This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX700S, 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 SI200BX700S
The AirTAC SI200 Standard Cylinder SI200BX700S 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 SAI200BX700S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX700S
The AirTAC SI200BX700S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 700mm stroke. Delivering 15708 N push force at 0.5 MPa through a G3/4 port, it is replaced by the SAI200BX700S. This direct successor shares the exact ISO 15552 mounting interface, M36x2 thread, and 50mm cushions, fitting existing fixtures perfectly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This -S variant has a magnet for CS1-B/DS1-B sensors, and the -B rod specifies SUS304 stainless steel. The SAI family also adds SAIL and BSAI lock variants absent in the SI line.

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 SI200BX700S Is Used
Heavy Press Stamping
Drives large press dies requiring 21991 N of thrust at 0.7 MPa to form thick metal components.
Mold Clamping Stations
Holds large injection molds in place via the ISO 15552 interface during heavy industrial operations.
Replacing the Airtac SI200 Standard Cylinder SI200BX700S with the SAI200BX700S
To replace the SI200BX700S, order the SAI200BX700S. Confirm the ISO 15552 mounting interface, 200mm bore, 700mm stroke, G3/4 port, and -S magnet for current AirTAC switches. When sizing, the 160mm bore offers 10053 N push at 0.5 MPa, while the 200mm bore hits 21991 N at 0.7 MPa. A plain cylinder drifts on air loss as cushions only decelerate; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. With a 700mm stroke, prevent rod bending by using external guides to manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX700S
- ✓ 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 SI200BX700S FAQ
Yes, the SI200BX700S is discontinued. The direct replacement is the SAI200BX700S. It is dimensionally interchangeable per ISO 15552, retaining the same 200mm bore, 700mm stroke, output force, G3/4 port, and mounting accessories.
At 0.5 MPa it pushes 15708 N and pulls 15080 N. Push force is 21991 N at 0.7 MPa and 28274 N at 0.9 MPa. The theoretical max is 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
