This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X800SH, 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 SI200X800SH
The AirTAC SI200 Standard Cylinder SI200X800SH 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 SAI200X800SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X800SH
The AirTAC SI200X800SH is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 800 mm stroke. Designed for heavy-duty tasks, it delivers 15708 N of push force at 0.5 MPa. The direct replacement is the SAI200X800SH, matching the bore, stroke, 3204 kgf max force, G3/4 port, and ISO 15552 mounting interface. The SAI features an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life.
This legacy unit includes a piston magnet for CS1-B/DS1-B switches and a Viton H seal for 0-150 C high-temperature environments. Note that the standard air cushions only decelerate the load near stroke end; they do not hold position on air loss.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAI200X800SH produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI200 Standard Cylinder SI200X800SH Is Used
Heavy Stamping Press
Drives large heavy-duty stamping and forming dies requiring up to 28274 N of thrust at 0.9 MPa within high-temperature environments.
Aluminum Extrusion
Handles hot billet shears and large material handling gates in aluminum extrusion plants, leveraging the 0-150 C Viton H seal.
Replacing the Airtac SI200 Standard Cylinder SI200X800SH with the SAI200X800SH
To replace the SI200X800SH, order the SAI200X800SH. Verify the ISO 15552 mounting interface, 800 mm stroke, G3/4 port, and Viton H high-temp seal. If you need to downsize, a 160 mm bore yields 10053 N push at 0.5 MPa; upsizing is not available above 200 mm. For this 800 mm stroke, use an external guide to prevent rod bending and side-load damage. The plain cylinder drifts without live air, so for load holding use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants. The magnet (-S) works with legacy CS1-B/DS1-B sensors; the SAI uses current AirTAC switches.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X800SH
- ✓ 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 SI200X800SH FAQ
Yes, the SI200X800SH is discontinued. The direct replacement is the SAI200X800SH. It is dimensionally interchangeable per ISO 15552, offering the same 200 mm bore, 800 mm stroke, G3/4 port, and mounting interface, but adds an upgraded piston seal.
It uses a G3/4 air port. The thrust outputs are: 15708 N push and 15080 N pull at 0.5 MPa; 21991 N push at 0.7 MPa; 28274 N push at 0.9 MPa; and a theoretical maximum force of 3204 kgf at 1.0 MPa.
