This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX100, 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 SI80BX100
The AirTAC SI80 Standard Air Cylinder SI80BX100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX100
The AirTAC SI80BX100 is a discontinued double-acting ISO 15552 profile cylinder featuring an 80mm bore and 100mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa through a G3/8 port. AirTAC replaced this EOL unit with the SAI80BX100, a direct sharing the exact ISO 15552 mounting interface, bore, stroke, force, port and accessories. The SAI upgrade utilizes two Y-shaped one-way piston seals for low start-up pressure and extended life.
This specific SKU uses a SUS304 stainless steel piston rod (-B) for corrosion resistance, but lacks a magnet so it cannot accept legacy CS1-B/DS1-B sensors. The standard cylinder does not hold load without live air; explore SAIL or BSAI lock variants if needed.

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 SAI80BX100 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 SI80BX100 Is Used
Corrosive Material Clamping
Leverages the SUS304 stainless rod to securely clamp workpieces in washdown or mildly corrosive manufacturing environments without pitting.
Heavy Package Diversion
Provides robust 2513 N push force at 0.5 MPa to deflect heavy pallets or packages on high-throughput material handling lines.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX100 with the SAI80BX100
To replace the discontinued SI80BX100, order the SAI80BX100. Verify the ISO 15552 mounting interface, 80mm bore, 100mm stroke, G3/8 port, and your specific mounting accessory. Because this SKU lacks a magnet (-S), it cannot support position sensing; if sensing is required, select an SAI80X100S model and use current AirTAC switches. The -B rod denotes SUS304 stainless steel; retain this option for corrosive environments. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so for load holding consider an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX100
- ✓ 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 SI80BX100 FAQ
Yes, the AirTAC SI80BX100 is discontinued. The direct replacement is the SAI80BX100. It shares the same ISO 15552 mounting interface, 80mm bore, 100mm stroke, output force, G3/8 port, and SUS304 stainless rod, fitting existing fixtures perfectly.
