This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the drop-in replacement SAI32AX950S, 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 SI32AX950S
The AirTAC Airtac SI32 Standard Air Cylinder SI32AX950S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 950mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAI32AX950S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX950S
The AirTAC SI32AX950S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 950mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The exact drop-in replacement is the SAI32AX950S, matching the bore, stroke, force, port and ISO 15552 mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. It also adds SAIL, SAIF and BSAI variants the SI lacked. This -A rod uses SUS420J2 stainless steel, and the -S magnet works with legacy CS1-B/DS1-B sensors. Expect a safe working load of ~241N (60% of [email protected]) or a ~20kg vertical lift with a 2:1 margin.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32AX950S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32AX950S Is Used
Light-Part Ejection
Uses the 402N push force at 0.5MPa to push light finished parts out of a machining center, taking advantage of the compact 32mm bore.
950mm Sorter Diverter
The 950mm stroke reaches across a conveyor belt to divert small packages, requiring external guides to prevent rod bending on the long extension.
Stainless Rod Transfer
The SUS420J2 stainless rod (-A option) suits washdown transfer stations, resisting corrosion while handling a safe working load of 241N.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX950S with the SAI32AX950S
To replace the SI32AX950S, order the SAI32AX950S. Confirm the ISO 15552 mounting interface, the 32mm bore, 950mm stroke, G1/8 port (PT/G/NPT thread), the SUS420J2 stainless rod (-A) and the magnet (-S). Sizing both ways: a 40mm bore gives 628N [email protected], while dropping to a 25mm bore yields less force. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding, or choose the SAIL/BSAI lock variant. At 950mm, prevent rod bending by guiding the load externally.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX950S
- ✓ 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 SI32AX950S FAQ
Yes, the SI32AX950S is discontinued. The exact drop-in replacement is the SAI32AX950S. It is dimensionally interchangeable per ISO 15552, keeping the same 32mm bore, 950mm stroke, G1/8 port and mounting interface.
This 32mm bore double-acting cylinder uses a G1/8 port. It generates 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa.
