About the Airtac SAID200 Double Rod Cylinder SAID200BX55S
The AirTAC SAID200X55-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetric actuation. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 15079 N of force in each direction at 0.5 MPa. The SUS304 stainless steel rods provide excellent corrosion resistance, while the integrated magnet enables precise position tracking.
This through-rod architecture allows you to mount the primary workpiece on the front rod and a mechanical cam, limit flag, or secondary mechanism on the rear. Operating at 0.15-1.0 MPa with adjustable air cushions at both ends, it ensures smooth deceleration. The extruded aluminum barrel features sensor grooves on both sides for flexible CMSE or DMSE switch mounting.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX55S Is Used
Symmetric Pressing
Delivers 15079 N of equal force on both extend and retract strokes, ideal for heavy-duty pressing and forming operations requiring consistent bidirectional pressure.
Twin-Station Transfer
Drives two separate mechanisms simultaneously by mounting tooling on the front rod end and a secondary actuator or flag on the rear protruding rod.
Anti-Rotation Guiding
The dual-rod configuration provides superior resistance to torsional deflection, keeping heavy loads perfectly aligned during short-stroke positioning.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX55S the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when your application demands massive equal bidirectional force and high anti-rotation stability. If you need less force, stepping down to the 160 mm bore drops the both-way output to 9425 N at 0.5 MPa. Choosing the double-rod SAID over a single-rod SAI ensures twin-side guidance and allows rear-rod sensing. As a standard 55 mm stroke, it avoids the side-load and rod-bearing bending risks that plague longer unsupported strokes.
For a drop-in replacement, match the 200 mm bore, 55 mm stroke, PT tapered port threads, and the required mounting accessory from the SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are single-rod SAI only. Remember that the adjustable air cushions only decelerate the piston; they do not hold the load. If air pressure is lost, the cylinder will drift. For position holding without live pressure, consider an external rod lock or the BSAID clamp-lock variant.

- ✓ 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 SAID200BX55S FAQ
Because it is a double-rod cylinder, the force is identical in both directions due to equal annulus areas. It provides 15079 N both ways at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
Yes, the SAID200X55-S is dimensionally interchangeable per ISO 15552. It shares the exact mounting interface and footprint of other standard ISO 15552 double-rod profile cylinders, allowing for a direct drop-in replacement.
