This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X100SFA, 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 SI200X100SFA
The AirTAC Airtac SI200 Standard Cylinder SI200X100SFA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X100SFA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X100SFA
The AirTAC SI200X100SFA is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 100mm stroke. Built for heavy-duty tasks, it delivers 15708 N of push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAI200X100SFA, a direct upgrade sharing the exact ISO 15552 mounting interface, FA flange, G3/4 port, and output force.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. This unit includes a piston magnet for legacy CS1-B/DS1-B sensors, and Viton H seal options raise operating temps to 150 C.

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 SAI200X100SFA 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 SI200X100SFA Is Used
Heavy Stamping Press
Drives large metal forming dies requiring up to 21991 N of push force at 0.7 MPa, utilizing the robust 40mm piston rod.
Industrial Clamp Fixture
Secures massive fabricated steel components during machining, applying safe holding forces around 9425 N.
Pallet Lowering Unit
Manages vertical descent of 800 kg material loads with controlled air cushions and FA flange mounting.
Replacing the Airtac SI200 Standard Cylinder SI200X100SFA with the SAI200X100SFA
To replace the discontinued SI200X100SFA, order the SAI200X100SFA. Verify your ISO 15552 FA flange interface, 200mm bore, 100mm stroke, G3/4 port, and the -S magnet for CS1-B/DS1-B switches. If you need to size down, the 160mm bore yields 10053 N at 0.5 MPa; sizing up is not available as 200mm is the maximum. Note that a standard cylinder drifts without live air—the cushion only decelerates. For load holding, use an external pilot check valve or explore the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X100SFA
- ✓ 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 SI200X100SFA FAQ
Yes, the SI200X100SFA is discontinued. The direct replacement is the SAI200X100SFA. It shares the same ISO 15552 profile interface, 200mm bore, 100mm stroke, G3/4 port, and FA mounting, so it fits existing fixtures directly.
At 0.5 MPa, the push force is 15708 N and pull is 15080 N. At 0.7 MPa it pushes 21991 N, and 28274 N at 0.9 MPa. The theoretical max force is 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s, and it uses a G3/4 air port.
