About the Airtac SAID32 Double Rod Cylinder SAID32AX270S
The AirTAC SAID32X270-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 270mm stroke. Because a rod exits both end covers, the annulus area is identical on each side, yielding perfectly symmetric thrust. It generates 345N of force in both extend and retract directions at 0.5MPa (483N at 0.7MPa).
Equipped with a magnet (-S), this unit supports AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves. The rod is constructed from SUS420J2 stainless steel (option A) for enhanced corrosion resistance, and the piston travels at 30-800mm/s on PT-threaded G1/8 ports.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID32 Double Rod Cylinder SAID32AX270S Is Used
Symmetric Force Transfer
Drives a workpiece back and forth with identical 483N thrust in both directions, ensuring consistent clamping and pushing without speed variations.
Dual-Side Position Sensing
Utilizes the rear protruding rod to mount a physical cam or flag, triggering DMSE electronic sensors from the opposite end of the primary tooling.
Anti-Rotation Slides
Leverages the double-rod guidance to prevent piston twisting during vertical lifting operations, maintaining strict linear motion without external guides.
Is the Airtac SAID32 Double Rod Cylinder SAID32AX270S the Right Cylinder?
Select this 32mm bore when an application requires equal push and pull forces, such as a 483N transfer load at 0.7MPa. If your setup needs less force, stepping down is not an option in this series, but stepping up to a 40mm bore raises the bidirectional output to 528N at 0.5MPa. The twin-rod design provides superior anti-rotation stability compared to a single-rod SAI, allowing a cam or position flag to be mounted on the rear rod extension.
This cylinder uses a reduced ISO 15552 mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. At a 270mm stroke, the extended double rod length requires careful alignment to prevent rod-bearing bending; an external guide is recommended for heavy lateral loads. Note that the adjustable air cushions only decelerate the piston near stroke end and do not hold the load if air pressure is lost.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID32 Double Rod Cylinder SAID32AX270S FAQ
Because the rod occupies both sides of the piston, the effective area is equal in both directions. It provides 345N of force at 0.5MPa, 483N at 0.7MPa, and 621N at 0.9MPa for both extension and retraction.
Yes, it is dimensionally interchangeable per ISO 15552. You can drop it in for other profile-type double-rod cylinders using the standard Basic, FA, LB, or TC mounting interfaces, provided you account for the rear rod clearance.
