This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX700S, 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 SI200AX700S
The AirTAC SI200 Standard Cylinder SI200AX700S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 700mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX700S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX700S
The AirTAC SI200AX700S is a discontinued double-acting ISO 15552 profile cylinder featuring a 200mm bore, 700mm stroke, and a SUS420J2 stainless steel piston rod. It delivers 15708 N of push force at 0.5 MPa via its G3/4 port. AirTAC replaced this legacy unit with the SAI200AX700S, a direct upgrade retaining the exact mounting interface, bore, stroke, output force, and port size.
The SAI replacement upgrades longevity with two Y-shaped one-way piston seals for low start-up pressure, and introduces SAIL, SAIF, and BSAI lock variants absent in the SI line. The original -S magnet supports legacy CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches.

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 SI200AX700S Is Used
Heavy Press Forming
Generates 21991 N of thrust at 0.7 MPa, ideal for actuating large metal stamping or heavy-duty forming presses.
Mold Clamping Systems
Provides the 15708 N push force at 0.5 MPa required to secure large injection molds, with the -A stainless rod resisting plant humidity.
Replacing the Airtac SI200 Standard Cylinder SI200AX700S with the SAI200AX700S
To replace the SI200AX700S, order the SAI200AX700S. Verify your ISO 15552 mounting interface, 200mm bore, 700mm stroke, G3/4 port (PT/G/NPT), and the -S magnet for CS1-B/DS1-B switches. The SUS420J2 rod (-A) provides corrosion resistance versus standard carbon steel. If sizing alternatives, the 160mm bore yields 10053 N push at 0.5 MPa, while the 200mm bore hits 21991 N at 0.7 MPa. Note that a 700mm stroke requires external guides to prevent rod bending under side loads. For load holding on air loss, the cushion only decelerates; you must add an external rod lock, pilot check valve, or use the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX700S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
