This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X900FA, 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 SI200X900FA
The AirTAC Airtac SI200 Standard Cylinder SI200X900FA 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 SAI200X900FA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X900FA
The AirTAC SI200X900FA is a discontinued double-acting ISO 15552 profile cylinder. Delivering 15708 N push force at 0.5 MPa through a 200 mm bore, it is replaced by the SAI200X900FA. This direct successor matches the 900 mm stroke, G3/4 port, M36x2 rod thread and FA flange mounting, fitting existing fixtures seamlessly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Because this specific SKU lacks the -S magnet, it cannot accept a CS1-B/DS1-B sensor. The family also adds SAIL lock and BSAI clamp-lock variants absent in the SI line.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |

Where the Airtac SI200 Standard Cylinder SI200X900FA Is Used
Heavy Stamp Press
Drives large tonnage metal forming presses where the 28274 N push force at 0.9 MPa and 900 mm travel accommodate deep drawing operations.
Pallet Hoist Gate
Actuates heavy industrial freight elevator gates, utilising the 801 kg vertical lift capacity to raise solid steel barriers safely.
Mould Clamping Arm
Secures large injection mould halves along the 900 mm stroke, requiring external guides to prevent rod bending during alignment.
Replacing the Airtac SI200 Standard Cylinder SI200X900FA with the SAI200X900FA
To replace the SI200X900FA, order the SAI200X900FA. Verify the ISO 15552 FA flange interface, 200 mm bore, 900 mm stroke, G3/4 port (PT/G/NPT thread) and non-magnet configuration. Sizing both ways: a neighbouring 160 mm bore yields 10053 N push at 0.5 MPa, while stepping up is unnecessary as this bore already hits 21991 N at 0.7 MPa. At 900 mm, add external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss; the 50 mm cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. Viton H seals raise heat resistance to 150 C.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X900FA
- ✓ 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 SI200X900FA FAQ
Yes, the AirTAC SI200X900FA is discontinued. The direct replacement is the SAI200X900FA. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 900 mm stroke, output force, G3/4 port and FA flange mounting.
The 200 mm bore features a G3/4 port and M36x2 rod thread. Force output is 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and a theoretical maximum of 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
