This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX230S, 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 SI80BX230S
The AirTAC SI80 Standard Air Cylinder SI80BX230S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 230mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX230S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX230S
The AirTAC SI80BX230S is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel, adjustable air cushions, and a SUS304 stainless steel piston rod. Delivering 2513 N push force at 0.5 MPa, it is superseded by the SAI80BX230S direct replacement. This upgrade retains the exact 80 mm bore, 230 mm stroke, G3/8 port, and ISO 15552 mounting interface, but features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
The original SI -S magnet supports legacy CS1-B/DS1-B sensors, while the SAI family uses current AirTAC switches. The SAI line also introduces SAIL, SAIF, and BSAI lock variants absent in the SI series.

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 SAI80BX230S 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 SI80BX230S Is Used
Food-Grade Diversion
Leverages the SUS304 rod for washdown resistance while providing 2513 N push force to divert heavy packaged goods on processing lines.
Press Ejection
Absorbs shock using adjustable 36 mm cushions to eject formed parts reliably in automated press operations.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX230S with the SAI80BX230S
To replace the discontinued SI80BX230S, order the SAI80BX230S. Verify your ISO 15552 mounting interface, 230 mm stroke, G3/8 port, and accessory type. The -B rod is SUS304 stainless steel and the -S magnet works with legacy CS1-B/DS1-B switches. For sizing both ways: a neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. At 230 mm stroke, guide side-loads to prevent rod bending. A plain cylinder drifts without live air; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX230S
- ✓ 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 SI80BX230S FAQ
Yes, the SI80BX230S is discontinued. The direct replacement is the SAI80BX230S. It shares the same ISO 15552 mounting interface, 80 mm bore, 230 mm stroke, output force, and G3/8 port, fitting existing fixtures perfectly.
The G3/8 port bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N at 0.9 MPa, and a theoretical max of 513 kgf at 1.0 MPa. It operates at 30-800 mm/s.
