About the Airtac SAID200 Double Rod Cylinder SAID200X450S
The AirTAC SAID200X450-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200mm bore and 450mm stroke. Because a carbon steel rod exits both end covers, the effective piston area is identical in both directions, yielding exactly 15079 N of force both extend and retract at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet enables precise position detection with AirTAC CMSE reed or DMSE solid-state switches.
This through-rod design allows you to mount a primary workpiece on one end while attaching a cam, secondary mechanism, or limit flag to the rear rod. The twin-rod architecture provides superior anti-rotation guidance compared to a single-rod SAI, while the adjustable air cushions at both ends absorb kinetic energy to prevent endcap impact.

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 SAID200X450S Is Used
Heavy Pressing & Forming
Delivers 21110 N of force at 0.7 MPa in both directions, ideal for heavy-duty pressing, bending, and forming operations requiring symmetric power.
Twin-Station Transfer
Drives two synchronized mechanisms simultaneously from a single actuator by utilizing the front and rear rod ends for dual-side workpiece transfer.
Anti-Rotation Lifts
The dual-rod construction prevents mechanical twisting and provides rigid vertical guidance for heavy lifting platforms without external linear bearings.
Is the Airtac SAID200 Double Rod Cylinder SAID200X450S the Right Cylinder?
Selecting this 200mm bore model is appropriate when your application requires massive bidirectional force, stepping up significantly from the 160mm bore which provides 9425 N at 0.5 MPa. A double-rod cylinder is chosen over a single-rod SAI when you need symmetric speed, equal push/pull power, or dual-side guidance to prevent mechanical binding under heavy loads. The PT threaded G3/4 port handles the necessary high airflow to maintain operational speeds within the 30-500 mm/s range.
Because the 450mm stroke is substantial, the unsupported rod length increases the risk of rod-bearing bending under side loads; utilizing an external guide rail is highly recommended. Remember that the adjustable air cushion only decelerates the piston near stroke end and does not hold the load if air pressure is lost—for positive holding, consider an external rod lock or a SAIL cylinder. This model is dimensionally interchangeable per ISO 15552 for direct replacement of other double-rod profile cylinders.

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 SAID200X450S FAQ
The double-rod design ensures equal force in both directions by using the annulus area on both sides. It delivers 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and up to 27141 N at 0.9 MPa.
