This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80AX600, 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 SI80AX600
The AirTAC SI80 Standard Air Cylinder SI80AX600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80AX600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80AX600
The AirTAC SI80AX600 is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 600mm stroke. It delivers 2513N push force at 0.5MPa and features a SUS420J2 stainless piston rod. The direct replacement is the SAI80AX600, matching the G3/8 port, M20x1.5 thread, and mounting interface exactly.
Because this SKU lacks a magnet, it cannot accept position switches. The SAI upgrade introduces a two-piece Y-shaped piston seal for low start-up pressure and long life.

Where the Airtac SI80 Standard Air Cylinder SI80AX600 Is Used
Long-Stroke Diverting
Drives large sorting gates on packaging lines over a 600mm travel, relying on the SUS420J2 stainless rod for humid washdown environments.
Pallet Push-Off
Pushes heavy pallets laterally off rollers, utilizing the 2513N thrust at 0.5MPa to overcome initial friction without needing a magnet.
Material Lowering
Lowers 100kg fixtures vertically, requiring external guides for the extended 600mm stroke and a pilot check valve to prevent drifting on air loss.
Replacing the Airtac SI80 Standard Air Cylinder SI80AX600 with the SAI80AX600
To replace the SI80AX600, order the SAI80AX600 and confirm the ISO 15552 mounting interface, 80mm bore, 600mm stroke, G3/8 port, and SUS420J2 rod. Neighbouring bores are 63mm (1559N push at 0.5MPa) and 100mm (3927N push). Note that this non-magnetic SKU cannot hold a load without live air; the 36mm cushions only decelerate. For load-holding, use an external pilot check valve or the SAIL/BSAI lock variants. With a 600mm stroke, use external guides to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80AX600
- ✓ 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 SI80AX600 FAQ
Yes, the SI80AX600 is discontinued. The direct replacement is the SAI80AX600. It is dimensionally interchangeable per ISO 15552, keeping the same 80mm bore, 600mm stroke, force, G3/8 port, and mounting fixtures.
It uses a G3/8 air port. At 0.5MPa it pushes 2513N and pulls 2268N. At 0.7MPa push is 3518N, and at 0.9MPa it is 4523N. The theoretical max force is 513kgf at 1.0MPa.
