Premium Quality and Economy in one. Lightweight construction and solid Non-Lube design with proven reliability make the AL4 Series Cylinder the high performance, long lasting, economical choice for your air cylinder applications.

Extruded Aluminum Cylinder Body - Lightweight, unique design provides strength and eliminates areas of contamination. 5" through 8" bore have aluminum tube with steel tie rods.

Piston - Aluminum piston with nylon wear band increases cylinder life, eliminates metal-to-metal contact. Optional magnet* piston for use with reed or solid state switches. Anaerobic adhesive is used to permanently lock and seal the piston to the rod.

*Magnet option must be specified when placing order or piston will be equipped with wear band and seals only.

Heads and Caps - Precision, lightweight aluminum blocks that are anodized for maximum corrosion resistance.

Rod Seal - The Nitrile rod seal is pressure energized, wear compensating and resists abrasion to ensure long life.

Rod Wiper - The Urethane wiper seal wipes away dirt that may have accumulated on the rod, reducing bushing wear.

Rod Bushing - Externally removable, high-density iron, plated rod bushing protects against side loads. The outboard placement of the rod seal ensures lubrication over the full bearing length.

Ports - N.P.T.F. ports are standard.

Cushion Needle Valves - Make precise adjustment quick and easy. Captive cushion design allows for safe cushion adjusting while cylinder is under pressure. Brass material to resist corrosion.

Piston-Rod - Hard chrome-plated and polished piston rod of 100,000 psi yield, high tensile strength steel, case hardened to 50-54 Rc for reliable performance and long rod seal life, less friction.
