Flat-II® cylinders are ideal in applications where rotation is prohibited and space is minimal. Non-rotation is achieved using dual piston rods and a rod end block that ensures the rods work in tandem.  The Flat-II® eliminates the need for external alignment devices, such as guides, rods, and alignment posts or pins.Bore sizes:  3/4", 1-1/16", 1-1/2", 2"304 stainless steel body prevents corrosionStandard oil impregnated bronze rod bushingStainless piston rodPrecision machined anodized aluminum headsMaximum Pressure:  200 PSI (air only)
