Series CS2 air cylinder is a double acting, non-lube air cylinder. Aluminum die-cast is used for both the rod and head covers, which means a maximum weight reduction of approximately 50% *. This series is available in bore sizes 125mm, 140mm and 160mm with maximum strokes up to 1600mm *. Air cushions are standard on both ends. Other options include auto switches, rod boots, and Rc, NPT or G thread types.
