This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X750S, 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 SI32X750S
The AirTAC SI32 Standard Air Cylinder SI32X750S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 750mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X750S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X750S
The AirTAC SI32X750S is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 750 mm stroke. It delivers 402 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAI32X750S, a direct replacement retaining the exact ISO 15552 mounting interface, M10x1.25 rod thread, G1/8 port, and output force so it fits existing fixtures.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. You can also specify Viton H seals for high-temperature duties, and the -S magnet on this SKU supports legacy CS1-B/DS1-B sensors.

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 SI32X750S Is Used
Long-Stroke Diversion
Pushes light packages across a 750 mm conveyor lane using the 402 N push force, requiring external guides to prevent rod bending.
Compact Ejection
Ejects small parts from tight fixtures using the 32 mm profile barrel and G1/8 port, fitting neatly into existing ISO 15552 mounts.
Replacing the Airtac SI32 Standard Air Cylinder SI32X750S with the SAI32X750S
To replace the SI32X750S, order the SAI32X750S and confirm the ISO 15552 mounting interface, 32 mm bore, 750 mm stroke, G1/8 port (PT/G/NPT thread options), and your mounting accessory. The -S suffix means a piston magnet is present for CS1-B/DS1-B switches; if you need self-contained valves, the SAIF variant (bores 32-100) integrates a 4M valve. For sizing both ways, a 40 mm bore gives 628 N push at 0.5 MPa, while dropping to a 25 mm bore reduces force. Note that a 750 mm stroke invites rod bending under side-load, so use an external guide. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X750S
- ✓ 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 SI32X750S FAQ
Yes, the SI32X750S is discontinued. The direct replacement is the AirTAC SAI32X750S. It shares the same ISO 15552 mounting interface, 32 mm bore, 750 mm stroke, G1/8 port, and force ratings, fitting directly into your existing fixtures.
The 32 mm bore uses a G1/8 air port. At 0.5 MPa it provides 402 N push and 345 N pull force. At 0.7 MPa push is 563 N, and at 0.9 MPa it is 724 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
