This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X100H, 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 SI80X100H
The AirTAC SI80 Standard Air Cylinder SI80X100H 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 SAI80X100H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X100H
The AirTAC SI80X100H is a discontinued double-acting ISO 15552 profile cylinder featuring an extruded aluminum barrel and a Viton H high-temperature seal rated for 0 to 150 C. Delivering 2513 N push force at 0.5 MPa through a G3/8 port, it is replaced by the SAI80X100H.
The SAI direct retains the exact 80 mm bore, 100 mm stroke, M20x1.5 rod thread, and mounting interface. 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 | — |

Where the Airtac SI80 Standard Air Cylinder SI80X100H Is Used
High-Tactile Pressing
Applies 2513 N at 0.5 MPa for seating bearings or forming light gauge materials where the Viton H seal survives sustained 150 C ambient heat.
Hot Diverters
Drives diverter arms on warm conveyors; the 100 mm stroke shifts packages rapidly while the G3/8 port maintains adequate flow.
Replacing the Airtac SI80 Standard Air Cylinder SI80X100H with the SAI80X100H
To replace the SI80X100H, order the SAI80X100H confirming the ISO 15552 interface, 80 mm bore, 100 mm stroke, G3/8 port, and Viton H seal. For sizing, a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. This plain cylinder drifts on air loss as the cushion only decelerates; for load holding use the SAIL lock, BSAI clamp-lock, or an external pilot check valve. Since this SKU lacks a magnet, no sensor can be fitted.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X100H
- ✓ 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 SI80X100H FAQ
Yes, the SI80X100H is discontinued. The direct replacement is the SAI80X100H. It shares the same ISO 15552 mounting interface, 80 mm bore, 100 mm stroke, output force, G3/8 port, and Viton H seal, fitting existing fixtures perfectly.
