This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX10, 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 SI32AX10
The AirTAC SI32 Standard Air Cylinder SI32AX10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 10mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX10
The AirTAC SI32AX10 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 10mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The direct replacement is the SAI32AX10, matching the exact interface, force, and mounting. This 10mm stroke is nonstandard (below the 25mm minimum).
The SAI upgrade features an improved piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The -A suffix denotes a SUS420J2 stainless steel rod for corrosion resistance. Without a -S suffix, this SKU cannot accept a sensor.

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 SI32AX10 Is Used
Short-Stroke Clamping
Ideal for compact clamping tasks in machining fixtures where a 20kg holding force and 10mm travel secure lightweight components without requiring full stroke lengths.
Ejector Mechanisms
Suited for small-part ejection in automated assembly lines, providing rapid 402N actuation to push parts out of nests reliably within tight spatial constraints.
Valve Actuation
Used to pilot or toggle mechanical valves and diverters in process equipment, where the SUS420J2 stainless rod offers necessary moisture resistance.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX10 with the SAI32AX10
To replace the SI32AX10, order the SAI32AX10. Verify the ISO 15552 mounting interface, 32mm bore, 10mm stroke, G1/8 port, and -A stainless rod. Because this lacks a -S suffix, it cannot take a magnetic switch; if sensing is needed, select an SAI model with the S option for current AirTAC switches. For sizing, the 32mm bore yields 402N push at 0.5MPa; if less force is acceptable, a smaller bore may suffice, while heavier loads require stepping up. 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 specify an SAIL or BSAI lock variant. Note: at this 10mm short stroke, side-load risks are minimal, but ensure precise alignment to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX10
- ✓ 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 SI32AX10 FAQ
Yes, the AirTAC SI32AX10 is discontinued. The direct replacement is the SAI32AX10. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 10mm stroke, G1/8 port, and mounting interface.
This 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 maximum of 82kgf at 1.0MPa. Operating speed is 30-800mm/s.
