This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X100SH, 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 SI80X100SH
The AirTAC SI80 Standard Air Cylinder SI80X100SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X100SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X100SH
The AirTAC SI80X100SH is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80X100SH, matching the bore, stroke, force, and ISO 15552 mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SI unit includes a magnet for CS1-B/DS1-B sensors and a Viton H seal for 0-150 C heat.

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 SAI80X100SH 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 SI80X100SH Is Used
Heavy Press Clamping
Applies 2513 N of clamping force at 0.5 MPa to secure heavy metal housings during machining operations.
Pallet Diversion
Extends 100 mm to push loaded pallets onto secondary packaging lines without requiring high speed.
Hot End Ejection
Uses the Viton H seal to reliably eject 128 kg molded parts from 120 C environments without seal degradation.
Replacing the Airtac SI80 Standard Air Cylinder SI80X100SH with the SAI80X100SH
To replace the SI80X100SH, order the SAI80X100SH. Confirm the ISO 15552 mounting interface, the 80 mm bore, 100 mm stroke, G3/8 port, and your Viton H high-temperature seal requirement. The M20x1.5 rod thread and 36 mm cushions remain identical. If you need more force, the 100 mm bore offers 3927 N push at 0.5 MPa; if less is needed, the 63 mm bore provides 1559 N. A plain cylinder drifts on air loss because the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variants. The SAIF variant adds a built-in valve if needed.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X100SH
- ✓ 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 SI80X100SH FAQ
Yes, the SI80X100SH is discontinued. The direct replacement is the SAI80X100SH. It shares the same ISO 15552 mounting interface, 80 mm bore, 100 mm stroke, output force, and G3/8 port, fitting existing fixtures perfectly.
It features a G3/8 port and provides 2513 N push and 2268 N pull at 0.5 MPa. At 0.7 MPa push is 3518 N, and 4523 N at 0.9 MPa. The theoretical max force is 513 kgf at 1.0 MPa.
