This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X800S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI200 Standard Cylinder SI200X800S
The AirTAC SI200 Standard Cylinder SI200X800S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 800mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X800S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X800S
The AirTAC SI200X800S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 800mm stroke. Delivering 15708N push force at 0.5MPa via a G3/4 port, it is replaced by the SAI200X800S. This direct successor matches the interface, bore, stroke, force and mounting.
The SAI upgrade features two Y-shaped piston seals for low start-up pressure and longevity. The SI line lacked SAIL, SAIF and BSAI lock variants. This -S SKU uses CS1-B/DS1-B sensors.

Where the Airtac SI200 Standard Cylinder SI200X800S Is Used
Heavy Press Forming
Drives large stamping and forming tools using 15708N push force at 0.5MPa, relying on the 50mm adjustable cushions to absorb heavy impact at stroke ends.
Large Mold Handling
Actuates heavy industrial mold transfer carriages over 800mm distances, requiring external guide rails to prevent rod bending on the 40mm piston rod.
Replacing the Airtac SI200 Standard Cylinder SI200X800S with the SAI200X800S
To replace the SI200X800S, order the SAI200X800S. Verify the ISO 15552 mounting interface, 800mm stroke, G3/4 port (PT/G/NPT), M36x2 thread and the -S magnet for CS1-B/DS1-B switches. Sizing checks: a 160mm bore yields 10053N push at 0.5MPa, while a 200mm bore at 0.7MPa yields 21991N. For the 800mm stroke, use external guides to prevent rod bending and side-load damage. The cushion only decelerates; it does not hold load on air loss. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X800S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI200 Standard Cylinder SI200X800S FAQ
Yes, the SI200X800S is discontinued. The direct replacement is the SAI200X800S. It is dimensionally interchangeable per ISO 15552, keeping the same 200mm bore, 800mm stroke, 15708N force, G3/4 port and mounting fixtures.
This double-acting cylinder has a G3/4 port. Force ratings are: 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, 28274N push at 0.9MPa, and a theoretical max of 3204kgf at 1.0MPa.
