About the Airtac SAID200 Double Rod Cylinder SAID200X350
The AirTAC SAID200X350 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical motion. Because a carbon steel rod exits both end covers, the effective piston area is identical on extend and retract, yielding an equal 15079 N of force in both directions at 0.5 MPa. This through-rod architecture provides superior anti-rotation guidance and allows a secondary mechanism or position flag to be mounted on the rear rod end.
Built with a standard PT tapered port thread (G3/4) and an extruded aluminum barrel featuring dual-side sensor grooves, it integrates seamlessly into existing ISO 15552 footprints. The adjustable air cushions at both ends deliver controlled deceleration for massive moving loads, while the carbon steel rod ensures high structural rigidity across the 350 mm stroke.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 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 SAID200X350 Is Used
Heavy-Duty Pressing
Provides a stable 15079 N clamping force in both directions for large metal forming and stamping presses.
Symmetric Transfer
Drives dual-station transfer arms where the rear rod end simultaneously actuates a secondary mechanism.
Anti-Rotation Slides
Keeps heavy guided loads perfectly aligned without twisting during 350 mm extend and retract cycles.
Is the Airtac SAID200 Double Rod Cylinder SAID200X350 the Right Cylinder?
Select this 200 mm bore model when an application requires immense equal bidirectional force and high torsional rigidity. If your push or pull requirements are lower, stepping down to the 160 mm bore yields 9425 N each way at 0.5 MPa, which may offer a more compact footprint. For this 350 mm stroke, the long unsupported rod length mandates an external guide to prevent rod-bearing bending under heavy side loads.
Choose the SAID double-rod configuration over a single-rod SAI when you need to drive twin stations, mount a rear cam, or prevent load rotation. Note that this cylinder does not hold its position when air pressure is lost; if dead-stop holding is required, consider the SAIL lock series or an external pilot-operated check valve. Replacement is straightforward via the ISO 15552 mounting interface using Basic, FA, LB, TC, FTC, TCM1, or TCM2 accessories.

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 SAID200X350 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the cylinder generates an equal force of 15079 N in both directions at 0.5 MPa, and up to 27141 N at 0.9 MPa.
Yes, the SAID200X350 is dimensionally interchangeable per ISO 15552 profile cylinder standards. It uses a standard G3/4 PT port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mountings for direct compatibility.
