This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1075, 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 SI80X1075
The AirTAC SI80 Standard Air Cylinder SI80X1075 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1075mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1075, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1075
The AirTAC SI80X1075 is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 1075mm stroke. Delivering 2513N push force at 0.5MPa via a G3/8 port, it is replaced by the SAI80X1075. This direct upgrade shares identical mounting, bore, stroke, and force specs, fitting existing fixtures seamlessly.
The SAI features an upgraded piston seal with two Y-shaped elements for low start-up pressure and long life. It also introduces SAIL, SAIF, and BSAI lock variants the SI lacked. Since this specific SI SKU lacks a magnet, it cannot accept a sensor. The 36mm cushions decelerate but do not hold loads without air.

Where the Airtac SI80 Standard Air Cylinder SI80X1075 Is Used
Long-Stroke Diversion
Pushes heavy pallets across transfer lines using the 1075mm stroke and 2513N force at 0.5MPa.
Large Press Ejection
Ejects molded parts from heavy machinery, relying on the 36mm adjustable cushions to decelerate.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1075 with the SAI80X1075
To replace the SI80X1075, order the SAI80X1075. Confirm the ISO 15552 interface, 80mm bore, 1075mm stroke, G3/8 port, and M20x1.5 rod thread. Because this SKU has no magnet, it cannot accept CS1-B/DS1-B sensors; order a magnet-equipped SAI if sensing is needed. For sizing, a 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore yields 3927N. Note that a plain cylinder drifts without air; for load holding, use the SAIL or BSAI lock variant, or an external pilot check valve. Finally, at 1075mm, prevent rod bending by guiding the load externally to avoid side-loading.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1075
- ✓ 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 SI80X1075 FAQ
Yes, the SI80X1075 is discontinued. The direct replacement is the SAI80X1075. It is dimensionally interchangeable per ISO 15552, retaining the same 80mm bore, 1075mm stroke, 4523N force, G3/8 port, and mounting interface.
It features a G3/8 air 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 max of 513kgf at 1.0MPa.
