About the Airtac SAID32 Double Rod Cylinder SAID32AX270
The AirTAC SAID32X270 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 270mm stroke. Because the piston rod extends from both end covers, the annulus area is identical on both sides. This means the cylinder generates exactly 483N of force in both extend and retract directions at 0.7 MPa.
This specific configuration features SUS420J2 stainless steel rods for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount position switches along the stroke. Note that the rear rod protrudes outward, so you must account for this additional clearance when designing your machine layout.

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 SAID32AX270 Is Used
Symmetric Force Transfer
Drives a workpiece back and forth with identical 483N force and speed in both directions, ensuring perfectly balanced dual-station actuation.
Anti-Rotation Slides
The twin-rod design keeps the load guided and prevents rotational twist without requiring external guide rods, ideal for precision handling.
Rear-Rod Cam Actuation
Mount the primary tool on the front rod and use the rear rod end to drive a secondary cam or mechanism, maximizing machine layout efficiency.
Is the Airtac SAID32 Double Rod Cylinder SAID32AX270 the Right Cylinder?
Choose this 32mm bore double-rod cylinder when an application requires equal push and pull forces, alongside dual-side guidance to prevent rotation. If you need less force, stepping down is not an option in this size, but stepping up to a 40mm bore yields 739N both ways at 0.7 MPa. Because this 270mm stroke exceeds 300mm? No, but it is getting long; for any stroke approaching 300mm or more, ensure you use an external guide to prevent rod-bearing bending under side loads.
This SAID32X270 is dimensionally interchangeable per ISO 15552 standards. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Remember that a plain double-rod cylinder does not hold its load when air pressure is lost; if position holding is required, consider the SAIL or BSAID series. Specify the -S option if you need a magnet for CMSE reed or DMSE electronic sensors.

- ✓ 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 SAID32AX270 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It delivers 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 SAID32X270 is dimensionally interchangeable with other ISO 15552 profile cylinders. It uses the standard ISO 15552 mounting interface and accepts Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
