This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX230, 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 SI200AX230
The AirTAC SI200 Standard Cylinder SI200AX230 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 230mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX230, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX230
The AirTAC SI200AX230 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 230 mm stroke. It delivers 15708 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI200AX230, matching the interface, bore, stroke, force, and mounting exactly.
This SKU features a SUS420J2 stainless steel rod and no magnet, meaning it cannot accept a sensor. The SAI upgrade uses two Y-shaped piston seals for low start-up pressure. For load holding, note the cushion only decelerates; use an external rod lock or SAIL/BSAI variant.

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 SAI200AX230 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 SI200AX230 Is Used
Heavy Press Forming
Generates 21991 N at 0.7 MPa for stamping and forming thick metal plates in automated fabrication lines.
Pallet Positioning
Shifts loaded industrial pallets horizontally, utilizing the 15080 N pull force to index heavy materials.
Replacing the Airtac SI200 Standard Cylinder SI200AX230 with the SAI200AX230
To replace the SI200AX230, order the SAI200AX230 direct. Confirm the ISO 15552 mounting interface, 200 mm bore, 230 mm stroke, G3/4 port, and SUS420J2 rod. Since this SKU lacks a magnet, it cannot support switches; add -S if sensing is needed. At 0.5 MPa it pushes 15708 N and pulls 15080 N (max 3204 kgf at 1.0 MPa). Neighbouring bores: 160 mm gives 10053 N push, 125 mm gives 6136 N. For load holding on air loss, the cushion only decelerates; use an external pilot check valve or the SAIL/BSAI lock variant. For 230 mm strokes, guide rods prevent side-load bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX230
- ✓ 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 SI200AX230 FAQ
Yes, the SI200AX230 is discontinued. The direct replacement is the SAI200AX230. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 230 mm stroke, 15708 N force, G3/4 port, and mounting interface.
It features a G3/4 port. Force ratings are: 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.
