a series heavy-duty pneumatic cylinders

• pressure rating 250 psi
• the heads, retainers and mountings are machined from steel. the trunnion head, flanges and foot bracket mounts are bolted. pivot and clevis mounts on 1-1/8" bore only, aiso are bolted. side lugs, centerline lugs, and clevis (except 1-1/8" bore), are welded.
• trunnions between heads, front head, and rear head mounts are machined from solid stock. all mounting holes are accurately machined for socket head cap screws.
• piston rods are high tensile steel, and hard chrome plated.
• tubes are high tensile aluminum alloy tubing, hard anodized finish.
• for maximum strength tie rods are made of high tensile steel rods and pre-stressed to eliminate tube seal extrusion.
• rod cartridges are long wearing and easily maintained. they are made of bearing bronze for long life and low friction. dual purpose o-ring seals and maintains tension to prevent longitudinal cartridge motion.
• pistons are made from fine grain alloy cast iron in a one piece piston design secured with self-locking nut.
• piston packings are made of standard commercial buna-n compound, in modified u-cup shape for low friction.
• cushion packings are buna-n modified u-cup which gives positive sealing during cushioning and free flow of air for rapid acceleration.
• rod packings are also made of standard commercial buna-n compound, with modified u-cup design that offers minimum friction and long life. it is self-adjusting to wear and pressure.
• rod wipers are efficient, and long wearing.
