About the Airtac SAID100 Double Rod Cylinder SAID100X290
The AirTAC SAID100X290 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 290mm stroke. Because a carbon steel rod extends from both end covers, the annulus piston area is identical on extend and retract, yielding exactly 3681 N of force in each direction at 0.5 MPa. This symmetric output is essential for mechanisms requiring identical push and pull dynamics.
Beyond equal bidirectional power, the rear rod protrusion allows engineers to mount a secondary cam, position flag, or separate tooling on the back side. The extruded aluminum barrel includes sensor grooves on both sides, ready for electronic DMSE or reed CMSE switches if a magnet is specified later. It operates at speeds of 30-800 mm/s.

Where the Airtac SAID100 Double Rod Cylinder SAID100X290 Is Used
Symmetric Transfer Unit
Drives a shuttle back and forth with equal 3681 N force both ways, ensuring consistent cycle times regardless of direction.
Anti-Rotation Slide
Uses the twin carbon steel rods exiting both ends to rigidly guide a heavy carriage and prevent mechanical twisting.
Dual-Station Actuation
Mounts the primary workpiece on the front rod end and a secondary cam or position flag on the rear to trigger operations.
Is the Airtac SAID100 Double Rod Cylinder SAID100X290 the Right Cylinder?
Choose this 100mm bore over the 80mm version (2268 N at 0.5 MPa) when your application demands higher bidirectional force, or step down to the 63mm bore (1402 N) if payload is lighter. A twin-rod design is selected over a single-rod SAI when the mechanism requires dual-side guidance to prevent rotation, or when a rear-facing position flag must trigger a sensor. Note that a plain SAID100X290 does not hold position if air pressure drops; use a SAIL or BSAID variant if fail-safe load locking is required.
With a 290mm stroke, the extended carbon steel rod can generate significant bending moments under side loads. For strokes of 300mm or more, adding an external linear guide is recommended to prevent rod-bearing wear. This cylinder uses a PT G1/2 port, accepts Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts (omitting FB and CA), and offers drop-in dimensional interchangeability with other ISO 15552 profile cylinders.
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 SAID100X290 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the extend and retract forces are equal. It provides 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa in both directions.
Yes, the SAID100X290 is dimensionally interchangeable per ISO 15552. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, though it omits the FB and CA mounts used on single-rod variants.
