This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X100FA, 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 SI200X100FA
The AirTAC Airtac SI200 Standard Cylinder SI200X100FA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X100FA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X100FA
The AirTAC SI200X100FA is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 100mm stroke. Built for heavy-duty tasks, it delivers 15708 N of push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI200X100FA. This current-production direct maintains the exact ISO 15552 mounting interface, bore, stroke, output force, and FA flange accessory, fitting existing fixtures perfectly.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements, ensuring low start-up pressure and extended lifespan. Note that this specific SKU lacks a magnet (-S), so it cannot accept CS1-B or DS1-B sensors. If high-temperature operation is needed, Viton H seals raise the limit to 150 C.

Where the Airtac SI200 Standard Cylinder SI200X100FA Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring 15708 N of thrust at 0.5 MPa, utilizing the 200mm bore for massive impact force.
Large Mold Handling
Positions heavy injection molds and industrial tooling within manufacturing cells, relying on the rigid FA flange mounting interface.
Replacing the Airtac SI200 Standard Cylinder SI200X100FA with the SAI200X100FA
To replace the discontinued SI200X100FA, order the SAI200X100FA. Verify the ISO 15552 FA flange interface, 200mm bore, 100mm stroke, and G3/4 port (available in PT, G, or NPT threads). Because this SKU has no magnet, it cannot support position sensing; if switches are required, select an SAI equivalent with the S suffix. When sizing, the 200mm bore yields 15708 N push at 0.5 MPa; dropping to a 160mm bore reduces this to 10053 N. Remember, a standard cylinder does not hold load without live air—the cushion only decelerates. For load holding on air loss, use an external pilot check valve or explore the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X100FA
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
