About the Airtac SAID100 Double Rod Cylinder SAID100BX290S
The AirTAC SAID100X290-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 290mm stroke. Because the twin SUS304 stainless steel rods occupy both piston sides, the annulus area is identical in both directions. This yields an equal extend and retract force of 3681N at 0.5 MPa, meaning push and pull power are perfectly symmetric.
Equipped with a magnet for position sensing, the -S variant operates seamlessly with AirTAC CMSE reed and DMSE solid-state switches housed in the dual-side sensor grooves. Fluid ports are PT tapered G1/2 threads. The extruded aluminum barrel design makes it dimensionally interchangeable per ISO 15552, providing a drop-in replacement for other standard profile cylinders without relying on tie-rod construction.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX290S Is Used
Symmetric Transfer Units
Drives a transfer carriage with equal push and pull force, utilizing the twin rods to maintain precise alignment and prevent chassis rotation during high-speed indexing.
Twin-Station Actuation
Mounts the primary workpiece on the front rod and a secondary tooling head or limit flag on the rear rod, allowing one cylinder to sequence two separate operations simultaneously.
Anti-Rotation Slides
Guides heavy loads along a linear rail where the dual rigid rod ends prevent torsional twisting, maintaining strict perpendicularity during clamping or pressing tasks.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX290S the Right Cylinder?
Select this 100mm bore when an application requires substantial symmetric thrust—stepping down to an 80mm bore yields 2268N each way, while this model provides 3681N at 0.5 MPa. The double-rod architecture is chosen over a single-rod SAI when the mechanism demands dual-side guidance to prevent rotation, or when a rear rod end is needed to mount a secondary cam or position flag.
At a 290mm stroke, the unsupported load length increases bending moments on the rod bearings; utilize an external guide rail to handle side loads. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end and do not hold the load if air pressure is lost—use a SAIL or BSAID clamp-lock cylinder for fail-safe position holding. Replacement match: 100mm bore, 290mm stroke, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounts, with -S magnet.

- ✓ 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 SAID100BX290S FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It delivers an equal 3681N of force in both extend and retract directions at 0.5 MPa, and 5153N at 0.7 MPa.
Yes. As an extruded aluminum profile cylinder built to ISO 15552 mounting dimensions, it serves as a drop-in dimensional replacement for interchangeable ISO 15552 double-rod cylinders, utilizing PT G1/2 ports.
