About the Airtac SAID200 Double Rod Cylinder SAID200BX230
The AirTAC SAID200X230 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 230 mm stroke. Because a stainless steel rod exits both end covers, the effective piston area is identical on extend and retract, yielding an equal 15079 N output force at 0.5 MPa in either direction. The SUS304 rod material provides excellent corrosion resistance for harsh environments.
This design allows mounting a primary workpiece on one end and a cam, position flag, or secondary mechanism on the rear rod. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. It uses a PT tapered port thread and offers adjustable air cushioning at both ends to decelerate the heavy 200 mm piston smoothly.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX230 Is Used
Symmetric Force Transfer
Drives heavy transfer shuttles requiring identical push and pull forces, leveraging the 15079 N both-way capacity at 0.5 MPa without force asymmetry.
Anti-Rotation Slides
Guides wide heavy loads using the twin rods exiting both covers to prevent mechanical binding and maintain precise linear tracking without twisting.
Dual-Side Tooling
Mounts a primary clamp on the front rod and a rear position flag on the opposite end to trigger external proximity sensors during the stroke.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX230 the Right Cylinder?
Choose this 200 mm bore when an application demands high bidirectional force, as the equal 15079 N output at 0.5 MPa easily outclasses the 9425 N rating of the neighboring 160 mm bore. The twin-rod architecture is selected over a single-rod SAI when precise anti-rotation guidance or dual-side actuation is required. Since the stroke is 230 mm, the unsupported load length is moderate, but external guides are recommended for heavy tooling.
Remember that the adjustable air cushions only decelerate motion near stroke end; they do not hold the load. If the air supply drops, the piston will drift, so a SAIL or BSAID lock variant is needed for fail-safe position holding. This cylinder is dimensionally interchangeable per ISO 15552 and uses the reduced SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAID200BX230 FAQ
The SAID200X230 provides an equal force of 15079 N at 0.5 MPa in both extend and retract directions. Because the rod occupies both sides of the piston, the effective area is identical each way, reaching up to 27141 N at 0.9 MPa.
No, the standard SAID200X230 does not hold its position without live pressure. The adjustable air cushions only decelerate the piston near stroke end; for fail-safe load holding, consider a SAIL or BSAID clamp-lock variant.
