This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X380S, 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 SI200X380S
The AirTAC SI200 Standard Cylinder SI200X380S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 380mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X380S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X380S
The AirTAC SI200X380S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 380mm stroke. Delivering 15708N push force at 0.5MPa, it is replaced by the SAI200X380S. This direct successor retains the exact G3/4 port, M36x2 thread, and mounting interface, fitting existing fixtures seamlessly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. The -S magnet works with CS1-B/DS1-B sensors.

Where the Airtac SI200 Standard Cylinder SI200X380S Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 15708N push force at 0.5MPa with robust 40mm rod stability.
Large Mold Actuation
Actuates substantial industrial molds on production lines, utilizing the 380mm stroke for deep draw operations.
Replacing the Airtac SI200 Standard Cylinder SI200X380S with the SAI200X380S
To replace the SI200X380S, order the SAI200X380S. Verify the ISO 15552 mounting interface, 380mm stroke, G3/4 port (PT/G/NPT thread), and your specific mounting accessory. The built-in magnet (-S) accepts CS1-B/DS1-B switches, though the SAI uses current AirTAC sensors. Sizing both ways: this 200mm bore yields 15708N push at 0.5MPa; a neighbouring 160mm bore yields 10053N. For a 380mm stroke, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X380S
- ✓ 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 SI200X380S FAQ
Yes, the SI200X380S is discontinued. The direct replacement is the SAI200X380S. It is dimensionally interchangeable per ISO 15552, retaining the same 200mm bore, 380mm stroke, output force, G3/4 port, and mounting interface.
The G3/4 port feeds a 40mm rod. Forces are: 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, 28274N push at 0.9MPa, and a theoretical max of 3204kgf at 1.0MPa. Speed is 30-500mm/s.
