About the Airtac SAID200 Double Rod Cylinder SAID200X50S
The AirTAC SAID200X50-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 50 mm stroke. Because the twin carbon steel rods occupy both sides of the piston, the annulus area is identical in each direction, yielding exactly 15079 N of force both extending and retracting at 0.5 MPa. The integrated -S magnet pairs directly with AirTAC CMSE reed and DMSE solid-state switches mounted in the dual-side sensor grooves.
A defining advantage of this through-rod layout is the ability to drive a primary workpiece on one end while mounting a position flag, cam, or secondary mechanism on the rear rod. This architecture provides superior anti-rotation guidance for heavy loads compared to a single-rod SAI. The extruded aluminum barrel uses a PT tapered port thread, and the overall length is longer than a single-rod variant to accommodate the rear protrusion.

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 SAID200X50S Is Used
Heavy-Duty Pressing
Delivers 15079 N of equal force in both directions for high-tonnage pressing, forming, and stamping operations requiring stable, anti-rotation guidance.
Twin-Station Actuation
Drives two synchronized mechanisms simultaneously from one piston, using both rod ends to operate opposing stations with identical speed and force.
Rear-Rod Sensing
Mounts a position flag or cam on the rear rod to trigger AirTAC CMSE or DMSE sensors, keeping the primary front rod completely unobstructed for the workpiece.
Is the Airtac SAID200 Double Rod Cylinder SAID200X50S the Right Cylinder?
Select this 200 mm bore cylinder when an application demands massive bidirectional force (15079 N at 0.5 MPa, up to 27141 N at 0.9 MPa) with strict symmetrical speed. If you need less force, stepping down to the 160 mm bore yields 9425 N each way at 0.5 MPa. Choose the SAID double-rod configuration over the standard SAI when you need twin-station actuation, enhanced load guidance against rotation, or rear-rod sensing capabilities. It uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits the FB, CA, CB, and CR accessories found on single-rod variants.
This cylinder is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 double-rod cylinders. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If the machine loses air pressure, the piston will drift. For position holding without live pressure, use an external rod lock, a pilot-operated check valve, or switch to an AirTAC SAIL or BSAID clamp-lock model.

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 SAID200X50S FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides. It delivers 15079 N of force in both extend and retract directions at 0.5 MPa, and 27141 N at 0.9 MPa.
Yes, the SAID200X50-S is dimensionally interchangeable per ISO 15552. It serves as a direct replacement for other ISO 15552 double-rod cylinders, utilizing a PT port and standard mounting accessories like FA, LB, and TC.
