This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX130S, 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 SI80BX130S
The AirTAC SI80 Standard Air Cylinder SI80BX130S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 130mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX130S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX130S
The AirTAC SI80BX130S is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore, 130mm stroke, and a SUS304 stainless piston rod. Delivering 2513 N push force at 0.5 MPa, it is replaced by the SAI80BX130S. This direct upgrade keeps the same G3/8 port, M20x1.5 thread, and ISO 15552 mounting interface.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure. The original -S magnet works with CS1-B/DS1-B sensors, while SAI uses current AirTAC switches. For load holding, explore the SAIL or BSAI lock variants, as cushions only decelerate.

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 SAI80BX130S 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 SI80BX130S Is Used
Bottle Divert Gate
Actuates a stainless diverter arm on a washdown packaging line, utilizing the SUS304 rod for corrosion resistance and 2513 N to push fully loaded cartons.
Press Ejection
Provides reliable ejection of machined aluminum parts from a fixture, using the 130 mm stroke and adjustable 36 mm air cushions to decelerate at stroke end.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX130S with the SAI80BX130S
To replace this SI80BX130S, order the SAI80BX130S. Confirm the ISO 15552 mounting interface, 80mm bore, 130mm stroke, G3/8 port, and your specific mounting accessory. The -B rod is SUS304 stainless steel, and the -S magnet allows position sensing. When sizing, note the 80mm bore yields 2513 N push at 0.5 MPa; if downsizing, a 63mm bore offers 1559 N, while a 100mm bore provides 3927 N. A plain cylinder drifts on air loss—cushions only decelerate—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX130S
- ✓ 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 SI80BX130S FAQ
Yes, the SI80BX130S is discontinued. The direct replacement is the SAI80BX130S. It is dimensionally interchangeable per ISO 15552, retaining the same 80mm bore, 130mm stroke, 2513 N force, G3/8 port, and mounting interface, but adds an upgraded piston seal.
The 80mm bore uses a G3/8 air port and features a 25mm rod with an M20x1.5 thread. Force output is 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 max of 513 kgf at 1.0 MPa.
