Airtac SAID100 Double Rod Cylinder SAID100AX270S
The AirTAC Airtac SAID100 Double Rod Cylinder SAID100AX270S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 270mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAID100 Double Rod Cylinder SAID100AX270S
The AirTAC SAID100X270-S is a double-acting, double-rod ISO 15552 profile cylinder. A single piston drives a rod out of both end covers, yielding perfectly symmetric dynamics. Because the annulus area is identical on each side, it generates 3681 N of force in both extend and retract directions at 0.5 MPa.
This unit includes a magnet for CMSE reed and DMSE electronic sensors. The rod is SUS420J2 stainless steel for corrosion resistance, and the PT port threads ensure a robust tapered seal. The rear rod extension is ideal for mounting a position flag or driving a secondary mechanism while keeping the load guided against rotation.

Where the Airtac SAID100 Double Rod Cylinder SAID100AX270S Is Used
Symmetric Transfer
Drives a transfer carriage with equal speed and force in both directions, preventing stalling on the return stroke.
Anti-Rotation Slides
The twin rods exiting both ends keep the tool plate perfectly aligned, resisting torsional twist under offset loads.
Rear-Cam Actuation
Uses the protruding rear rod to trigger a mechanical limit switch or cam, leaving the front rod dedicated to the primary workpiece.
Is the Airtac SAID100 Double Rod Cylinder SAID100AX270S the Right Cylinder?
Select this 100 mm bore when an application requires matched push and pull forces that a single-rod SAI cannot provide. If your load needs less force, step down to the 80 mm bore (2268 N both ways); if you need more, the 125 mm bore offers 5734 N. Because the stroke is 270 mm, the extended rod length increases side-load bending leverage on the front bearing; for heavy radial loads, add an external guide rail.
This SAID model is dimensionally interchangeable per ISO 15552 as a drop-in replacement for other standard profile double-rod cylinders. It uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits the FB, CA, CB, and CR brackets found on single-rod variants. Note that the air cushions only decelerate the piston near stroke end; a plain SAID will drift and cannot hold a load if air pressure is lost. For dead-fail locking, consider a BSAID clamp-lock cylinder.
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 SAID100 Double Rod Cylinder SAID100AX270S FAQ
Because the rod occupies both sides of the piston, the effective area is equal in both directions. It delivers 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa for both extend and retract strokes.
Yes, it is dimensionally interchangeable with ISO 15552 profile cylinders. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, but omits the FB, CA, CB, and CR brackets which are specific to single-rod SAI cylinders.
