This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX230S, 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 SI200BX230S
The AirTAC SI200 Standard Cylinder SI200BX230S 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 SAI200BX230S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX230S
The AirTAC SI200BX230S 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 through a G3/4 port. The direct replacement is the SAI200BX230S, which matches the original ISO 15552 mounting interface, M36x2 thread, and 50 mm cushions. The SAI uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure. This -S model has a piston magnet for CS1-B/DS1-B sensors, and the -B rod is SUS304 stainless steel.
The SAI family adds SAIL and BSAI lock variants absent in the SI line. Note that a plain cylinder drifts on air loss; cushions only decelerate. For high heat, Viton H seals raise the temperature 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 SI200BX230S Is Used
Heavy Press Forming
Drives large stamping and forming presses requiring 15708 N of thrust at 0.5 MPa, utilizing the 230 mm stroke to seat heavy tooling.
Mold Clamping Systems
Secures large injection molds using the SUS304 stainless rod option, ensuring corrosion resistance in humid production environments.
Replacing the Airtac SI200 Standard Cylinder SI200BX230S with the SAI200BX230S
To replace the SI200BX230S, order the SAI200BX230S. It is dimensionally interchangeable per ISO 15552, retaining the exact 200 mm bore, 230 mm stroke, G3/4 port, and mounting fixtures. Confirm your port thread (PT/G/NPT) and mounting accessory. Because this -S SKU has a magnet, it accepts CS1-B/DS1-B sensors, though the SAI uses current AirTAC switches. The -B rod is SUS304 stainless steel. If you need more force, the neighboring bores step up output, but at 0.5 MPa this bore pushes 15708 N and pulls 15080 N. For stroke lengths at or over 300 mm, support the load to prevent rod bending and side-load wear. A plain cylinder does not hold load without live air; the 50 mm cushions only decelerate. For load holding, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX230S
- ✓ 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 SI200BX230S FAQ
Yes, the SI200BX230S is discontinued. The direct replacement is the SAI200BX230S. It is dimensionally interchangeable per ISO 15552, matching the 200 mm bore, 230 mm stroke, G3/4 port, and mounting interface.
The bore is 200 mm with a G3/4 port. At 0.5 MPa it pushes 15708 N and pulls 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.
