About the Airtac SAID200 Double Rod Cylinder SAID200X75S
The AirTAC SAID200X75-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200mm bore and 75mm stroke. Because a carbon steel rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 15079 N of force each way at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides to accommodate CMSE reed and DMSE electronic switches.
This through-rod design allows you to mount the primary workpiece on one end and a cam, position flag, or secondary mechanism on the rear rod. It provides superior anti-rotation guidance compared to a single-rod SAI. The unit uses a PT tapered port and adjustable air cushions at both ends to decelerate the payload smoothly.

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 SAID200X75S Is Used
Symmetric Metal Forming
Provides 15079 N of equal push and pull force at 0.5 MPa for heavy stamping or press operations that require identical kinetic energy in both directions.
Anti-Rotation Guiding
The twin carbon steel rods prevent mechanical twisting on large indexing tables, ensuring precise linear movement without external guide rails.
Dual-Mechanism Drive
Mount the primary tool on the front rod end and a secondary position flag or cam on the rear protruding rod to actuate separate limit switches simultaneously.
Is the Airtac SAID200 Double Rod Cylinder SAID200X75S the Right Cylinder?
Choose this 200mm bore when an application requires massive symmetric force, as it generates 15079 N in both directions at 0.5 MPa. If you need less thrust, stepping down to a 160mm bore yields 9425 N each way. The twin-rod architecture is selected over a single-rod cylinder when dual-side guidance or rear-rod actuation is required to prevent load rotation.
For direct replacements, this model is dimensionally interchangeable per ISO 15552. Specify the 75mm stroke, G3/4 PT port, and the -S magnet for CMSE/DMSE sensors. Since the rear rod protrudes continuously, ensure you leave adequate clearance behind the rear cover. Remember that the adjustable cushions only decelerate the piston; they do not hold the load. If air pressure is lost, the cylinder will drift, requiring an external rod lock or a BSAID clamp-lock cylinder for secure positioning.

- ✓ 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 SAID200X75S FAQ
Because the rod occupies both sides of the piston, the effective area is equal for extend and retract. The SAID200X75-S generates 15079 N in both directions at 0.5 MPa, and 21110 N at 0.7 MPa.
Yes, the SAID200X75-S is dimensionally interchangeable per ISO 15552. It shares the standard mounting interface and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories, though it omits FB, CA, CB, and CR mounts.
