This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the drop-in replacement SAI32BX800S, 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 SI32BX800S
The AirTAC Airtac SI32 Standard Air Cylinder SI32BX800S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 800mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAI32BX800S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX800S
The AirTAC SI32BX800S is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore, 800 mm stroke, and a SUS304 stainless steel rod. Generating 402 N push force at 0.5 MPa, it is replaced by the SAI32BX800S. This drop-in upgrade shares the same ISO 15552 mounting interface, G1/8 port, and stroke. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
With a 12 mm rod and M10x1.25 thread, this unit includes a magnet for CS1-B/DS1-B sensors. A computed buyer insight: safe working load is ~241 N (60% of 402 N), yielding a ~20 kg vertical lift with a 2:1 margin. For higher temperatures, Viton H seals raise the limit to 150 C.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32BX800S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI32BX800S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32BX800S Is Used
Long-Stroke Diversion
Pushes lightweight packages across a transfer line with its 800 mm reach, relying on the SUS304 rod for corrosion resistance in washdown zones.
Compact Ejection
Ejects small machined parts from a fixture using 402 N of push force at 0.5 MPa, fitting neatly within standard ISO 15552 tooling plates.
Vertical Lifting
Raises 20 kg tote boxes vertically using a 2:1 safety margin on the 0.5 MPa thrust, requiring external guides to stabilize the extended rod.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX800S with the SAI32BX800S
To replace the SI32BX800S, order the SAI32BX800S. Confirm the ISO 15552 interface, 32 mm bore, 800 mm stroke, G1/8 port, and SUS304 rod. The -S magnet enables current AirTAC switches (legacy used CS1-B/DS1-B). For sizing, the 40 mm bore offers 628 N push at 0.5 MPa if more force is needed, while the 32 mm bore is optimal for lighter loads. A plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external rod lock or pilot check valve, or specify the SAIL or BSAI lock variant. At 800 mm stroke, prevent rod bending by using an external guide to handle side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX800S
- ✓ 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 SI32BX800S FAQ
Yes, the SI32BX800S is discontinued. The exact drop-in replacement is the SAI32BX800S. It shares the same ISO 15552 mounting interface, 32 mm bore, 800 mm stroke, G1/8 port, and force, fitting existing fixtures directly.
The 32 mm bore uses a G1/8 port. Force output is 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. It operates at 30-800 mm/s.
