This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X160, 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 SI80X160
The AirTAC SI80 Standard Air Cylinder SI80X160 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X160
The AirTAC SI80X160 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 160 mm stroke. It delivers 2513 N push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80X160, which matches the original mounting interface, bore, stroke, output force and port size exactly.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note that this specific SKU lacks a magnet and cannot accept position sensors.

Where the Airtac SI80 Standard Air Cylinder SI80X160 Is Used
Press Fit Assembly
Drives bearings or pins into housings on an automated line, utilizing the 2513 N push force at 0.5 MPa to seat components reliably.
Pallet Diversion
Actuates a heavy-duty routing gate or pop-up stopper on a conveyor network, moving loaded pallets via the 128 kg vertical lift capacity.
Packaging Lift
Raises bulk corrugated cartons from a lower conveyor tier to a sealing station, taking advantage of the 160 mm stroke and 2268 N pull force.
Replacing the Airtac SI80 Standard Air Cylinder SI80X160 with the SAI80X160
To replace the SI80X160, order the SAI80X160. Confirm the ISO 15552 mounting interface (such as LB foot or TC trunnion), the 160 mm stroke, and the G3/8 port. Because this SKU has no internal magnet, it cannot support switches; if sensing is required, select an SAI80X160S. When sizing, the 80 mm bore yields 2513 N push at 0.5 MPa, while the neighbouring 63 mm bore offers 1559 N. A plain cylinder drifts on air loss because the cushion only decelerates near stroke end; for load holding, specify the SAIL lock variant or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X160
- ✓ 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 SI80X160 FAQ
Yes, the AirTAC SI80X160 is discontinued. The direct replacement is the SAI80X160. It is dimensionally interchangeable per ISO 15552, preserving the same 80 mm bore, 160 mm stroke, output force, G3/8 port and mounting accessories.
This double-acting cylinder uses a G3/8 air port. 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 of 513 kgf at 1.0 MPa.
