PURPOSE: An equalizer cylinder is provided to improve the workability when repeating the forward and reverse operation of sliders by a same distance without any deviation when pistons having a phase difference. CONSTITUTION: An equalizer cylinder includes a single cylinder block(10) having a plurality of cylinder chambers(11) formed with air ports, and assembling screw-holes(13) formed at both side surfaces and a top surface, a plurality of pistons(20) received in the plurality of cylinder chambers, a phase difference connection element(30) connecting the pistons with a same distance of no deviation while the pistons having a phase difference, thereby providing forward and reverse operation, a plurality of sliders(40) mounted to the pistons and having jig holders(41) formed with assembling holes(42) for attaching jigs and slide elements(43) formed with bearing grooves(44) longitudinally and assembling screw-holes(49) for attaching jigs, the jig holders being perpendicular to the slide elements, a plurality of guide rails(50) having U-shaped guide grooves(51) for guiding the forward and reverse operation of the sliders, bearing grooves(52) formed at both sides longitudinally facing to the bearing grooves of the slide elements, and assembling screw-holes(53) in conformity with the assembling screw-holes of the cylinder block to be coupled with the cylinder block by screws(54), a plurality of metal roller bearings(61) crossed by 90° along the bearing grooves of the guide grooves and the bearing grooves of the slide elements, and spacer bearings(62) formed of resin and interposed between the roller bearings.
