This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X130N, 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 SI80X130N
The AirTAC SI80 Standard Air Cylinder SI80X130N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 130mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X130N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X130N
The AirTAC SI80X130N is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 130mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa through a G3/8 port. AirTAC replaced this legacy unit with the SAI80X130N, a direct upgrade sharing the exact ISO 15552 mounting interface, M20x1.5 rod thread, and 513kgf maximum force.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. This specific SKU lacks a magnet (-S) so it cannot accept CS1-B/DS1-B sensors, but the NBR (-N) seals handle -20 to +70C (Viton H extends this to 150C).

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 SI80X130N Is Used
Pallet Diversion
Pushes heavy pallets off a main conveyor line utilizing the 2513N thrust at 0.5MPa without stalling under friction.
Press Ejection
Ejects formed metal parts from a press die using the 130mm stroke and 2268N pull force to clear the tooling quickly.
Replacing the Airtac SI80 Standard Air Cylinder SI80X130N with the SAI80X130N
To replace the SI80X130N, order the SAI80X130N and verify your ISO 15552 mounting accessory (LB, FA, TC, etc.), G3/8 port thread (PT/G/NPT), and 130mm stroke. Because this SKU has no magnet, it cannot support position sensing; if you need switches, select an SAI80X130NS and use current AirTAC sensors. Sizing both ways: the 80mm bore gives 2513N push at 0.5MPa; if you need less force, a 63mm bore offers 1559N, while a 100mm bore provides 3927N. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding consider an external pilot check valve or the SAIL/BSAI lock variants. Since the 130mm stroke is under 300mm, rod bending is minimal, but always guide external loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X130N
- ✓ 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 SI80X130N FAQ
Yes, the AirTAC SI80X130N is end-of-life. The direct replacement is the SAI80X130N. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 80mm bore, 130mm stroke, G3/8 port, and 513kgf max force, but adds an upgraded Y-shaped piston seal for longer life.
The 80mm bore double-acting cylinder operates at 30-800mm/s. Force outputs are: 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a theoretical maximum of 513kgf at 1.0MPa. It features a 25mm rod, M20x1.5 thread, and 36mm adjustable cushions.
