About the Airtac SAID32 Double Rod Cylinder SAID32X40
The AirTAC SAID32X40 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 40mm stroke. Because a 12mm rod exits both ends of the piston, the annular area is identical on extend and retract, yielding exactly 483N of force in each direction at 0.7 MPa. The standard carbon steel rod provides durable service for general pneumatic tasks.
This design allows you to mount the primary workpiece on one end and a position flag or cam on the rear rod end. The extruded aluminum barrel includes sensor grooves on both sides, and the adjustable air cushions at both ends absorb end-of-stroke impact. Note that without a magnet (-S suffix), it will not trigger CMSE or DMSE reed or electronic sensors.

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 SAID32X40 Is Used
Symmetric Transfer
Handles push-pull transfer tasks where equal 483N force and speed in both directions keep the motion cycle perfectly balanced.
Anti-Rotation Slide
The twin 12mm rods keep the load guided against rotation better than a single rod, ideal for precision sliding fixtures.
Rear Cam Actuation
Mount the primary tool on the front rod and use the rear rod end to drive a secondary mechanism or trigger a mechanical limit flag.
Is the Airtac SAID32 Double Rod Cylinder SAID32X40 the Right Cylinder?
Choose this 32mm bore when your application requires equal push and pull forces, which differs from a single-rod SAI cylinder that has a higher extend force. If your mechanism needs less force, dropping down means losing the 483N capability; stepping up to a 40mm bore provides 528N at 0.5 MPa. The PT tapered port thread matches standard pneumatic fittings.
Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles found on single-rod variants. Remember that the adjustable cushions only decelerate the piston near stroke end; they do not lock the load. If air pressure drops, the cylinder drifts, so use an external rod lock or pilot-operated check valve for position holding. Dimensionally interchangeable per ISO 15552, it serves as a direct replacement for other ISO 15552 double-rod cylinders.
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 SAID32X40 FAQ
It provides 345N at 0.5 MPa, 483N at 0.7 MPa, and 621N at 0.9 MPa. Because it is a double-rod cylinder, this pull-side force figure is identical for both the extend and retract directions.
Yes, it is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 double-rod cylinders by matching the 32mm bore, 40mm stroke, and PT port.
