Double Acting, single rod end Cylinders multiply force output 3 Bore sizes 2-1/2" thru 4" Strokes to 4" standard Fabco-Air attaches multiple pistons to a common shaft and provides internal air passages through the shaft to all pistons. When air pressure is applied to the extend port, all pistons are pressurized simultaneously, enabling tremendous thrust forces to be obtained When air pressure is applied to the retract port, only one piston is pressurized. When air pressure is applied to multiple retract ports, higher retract forces are achieved. |
