About the Airtac SAID32 Double Rod Cylinder SAID32AX20S
The AirTAC SAID32X20-S is a double-acting, double-rod ISO 15552 profile cylinder. Because a rod exits both ends, the annulus area is identical on both sides, yielding an equal extend and retract force of 345 N at 0.5 MPa. It is dimensionally interchangeable with other ISO 15552 double-rod cylinders.
This variant includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, while the rear rod end provides an excellent mounting point for a position flag or secondary cam.

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 SAID32AX20S Is Used
Symmetric Force Transfer
Drives small clamps or stops where equal push and pull momentum is required, ensuring consistent cycle timing without unequal force spikes.
Rear-Cam Actuation
Uses the protruding rear rod to trigger a mechanical limit switch or operate a secondary valve, saving space on the main actuation side.
Anti-Rotation Slides
Guides light pallets or trays in a dual-rail setup, using the twin rods to resist torsional twist during horizontal indexing.
Is the Airtac SAID32 Double Rod Cylinder SAID32AX20S the Right Cylinder?
Choose this 32mm bore over the larger 40mm bore (which provides 528 N each way) when your compact transfer mechanisms require lower symmetric force and strict space constraints. The twin-rod design is preferred over a single-rod SAI when a application demands anti-rotation guidance or requires driving a secondary mechanism from the rear rod. Remember that a plain SAID cylinder does not hold its load if air pressure drops; for fail-safe holding, consider an external rod lock or the SAIL series.
With a 20mm stroke, side-load stress on the rod bearing is minimal, but always confirm the exact overall length matches your frame. This unit uses PT tapered port threads (G1/8) and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting the FB, CA, CB, and CR options found on single-rod variants.
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 SAID32AX20S FAQ
Because the double-rod design subtracts the rod area on both sides, the output force is equal in both directions. It provides 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa.
Yes, the SAID32X20-S is dimensionally interchangeable per ISO 15552 mounting interface standards. It uses a profile barrel design and supports standard mounts like FA, LB, and TC.
