About the Airtac SAID32 Double Rod Cylinder SAID32X250S
The AirTAC SAID32X250-S is a double-acting, double-rod profile cylinder conforming to ISO 15552 standards. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 483 N of force in both directions at 0.7 MPa. The -S suffix indicates an integrated magnet compatible with AirTAC CMSE reed and DMSE solid-state switches, fitting neatly into the dual sensor grooves on the aluminum barrel.
This 32mm bore unit features a 12mm carbon steel rod with M10x1.25 threading and PT tapered port connections. The twin-rod architecture allows operators to mount a primary workpiece on the front and a position flag or cam on the rear protruding rod, providing superior anti-rotation guidance for 250mm travel.

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 SAID32X250S Is Used
Symmetric Transfer
Push and pull identical loads at matching speeds using the equal annulus area, ensuring perfectly synchronized transfer across a 250mm stroke.
Anti-Rotation Slide
Leverage the twin-rod guidance to prevent mechanical twisting and keep precision slides perfectly aligned during full extension.
Rear-Cam Actuation
Drive the primary tool on the front rod while using the rear protrusion to trip an external mechanical limit switch or cam.
Is the Airtac SAID32 Double Rod Cylinder SAID32X250S the Right Cylinder?
Select this 32mm bore model when your application requires symmetric force and speed both ways, stepping down from a 40mm bore (528N at 0.5MPa) if your load strictly demands 345N at 0.5MPa. Unlike a single-rod SAI, the double-rod SAID is chosen specifically for dual-side actuation or rear-rod sensing. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles found on single-rod variants.
Because this model has a 250mm stroke, it falls under the 300mm threshold, but the 12mm rod still requires attention to side-load limits. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load if air pressure is lost. For position holding without live pressure, consider an external pilot-operated check valve or the SAIL/BSAID locking variants.
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 SAID32X250S FAQ
It provides equal force in both extend and retract directions due to the double-rod design. It delivers 345N at 0.5MPa, 483N at 0.7MPa, and 621N at 0.9MPa.
Yes, it is dimensionally interchangeable per ISO 15552 profile cylinder standards. You can drop it in for other ISO 15552 double-rod units, ensuring your PT ports and mounting accessories match.
