This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X900, 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 SI200X900
The AirTAC SI200 Standard Cylinder SI200X900 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X900, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X900
The AirTAC SI200X900 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 900 mm stroke. It delivers 15708 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI200X900, matching the interface, bore, stroke, force and mounting exactly.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This no-magnet SKU cannot take a sensor. For high heat, Viton H seals raise the limit to 150 C.

Where the Airtac SI200 Standard Cylinder SI200X900 Is Used
Heavy Press Actuation
Drives large industrial presses requiring 15708 N push at 0.5 MPa, utilizing the 900 mm stroke for deep draw operations.
Large Mold Transfer
Moves heavy injection molds between stations, where the 50 mm adjustable air cushions absorb kinetic energy at the 900 mm stroke ends.
Replacing the Airtac SI200 Standard Cylinder SI200X900 with the SAI200X900
To replace the SI200X900, order the SAI200X900. Confirm the ISO 15552 mounting interface (LB, FA, CA, TC), the 900 mm stroke, and the G3/4 port. This SKU lacks the -S magnet, so it cannot accept CS1-B/DS1-B sensors. If you need load holding on air loss, note that the cushion only decelerates; use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The 900 mm stroke demands an external guide to prevent rod bending. If downsizing, a 160 mm bore gives 10053 N push; if upsizing, you are at the maximum. Operating speed is 30-500 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X900
- ✓ 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 SI200X900 FAQ
Yes, the AirTAC SI200X900 is discontinued. The direct replacement is the SAI200X900. It is dimensionally interchangeable per ISO 15552, matching the 200 mm bore, 900 mm stroke, 15708 N force, G3/4 port, and mounting accessories.
The G3/4 port feeds a 40 mm rod. Forces 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 max of 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
