This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX300, 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 SI32AX300
The AirTAC SI32 Standard Air Cylinder SI32AX300 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 300mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX300, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX300
The AirTAC SI32AX300 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 300mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The direct replacement is the SAI32AX300, matching the bore, stroke, force, port and ISO 15552 mounting interface exactly.
The SAI32AX300 features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also adds SAIL, SAIF and BSAI variants the SI lacked. This SKU has a SUS420J2 stainless rod (-A) but no magnet, so it cannot take a sensor.

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 SI32AX300 Is Used
Small Parts Ejection
Uses the 402N push force at 0.5MPa to eject small machined components from a fixture cleanly without damaging the surface finish.
Package Diverting
Actuates a diverting gate on a 32mm bore line, where the 300mm stroke provides full travel to redirect lightweight cartons between parallel belts.
Lab Test Positioning
Moves sample trays into inspection stations, benefiting from the SUS420J2 stainless rod for corrosion resistance in humid or chemically exposed environments.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX300 with the SAI32AX300
To replace the SI32AX300, order the SAI32AX300. Confirm the ISO 15552 mounting interface, 32mm bore, 300mm stroke, G1/8 port and SUS420J2 rod. Because this SKU lacks a magnet (-S), it cannot accept CS1-B/DS1-B sensors; choose an SAI model with S if sensing is needed. For sizing, the 40mm bore offers higher force (628N push @0.5MPa), while the 32mm is more compact. At 300mm stroke, use external guides to prevent rod bending and side-load wear. The air cushion only decelerates; for load holding on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX300
- ✓ 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 SI32AX300 FAQ
Yes, the AirTAC SI32AX300 is discontinued. The direct replacement is the SAI32AX300. It is dimensionally interchangeable per ISO 15552, keeping the same 32mm bore, 300mm stroke, output force, G1/8 port and mounting accessories.
The G1/8 port bore delivers a push of 402N and pull of 345N at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa. Speed is 30-800mm/s.
