This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1600, 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 SI80X1600
The AirTAC SI80 Standard Air Cylinder SI80X1600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1600
The AirTAC SI80X1600 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 1600 mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa via a G3/8 port. Because 1600 mm exceeds the 1500 mm standard maximum, this is a non-standard, made-to-order length requiring external guides to prevent rod bending under side loads.
You must replace it with the direct replacement SAI80X1600, which retains the exact ISO 15552 mounting interface, bore, stroke, force and port. The SAI upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure and long life. Note this SKU lacks a magnet and cannot accept 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 | — |

Where the Airtac SI80 Standard Air Cylinder SI80X1600 Is Used
Long-Stroke Material Transfer
Pushes heavy pallets 1600 mm between conveyor lines using 2513 N of thrust at 0.5 MPa, requiring external guide rails to support the extended rod.
High-Bay Shuttle Extraction
Extracts totes from deep storage racks; the 80 mm bore provides 2268 N pull force, while the direct SAI replacement fits existing ISO 15552 fixtures.
Automated Assembly Ejection
Ejects completed assemblies from a 1600 mm long machining bed, operating at speeds up to 800 mm/s with adjustable 36 mm air cushions.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1600 with the SAI80X1600
To replace this SI with the SAI80X1600, verify your ISO 15552 mounting interface (LB, FA, TC, etc.), the G3/8 port, and the M20x1.5 rod thread. Size both ways: the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding, or specify the SAIL/BSAI lock variants. Since 1600 mm exceeds the 1500 mm standard stroke, it is made-to-order; always use external guides to manage rod-bending side loads on long strokes. This non-magnetic SKU cannot take a sensor.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1600
- ✓ 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 SI80X1600 FAQ
Yes, the SI80X1600 is discontinued. The direct replacement is the SAI80X1600. It is dimensionally interchangeable per ISO 15552, retaining the same 80 mm bore, 1600 mm stroke, 2513 N force, G3/8 port and mounting accessories.
The 80 mm bore uses a G3/8 port and features a 25 mm rod with an M20x1.5 thread. It delivers 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 maximum of 513 kgf at 1.0 MPa.
