This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X10S, 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 SI32X10S
The AirTAC SI32 Standard Air Cylinder SI32X10S 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 SAI32X10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X10S
The AirTAC SI32X10S 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. AirTAC replaced this legacy unit with the SAI32X10S, a direct upgrade sharing the exact interface, stroke, and force.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note that 10mm is a nonstandard stroke below the typical minimum, and this -S variant carries a piston magnet for legacy CS1-B/DS1-B sensors.

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 SAI32X10S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32X10S Is Used
Small Part Clamping
Ideal for compact fixtures requiring short 10mm movements to hold light components during machining or assembly.
Ejector Mechanisms
Provides a quick 402N push at 0.5MPa to eject small finished parts from automated test jigs or packaging lines.
Gate Diverting
Suitable for actuating small pneumatic flaps or diverter gates in low-force material handling systems.
Replacing the Airtac SI32 Standard Air Cylinder SI32X10S with the SAI32X10S
To replace the SI32X10S, order the SAI32X10S. Confirm the ISO 15552 mounting interface, 32mm bore, 10mm stroke, G1/8 port (PT/G/NPT thread), and mounting accessory. The -S denotes a magnet for CS1-B/DS1-B switches; the SAI uses current AirTAC switches. Sizing both ways: if 402N push at 0.5MPa is insufficient, step up to the 40mm bore (628N); if too much, no smaller ISO 15552 bore exists. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The 10mm stroke is nonstandard; verify exact rod-end thread M10x1.25 requirements.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X10S
- ✓ 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 SI32X10S FAQ
Yes, the AirTAC SI32X10S is discontinued. The direct replacement is the SAI32X10S. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 10mm stroke, G1/8 port, and mounting fixtures perfectly.
The 32mm bore provides 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. Operating speed is 30-800mm/s. It features a 12mm rod, M10x1.25 thread, and 27mm cushions.
