This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1400STC, 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 SI80X1400STC
The AirTAC SI80 Standard Air Cylinder SI80X1400STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1400mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1400STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1400STC
The AirTAC SI80X1400STC is a discontinued double-acting ISO 15552 profile cylinder with a 1400 mm stroke and TC trunnion mount. Delivering 2513 N push force at 0.5 MPa, it features a Ø25 mm rod, M20x1.5 thread, G3/8 port and 36 mm cushions. The direct replacement is the SAI80X1400STC.
The SAI successor retains identical ISO 15552 mounting, bore, stroke, force and port, but adds an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure. The original -S magnet works with legacy CS1-B/DS1-B sensors.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAI80X1400STC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI80 Standard Air Cylinder SI80X1400STC Is Used
Long-Stroke Material Transfer
Drives large pallets across 1.4 m conveyor sections using the 2513 N push force at 0.5 MPa.
Automated Assembly Line Indexing
Shifts heavy subassemblies between stations via the TC trunnion mount and ISO 15552 interface.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1400STC with the SAI80X1400STC
To replace the SI80X1400STC, order the SAI80X1400STC. Verify the TC trunnion interface, 80 mm bore, 1400 mm stroke, G3/8 port (PT/G/NPT) and the -S magnet for CS1-B/DS1-B switches. For sizing, neighbouring bores are 63 mm (1559 N [email protected]) and 100 mm (3927 N). A plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 1400 mm, use an external guide to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1400STC
- ✓ 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 SI80X1400STC FAQ
Yes, the SI80X1400STC is discontinued. The direct replacement is the SAI80X1400STC. It shares the same ISO 15552 mounting interface, 80 mm bore, 1400 mm stroke, G3/8 port and output force, fitting existing fixtures directly.
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa push is 3518 N, and max theoretical force is 513 kgf at 1.0 MPa. Speed is 30-800 mm/s. It has a G3/8 port, M20x1.5 rod thread and 36 mm cushions.
