This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X410S, 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 SI80X410S
The AirTAC SI80 Standard Air Cylinder SI80X410S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 410mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X410S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X410S
The AirTAC SI80X410S is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel. It delivers 2513 N push and 2268 N pull at 0.5 MPa through a G3/8 port. AirTAC replaced this legacy unit with the SAI80X410S, a direct sharing the same 80 mm bore, 410 mm stroke, M20x1.5 rod thread, and mounting interface.
The SAI upgrade features a revised piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also introduces SAIL, SAIF, and BSAI lock variants absent from 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 SI80X410S Is Used
Pallet Diversion
Actuates heavy lane diverters on packaging lines, utilizing the 2513 N push force at 0.5 MPa to shift loaded pallets smoothly.
Press Ejection
Drives long-stroke ejection mechanisms in stamping presses, relying on the 410 mm travel to clear large formed parts.
Replacing the Airtac SI80 Standard Air Cylinder SI80X410S with the SAI80X410S
To replace the SI80X410S, order the SAI80X410S and confirm your ISO 15552 mounting accessories (LB, FA, CA, TC), G3/8 port threads, and the -S magnet for CS1-B/DS1-B sensors. If you need more force, the 100 mm bore yields 3927 N push at 0.5 MPa; if less is required, the 63 mm bore provides 1559 N. Because the 410 mm stroke increases side-load and rod-bending risks, use an external guide to prevent premature seal wear. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding consider an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X410S
- ✓ 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 SI80X410S FAQ
Yes, the SI80X410S is discontinued. The direct replacement is the SAI80X410S. It shares the identical ISO 15552 mounting interface, 80 mm bore, 410 mm stroke, output force, and G3/8 port, fitting directly into existing fixtures.
This double-acting cylinder operates at 30-800 mm/s. It generates 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 force of 513 kgf at 1.0 MPa.
