This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X510, 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 SI200X510
The AirTAC SI200 Standard Cylinder SI200X510 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 510mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X510, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X510
The AirTAC SI200X510 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 510mm stroke. It delivers 15708N push force at 0.5MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI200X510. The SAI is a direct upgrade: identical ISO 15552 mounting interface, bore, stroke, force, port and accessories, fitting existing fixtures perfectly.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note this SKU lacks a magnet (-S) and cannot accept a CS1-B/DS1-B sensor. For high heat, Viton H seals raise the operating range to 150C.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |

Where the Airtac SI200 Standard Cylinder SI200X510 Is Used
Heavy Press Systems
Drives large stamping and forming presses requiring up to 15708N of thrust at 0.5MPa, utilizing the adjustable 50mm air cushions to absorb heavy impact at stroke ends.
Industrial Lift Gates
Actuates massive material lift gates and heavy-duty elevators. With a safe vertical lift capacity of roughly 801kg, it handles substantial loads reliably.
Large Mold Handling
Shifts heavy injection molds and tooling on production lines. The 510mm stroke allows long linear traverses, though external guides must be used to prevent rod bending.
Replacing the Airtac SI200 Standard Cylinder SI200X510 with the SAI200X510
To replace the SI200X510, order the SAI200X510. Verify your ISO 15552 mounting interface (LB, FA, CA, TC), the G3/4 port, and M36x2 rod thread. Because this is a non-magnet SKU, it cannot support position sensing; if you need switches, select an SAI200X510S and use current AirTAC sensors. At 0.5MPa, the 200mm bore yields 15708N push and 15080N pull; if undersizing, a 160mm bore provides 10053N. For the 510mm 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 variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X510
- ✓ 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 SI200X510 FAQ
Yes, the SI200X510 is discontinued. The direct replacement is the SAI200X510. It shares the exact same ISO 15552 mounting interface, 200mm bore, 510mm stroke, output force, G3/4 port, and accessories, fitting directly into your existing fixtures.
The 200mm bore features a G3/4 air port and an M36x2 rod thread. At 0.5MPa it provides 15708N push and 15080N pull force. At 0.7MPa push is 21991N, and at 0.9MPa it is 28274N. The theoretical maximum force is 3204kgf at 1.0MPa.
