Air cylinders feature a V-seal design that prevents seal collapse and blow-by, ensuring constant contact with the cylinder barrel. The reversible piston provides dimensional consistency, and standard cylinders are interchangeable with cylinders having options such as bumpers, or a magnet used to actuate a reed switch. The cylinders feature stainless-steel barrels and piston rods and oil-permeated, ball-sized rod bushings.
