ISO cylinders give you the freedom to use internationally compatible mountings and accessories. We updated our FAQ2R Series ISO 6431 air cylinder with a new extruded body to better house flush-mounted sensors while also giving it a clean shape. The single- and double-rod units are built tough with a hard-anodized aluminum cylinder inner and outer diameter plus painted end caps. Each unit comes with an aluminum alloy magnetic piston, adjustable air cushions at both ends and a machined male rod thread with jam nut. Optional Reed and electronic sensors mount securely to an extrusion slot anywhere along the length of the cylinder. The cylinders come in bore diameters from 32 to 125 millimeters, and standard strokes range from 25 to 1,000 millimeters for all bore sizes.
