About the Airtac SAID200 Double Rod Cylinder SAID200BX290
The AirTAC SAID200X290 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical motion. Because a stainless SUS304 rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 15079 N of force both ways at 0.5 MPa. The twin-rod architecture is ideal for mounting a primary workpiece on one end and a position flag or cam on the rear protruding end.
This extruded aluminum barrel features dual-side sensor grooves for precise tracking. It uses adjustable air cushioning at both ends (50 mm cushion length) and operates at speeds of 30-500 mm/s. The PT G3/4 port ensures high flow, while the SUS304 rod provides excellent corrosion resistance for demanding environments.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX290 Is Used
Symmetric Force Transfer
Equal push and pull force makes this cylinder ideal for heavy presses and forming operations requiring identical force in both directions.
Twin-Station Actuation
Drive a primary mechanism on the front rod while simultaneously operating a secondary valve or clamp from the rear rod end.
Anti-Rotation Slides
The dual-rod construction prevents piston rotation, providing precise linear guidance for heavy tooling platforms without external guides.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX290 the Right Cylinder?
Choose this 200 mm bore when the 160 mm bore (9425 N at 0.5 MPa) is insufficient for your bidirectional load. The double-rod design is selected over a single-rod SAI when strict anti-rotation guidance or dual-side actuation is required. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
At 290 mm stroke, the long unsupported piston rod is susceptible to bending under side loads; utilize an external guide rail to protect the rod bearing. Note that a plain SAID does not hold its position when air pressure is lost—the air cushion only decelerates the piston near stroke end. For true load holding without live pressure, 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 SAID200 Double Rod Cylinder SAID200BX290 FAQ
Because the rod exits both sides, the effective piston area is equal in both directions. It provides 15079 N of force both ways at 0.5 MPa, and 21110 N at 0.7 MPa.
Yes, it is a profile cylinder built to ISO 15552 mounting dimensions, making it a drop-in replacement for other ISO 15552 double-rod cylinders. It uses a PT G3/4 port.
