This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX165S, 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 SI32 Standard Air Cylinder SI32AX165S
The AirTAC SI32 Standard Air Cylinder SI32AX165S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 165mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX165S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX165S
The AirTAC SI32AX165S is a discontinued double-acting ISO 15552 profile cylinder featuring a 32mm bore, 165mm stroke, and a SUS420J2 stainless steel rod. It delivers 402 N push force at 0.5 MPa via a G1/8 port. AirTAC replaced this legacy unit with the SAI32AX165S, a direct sharing the exact ISO 15552 mounting interface, bore, stroke, and output force.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The -S magnet works with legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL, SAIF, and BSAI lock variants.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |

Where the Airtac SI32 Standard Air Cylinder SI32AX165S Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably push lightweight machined components out of a fixture.
Package Diverting
Actuates a routing gate on a conveyor line, with the 165 mm stroke providing precise travel.
Lab Test Fixtures
The SUS420J2 stainless rod option excels in humid or mildly corrosive laboratory testing environments.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX165S with the SAI32AX165S
To replace the SI32AX165S, order the SAI32AX165S and confirm the ISO 15552 mounting interface, 165mm stroke, G1/8 port, and your specific mounting accessory. The -A denotes a SUS420J2 stainless rod for corrosion resistance, and -S means the magnet is present for CS1-B/DS1-B switches. If you need higher force, the neighbouring 40mm bore provides 628 N push at 0.5 MPa; if you need less, consider smaller profiles. A plain cylinder does not hold load without live air—the cushion only decelerates—so for holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. At 165mm stroke, side-load and rod-bending risks are minimal, but always guide the load.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX165S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI32 Standard Air Cylinder SI32AX165S FAQ
Yes, the SI32AX165S is discontinued. The direct replacement is the SAI32AX165S. It shares the identical ISO 15552 mounting interface, 32mm bore, 165mm stroke, output force, and G1/8 port, fitting existing fixtures perfectly.
This 32mm bore cylinder has a G1/8 port. It delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa.
