This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X226S, 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 SI80X226S
The AirTAC SI80 Standard Air Cylinder SI80X226S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 226mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X226S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X226S
The AirTAC SI80X226S is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel and a 226 mm stroke. Delivering 2513 N push force at 0.5 MPa, it features a Ø25 mm piston rod, M20x1.5 rod thread, and a G3/8 air port. The direct replacement is the SAI80X226S, matching the exact bore, stroke, force, port, and ISO 15552 mounting interface for existing fixtures.
Upgrading to the SAI brings an advanced piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also introduces lock and valve variants (SAIL, SAIF, BSAI) absent in the legacy line, and the -S magnet on this unit supports CS1-B/DS1-B switches.

Where the Airtac SI80 Standard Air Cylinder SI80X226S Is Used
Pallet Diversion
Provides the 2513 N push force needed to divert heavy pallets on packaging lines, utilizing the 226 mm stroke to clear adjacent lanes.
Press Ejection
Ejects formed metal components from press beds, absorbing end-of-stroke impact via the 36 mm adjustable air cushion.
Replacing the Airtac SI80 Standard Air Cylinder SI80X226S with the SAI80X226S
To replace the SI80X226S, order the SAI80X226S and verify the ISO 15552 mounting interface, 80 mm bore, 226 mm stroke, G3/8 port, and magnet option. Note that 226 mm is a nonstandard stroke length; ensure your SAI supplier can accommodate it. If sizing down, the 63 mm bore yields 1559 N push at 0.5 MPa; if sizing up, the 100 mm bore provides 3927 N. Because 226 mm is a longer stroke, guide the load to prevent rod bending and side-load damage. A plain cylinder drifts without live air—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for load holding. The -S suffix means it accepts CS1-B/DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X226S
- ✓ 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 SI80X226S FAQ
Yes, the SI80X226S is discontinued. The direct replacement is the SAI80X226S. It shares the same ISO 15552 mounting interface, 80 mm bore, 226 mm stroke, output force, and G3/8 port, fitting directly into existing fixtures.
The 80 mm bore features a G3/8 air port and delivers 2513 N push and 2268 N pull at 0.5 MPa. At 0.7 MPa it pushes 3518 N, and the theoretical maximum force is 513 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
