This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX190S, 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 SI200BX190S
The AirTAC SI200 Standard Cylinder SI200BX190S 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 SAI200BX190S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX190S
The AirTAC SI200BX190S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 190mm stroke. Delivering 15708 N push force at 0.5 MPa through a G3/4 port, it is replaced by the SAI200BX190S. This direct upgrade shares the exact ISO 15552 mounting interface, bore, and force, fitting existing fixtures perfectly.
The SAI 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 magnet for CS1-B/DS1-B switches, and the -B rod is SUS304 stainless steel. Note the cushion only decelerates; use SAIL or BSAI for load holding.

Where the Airtac SI200 Standard Cylinder SI200BX190S Is Used
Heavy Press Systems
Drives large stamping and forming presses requiring 15708 N push force at 0.5 MPa, utilizing the 190mm stroke for deep draw operations.
Large Mold Handling
Actuates heavy injection mold tooling or clamps large assemblies, relying on the G3/4 port for high-volume air flow and rapid response.
Replacing the Airtac SI200 Standard Cylinder SI200BX190S with the SAI200BX190S
To replace the SI200BX190S, order the SAI200BX190S. Confirm the ISO 15552 mounting interface, 200mm bore, 190mm stroke, G3/4 port, and SUS304 rod. The -S magnet works with legacy CS1-B/DS1-B sensors, though the SAI uses current AirTAC switches. For sizing, neighboring bores offer different forces: 160mm yields 10053 N [email protected], while 200mm provides 15708 N. A plain cylinder drifts without air; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. For any stroke >= 300mm, add external guides to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX190S
- ✓ 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 SI200BX190S FAQ
Yes, the SI200BX190S is discontinued. The direct replacement is the SAI200BX190S. It shares the same ISO 15552 mounting interface, 200mm bore, 190mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly without modifications.
The 200mm bore delivers 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 max of 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s, and the G3/4 port ensures adequate flow.
