About the Airtac SAID100 Double Rod Cylinder SAID100AX300S
The AirTAC SAID100X300-S is a double-acting, double-rod profile cylinder fully dimensionally interchangeable per ISO 15552. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding an equal 3681 N of force each way at 0.5 MPa. This symmetric thrust is ideal for mechanisms requiring perfectly balanced push and pull dynamics.
This specific configuration features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and includes a magnet for position sensing. You can mount the primary workpiece on the front rod end and a cam or position flag on the rear, while dual-side sensor grooves accept AirTAC CMSE reed or DMSE solid-state switches.

Where the Airtac SAID100 Double Rod Cylinder SAID100AX300S Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where the 3681 N push and pull forces must be perfectly matched to prevent drive train backlash or uneven acceleration.
Twin-Station Actuation
Mounts a machining fixture on the front rod and a secondary cam on the rear rod to trigger a separate process at the exact same stroke interval.
Anti-Rotation Slides
Utilizes the through-rod design to guide heavy loads across a 300 mm stroke without the rotational twisting common to single-rod actuators.
Is the Airtac SAID100 Double Rod Cylinder SAID100AX300S the Right Cylinder?
Choose this 100 mm bore when a 80 mm bore (2268 N at 0.5 MPa) lacks the thrust for your symmetric transfer task, but you want to avoid the heavier 125 mm class. The double-rod design is selected over a single-rod SAI when the application demands dual-side guidance, anti-rotation stability, or rear-rod actuation. It uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and PT tapered ports.
At a 300 mm stroke, the unsupported rod length increases side-load risks and rod-bearing bending; always use an external guide to prevent premature wear. Note that a plain SAID does not hold its load when air is lost or the valve is centered—the piston drifts. For dead-air position holding, consider an external rod lock, SAIL, or BSAID clamp-lock variant.

- ✓ 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 SAID100 Double Rod Cylinder SAID100AX300S FAQ
It provides 3681 N of force at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. Because it is a double-rod cylinder, this force is identical in both extend and retract directions.
Yes, the SAID100X300-S is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod profile cylinders. It uses PT ports and works with AirTAC CMSE and DMSE sensors.
