About the Airtac SAID200 Double Rod Cylinder SAID200X400
The AirTAC SAID200X400 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 400 mm stroke. Because the piston rod extends from both end covers, the annulus area is identical on both sides, yielding a balanced 15079 N force at 0.5 MPa on both extend and retract strokes. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This twin-rod configuration is ideal for applications requiring dual-side guidance and anti-rotation. You can mount the primary workpiece on one rod end and attach a position flag, cam, or secondary mechanism to the rear. The carbon steel rod and M36x2 thread provide a robust interface, while adjustable air cushions at both ends manage deceleration over the 400 mm travel.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |

| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID200 Double Rod Cylinder SAID200X400 Is Used
Heavy-Duty Pressing
Delivers 15079 N of equal force in both directions for high-tonnage pressing and forming tasks.
Symmetric Transfer
Drives a dual-sided workpiece transfer system where equal push and pull speeds prevent load skewing.
Anti-Rotation Guides
Uses the twin-rod structure to keep heavy loads perfectly guided and prevent rotation during travel.
Is the Airtac SAID200 Double Rod Cylinder SAID200X400 the Right Cylinder?
Select this 200 mm bore model when an application demands massive symmetric force, as it generates 15079 N in both directions at 0.5 MPa. If you need slightly less force, stepping down to a 160 mm bore yields 9425 N each way. The double-rod design is chosen over a single-rod SAI when precise anti-rotation or rear-rod actuation is required. For this 400 mm stroke, which exceeds the 300 mm threshold, the long unsupported rod length increases the risk of side-load and rod-bearing bending, so utilizing an external guide is highly recommended.
This cylinder is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 double-rod cylinders. It uses a PT tapered G3/4 port and supports mounting accessories from the SAID set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that a plain SAID does not hold its load when air is lost; for position holding without live pressure, consider an AirTAC SAIL or BSAID clamp-lock 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 SAID200X400 FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides. 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.
Yes, the SAID200X400 is dimensionally interchangeable per ISO 15552 and can serve as a direct replacement for other ISO 15552 double-rod cylinders, using its G3/4 PT ports and standard mounting set.
