About the Airtac SAID200 Double Rod Cylinder SAID200BX200
The AirTAC SAID200X200 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical actuation. Because the piston rod extends from both end covers, the annulus area is identical on both sides, yielding exactly 15079 N of force in both extend and retract directions at 0.5 MPa. This equal-force capability makes it ideal for applications requiring consistent push and pull dynamics.
This specific configuration features SUS304 stainless steel rods (code B) for superior corrosion resistance and utilizes PT tapered port threads. The rear rod protrusion allows designers to mount a secondary cam, position flag, or drive a second mechanism, while the extruded aluminum barrel includes dual-side sensor grooves for flexible switch placement.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX200 Is Used
Symmetric-Force Transfer
Drives heavy workpiece shuttles where the 15079 N push and pull forces must be perfectly equal to maintain consistent momentum in both directions.
Dual-Station Actuation
Uses the front rod to operate a primary press while the rear rod simultaneously triggers a secondary mechanism or mechanical flag.
Anti-Rotation Slides
Leverages the twin-rod geometry to guide heavy vertical loads against rotation without requiring external guide rails.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX200 the Right Cylinder?
Selecting the SAID200X200 is optimal when your mechanism requires massive bidirectional force that a single-rod SAI cannot provide symmetrically. If you need less force, stepping down to the 160mm bore offers 9425 N at 0.5 MPa, but the 200mm bore is necessary when pushing and pulling 15079 N simultaneously. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 double-rod cylinders, utilizing a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
Note that a plain SAID does not hold its position if air pressure is lost; the piston will drift without live pressure. For load-holding requirements, consider an external rod lock or the BSAID clamp-lock variant. Because this model lacks the -S magnet option, it cannot host AirTAC CMSE or DMSE sensors. For strokes of 200mm, side-load is moderate, but always ensure the load is guided externally to prevent rod-bearing bending.
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 SAID200BX200 FAQ
Because it is a double-rod cylinder, the force is identical in both directions. It provides 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID200X200 is dimensionally interchangeable per ISO 15552. It shares the standard mounting interface and utilizes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) for easy drop-in replacement.
