This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X30S, 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 SI32X30S
The AirTAC SI32 Standard Air Cylinder SI32X30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 30mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X30S
The AirTAC SI32X30S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 30mm stroke, delivering 402N push force at 0.5MPa via a G1/8 port. The direct replacement is the SAI32X30S, which matches the exact mounting interface, bore, stroke, output force, and port size.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. Your SI32X30S has a magnet for CS1-B/DS1-B switches, while the SAI uses current AirTAC switches.

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 SI32X30S Is Used
Small Part Clamping
Ideal for compact fixtures providing 402N of clamping force to hold light components during machining or assembly.
Ejector Mechanisms
The 30mm short stroke delivers rapid ejection of small finished parts from tight automated tooling spaces.
Replacing the Airtac SI32 Standard Air Cylinder SI32X30S with the SAI32X30S
To replace the SI32X30S, order the SAI32X30S. Confirm the ISO 15552 mounting interface, 32mm bore, 30mm stroke, G1/8 port (PT/G/NPT), and mounting accessory. The -S denotes a piston magnet for CS1-B/DS1-B sensors. Sizing both ways: the 32mm bore yields 402N push at 0.5MPa, while a neighbouring 40mm bore yields 628N. A plain cylinder drifts on air loss, so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. The 30mm stroke is very short, so side-load risks are minimal.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X30S
- ✓ 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 SI32X30S FAQ
Yes, the AirTAC SI32X30S is discontinued. The direct replacement is the SAI32X30S. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 30mm stroke, 402N force, G1/8 port, and mounting fixtures.
The 32mm bore uses a G1/8 port. It generates 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and 724N push at 0.9MPa. The theoretical maximum force is 82kgf at 1.0MPa.
