This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X150SCA, 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 SI80X150SCA
The AirTAC SI80 Standard Air Cylinder SI80X150SCA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X150SCA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X150SCA
The AirTAC SI80X150SCA is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 150mm stroke. It delivers 2513N push force at 0.5MPa via a G3/8 port. AirTAC replaced this legacy unit with the SAI80X150SCA, a direct sharing the exact ISO 15552 mounting interface, CA clevis, stroke and force.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. It also adds SAIL, SAIF and BSAI variants the SI lacked. The -S magnet works with CS1-B/DS1-B switches; Viton H seals raise heat to 150C.

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 SI80X150SCA Is Used
Mid-Tonnage Pressing
Applies the 3518N thrust at 0.7MPa for seating bearings or light stamping tasks within automated cells.
Pallet Diversion
Uses the 150mm stroke and CA clevis to push heavy pallets onto adjacent packaging lines smoothly.
Replacing the Airtac SI80 Standard Air Cylinder SI80X150SCA with the SAI80X150SCA
To replace the SI80X150SCA, order the SAI80X150SCA keeping the 80mm bore, 150mm stroke, G3/8 port, M20x1.5 rod thread and CA clevis mount. The ISO 15552 dimensions ensure it drops into existing fixtures. If sizing down, a 63mm bore yields 1559N at 0.5MPa; sizing up to 100mm provides 3927N. This single-rod cylinder drifts on air loss—the 36mm cushions only decelerate. For load holding, specify the SAIL lock, BSAI clamp-lock, or an external pilot check valve. The built-in magnet supports CS1-B/DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X150SCA
- ✓ 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 SI80X150SCA FAQ
Yes, the SI80X150SCA is discontinued. The direct replacement is the SAI80X150SCA. It shares the identical ISO 15552 mounting interface, 80mm bore, 150mm stroke, G3/8 port and CA clevis, fitting existing fixtures perfectly while upgrading the piston seal.
The bore is 80mm with a G3/8 port. Force output is 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a theoretical maximum of 513kgf at 1.0MPa. Operating speed is 30-800mm/s.
