This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X230S, 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 SI80X230S
The AirTAC SI80 Standard Air Cylinder SI80X230S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 230mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X230S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X230S
The AirTAC SI80X230S is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 230mm stroke. Providing 2513 N push force at 0.5 MPa via a G3/8 port, its direct replacement is the SAI80X230S, which matches the exact interface, bore, stroke, force and mounting hardware.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. The SI-SKU includes a piston magnet for legacy CS1-B/DS1-B sensors, while the SAI accepts current AirTAC switches; additionally, the SAI family adds SAIL, SAIF and BSAI lock variants the SI lacked.

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 SI80X230S Is Used
Pallet Diversion
Pushes heavy pallets onto secondary packaging lines using the 2513 N thrust at 0.5 MPa, dropping directly into existing ISO 15552 fixture holes.
Press Ejection
Ejects formed metal components from hydraulic presses, relying on the 36mm adjustable air cushions to decelerate the 230mm stroke smoothly.
Replacing the Airtac SI80 Standard Air Cylinder SI80X230S with the SAI80X230S
To replace the SI80X230S, order the SAI80X230S direct: it is dimensionally interchangeable per ISO 15552, keeping the 80mm bore, 230mm stroke, M20x1.5 rod thread and G3/8 port. Retain your existing mounting accessory (LB, FA, TC, etc.) and confirm the -S magnet for switch sensing. If sizing up or down, neighbouring bores (63mm or 100mm) alter the 0.5 MPa push force (1559 N or 3927 N respectively). For any stroke of 230mm, ensure adequate guide support to prevent rod bending under side loads. A plain cylinder does not hold load on air loss—the cushion only decelerates—so for suspended loads use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X230S
- ✓ 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 SI80X230S FAQ
Yes, the SI80X230S is discontinued. The direct replacement is the SAI80X230S. It is a true ISO 15552 profile cylinder that matches the 80mm bore, 230mm stroke, 25mm rod, G3/8 port and mounting interface, fitting existing fixtures perfectly.
The 80mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa. Operating speed is 30-800 mm/s, with a 36mm adjustable air cushion at both ends.
