This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X200, 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 SI80 Standard Air Cylinder SI80X200
The AirTAC SI80 Standard Air Cylinder SI80X200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X200
The AirTAC SI80X200 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 200 mm stroke. It delivers 2513 N push force at 0.5 MPa through a G3/8 port. AirTAC replaced this legacy unit with the SAI80X200, a direct sharing the same interface, bore, stroke, output force and mounting fixtures.
The SAI upgrade features a redesigned piston seal using two Y-shaped one-way elements for low start-up pressure and long life. For applications needing load holding, the SAI family introduces SAIL and BSAI lock variants absent in the SI line.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SI80 Standard Air Cylinder SI80X200 Is Used
Press Ejection
Provides the robust 2513 N output needed to positively eject formed metal parts from a heavy stamping die at 0.5 MPa operating pressure.
Pallet Diversion
Actuates a heavy-duty lane diverter arm to route loaded pallets, utilizing the 200 mm stroke to achieve full lane separation safely.
Vacuum Lifter Actuation
Raises and lowers a large vacuum gripper head for handling sheet materials, where the 80 mm bore supplies ample force to overcome tooling weight.
Replacing the Airtac SI80 Standard Air Cylinder SI80X200 with the SAI80X200
To replace the SI80X200, order the SAI80X200. Verify your ISO 15552 mounting interface (LB, FA, TC, etc.), the 200 mm stroke, and the G3/8 port. This SKU lacks the -S magnet, so it cannot accept a sensor; if position detection is needed, select a magnet-equipped SAI and use current AirTAC switches instead of the legacy CS1-B/DS1-B. If sizing up or down, consider the 63 mm bore (1559 N push @0.5 MPa) or the 100 mm bore (3927 N push @0.5 MPa). A plain cylinder drifts on air loss—the cushion only decelerates—so for suspended loads use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X200
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI80 Standard Air Cylinder SI80X200 FAQ
Yes, the AirTAC SI80X200 is discontinued. The direct replacement is the SAI80X200. It is dimensionally interchangeable per ISO 15552 mounting interfaces, matching the 80 mm bore, 200 mm stroke, output force, G3/8 port, and mounting accessories perfectly.
The bore uses a G3/8 air port. At 0.5 MPa it provides 2513 N push and 2268 pull force. At 0.7 MPa push is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
