KG series air cylinders/valve actuators come with aluminum tubes standard on 112- to 8-in. bore cylinders (with the exception of 7-in. bore). Aluminum tube is hard coat anodized with an electrochemical process that produces a very dense surface of aluminum oxide to offer extreme hardness (60 RC.), high wear and corrosion resistance, and low coefficient of friction. They are available in 17 bores sizes ranging from 112 to 24 in. and piston rod diameters range from 58 to 312 in.
