About the Airtac SAID200 Double Rod Cylinder SAID200X25S
The AirTAC SAID200X25-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 25 mm stroke. Because the twin rods occupy both piston faces, the annulus area is identical in each direction, yielding an equal push and pull force of 15079 N at 0.5 MPa. A magnet is included for position sensing.
This unit uses standard carbon steel rods and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. Its short stroke makes it ideal for high-force clamping or pressing tasks where a rear rod can simultaneously drive a secondary mechanism or limit flag.

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 SAID200X25S Is Used
High-Force Symmetric Pressing
Delivers 15079 N of equal force in both directions, ideal for short-stroke pressing and stamping stations where the rear rod can simultaneously trigger a proximity flag.
Anti-Rotation Guiding
The twin 40 mm carbon steel rods prevent piston twist under heavy off-center loads, providing rigid dual-side guidance for precision tooling platforms.
Twin-Station Actuation
Drive two separate mechanisms from one cylinder by mounting a workpiece on the front rod end and a secondary cam or tool on the rear protruding rod end.
Is the Airtac SAID200 Double Rod Cylinder SAID200X25S the Right Cylinder?
Select this 200 mm bore model when an application requires immense equal bidirectional force (15079 N at 0.5 MPa) over a short 25 mm distance. If you need less force, step down to the 160 mm bore which provides 9425 N both ways. Choose this double-rod configuration over a single-rod SAI when you need dual-side guidance, anti-rotation stability, or a rear rod end to mount a secondary cam. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. Ensure you specify PT ports and the -S magnet for CMSE/DMSE sensor compatibility. Note that this cylinder does not hold loads without live air pressure; for holding requirements, consider the SAIL or BSAID series. The 25 mm stroke keeps the rod bearing stress minimal, avoiding the side-load bending risks seen in longer strokes.
Quick checklist
- ✓ 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 SAID200X25S FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides. It delivers an equal push and pull force of 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
Yes. The SAID200X25-S is an extruded aluminum profile cylinder built to ISO 15552 mounting dimensions, making it a direct replacement for other ISO 15552 double-rod cylinders. It uses a G3/4 PT port and includes a magnet for CMSE/DMSE sensors.
