This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X460, 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 SI200X460
The AirTAC SI200 Standard Cylinder SI200X460 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 460mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X460, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X460
The AirTAC SI200X460 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 460mm stroke. Delivering 15708N push and 15080N pull at 0.5MPa, it uses a G3/4 port and M36x2 rod thread. The direct replacement is the SAI200X460, matching the exact ISO 15552 mounting interface, force, and dimensions.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This non-magnet SKU cannot take a sensor. For high temps, Viton H seals raise the range to 150C.

Where the Airtac SI200 Standard Cylinder SI200X460 Is Used
Heavy Stamp Press
Drives large heavy-duty stamping presses requiring 21991N push force at 0.7MPa to form thick metal plates.
Injection Molding
Actuates massive clamping fixtures on large-tonnage injection molding machines using its 28274N output at 0.9MPa.
Replacing the Airtac SI200 Standard Cylinder SI200X460 with the SAI200X460
To replace the SI200X460, order the SAI200X460, confirming the ISO 15552 mounting interface, 460mm stroke, and G3/4 port (PT/G/NPT). This non-S SKU lacks a magnet and cannot accept CS1-B/DS1-B sensors. For sizing down, a 160mm bore offers 10053N [email protected]; sizing up is not available. At 460mm stroke, use external guides to prevent rod bending and side loads. The 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 → SAI200X460
- ✓ 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 SI200X460 FAQ
Yes, the AirTAC SI200X460 is discontinued. The direct replacement is the SAI200X460. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 200mm bore, 460mm stroke, 15708N force, G3/4 port, and mounting accessories.
It features a G3/4 port. The force ratings 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. It operates at 30-500mm/s.
