We'll go to work for you! • 3-Position Cylinders 3-Position cylinders are generally used when three distinct rod positions are required from a single cylinder body. Two cylinders are assembled tip-to-tail with a common center head. Using cylinders with two different strokes (the shorter located on the rear cylinder), enables the front rod to be extended from “home” to a positive mid- position or to full extension. • Back-to-Back Cylinders Here two cylinders are mounted back-to- back. They can have the same or different strokes and can be operated independently. This assembly enables you to have four combinations of rods extended or retracted. 1 2 Stage 2 Stage 1 Stage 3 • Multi-Power ® Cylinders (150 psi max) Fabco-Air attaches multiple pistons to a com- mon shaft and provides internal air passages through the shaft to all pistons. Internal baffles divide the cylinder body into separate sections or stages. When air pressure is applied to port #2 of the cylinder illustrated at the right, all three pistons are pressurized simultaneously nearly tripling the thrust. Cylinders can be built with up to four stages enabling thrusts of over 16,000 pounds to be reached! 1 2 3 4 • Tandem Cylinders Tandem cylinders provide nearly twice the force on an equivalent double acting cylinder. Two pistons are attached to a com- mon piston rod. Ports 2 and 4 are pressur- ized simultaneously to nearly double the extend force. Ports 1 and 3 are pressurized to double the retract force.
