About the Airtac SAID100 Double Rod Cylinder SAID100X290S
The AirTAC SAID100X290-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a through-rod that exits both end covers. Because the piston rod occupies both sides, the effective annulus area is identical in each direction, yielding an equal extend and retract force of 3681 N at 0.5 MPa. This symmetric force capability is ideal for mechanisms requiring consistent power and speed regardless of travel direction.
Equipped with a standard magnet (-S), this unit supports AirTAC CMSE reed and DMSE solid-state electronic sensors mounted directly into the dual-side extruded barrel grooves. The carbon steel rod provides robust load transmission, while the PT G1/2 porting ensures high airflow for rapid cycling. A rear rod extension can drive a secondary mechanism or position flag, delivering superior anti-rotation guidance compared to a single-rod SAI.

Where the Airtac SAID100 Double Rod Cylinder SAID100X290S Is Used
Symmetric Force Transfer
Drives heavy workpieces back and forth with exactly matched push and pull forces, preventing speed variations in automated machining lines.
Anti-Rotation Slides
Uses the twin-rod geometry to rigidly guide vertical lifting slides and prevent mechanical binding under asymmetric load distributions.
Through-Rod Sensing
Mounts a CMSE or DMSE position switch on the rear rod extension to independently verify end-of-stroke without interfering with the primary work area.
Is the Airtac SAID100 Double Rod Cylinder SAID100X290S the Right Cylinder?
Selecting this 100mm bore is optimal when your application demands high bidirectional force (up to 6626 N at 0.9 MPa) but stepping up to the 160mm bore (9425 N at 0.5 MPa) would be excessive overkill. Conversely, smaller bores like the 80mm (2268 N at 0.5 MPa) may lack the required thrust for heavy symmetric transfer. The double-rod design is specifically chosen over a single-rod SAI when you need twin-station actuation, dual-side guidance to prevent load rotation, or rear-rod position sensing.
This model uses PT G1/2 tapered ports and a 25mm carbon steel rod with an M20x1.5 thread. It is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders. Mounting options include the SAID-specific set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB/CA/CB/CR). Because the stroke is 290mm, the longer unsupported rod is susceptible to bending under side-loads; always use an external guide rail to protect the rod bearing. Note that the adjustable air cushion only decelerates the piston near stroke end and does not hold the load if air pressure is lost.
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 SAID100X290S FAQ
Because the rod exits both ends, the effective piston area is identical in both directions. It delivers an equal push and pull force of 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa.
It is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other standard profile double-rod cylinders. However, it does not hold its load when air is lost; for position holding you need a SAIL lock, BSAID clamp-lock, or an external rod lock.
