This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X480S, 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 SI200X480S
The AirTAC SI200 Standard Cylinder SI200X480S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 480mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X480S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X480S
The AirTAC SI200X480S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 480mm stroke. Delivering 15708 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI200X480S. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, 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. The SI -S magnet supports legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL and BSAI lock variants absent in the SI line.

Where the Airtac SI200 Standard Cylinder SI200X480S Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring 15708 N of push force at 0.5 MPa to shape thick metal components.
Automated Assembly Lines
Shifts heavy machinery modules and large fabricated structures along production tracks using the 480mm stroke length.
Replacing the Airtac SI200 Standard Cylinder SI200X480S with the SAI200X480S
To replace the SI200X480S, order the SAI200X480S. Verify the ISO 15552 mounting interface (LB, FA, CA, TC), the G3/4 port, and the -S magnet for current AirTAC switches. At 0.5 MPa it yields 15708 N push; sizing down, the 160mm bore gives 10053 N. A 480mm stroke requires external guides to prevent rod bending under side loads. The air cushion only decelerates; for load holding on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X480S
- ✓ 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 SI200X480S FAQ
Yes, the SI200X480S is discontinued. The direct replacement is the SAI200X480S. It is dimensionally interchangeable per ISO 15552, retaining the same 200mm bore, 480mm stroke, output force, G3/4 port, and mounting interface.
It 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, with a 50mm adjustable air cushion at both ends.
