This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X762S, 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 SI80X762S
The AirTAC SI80 Standard Air Cylinder SI80X762S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 762mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X762S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X762S
The AirTAC SI80X762S is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel. It delivers 2513 N push force at 0.5 MPa through an 80 mm bore. AirTAC replaced this legacy unit with the SAI80X762S, a direct replacement retaining the exact ISO 15552 mounting interface, 762 mm stroke, G3/8 port, and M20x1.5 rod thread. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B sensors, though the SAI replacement family uses current AirTAC switches. You can also specify Viton H seals for high-temperature applications up to 150 C.

Where the Airtac SI80 Standard Air Cylinder SI80X762S Is Used
Long-Stroke Diverting
Drives large sorting gates on packaging lines where the 762 mm travel and 2513 N force at 0.5 MPa are required to push heavy cartons across wide belts.
Pallet Handling
Actuates lifting mechanisms or push-off arms in automated storage systems, utilizing the 80 mm bore to move loads safely under the 1508 N working threshold.
Material Ejection
Ejects molded parts or sheet stock from machinery, relying on the adjustable 36 mm air cushions to decelerate the rod smoothly at stroke ends.
Replacing the Airtac SI80 Standard Air Cylinder SI80X762S with the SAI80X762S
To replace the SI80X762S, order the SAI80X762S. Verify your ISO 15552 mounting accessory (LB foot, FA flange, or TC trunnion), the G3/8 air port, and the M20x1.5 rod thread. If you need to size both ways, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Because the 762 mm stroke is long, use an external guide to prevent rod bending and side-load damage. A plain cylinder does not hold load without live air; the cushion only decelerates. For load holding on air loss, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X762S
- ✓ 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 SI80X762S FAQ
Yes, the AirTAC SI80X762S is discontinued. The direct replacement is the SAI80X762S. It is dimensionally interchangeable per ISO 15552, matching the 80 mm bore, 762 mm stroke, G3/8 port, and mounting interface, so it drops directly into existing fixtures.
The 80 mm bore uses a G3/8 air port and a 25 mm piston rod. It generates 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 maximum force of 513 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
