This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32BX110S, 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 SI32BX110S
The AirTAC SI32 Standard Air Cylinder SI32BX110S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 110mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32BX110S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX110S
The AirTAC SI32BX110S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore, 110mm stroke, and SUS304 stainless steel rod. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32BX110S. This direct successor matches the exact interface, bore, stroke, force, and mounting hardware.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The original -S magnet supports legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL lock and SAIF valve variants the SI lacked.

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 SI32BX110S Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably push lightweight molded parts out of an injection mold fixture.
Package Diverting
The 110mm stroke actuates a diverter arm to route small boxes on a packaging line without占用 excessive space.
Lab Test Fixtures
The SUS304 stainless rod provides corrosion resistance for clamping test samples in humid or chemical laboratory environments.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX110S with the SAI32BX110S
To replace the SI32BX110S, order the SAI32BX110S and confirm the ISO 15552 mounting interface, 32mm bore, 110mm stroke, G1/8 port, and your specific mounting accessory. The -B rod is SUS304 stainless steel, and the -S magnet works with legacy CS1-B/DS1-B switches (the SAI uses current AirTAC switches). For sizing both ways: a 40mm bore offers 628N push at 0.5MPa, while dropping to 0.3MPa on this 32mm bore yields 241N. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 110mm stroke, side-load is minimal, but always guide the load to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX110S
- ✓ 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 SI32BX110S FAQ
Yes, the SI32BX110S is discontinued. The direct replacement is the SAI32BX110S. It is dimensionally interchangeable per ISO 15552, maintaining the same 32mm bore, 110mm stroke, G1/8 port, and mounting interface for a direct fixture fit.
The bore is 32mm with a G1/8 air port. The thrust is 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.
