This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the drop-in replacement SAI32BX700S, 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 SI32BX700S
The AirTAC Airtac SI32 Standard Air Cylinder SI32BX700S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 700mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAI32BX700S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX700S
The AirTAC SI32BX700S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore, 700mm stroke, SUS304 stainless rod and piston magnet. It delivers 402N push at 0.5MPa via a G1/8 port. AirTAC replaced it with the SAI32BX700S, a drop-in replacement retaining the same interface, force and mounting.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. For this bore, safe working load is roughly 241N (60% of 402N) and vertical lift is about 20kg with a 2:1 margin. The SAI family also adds SAIL, SAIF and BSAI lock 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 SI32BX700S Is Used
Stainless Rod Actuation
Ideal for packaging equipment needing corrosion resistance, using the SUS304 rod to push light 20kg vertical loads over a 700mm travel distance.
Long Stroke Diversion
Suitable for diverting small parts on a conveyor line, where the 402N push force at 0.5MPa easily moves items across a 700mm span.
Compact Material Handling
Fits automated warehouse routing gates requiring a 32mm bore, providing reliable 345N pull force within tight spatial constraints.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX700S with the SAI32BX700S
To replace the SI32BX700S, order the SAI32BX700S. Confirm the ISO 15552 mounting interface, 32mm bore, 700mm stroke, G1/8 port, SUS304 rod and magnet for CS1-B/DS1-B switches. At 700mm, prevent rod bending by adding external guides to absorb side loads. For sizing, the 40mm bore yields 628N push at 0.5MPa if more force is needed, while the 32mm bore is optimal for lighter loads. Plain cylinders drift on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX700S
- ✓ 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 SI32BX700S FAQ
Yes, the SI32BX700S is discontinued. The exact drop-in replacement is the SAI32BX700S. It is dimensionally interchangeable per ISO 15552, keeping the same 32mm bore, 700mm stroke, G1/8 port and mounting interface.
This 32mm bore double-acting cylinder uses a G1/8 port. It 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.
