About the Airtac SAID32 Double Rod Cylinder SAID32AX275S
The AirTAC SAID32X275-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 275mm stroke. Because the piston rod extends from both end covers, the effective annulus area is identical on the extend and retract strokes, yielding perfectly symmetrical force and speed. This design delivers 345 N of thrust and pull force in either direction at 0.5 MPa.
Equipped with a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic sensors via the dual-side barrel grooves. The rod is constructed from SUS420J2 stainless steel (option A) for enhanced corrosion resistance, and fluid connections use PT tapered ports. A rear rod protrusion requires extra clearance in your layout, but provides a second mounting point for a cam, limit flag, or secondary mechanism.

| 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 SAID32AX275S Is Used
Symmetric Force Transfer
Drives a workpiece from one end while the opposing rear rod moves an identical secondary tool at the exact same speed and 345 N force.
Anti-Rotation Slides
The twin-rod architecture prevents piston twist during vertical lifting operations, ensuring precise linear guidance without external rails.
Through-Rod Sensing
Mounts a DMSE electronic sensor target on the rear protruding rod to independently confirm stroke completion at high cycling speeds.
Is the Airtac SAID32 Double Rod Cylinder SAID32AX275S the Right Cylinder?
Select this 32mm bore when an application demands equal push/pull dynamics, such as a symmetric transfer unit where the rear rod drives an external flag. If you need higher force, stepping up to the 40mm bore raises the both-way output to 528 N at 0.5 MPa. Conversely, if your space is highly constrained, you must verify if a smaller bore can handle the 345 N load. For this 275mm stroke, the 12mm rod and M10x1.25 thread carry moderate side loads, but an external guide bearing is strongly recommended to prevent rod bending over the extended travel.
As a double-rod variant, the SAID32X275-S provides superior anti-rotation stability compared to a single-rod SAI cylinder. It uses a reduced ISO 15552 mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Note that the adjustable air cushions only decelerate the piston near stroke ends; they do not hold a load. If air pressure drops, the cylinder will drift, requiring an external rod lock or a SAIL/BSAID variant for true position holding.
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 SAID32AX275S FAQ
Because it is a double-rod cylinder, the force is identical in both directions. It provides 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa for both extend and retract strokes.
Yes, it is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other standard ISO 15552 profile cylinders, provided your layout accommodates the rear rod protrusion and uses the PT G1/8 port.
