This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X160N, 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 SI80X160N
The AirTAC SI80 Standard Air Cylinder SI80X160N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X160N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X160N
The AirTAC SI80X160N is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 160mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa via a G3/8 port. The direct replacement is the SAI80X160N, matching the interface, force, and mounting.
This NBR-sealed (-N) unit operates from -20 to +70C. Because this SKU lacks the -S magnet, it cannot accept CS1-B/DS1-B sensors. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure, and adds SAIL, SAIF, 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 SI80X160N Is Used
Mid-Tonnage Pressing
Applies 2513N of thrust at 0.5MPa for seating bearings or light stamping tasks within a 160mm travel.
Package Diversion
Drives heavy-duty routing gates or pushers on high-throughput material handling lines.
Pallet Lift Stops
Acts as a robust physical stop or lifting lug for palletized goods, safely handling ~128kg vertical loads.
Replacing the Airtac SI80 Standard Air Cylinder SI80X160N with the SAI80X160N
To replace the SI80X160N, order the SAI80X160N: it drops into existing ISO 15552 fixtures with the same 80mm bore, 160mm stroke, G3/8 port, M20x1.5 rod thread, and 36mm cushions. This non-magnetic SKU cannot take a sensor; if position feedback is needed, select an SAI80X160NS. Sizing both ways: an 80mm bore yields 2513N push at 0.5MPa (max 513kgf at 1.0MPa); dropping to a 63mm bore gives 1559N, while a 100mm bore gives 3927N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding. The SAIL or BSAI lock variants are ideal if you need integrated holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X160N
- ✓ 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 SI80X160N FAQ
Yes, the SI80X160N is discontinued. The direct replacement is the SAI80X160N. It shares the identical ISO 15552 mounting interface, 80mm bore, 160mm stroke, output force, and G3/8 port, fitting existing fixtures perfectly.
The G3/8 port feeds a 25mm rod delivering 2513N push and 2268N pull at 0.5MPa. At 0.7MPa push is 3518N, and 4523N at 0.9MPa. The theoretical maximum force is 513kgf at 1.0MPa.
