This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1100, 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 SI80X1100
The AirTAC SI80 Standard Air Cylinder SI80X1100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1100
The AirTAC SI80X1100 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 1100 mm stroke. It delivers 2513 N push force at 0.5 MPa via a G3/8 port. The direct replacement is the SAI80X1100, matching the bore, stroke, force, port, and ISO 15552 mounting interface for existing fixtures.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this SKU lacks a magnet (-S) so it cannot take CS1-B/DS1-B sensors. The SAI family also adds SAIL, SAIF, and BSAI lock variants.

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 SI80X1100 Is Used
Long-Stroke Material Transfer
Drives heavy pallets 1100 mm between processing stations using 2513 N of push force at 0.5 MPa.
Large Assembly Fixtures
Actuates heavy clamping arms over a 1100 mm reach, relying on the 36 mm adjustable air cushions to decelerate at stroke end.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1100 with the SAI80X1100
To replace the SI80X1100, order the SAI80X1100. Verify your ISO 15552 mounting interface (LB, FA, FB, CA, CB, TC), the G3/8 port thread (PT, G, or NPT), and the M20x1.5 rod end. This non-magnet SKU cannot accept position sensors; if sensing is needed, specify an SAI model with the S magnet option for current AirTAC switches. Sizing both ways: the 80 mm bore yields 2513 N push at 0.5 MPa (3518 N at 0.7), while a neighbouring 63 mm bore offers 1559 N. Because stroke is 1100 mm, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1100
- ✓ 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 SI80X1100 FAQ
Yes, the SI80X1100 is discontinued. The direct replacement is the SAI80X1100. It is dimensionally interchangeable per ISO 15552, retaining the same 80 mm bore, 1100 mm stroke, output force, G3/8 port, and mounting accessories.
The bore is 80 mm with a G3/8 air port. 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 theoretical max of 513 kgf at 1.0 MPa. Speed is 30-800 mm/s.
