This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX100S, 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 SI200AX100S
The AirTAC Airtac SI200 Standard Cylinder SI200AX100S 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 SAI200AX100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX100S
The AirTAC SI200AX100S is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 100 mm stroke. It delivers 15708 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI200AX100S, featuring the same interface, force, and mounting.
This SAI upgrade uses two Y-shaped one-way piston seals for low start-up pressure and long life. It retains the SUS420J2 stainless rod and CS1-B/DS1-B magnet compatibility.

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 SAI200AX100S 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 SI200AX100S Is Used
Heavy Press Systems
Drives large stamping and forming presses requiring up to 21991 N push force at 0.7 MPa.
Industrial Lift Gates
Actuates massive material handling gates and bulkhead doors with an 801 kg vertical lift capacity.
Large Mold Clamping
Secures heavy injection molds and fixtures using the robust 40 mm SUS420J2 stainless rod.
Replacing the Airtac SI200 Standard Cylinder SI200AX100S with the SAI200AX100S
To replace the SI200AX100S, order the SAI200AX100S. Verify the ISO 15552 mounting interface, 100 mm stroke, G3/4 port, and the -S magnet for legacy CS1-B/DS1-B sensors. The SUS420J2 stainless rod (-A) is retained. Sizing down, a 160 mm bore yields 10053 N push at 0.5 MPa; sizing up is not available. For load holding, note that a plain cylinder drifts on air loss as the cushion only decelerates. Use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX100S
- ✓ 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 SI200AX100S FAQ
Yes, the SI200AX100S is discontinued. The direct replacement is the SAI200AX100S. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 100 mm stroke, force, G3/4 port, and mounting accessories.
It features a G3/4 port. 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 theoretical max of 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
