N O R G R E N Norgren's advanced cushion design features a unique, one-piece, nitrile compound seal that is captured within a precision machined groove. This allows both linear and radial "float" of the cushion seal which virtually eliminates problems associated with misalignment. Integral flow paths molded in the periphery of the seal provide exceptionally fast "out of cushion" stroke reversal without the use of ball checks. Operating Temperatures: Series A & J -20F to 200F (-29C to 107C) with Viton Seals -20 F to 400 F (-29 C to 204 C) Operating Pressure: 250 PSIG Air (17.2 Bar) 400 PSIG Hydraulic (27.6 Bar) A Bore Sizes: 1-1/2", 2", 2-1/2", 3-1/4", 4", 5", 6", 7", 8" J Bore Sizes: 1-1/2", 2", 2-1/2", 3-1/4", 4", 5", 6", 7", 8", 10", 12" Supply: Filtered compressed air to 250 PSI Petroleum based hydraulic fluid to 400 PSI Lubrication: None required Norgren Air Cylinders are rated for "no lube added" service. All internal compo- nents are lubricated at time of assembly with a Teflon based grease. Side Loading: Cylinders are specifically designed to push and pull. Side loading (mis- alignment) of the piston rod should be avoided to ensure maximum operating performance and life. Care should be taken during installation to properly align the load to be moved with the center line of the cylinder. The use of a rod alignment coupler is strongly recommended whenever possible. A Materials: Head and End Caps: black anodized 6061-T6 aluminum Tube: 6063-T832 aluminum, clear anodized O.D., hard coat anodized I.D. Rod: hard chrome plated steel Piston: machined high-strength aluminum alloy Rod Bearing: oil impregnated sintered iron Seals: nitrile rod seal, urethane rod wiper, nitrile piston seals, nitrile tube end seals Tie Rods: high-tensile strength steel J Materials: Head and End Caps: precision machined steel Tube: 6063-T832 aluminum, clear anodized O.D., hard coat anodized I.D. Rod: hard chrome plated steel Piston: machined high-strength aluminum alloy Rod Bearing: oil impregnated sintered iron Seals: nitrile rod seal, urethane rod wiper, nitrile piston seals, nitrile tube end seals Tie Rods: high-tensile strength steel Air Cylinder Selection: The proper application and selection of a cylinder requires full consideration of the fol- lowing: the fluid medium, operating pressures, mounting style, length of stroke, type of rod connection to the load, thrust or mounting ten- sion on the rod, mounting attitude, speed of the stroke and how the load motion will be stopped. The data that follows provides the necessary information in the evaluation of an average application and will help you in selecting the proper cylinder model and size for your particular application. Note : 1-1/2", 2", 2-1/2", 3-1/4", 4" and 5" bore cylinders with 1/2" to 2" strokes will be furnished with a short head cushion sleeve and short cap cushion spear. Only available on 5/8" and 1" rods. The above specification applies to Series A and J cylinders with optional non-adjustable or adjustable cushions. Series A & J Fixed Cushions Piston and rod assembly for 1-1/2" thru 5" bore cylinders with 1/2" to 2" stroke. Figure 2 shows spear exiting cushion seal.
