This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX190, 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 SI200BX190
The AirTAC Airtac SI200 Standard Cylinder SI200BX190 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 190mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX190, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX190
The AirTAC SI200BX190 is a discontinued double-acting ISO 15552 profile cylinder. Delivering 15708 N push force at 0.5 MPa through a 200 mm bore and 190 mm stroke, it is superseded by the SAI200BX190 direct replacement. The SAI matches the exact ISO 15552 mounting interface, G3/4 port, M36x2 rod thread and 50 mm cushions, fitting existing fixtures perfectly.
This SKU features a SUS304 stainless rod (option B) for corrosion resistance but lacks a magnet, so it cannot accept CS1-B/DS1-B sensors. The SAI upgrade introduces a two-piece Y-shaped piston seal for low start-up pressure.

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 SI200BX190 Is Used
Heavy Press Stamping
Drives large stamping presses requiring massive thrust, utilizing the 21991 N push force at 0.7 MPa to form thick steel plates.
Large Mold Clamping
Secures heavy industrial molds on injection machinery, relying on the robust 40 mm piston rod and 50 mm adjustable cushions.
Replacing the Airtac SI200 Standard Cylinder SI200BX190 with the SAI200BX190
To replace the SI200BX190, order the SAI200BX190. Verify the ISO 15552 mounting interface, 200 mm bore, 190 mm stroke, G3/4 port, and SUS304 rod. Since this non-magnetic SKU cannot hold a position switch, sensing is impossible. If dropping down to a 160 mm bore is considered, note it provides 10053 N push at 0.5 MPa. For load holding on air loss, the cushion only decelerates; you must add an external pilot check valve, rod lock, or use the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX190
- ✓ 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 SI200BX190 FAQ
Yes, the SI200BX190 is discontinued. The direct replacement is the SAI200BX190. It shares the identical ISO 15552 mounting interface, 200 mm bore, 190 mm stroke, output force, and G3/4 port, dropping straight into existing fixtures.
It features a G3/4 air port. The force ratings are: 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N push at 0.9 MPa, and a theoretical maximum of 3204 kgf at 1.0 MPa.
