fluid with compressed air. These tandem type cylinders have two pistons connected to a common rod. The air powered driver section is normally reciprocated with a four way valve. The inlet/discharge port is connected to a fluid supply line and a discharge line, both of which contain a check valve. On each stroke the pump section first draws in a specific volume of fluid from the supply line, and then forces it out the discharge line as both check valves shift. Maximum pressure of discharge fluid is approximatly equal to the air pressure on the driver section. Standard construction materials are the same as all SMA cylinders anodized aluminum tube and end caps, stainless rod, and brass pistons.

Then add a dash (-) and the part number for cylinder #2 skipping the "bore" and "mounting style" codes and beginning with the "type" code. Example: Cylinder SMA8COE R Cylinder 2 C6EF3 R 33
