ISO 6431 Actuators

FAQ2R Series

Built for ISO 6431 Dimensional Compliance and Reliability

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.

Key Specifications

  • Bore sizes: 32, 40, 50, 63, 80, 100, 125 millimeters
  • Strokes: up to 1,000 millimeters
  • Magnetic piston standard in all sizes
  • Single and double-rod versions
  • ISO 6431 dimensional interchange
  • VDMA24562 compliance
  • Adjustable air cushions at both ends
  • Machined male rod thread with jam nut standard
  • Hard anodized aluminum cylinder tube ID and OD with painted end caps
  • Operating pressure: 1 MPa, 150 psi
  • Operate with or without additional lubrication


Technical Advantages
  • An aluminum alloy magnetic piston and machined male rod thread with jam nut are standard features.
  • The standard annular piston magnet is permanently bonded into the grooved piston for reliability. The polarized permanent magnet, made of rubber bonded barium ferrite, is very stable and unaffected by shock. Under normal use it will remain magnetized indefinitely.
  • The FAQ2R Series has a new extruded body, made of hard-anodized aluminum alloy, designed for flush mounted sensors. The sensors, when combined with an adapter, clamp rigidly to an extruded mounting slot and can clamp anywhere along the length of the cylinder, ensuring precise position sensing.
