About the Airtac SAID32 Double Rod Cylinder SAID32X400
The AirTAC SAID32X400 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 400mm stroke. Because the piston rod exits both end covers, the annulus area is identical on both sides, yielding exactly 483N of force in both extend and retract directions at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This configuration uses a standard carbon steel rod and PT tapered port threads. The twin-rod design is ideal for applications requiring rear-rod sensing or dual-side actuation. It shares the same mounting interface as other ISO 15552 cylinders but omits FB, CA, CB, and CR brackets, utilizing only Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
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 SAID32X400 Is Used
Symmetric Transfer
Drives a transfer shuttle with identical force and speed in both directions, ensuring precise timing for mid-stroke positioning without momentum shifts.
Anti-Rotation Slide
The twin rods guide the payload securely, preventing torsional twist on vertical lifts where a single rod would allow the tool plate to drift.
Dual-Side Actuation
Mounts the primary workpiece on the front rod and a mechanical cam on the rear rod to trigger external limit valves during the stroke.
Is the Airtac SAID32 Double Rod Cylinder SAID32X400 the Right Cylinder?
Select this 32mm bore when an application demands equal push and pull forces, specifically 483N at 0.7 MPa. If your mechanism requires less force, stepping down is not an option in this series, but stepping up to a 40mm bore provides 739N both ways. The double-rod architecture is chosen over a single-rod SAI when the load needs anti-rotation guidance, a rear cam, or a secondary tool mount. Note that a plain SAID does not hold position without live air pressure; for locking needs, consider the SAIL or BSAID variants.
At 400mm of stroke, the 12mm rod experiences bending moments under side loads. To prevent premature rod-bearing wear, use an external guide rail to support the load. Because the rod protrudes from the rear cover, ensure you have adequate clearance for the secondary rod end.
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 SAID32X400 FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It provides 345N at 0.5 MPa, 483N at 0.7 MPa, and 621N at 0.9 MPa for both extend and retract strokes.
Yes, it is dimensionally interchangeable with ISO 15552 profile cylinders. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, but does not use the FB, CA, CB, or CR brackets found on single-rod versions.
