This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X930S, 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 SI80X930S
The AirTAC SI80 Standard Air Cylinder SI80X930S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 930mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X930S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X930S
The AirTAC SI80X930S is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel and adjustable air cushions. Delivering 2513 N push force at 0.5 MPa through a G3/8 port, it is replaced by the SAI80X930S. This direct upgrade shares the exact ISO 15552 mounting interface, 80 mm bore, 930 mm stroke, and M20x1.5 rod thread.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The -S suffix means a piston magnet for CS1-B/DS1-B sensors; the SAI uses current AirTAC switches. The SAI family also adds SAIL, SAIF, and BSAI lock variants.

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 SAI80X930S 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 SI80X930S Is Used
Long-Stroke Diversion
Pushes heavy pallets across wide transfer lines using the 930 mm stroke and 2513 N force, requiring external guides to prevent rod bending.
Large Press Ejection
Ejects formed parts from heavy machinery, relying on adjustable 36 mm air cushions to decelerate the 25 mm rod at stroke ends.
Replacing the Airtac SI80 Standard Air Cylinder SI80X930S with the SAI80X930S
To replace the SI80X930S, order the SAI80X930S. Confirm the ISO 15552 mounting accessory (LB, FA, CA, TC), the G3/8 port, and the magnet. Sizing both ways: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. At 930 mm stroke, prevent rod bending by using an external guide to absorb side loads. A plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. Rod materials include carbon steel, SUS420J2 (A), or SUS304 (B); seals offer Viton H for high temp.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X930S
- ✓ 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 SI80X930S FAQ
Yes, the SI80X930S is discontinued. The direct replacement is the SAI80X930S. It shares the same ISO 15552 mounting interface, 80 mm bore, 930 mm stroke, output force, G3/8 port, and accessories, fitting existing fixtures perfectly.
The 80 mm bore 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 max force of 513 kgf at 1.0 MPa. Operating speed is 30-800 mm/s. It uses a G3/8 port and M20x1.5 rod thread.
