This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X800, 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 SI200X800
The AirTAC Airtac SI200 Standard Cylinder SI200X800 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 800mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X800, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X800
The AirTAC SI200X800 is a discontinued double-acting ISO 15552 profile cylinder with an 800 mm stroke, delivering 15708 N push force at 0.5 MPa through its G3/4 port. The direct replacement is the SAI200X800, matching the exact bore, stroke, force, port and ISO 15552 mounting interface.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This non-magnet SKU cannot take a sensor, and the 800 mm stroke requires external guides to prevent rod bending.

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 SI200X800 Is Used
Heavy Press Stamping
Drives large metal forming presses requiring 15708 N push force at 0.5 MPa to shape thick steel plates.
Large Mold Transfer
Shifts substantial injection molds over the 800 mm travel distance, relying on external guides to prevent rod bending.
Replacing the Airtac SI200 Standard Cylinder SI200X800 with the SAI200X800
To replace the SI200X800, order the SAI200X800 and confirm the ISO 15552 mounting interface, M36x2 rod thread, G3/4 port, and 50 mm cushions. Because this non-magnet SKU lacks a sensor groove switch slot, it cannot use CS1-B/DS1-B sensors. For load holding, note that a plain cylinder drifts on air loss; use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 800 mm stroke, add external guides to prevent rod bending. If sizing down, the 160 mm bore offers 10053 N push at 0.5 MPa; if sizing up, no larger standard bore exists.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X800
- ✓ 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 SI200X800 FAQ
Yes, the SI200X800 is discontinued. The direct replacement is the SAI200X800, matching the same ISO 15552 mounting interface, 200 mm bore, 800 mm stroke, force, G3/4 port, and accessories.
At 0.5 MPa it pushes 15708 N and pulls 15080 N. At 0.7 MPa push is 21991 N, and at 0.9 MPa it is 28274 N. The theoretical max force is 3204 kgf at 1.0 MPa, with a speed range of 30-500 mm/s.
