This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X75FA, 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 SI200X75FA
The AirTAC Airtac SI200 Standard Cylinder SI200X75FA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 75mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X75FA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X75FA
The AirTAC SI200X75FA is a discontinued double-acting ISO 15552 profile cylinder. Delivering 15708 N push at 0.5 MPa through a 200 mm bore, it is replaced by the SAI200X75FA. This direct successor shares the exact FA flange mount, 75 mm stroke, G3/4 port and M36x2 rod thread. The SAI upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure and long life. This non-magnet SKU cannot accept a sensor.
The SAI family also introduces SAIL and BSAI lock variants absent in the SI line. If your application requires high-temperature operation, Viton H seals raise the limit to 150 C.

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 SI200X75FA Is Used
Heavy Stamping
Drives large press dies requiring 15708 N push force at 0.5 MPa, utilizing the FA flange for rigid heavy-duty mounting.
Injection Molding
Actuates substantial mold halves and clamping fixtures where the 3204 kgf maximum theoretical force is essential.
Pallet Handling
Shifts heavy loaded pallets on conveyors, benefitting from the 801 kg safe vertical lift capacity and 50 mm cushions.
Replacing the Airtac SI200 Standard Cylinder SI200X75FA with the SAI200X75FA
To replace the SI200X75FA, order the SAI200X75FA. It drops directly into existing fixtures via the ISO 15552 FA flange interface, matching the 200 mm bore, 75 mm stroke and G3/4 port. Because this specific SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors; confirm if position detection is needed. When sizing, note a smaller 160 mm bore yields 10053 N push at 0.5 MPa, while the 200 mm bore provides 15708 N. A plain cylinder drifts on air loss; the 50 mm cushion only decelerates near stroke end. For load holding, specify an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X75FA
- ✓ 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 SI200X75FA FAQ
Yes, the SI200X75FA is discontinued. The direct replacement is the SAI200X75FA. It shares the identical ISO 15552 mounting interface, 200 mm bore, 75 mm stroke, output force, G3/4 port and FA flange, fitting existing fixtures perfectly.
It 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, 28274 N push at 0.9 MPa, and a maximum theoretical force of 3204 kgf at 1.0 MPa.
