This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX200S, 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 SI200BX200S
The AirTAC SI200 Standard Cylinder SI200BX200S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX200S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX200S
The AirTAC SI200BX200S is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 200 mm stroke. Built for heavy-duty tasks, it delivers 15708 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI200BX200S, a direct upgrade sharing the exact ISO 15552 mounting interface, bore, stroke, output force, and accessories.
The SAI200BX200S features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This -S model includes a piston magnet for legacy CS1-B/DS1-B sensors, and the -B rod option specifies a SUS304 stainless piston rod for corrosion resistance.

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 SI200BX200S Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring high thrust, using the 15708 N push force at 0.5 MPa to form thick metal components reliably.
Large Mold Clamping
Secures oversized injection molds in place during production, relying on the 50 mm adjustable air cushions to decelerate the massive 200 mm bore payload.
Replacing the Airtac SI200 Standard Cylinder SI200BX200S with the SAI200BX200S
To replace the SI200BX200S, order the SAI200BX200S. Confirm the ISO 15552 mounting interface, 200 mm bore, 200 mm stroke, G3/4 port (PT/G/NPT thread), and your mounting accessory. The -S suffix means a magnet is present for CS1-B/DS1-B switches, while the -B indicates a SUS304 stainless rod. If sizing alternatives, neighbouring bores or checking the 21991 N push at 0.7 MPa can guide you. A plain cylinder drifts on air loss since the cushion only decelerates; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. For any stroke over 300 mm, add external guides to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX200S
- ✓ 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 SI200BX200S FAQ
Yes, the SI200BX200S is discontinued. The direct replacement is the SAI200BX200S. It shares the same ISO 15552 mounting interface, 200 mm bore, 200 mm stroke, output force, and G3/4 port, so it fits existing fixtures perfectly.
This double-acting cylinder delivers 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s, the rod thread is M36x2, and it uses a G3/4 air port.
