Cylinders, Air Manufacturers

Air cylinders are driven by pressure differential in the cylinder chambers. One side of a piston flange may be pressurized to provide force and motion with a spring providing return force after pressure is released or both sides can be alternately pressurized for bi-directional powered motion. Air cylinders are used in many positioning, actuating and clamping applications and devices. Choices for cylinder style includes tie rod, smooth body, pancake, rectangular, and multiple bore. Tie rod cylinders are held together by exterior tie rods, they are usually in a rectangular bolt pattern. In a smooth body cylinder style, the cylinder body encases the piston. A pancake cylinder has a shorter length and larger diameter than other styles. A rectangular cylinder is encased in a rectangular box shape frame. In a multiple bore cylinder two or more bores and pistons are combined or stacked in same cylinder. The cylinder can be single or double action. Single action cylinders frequently incorporate a return spring to the un-powered position. In a double action analyzer both sides of piston can be pressurized for reversible motion.
