This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80AX95S, 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 SI80AX95S
The AirTAC SI80 Standard Air Cylinder SI80AX95S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 95mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80AX95S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80AX95S
The AirTAC SI80AX95S is a discontinued double-acting ISO 15552 profile cylinder featuring an 80 mm bore, 95 mm stroke, and a SUS420J2 stainless steel piston rod. It delivers 2513 N of push force at 0.5 MPa through its G3/8 port. As a legacy unit, it must be replaced by the current-production SAI80AX95S. This upgrade is a direct: the ISO 15552 mounting interface, bore, stroke, output force, and port size remain identical, so it fits existing fixtures perfectly.
The SAI replacement introduces an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and extended life. This -S model includes a piston magnet for legacy CS1-B/DS1-B sensors, and the SAI family now offers SAIL, SAIF, and BSAI variants that the SI line lacked.

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 SAI80AX95S 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 SI80AX95S Is Used
Stainless Rod Clamping
Ideal for machining fixtures requiring corrosion resistance, using the SUS420J2 rod to apply 2513 N of clamping thrust at 0.5 MPa.
Replacing the Airtac SI80 Standard Air Cylinder SI80AX95S with the SAI80AX95S
To replace the discontinued SI80AX95S, order the SAI80AX95S. Confirm the ISO 15552 mounting interface, the 80 mm bore, the 95 mm stroke, the G3/8 port, and your mounting accessory. Because this unit has the -S magnet, it supports CS1-B/DS1-B legacy switches, while the SAI replacement uses current AirTAC sensors. The -A rod code specifies the SUS420J2 stainless steel piston rod for corrosion resistance. If you need to size both ways, a 63 mm bore yields 1559 N push at 0.5 MPa, whereas a 100 mm bore yields 3927 N. Remember that a plain ISO 15552 cylinder does not hold load without live air; the adjustable 36 mm cushions only decelerate. For load holding on air loss, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80AX95S
- ✓ 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 SI80AX95S FAQ
Yes, the SI80AX95S is discontinued. The direct replacement is the SAI80AX95S. It shares the same ISO 15552 mounting interface, 80 mm bore, 95 mm stroke, output force, and G3/8 port, fitting directly into existing fixtures.
This double-acting cylinder uses a G3/8 air port. It delivers 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 maximum force of 513 kgf at 1.0 MPa.
