This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X200FTC, 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 SI80X200FTC
The AirTAC SI80 Standard Air Cylinder SI80X200FTC 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 SAI80X200FTC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X200FTC
The AirTAC SI80X200FTC 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 via a G3/8 port. AirTAC replaced this unit with the SAI80X200FTC, a direct upgrade retaining the exact ISO 15552 mounting interface, FTC trunnion, and output force.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note this non-magnetic SKU cannot accept a sensor, unlike legacy CS1-B/DS1-B switches.

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 SI80X200FTC Is Used
Transfer Line Diversion
Uses the 200 mm stroke and 2513 N thrust to push heavy pallets onto parallel conveyor tracks without rebounding.
Pallet Stopper Gate
Leverages the FTC trunnion mount to handle side loads while acting as a robust 80 mm bore physical stop for inbound logistics.
Press Ejection
Provides reliable 2268 N pull force at 0.5 MPa to extract formed components from tight dies, aided by adjustable end cushions.
Replacing the Airtac SI80 Standard Air Cylinder SI80X200FTC with the SAI80X200FTC
To replace the SI80X200FTC, order the SAI80X200FTC. Confirm the ISO 15552 FTC trunnion mount, 80 mm bore, 200 mm stroke, and G3/8 port (PT/G/NPT thread options). This non-magnetic version cannot hold a position sensor; order an SAI80X200FTCS if switch tracking is required. For sizing, the 80 mm bore yields 2513 N push at 0.5 MPa; dropping to a 63 mm bore gives 1559 N, while an 80 mm at 0.7 MPa yields 3518 N. Because this is a plain cylinder, it will drift on air loss—the cushion only decelerates. For load holding, use an external pilot check valve, rod lock, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X200FTC
- ✓ 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 SI80X200FTC FAQ
Yes, the SI80X200FTC is discontinued. The direct replacement is the SAI80X200FTC. It matches the ISO 15552 mounting interface, 80 mm bore, 200 mm stroke, FTC trunnion, and G3/8 port, fitting existing fixtures perfectly.
The 80 mm bore uses a G3/8 port. It generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical max of 513 kgf at 1.0 MPa.
