This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X15, 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 SI32X15
The AirTAC SI32 Standard Air Cylinder SI32X15 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 15mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X15, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X15
The AirTAC SI32X15 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 15mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The direct replacement is the SAI32X15, matching the interface, bore, stroke, force, port and mounting.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. This SKU lacks a magnet, so it cannot take a sensor. For high heat, Viton H seals raise the temp limit to 150C.

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 SI32X15 Is Used
Small Part Clamping
Ideal for holding light electronics components during machining, utilizing the 402N push force at 0.5MPa for secure, low-profile fixturing.
Short Stroke Ejection
The 15mm stroke provides rapid, compact ejection of small parts from automated assembly jigs without consuming excessive space.
Replacing the Airtac SI32 Standard Air Cylinder SI32X15 with the SAI32X15
To replace the SI32X15, order the SAI32X15. Verify your ISO 15552 mounting interface, G1/8 port, and M10x1.25 rod thread. Because this SKU has no -S magnet, it cannot accept CS1-B/DS1-B sensors. If you need more force, the neighboring 40mm bore gives 628N push at 0.5MPa; if less is acceptable, drop to a smaller profile. For load holding, note that a plain cylinder drifts on air loss—the cushion only decelerates. Use an external pilot check valve or the SAIL/BSAI lock variants. The SAIF variant integrates a 4M valve for bores 32-100.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X15
- ✓ 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 SI32X15 FAQ
Yes, the SI32X15 is discontinued. The direct replacement is the AirTAC SAI32X15. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 15mm stroke, 402N force, G1/8 port, and mounting interface.
This 32mm bore double-acting cylinder features a G1/8 air 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 force of 82kgf at 1.0MPa.
