About the Airtac SAID200 Double Rod Cylinder SAID200BX20
The AirTAC SAID200X20 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 20 mm stroke. Because a stainless steel SUS304 rod exits both end covers, the annulus area is identical on extend and retract. This yields an equal push and pull force of 15079 N at 0.5 MPa, ensuring perfectly symmetric motion control.
This through-rod design allows mounting a primary workpiece on the front and a position flag, cam, or secondary mechanism on the rear rod. The extruded aluminum barrel includes sensor grooves on both sides, while the PT tapered G3/4 port ensures a robust pneumatic connection for heavy-duty industrial tasks.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX20 Is Used
Heavy-Duty Symmetric Pressing
Utilizes the equal 15079 N extend and retract force at 0.5 MPa to drive high-tonnage pressing and forming operations with consistent bidirectional power.
Anti-Rotation Transfer Unit
Leverages the double-rod design to move heavy pallets or fixtures without rotational drift, keeping loads perfectly guided across the stroke.
Dual-Side Tool Actuation
Mounts a primary forming tool on the front rod end and a secondary cam or position flag on the rear protruding rod to synchronize two linked mechanisms.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX20 the Right Cylinder?
Choose this 200 mm bore when an application requires massive bidirectional force that a smaller bore cannot provide, such as shifting 15079 N loads at just 0.5 MPa. The twin-rod architecture is selected over a single-rod SAI when strict anti-rotation guidance or dual-side actuation is mandatory. Note that a plain SAID does not hold its load if air pressure is lost; for fail-safe holding, consider an external rod lock or the BSAID clamp-lock variant.
Although the 20 mm stroke is very short, the 40 mm rod diameter provides excellent rigidity against side loads. Ensure your mounting accessory matches the SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2) as FB, CA, CB, and CR brackets are exclusive to single-rod SAI cylinders. This cylinder is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAID200BX20 FAQ
It provides an equal force of 15079 N in both extend and retract directions at 0.5 MPa, and 21110 N at 0.7 MPa, because the rod area is subtracted from both sides of the piston.
Yes, the SAID200X20 is dimensionally interchangeable per ISO 15552, acting as a drop-in replacement for other standard profile double-rod cylinders.
