This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X530, 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 SI80X530
The AirTAC SI80 Standard Air Cylinder SI80X530 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 530mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X530, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X530
The AirTAC SI80X530 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 530 mm stroke, delivering a 2513 N push force at 0.5 MPa through a G3/8 port. AirTAC replaced this legacy unit with the SAI80X530, a direct replacement sharing the exact ISO 15552 mounting interface, M20x1.5 rod thread, and 36 mm cushions.
The SAI upgrade features a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. For applications needing load holding on air loss, the SAI family introduces SAIL and BSAI lock variants absent in the SI line. Since this specific SKU lacks the -S magnet, it 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 SI80X530 Is Used
Long-Stroke Diversion
Pushes heavy pallets laterally across a 530 mm gap using the 2513 N push force at 0.5 MPa, requiring external guides to prevent rod bending.
Press Ejection
Ejects molded components from machinery using the 4523 N push force at 0.9 MPa, relying on 36 mm cushions to absorb end-of-stroke impact.
Replacing the Airtac SI80 Standard Air Cylinder SI80X530 with the SAI80X530
To replace the SI80X530, order the SAI80X530 and verify your existing fixture matches the ISO 15552 mounting interface, 80 mm bore, 530 mm stroke, G3/8 port, and M20x1.5 rod thread. Because this non-magnetic SKU cannot host a sensor, switch tracking requires upgrading to an -S designated SAI model. For sizing alternatives, a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. Note that a plain cylinder drifts without live air; the 36 mm cushions only decelerate near stroke ends. For secure load holding, consider an external pilot check valve, rod lock, or the SAIL/BSAI lock variants. Finally, the 530 mm stroke demands external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X530
- ✓ 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 SI80X530 FAQ
Yes, the SI80X530 is discontinued. The direct replacement is the SAI80X530, which shares the identical ISO 15552 mounting interface, 80 mm bore, 530 mm stroke, output force, G3/8 port, and accessories.
The bore is 80 mm with a G3/8 port. 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 max of 513 kgf at 1.0 MPa.
