About the Airtac SAID40 Double Rod Cylinder SAID40X110
The AirTAC SAID40X110 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 110mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 528 N of force in each direction at 0.5 MPa. This symmetric output is perfect for twin-station actuation where both strokes must do equal work.
The twin-rod architecture provides superior anti-rotation stability compared to a single-rod SAI. You can mount the primary workpiece on the front rod and use the rear protrusion to carry a position flag for CMSE or DMSE sensors. The extruded aluminum barrel includes sensor grooves on both sides, and fluid must be filtered to 40 um.

Where the Airtac SAID40 Double Rod Cylinder SAID40X110 Is Used
Twin-Station Actuation
Drives two separate mechanisms simultaneously with identical 528 N force and speed, ensuring perfectly synchronized motion across dual workstations.
Anti-Rotation Slides
The dual carbon steel rods prevent piston rotation during travel, providing the precise linear guidance required for machining or assembly slides.
Through-Rod Sensing
Mounts the primary tool on the front rod while the rear rod end carries a position flag for CMSE or DMSE sensors, saving footprint.
Is the Airtac SAID40 Double Rod Cylinder SAID40X110 the Right Cylinder?
Choose this 40mm bore when an application requires 528 N of symmetric thrust both ways at 0.5 MPa. If your payload is lighter, step down to the 32mm bore (345 N); if heavier, step up to the 50mm bore (825 N). The double-rod design is selected over a single-rod cylinder when you need dual-side guidance, rear-rod sensing, or to drive two mechanisms in tandem.
This model uses PT tapered port threads (G1/4) and supports the reduced SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2 (omitting FB, CA, CB, CR). It is dimensionally interchangeable per ISO 15552. Note that the variable air cushion only decelerates the piston near stroke end; it does not hold the load. If position holding without live pressure is required, use a SAIL lock, BSAID clamp-lock, or external pilot-operated check valve.
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 SAID40 Double Rod Cylinder SAID40X110 FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It provides 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID40X110 is dimensionally interchangeable per ISO 15552. It shares the standard mounting interface and can serve as a drop-in replacement for other ISO 15552 double-rod profile cylinders.
