This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X330, 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 SI32X330
The AirTAC SI32 Standard Air Cylinder SI32X330 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 330mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X330, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X330
The AirTAC SI32X330 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 330mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X330. This direct successor matches the exact ISO 15552 mounting interface, bore, stroke, output force, and port size, fitting existing fixtures perfectly.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note this SKU lacks a magnet (-S) and cannot accept a sensor; the legacy SI used CS1-B/DS1-B switches. For load holding, the SAIL or BSAI lock variants are required, as cushions only decelerate.

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 SI32X330 Is Used
Light-Part Ejection
Ideal for pushing small machined components out of a fixture, utilizing the 402N push force at 0.5 MPa without damaging the part surface.
Package Diverting
The 330mm stroke provides ample travel to actuate a diverter arm on a packaging line, sorting lightweight boxes at speeds up to 800 mm/s.
Small Tray Positioning
Moves empty pallets or trays into a loading station, where the 20kg vertical lift capacity easily handles the transfer mechanics.
Replacing the Airtac SI32 Standard Air Cylinder SI32X330 with the SAI32X330
To replace the SI32X330, order the SAI32X330, confirming the ISO 15552 interface, 32mm bore, 330mm stroke, G1/8 port (PT/G/NPT), and mounting accessory. This non-magnet SKU cannot take a sensor; if sensing is needed, specify the -S magnet on the SAI. Because the 330mm stroke exceeds 300mm, use an external guide to prevent rod bending and side-load wear. A plain cylinder drifts on air loss; for held loads, use the SAIL air-released lock, BSAI clamp-lock, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X330
- ✓ 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 SI32X330 FAQ
Yes, the SI32X330 is discontinued. The direct replacement is the AirTAC SAI32X330. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 330mm stroke, output force, G1/8 port, and mounting interface.
The 32mm bore features a G1/8 air port and M10x1.25 rod thread. It delivers a push force of 402N and pull of 345N at 0.5MPa, 563N push at 0.7MPa, 724N at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa.
