Series 1 Cylinders
		Product Detail • NFPA Interchangeable • 1 1/2" - 8" Bores • 250 PSI Pneumatic • 250 PSI Non-Shock Hydraulic Material And Design Specifications Tube: 6063-T832 grade aluminum alloy with hard coated I.D. This anodic coating provides extreme hardness, excellent wear, low coefficient of friction, and high corrosion resistance to ensure longer, trouble-free cycle life. Head and Cap: Precision machined from extruded 6061-T6 grade aluminum alloy. Hard coated as standard on 1 1/2" through 5" bores. (Optional on 6" and 8" bores.) Piston Rod: Hard chrome plated steel ground and polished to a smooth finish. Tie Rods: High strength 1215 grade zinc clear chromate plated steel. Rod Bushing: Continuous cast SAE 660 grade bronze bushing is piloted into the head and is securely held in with an aluminum retaining plate (1 1/2" through 5" bores) to provide maximum load bearing support. Piston: High grade aluminum alloy. Piston Seals: Block-Vee type, Buna N material is furnished as standard. Piston Bearing Strip: A low friction, dimensionally stable nylon wear band constitutes an excellent bearing surface. Rod Seal: Block-Vee type is self-adjusting to ensure proper seal. Rod Wiper: Lip type urethane seal cleans piston rod and prevents foreign particles from entering cylinder. Cushion: Self-adjusting urethane cup moves into the head/cap to insure a positive seal and allows air to meter across the cushion screw. This method provides a fast breakaway and more precise adjustment. (Optional) Tube Seal: Buna N "O" ring in head and cap provides tight seal.
