c20 series cast iron pneumatic cylinders

• head and cap - pressure rating 200 psi fine grain, high tensile cast iron heads and caps are the finest that modern foundry skill can produce. they are machined to exacting standards.
• piston rod - piston rods have a minimum expected yield of 100,000 psi. they are ground, polished, and hard chrome plated for wear and corrosion resistance. four wrench flats are standard.
• tube - the tube is a high tensile, special aluminum alloy with a hard anodized finish. the file-hard finish offers long life and amazing lubrication holding properties.
• tie rods - maximum strength is obtained through a pre-stressed tie rod assembly.
• piston - pistons are machined from a fine grain alloy cast iron. they are of one piece design to give full thickness bearing and engineered for fast, positive inflation of seals.
• cushion insert seals - cushion insert sandwiched between the tube and head (or cap) is sealed with a pressure-activated o-ring.
• tube end seals - static seals at tube ends are confined, precision cut gaskets.
• piston seals - modified u-cup seals are buna-n compound. they are self-adjusting to pressure and wear and their design permits simple replacement – no need to disassemble the piston from the piston rod.
• rod bearing - the replaceable rod bearing is made of oil impregnated sintered bronze for lubricated long life.
• rod wiper - synthetic wiper, steel encased, is designed to wipe off abrasive dust and contaminates on the retract stroke to insure long life for packings, rod bearing, and piston rod. this type of wiper is efficient, has low friction, and can be replaced without disassembly of the cylinder.
• rod seal - modified u-cup design offers long life with minimum friction. it is self-adjusting to pressure and wear. seal material is a standard buna-n compound. the rod seal can be replaced without disassembly of the cylinder.
• cushion adjusting screw - is o-ring sealed and can be rotated to any position for easy accessibility.
