This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X900SH, 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 SI200X900SH
The AirTAC SI200 Standard Cylinder SI200X900SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X900SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X900SH
The AirTAC SI200X900SH is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 900 mm stroke. It delivers 15708 N of push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI200X900SH, which shares the exact ISO 15552 mounting interface, M36x2 rod thread, and 50 mm cushions.
The SAI upgrade features an improved piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This -S and -H configured legacy unit includes a piston magnet for CS1-B/DS1-B switches and a Viton H seal rated for 0-150 C. Note that a standard cylinder drifts without live air; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.

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 SAI200X900SH 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 SI200X900SH Is Used
Heavy Machinery Forming
Drives large presses and heavy forming fixtures requiring up to 21991 N of thrust at 0.7 MPa, utilizing the 200 mm bore for massive displacement.
Automated Pallet Lifting
Raises loaded pallets vertically, safely handling computed working loads near 9425 N with the 900 mm stroke providing extensive elevation range.
High-Temp Material Handling
Shifts heavy cast or hot components in foundry conveyors, leveraging the Viton H seal to operate reliably in ambient temperatures up to 150 C.
Replacing the Airtac SI200 Standard Cylinder SI200X900SH with the SAI200X900SH
To replace the SI200X900SH, order the SAI200X900SH. Verify your ISO 15552 mounting fixture, 200 mm bore, 900 mm stroke, G3/4 port, and M36x2 rod thread. The -S magnet enables current AirTAC switches (replacing legacy CS1-B/DS1-B), while the -H Viton seal handles 0-150 C environments. If you need more force, the neighboring bores are 160 mm and 125 mm; at 0.5 MPa they yield 10053 N and 6136 N respectively, compared to this bore's 15708 N. Because 900 mm exceeds 300 mm, use external guides to prevent rod bending and side-load damage. For dead-load holding, add a pilot check valve or external rod lock, as the SAI cushion only decelerates.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X900SH
- ✓ 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 SI200X900SH FAQ
Yes, the SI200X900SH is discontinued. The direct replacement is the SAI200X900SH. It is dimensionally interchangeable per ISO 15552, matching the 200 mm bore, 900 mm stroke, G3/4 port, and mounting interface, but adds an upgraded two Y-shaped element piston seal.
The 200 mm bore uses a G3/4 port. It generates 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 max force of 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
