This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1000SN, 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 SI80X1000SN
The AirTAC SI80 Standard Air Cylinder SI80X1000SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1000SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1000SN
The AirTAC SI80X1000SN is a discontinued double-acting ISO 15552 profile cylinder featuring an extruded aluminum barrel and adjustable air cushions. It delivers 2513 N of push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80X1000SN, matching the 80mm bore, 1000mm stroke, and mounting interface.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The original SI line lacked the SAIL air-released lock, SAIF built-in valve, and BSAI clamp-lock variants now available. This unit includes a piston magnet for CS1-B/DS1-B sensors and an NBR seal rated for -20 to +70 C.

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 SAI80X1000SN 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 SI80X1000SN Is Used
Long-Stroke Material Transfer
Drives heavy pallets across 1000mm transit zones where 2513 N of push force at 0.5 MPa is required to overcome friction.
Large Fixture Positioning
Indexes heavy welding fixtures along a 1-meter path, requiring external guide rails to prevent rod bending.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1000SN with the SAI80X1000SN
To replace the SI80X1000SN, order the SAI80X1000SN direct, verifying the ISO 15552 mounting interface, M20x1.5 rod thread, G3/8 port, and the -S magnet for legacy CS1-B/DS1-B switches. The -N denotes the standard NBR seal; a Viton H option exists for high heat. Sizing both ways: an 80mm bore yields 2513 N push at 0.5 MPa, while a 63mm bore yields 1559 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 variant. Because the 1000mm stroke is long, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1000SN
- ✓ 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 SI80X1000SN FAQ
Yes, the SI80X1000SN is discontinued. The direct replacement is the SAI80X1000SN. It is dimensionally interchangeable per ISO 15552, retaining the same 80mm bore, 1000mm stroke, output force, G3/8 port, and mounting accessories.
The G3/8 port feeds a 25mm rod delivering 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 maximum force is 513 kgf at 1.0 MPa.
