A Series Piston: Machined solid aluminum alloy, light-weight for low inertia, yet strong. Threaded piston is installed with high strength threadlocker adhesive then staked to the piston rod. J Series Piston: Machined solid steel, for high strength. Threaded piston is installed with high strength threadlocker adhesive then staked to the piston rod. Piston Rod: Hard chrome plated high-tensile steel, ground and polished. Rod Bearing: External removable threaded steel bearing housing (black oxide finish), with an oil-impregnated sintered iron rod bearing. Rod Seal: Nitrile lip-type seal is pressure energized and wear compensating for durability and long life. 1 2 3 Ultra Cushion Seals: Advanced design features a unique, one-piece, compound seal of nitrile* captured within a precision machined groove. Linear and radial "float" of the cushion seals eliminates misalign- ment. Ultra Cushions provide exceptionally fast "out of cushion" stroke reversal. (Head and Cap Cushions are optional.) *Nitrile seals on the 5/8" & 1" rod diameter. For rod sizes 1-3/8" and larger, urethane seals are standard. O-Ring Tube Seal: Buna is standard. (Viton is optional.) Tie Rods: High-strength steel maintains uniform compression on tube end seals. 5 6 Adjustable Captive Cushion Needle: One- piece stainless steel cushion needle with fine threads is held captive by a stainless steel press-in retaining washer. This allows for safe and precise adjustment of the cushion. 7 9 8 A Series Head/Cap: Precision machined from alloy aluminum, then anodized for corrosion resistance (black finish). J Series Head/Cap: Precision machined from steel, then black oxide finished 1-1/2" to 2-1/2" bores. Painted black finish on 3-1/4" to 12" bores. 4 A Series Cylinder Tube: High-strength aluminum alloy ideally suited for air service. The tube is clear anodized on the O.D. and hard anodic coated on the I.D., resulting in a smooth, file hard (60RC), corrosion and score resistant surface finish. 11 Application Information Series A and J NFPA interchangeable aluminum air cylinders are offered with a variety of accessories, standard and optional equipment to meet your application needs. The addition of a Teflon wear ring to the outer perimeter of the piston permits us to guarantee its operation against failure due to lack of lubrication for ONE FULL YEAR, regardless of cycles! Standard non-cushioned Series A and J cylinders are recommended for applications that require full bottoming of the piston and where the noise emitted by the metal-to-metal impact between the piston and cylinder end caps is tolerable. We recommend that optional non-adjustable cushions be added for piston speeds ranging from 15 to 30 in/sec and adjustable cushions for speeds exceeding 30 in/sec. 2 1 7 3 6 4 5 8 9 4 5 13 12 11 10 9 6 12 Wiper Seal: Lip-type urethane wiper seal keeps contaminates from getting into cylinder by aggressively wiping foreign materials from the piston rod, enhancing the rod seal life. Piston Seals: Long-wearing nitrile seals. Wear Ring: Rein forced Teflon compounded with polyphenylene sulfide provides supreme wear and excellent bearing support. 12 13 10 J Series Cylinder Tube: High- strength aluminum alloy 1-1/2", 2", 2-1/2" bore anodized on the O.D. and hard coat I.D. Steel cylinder tube hard chrome plated I.D. 3-1/4" to 12" bore.
