About the Airtac SAID32 Double Rod Cylinder SAID32AX550
The AirTAC SAID32X550 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and a 550mm non-standard stroke. Because the piston rod exits both end covers, the annulus area is identical on both sides. This yields equal force and speed in both directions, providing 345N of thrust and pull at 0.5MPa. The twin-rod architecture also offers superior anti-rotation guidance compared to a single-rod SAI.
This unit is equipped with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Note that the 550mm stroke exceeds the standard 500mm maximum for this bore, making it a made-to-order item requiring extra rear-rod clearance.

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 SAID32AX550 Is Used
Twin-Station Actuation
Drive two separate mechanisms simultaneously from opposite rod ends, ensuring perfectly synchronized 550mm travel without needing a second cylinder.
Anti-Rotation Slides
The dual-rod geometry prevents piston rotation during transit, providing stable guidance for precision sliding fixtures over the extended stroke.
Through-Rod Sensing
Mount a cam or target flag on the protruding rear rod to trigger external sensors, verifying the exact mid-stroke or end-stroke position independently.
Is the Airtac SAID32 Double Rod Cylinder SAID32AX550 the Right Cylinder?
Select this non-standard 550mm stroke model when an application demands symmetric push/pull forces of 345N at 0.5MPa alongside extended travel. If your project requires less force, stepping down is not an option in the SAID series as 32mm is the minimum bore; however, stepping up to a SAID40X550 increases the both-way output to 528N. Choose the double-rod SAID over a single-rod SAI when you need to mount a secondary cam, position flag, or drive a second mechanism from the rear rod end.
As a dimensionally interchangeable ISO 15552 cylinder, it drops in seamlessly with other standard 32mm bore footprints. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the stroke is 550mm, the extended rod length increases the risk of side-load bending; an external guide bearing is recommended to support the load. Remember that the adjustable air cushions only decelerate the piston near stroke end and do not hold the load if air pressure is lost—use a SAIL lock or external pilot check valve for position holding.

- ✓ 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 SAID32AX550 FAQ
Because it is a double-rod cylinder, the force is identical in both extend and retract directions. It provides 345N at 0.5MPa, 483N at 0.7MPa, and 621N at 0.9MPa.
Yes. The SAID32X550 is dimensionally interchangeable per ISO 15552 and serves as a direct replacement for other standard 32mm double-rod profile cylinders, using PT port threads.
