This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X80SH, 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 SI80X80SH
The AirTAC SI80 Standard Air Cylinder SI80X80SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 80mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X80SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X80SH
The AirTAC SI80X80SH is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore, 80 mm stroke, and a -SH configuration (magnet and Viton H high-temperature seals). Delivering 2513 N push force at 0.5 MPa through a G3/8 port, this legacy unit is replaced by the SAI80X80SH. The SAI direct maintains the exact ISO 15552 mounting interface, bore, stroke, and force, fitting existing fixtures perfectly.
The SAI upgrade features a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The -H seal allows operation up to 150 C, and the -S magnet enables CS1-B/DS1-B sensors.

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 SAI80X80SH 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 SI80X80SH Is Used
High-Temperature Forming
Ideal for pressing or clamping parts in hot environments using the Viton H seal rated for 150 C, providing 2513 N of thrust at 0.5 MPa.
Pallet Positioning
Moves or stops 80 mm pallets in conveyor lines, safely handling a 1508 N working load with its 80 mm stroke and integrated magnet.
Replacing the Airtac SI80 Standard Air Cylinder SI80X80SH with the SAI80X80SH
To replace the SI80X80SH, order the SAI80X80SH. Verify the ISO 15552 mounting interface, 80 mm stroke, G3/8 port, and M20x1.5 rod thread. The -S magnet works with CS1-B/DS1-B switches, while the SAI uses current AirTAC sensors. The -H Viton seal handles up to 150 C. If sizing down, a 63 mm bore yields 1559 N at 0.5 MPa; sizing up to 100 mm provides 3927 N. Note that a plain cylinder drifts without live air; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The SAI family also offers the SAIF valve for bores up to 100.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X80SH
- ✓ 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 SI80X80SH FAQ
Yes, the SI80X80SH is discontinued. The direct replacement is the SAI80X80SH. It shares the same ISO 15552 mounting interface, 80 mm bore, 80 mm stroke, force, and G3/8 port, fitting directly into existing setups.
The G3/8 port feeds a 25 mm rod. Force ratings are 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 maximum theoretical force of 513 kgf at 1.0 MPa.
