Model: A/J
Norgren NFPA Series A aluminum and J steel pneumatic cylinder family, including EA and EJ Ecology series. Component materials, pressure, temperature and cushion conditions depend on the series, bore and seals.
| Pressure condition by series | A/J: 250 PSIG filtered compressed air under non-shock condition; EA/EJ: 150 psi maximum (medium not specified in the original note); J/EJ only: 400 PSIG petroleum-based hydraulic fluid under non-shock condition (footnote applies). Both the 150 psi maximum note and the 400 PSIG hydraulic footnote name EJ; the applicable pressure for the selected configuration requires confirmation. |
| Operating temperature condition | Series A/J -20°F to 200°F; -20°F to 400°F with FKM (Viton) seals |
| Bore choices (inch) | 1-1/2, 2, 2-1/2, 3-1/4, 4, 5, 6, 7, 8, 10**, 12** (original ** marks retained; their additional conditions are unconfirmed) |
| Head and end-cap materials | A/EA: black anodized aluminum alloy; J/EJ: precision machined steel |
| Tube material and bore conditions | A/EA 1-1/2–12 inch and J/EJ 1-1/2–2-1/2 inch: aluminum alloy, clear anodized O.D. and hard coat anodized I.D.; J/EJ 3-1/4–12 inch: steel tube with hard chrome plated I.D. |
| Piston materials | A/EA: machined high-strength aluminum alloy; J/EJ: steel |
| Piston rod material | Hard chrome plated steel |
| Rod bearing material | Oil impregnated sintered iron |
| Seal and wiper materials | Rod, piston and tube end seals: NBR (nitrile); rod wiper: urethane |
| Tie rod material | High-tensile strength steel |
| Lubrication conditions | No lube added service; internal components lubricated at assembly with Teflon® based grease |
| Head and cap cushions | Optional; adjustable captive cushion needle |
| Cushion seal rod-diameter conditions | 5/8 inch and 1 inch rod diameter: NBR (nitrile) seals; rod sizes 1-3/4 inch and larger: urethane seals are standard |
| Wear ring material | Reinforced Teflon® compound with polyphenylene sulfide |
