This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X80, 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 SI200X80
The AirTAC Airtac SI200 Standard Cylinder SI200X80 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X80, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X80
The AirTAC SI200X80 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm stroke, delivering 15708 N push force at 0.5 MPa. The direct replacement is the SAI200X80, matching the bore, port, and ISO 15552 mounting interface.
This SKU lacks a magnet and cannot take a sensor. The SAI upgrade uses two Y-shaped piston seals for low start-up pressure.

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 SI200X80 Is Used
Heavy Press Tonnage
Generates up to 21991 N at 0.7 MPa for high-force stamping, forming, and riveting operations in metal fabrication lines.
Industrial Clamp Systems
Secures large fabricated steel structures or molds during machining, utilizing the 3204 kgf maximum theoretical force at 1.0 MPa.
Replacing the Airtac SI200 Standard Cylinder SI200X80 with the SAI200X80
To replace the SI200X80, order the SAI200X80 and verify the ISO 15552 interface, G3/4 port, and M36x2 rod thread. Because this non-magnet SKU cannot accept a CS1-B/DS1-B sensor, add external sensing if needed. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variant. If upsizing, the 160 mm bore offers 10053 N at 0.5 MPa; downsizing drops to 80 mm at 2513 N.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X80
- ✓ 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 SI200X80 FAQ
Yes, the AirTAC SI200X80 is discontinued. The direct replacement is the SAI200X80, which shares the exact ISO 15552 mounting interface, 200 mm bore, 80 mm stroke, and G3/4 port.
It features a G3/4 port and delivers 15708 N push / 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and a maximum theoretical force of 3204 kgf at 1.0 MPa.
