Square Flat-II® non-rotating, double acting cylinders provide the answer to applications where rotation cannot be tolerated.  Non-rotation is achieved with dual piston rods and a rod end block that insures the rods work in tandem.  This design eliminates the need for any type of external alignment devices and the square end caps allow for bottom flush or face mounting.Bore sizes:  3/4", 1-1/16", 1-1/2", 2"304 stainless steel body prevents corrosion303 stainless steel tie-rodsStainless piston rodPrecision machined anodized aluminum headsMaximum Pressure:  200 PSI (air only)
