This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX160SH, 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 SI80BX160SH
The AirTAC SI80 Standard Air Cylinder SI80BX160SH 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 SAI80BX160SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX160SH
The AirTAC SI80BX160SH is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore, 160mm stroke, G3/8 port, and a SUS304 stainless steel rod. Delivering 2513 N push force at 0.5 MPa, it is replaced by the SAI80BX160SH. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, and force.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also adds SAIL, SAIF, and BSAI lock variants absent from the SI line. The -H Viton seal allows 0-150 C operation, while the -S magnet works with legacy CS1-B/DS1-B sensors.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAI80BX160SH produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI80 Standard Air Cylinder SI80BX160SH Is Used
High-Temp Forming Press
Ideal for actuating small presses or forming dies in heated zones, utilizing the -H Viton seals rated for 0-150 C and the robust 2513 N push force at 0.5 MPa.
Washdown Diverters
The -B SUS304 stainless piston rod provides corrosion resistance for diverting gates or product routing in washdown environments, powered by a 2268 N pull force.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX160SH with the SAI80BX160SH
To replace the SI80BX160SH, order the SAI80BX160SH. Confirm the ISO 15552 mounting interface, 80mm bore, 160mm stroke, G3/8 port, and your specific mounting accessory. The SAI is a direct retaining all dimensions and force. The -B rod is SUS304 stainless steel, and the -H seal specifies Viton for 0-150 C high-temperature environments. The -S magnet enables legacy CS1-B/DS1-B switches (the SAI uses current AirTAC switches). If downsizing, a 63mm bore yields 1559 N push at 0.5 MPa; if upsizing, a 100mm bore yields 3927 N. Note: a plain cylinder drifts on air loss, as the 36mm adjustable cushion only decelerates near stroke end. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX160SH
- ✓ 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 SI80BX160SH FAQ
