This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X286S, 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 SI200X286S
The AirTAC SI200 Standard Cylinder SI200X286S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 286mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X286S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X286S
The AirTAC SI200X286S is a discontinued double-acting ISO 15552 profile cylinder. Delivering 15708 N push force at 0.5 MPa through a 200 mm bore, it features a 286 mm stroke, a G3/4 air port, and a 40 mm carbon steel rod. The direct replacement is the SAI200X286S, which preserves the original ISO 15552 mounting interface, output force, and port size for seamless fixture integration.
Upgrading to the SAI200X286S introduces a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also adds SAIL and BSAI lock variants absent from the SI line, while the original -S magnet supports CS1-B/DS1-B sensors.

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 SAI200X286S 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 SI200X286S Is Used
Heavy Stamp Pressing
Generates up to 28274 N at 0.9 MPa for forming thick metal plates and driving large stamping dies in automotive lines.
Large Mold Actuation
Shifts substantial injection mold cores or heavy clamping fixtures with a 50 mm adjustable air cushion decelerating the 40 mm rod.
Replacing the Airtac SI200 Standard Cylinder SI200X286S with the SAI200X286S
To replace the SI200X286S, order the SAI200X286S. Verify your existing ISO 15552 mounting hardware (LB, FA, TC, etc.), the G3/4 port threads, and the M36x2 rod-end connection. The -S suffix indicates a piston magnet for CS1-B/DS1-B switches; the SAI replacement uses current AirTAC sensors. For sizing, a neighboring 160 mm bore yields 10053 N push at 0.5 MPa, whereas stepping up is not required since this 200 mm bore provides 21991 N at 0.7 MPa. Because the 286 mm stroke exceeds 300 mm guidelines, ensure adequate guide support to prevent rod bending under side loads. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X286S
- ✓ 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 SI200X286S FAQ
Yes, the SI200X286S is discontinued. The direct replacement is the SAI200X286S. It is dimensionally interchangeable per ISO 15552, maintaining the same 200 mm bore, 286 mm stroke, G3/4 port, and mounting interface, so it drops directly into existing fixtures.
The G3/4 port feeds a 200 mm bore generating 15708 N push and 15080 N pull at 0.5 MPa. At 0.7 MPa push is 21991 N, and 28274 N at 0.9 MPa. The theoretical maximum force is 3204 kgf at 1.0 MPa.
