This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X330S, 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 SI32X330S
The AirTAC SI32 Standard Air Cylinder SI32X330S 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 SAI32X330S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X330S
The AirTAC SI32X330S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 330mm stroke, delivering 402N push force at 0.5MPa. The direct replacement is the SAI32X330S, matching the bore, stroke, G1/8 port, and ISO 15552 mounting interface.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The -S suffix means it has a piston magnet for 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 SI32X330S Is Used
Small Parts Ejection
Ideal for pushing light machined components out of fixtures using its 402N push force at 0.5MPa.
Package Diverting
The 330mm stroke actuates diverter arms on packaging lines to route small boxes efficiently.
Replacing the Airtac SI32 Standard Air Cylinder SI32X330S with the SAI32X330S
To replace the SI32X330S, order the SAI32X330S, confirming the ISO 15552 interface, G1/8 port, and mounting accessory. The 330mm stroke exceeds 300mm, so use an external guide to prevent rod bending and side loads. If you need more force, the 40mm bore yields 628N at 0.5MPa. For load holding on air loss, note that standard cylinders drift; use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The SAIF variant adds a built-in valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X330S
- ✓ 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 SI32X330S FAQ
Yes, the SI32X330S is discontinued. The direct replacement is the SAI32X330S, which shares the same ISO 15552 mounting interface, 32mm bore, 330mm stroke, and G1/8 port.
The 32mm bore has a G1/8 port. It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a maximum theoretical force of 82kgf at 1.0MPa.
