This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X800SH, 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 SI80X800SH
The AirTAC SI80 Standard Air Cylinder SI80X800SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 800mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X800SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X800SH
The AirTAC SI80X800SH is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 800mm stroke, delivering 2513N push force at 0.5MPa via a G3/8 port. The direct replacement is the SAI80X800SH, which matches the original mounting interface, bore, stroke, force and port size. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
This -SH configuration includes a piston magnet for legacy CS1-B/DS1-B sensors and a Viton H seal for 0-150C high-temperature environments. Note that the SAI family also adds lock and valve variants (SAIL, BSAI, SAIF) absent in the SI line.

Where the Airtac SI80 Standard Air Cylinder SI80X800SH Is Used
Long-Stroke Diversion
Drives large packages across wide conveyor belts using the 800mm stroke, relying on external guides to prevent rod bending during lateral transfers.
High-Temperature Forming
Actuates press doors or insulation shields in hot zones up to 150C, leveraging the Viton H seals for thermal endurance.
Replacing the Airtac SI80 Standard Air Cylinder SI80X800SH with the SAI80X800SH
To replace the SI80X800SH, order the SAI80X800SH. Confirm the ISO 15552 mounting interface (LB, FA, CA, TC, etc.), the 80mm bore, 800mm stroke, G3/8 port, and the -S magnet / -H Viton seal options. Sizing both ways: a 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore yields 3927N. Because this is an 800mm stroke, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve, rod lock, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X800SH
- ✓ 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 SI80X800SH FAQ
Yes, the SI80X800SH is discontinued. The direct replacement is the SAI80X800SH. It is dimensionally interchangeable per ISO 15552, matching the 80mm bore, 800mm stroke, 2513N force, G3/8 port, and mounting accessories, so it fits existing fixtures.
The G3/8 port bore delivers a push of 2513N and pull of 2268N at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a maximum theoretical force of 513kgf at 1.0MPa. Operating speed is 30-800mm/s.
