This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X600S, 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 SI80X600S
The AirTAC SI80 Standard Air Cylinder SI80X600S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X600S
The AirTAC SI80X600S is a discontinued double-acting ISO 15552 profile cylinder with a 600 mm stroke and an 80 mm bore, delivering 2513 N push force at 0.5 MPa. It features a G3/8 port, a Ø25 mm rod, and a built-in magnet for CS1-B/DS1-B switches. AirTAC replaced this legacy unit with the SAI80X600S.
The SAI80X600S is a direct replacement matching the exact ISO 15552 mounting interface, bore, and force. It upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAI80X600S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI80 Standard Air Cylinder SI80X600S Is Used
Long-Stroke Diversion
Pushes heavy pallets across 600 mm transfer lines using the 2513 N thrust at 0.5 MPa, guided externally to prevent rod bending.
Large Press Ejection
Ejects formed parts from machinery using the 513 kgf maximum force, relying on the 36 mm adjustable air cushions to decelerate at stroke end.
Replacing the Airtac SI80 Standard Air Cylinder SI80X600S with the SAI80X600S
To replace the SI80X600S, order the SAI80X600S and confirm the ISO 15552 mounting accessory, G3/8 port, and -S magnet for current AirTAC switches. Sizing down to a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. A plain cylinder drifts on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. At 600 mm stroke, use external guides to prevent rod bending from side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X600S
- ✓ 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 SI80X600S FAQ
Yes, the SI80X600S is discontinued. The direct replacement is the SAI80X600S. It shares the same ISO 15552 mounting interface, 80 mm bore, 600 mm stroke, and G3/8 port, fitting existing fixtures perfectly.
It has a G3/8 port and provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical max of 513 kgf at 1.0 MPa. Speed is 30-800 mm/s.
