About the Airtac SAID32 Double Rod Cylinder SAID32X125
The AirTAC SAID32X125 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 125mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding equal force and speed in both directions. This design outputs 345N each way at 0.5 MPa and 483N at 0.7 MPa.
Beyond balanced thrust, the twin-rod architecture allows you to mount a workpiece on the front thread (M10x1.25) and a position flag or cam on the rear. The extruded aluminum barrel includes sensor grooves on both sides, though adding a magnet (-S) is required if you plan to use AirTAC CMSE reed or DMSE electronic switches.

| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |

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 SAID32X125 Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where the 483N pull and push forces must be perfectly matched to maintain consistent cycle timing in both directions.
Anti-Rotation Slides
The twin-rod design keeps the load guided against rotation better than a single rod, making it ideal for lifting flat panels without a separate external guide.
Through-Rod Sensing
Mounts the primary tool on the front rod end while utilizing the rear protruding rod to physically trigger an external limit switch or carry a cam.
Is the Airtac SAID32 Double Rod Cylinder SAID32X125 the Right Cylinder?
Select this 32mm bore when an application demands 483N of symmetric force at 0.7 MPa, stepping down from a 40mm bore (528N at 0.5 MPa) if you do not need the extra push. Choose the SAID double-rod format over a single-rod SAI when you need dual-side guidance to prevent rotation or require rear-end sensing. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
This cylinder uses PT tapered G1/8 ports and operates at 30-800 mm/s. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If position holding without live air pressure is required, consider an external rod lock or the BSAID clamp-lock variant.
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 SAID32X125 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It delivers an equal force of 345N at 0.5 MPa, 483N at 0.7 MPa, and 621N at 0.9 MPa in both the extend and retract directions.
Yes, the SAID32X125 is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 double-rod profile cylinders, utilizing the standard mounting interface dimensions.
