About the Airtac SAID100 Double Rod Cylinder SAID100X270
The AirTAC SAID100X270 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 270mm stroke. Because a carbon steel rod exits both ends, the effective piston area is identical in both directions, yielding an equal extend and retract force of 3681 N at 0.5 MPa. This symmetric design is ideal for mechanisms requiring consistent power and speed throughout the cycle.
A major advantage of this twin-rod layout is the ability to mount a primary workpiece on the front rod end while attaching a position flag, cam, or secondary mechanism to the rear rod. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. It uses a G1/2 PT port and omits the FB, CA, CB, and CR mounts, utilizing a reduced accessory set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAID100 Double Rod Cylinder SAID100X270 Is Used
Symmetric Force Transfer
Drives heavy push-and-pull machinery where equal force and velocity are critical, preventing cycle timing mismatches caused by standard single-rod area differences.
Anti-Rotation Slides
Guides heavy machining slides using both rod ends to resist torsional twist and maintain precise perpendicularity during heavy milling or clamping operations.
Dual-Station Actuation
Actuates a primary workpiece on the front stroke while the rear rod simultaneously triggers a mechanical valve or secondary mechanism on the opposite side.
Is the Airtac SAID100 Double Rod Cylinder SAID100X270 the Right Cylinder?
Choose this 100mm bore when an application demands high symmetric thrust—stepping down to a 63mm bore yields 1402 N each way, while this SAID100X270 provides 3681 N at 0.5 MPa. The double-rod architecture is selected over a single-rod SAI when the load requires dual-side guidance to prevent rotation, or when a rear rod is needed to drive a secondary station. Since the 270mm stroke exceeds 250mm, the 25mm rod and thread face increased bending moments; always use an external guide to support the load and minimize side-load wear on the rod bearing.
This cylinder is dimensionally interchangeable per ISO 15552, acting as a drop-in replacement for other ISO 15552 double-rod cylinders. It operates without a magnet, so position sensing requires external methods or a custom build. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load. If the mechanism must maintain position without live air pressure, consider an external rod lock or a SAIL cylinder.

- ✓ 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 SAID100X270 FAQ
Because the double-rod design subtracts the rod area on both sides, the push and pull forces are equal. It delivers 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa in both directions.
Yes, the SAID100X270 is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 double-rod cylinders. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and a G1/2 PT port.
