This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X350TC, 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 SI32X350TC
The AirTAC SI32 Standard Air Cylinder SI32X350TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 350mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X350TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X350TC
The AirTAC SI32X350TC is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 350mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X350TC. This direct successor retains the exact TC trunnion mounting interface, bore, stroke, output force, and port size for seamless fixture integration.
The SAI upgrade features a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. For load holding, note that a plain cylinder drifts on air loss; the cushion only decelerates. Use a pilot check valve or the SAIL/BSAI lock variants. This SKU lacks a magnet, so it cannot accept a CS1-B/DS1-B 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 SI32X350TC Is Used
Package Diversion
Actuates lightweight routing gates on packaging lines, utilizing the 402N push force to deflect cartons at high cycling speeds.
Small Part Ejection
Provides the 350mm reach needed to push completed components out of CNC machining envelopes into collection bins.
Replacing the Airtac SI32 Standard Air Cylinder SI32X350TC with the SAI32X350TC
To replace the SI32X350TC, order the SAI32X350TC. Verify the ISO 15552 TC trunnion mount, 32mm bore, 350mm stroke, and G1/8 port (PT/G/NPT thread options). Because this SKU lacks the -S magnet, it cannot support position sensing; if switches are needed, select an SAI32X350TCS. Sizing both ways: a 40mm bore offers 628N push at 0.5MPa, while dropping to 25mm yields less force. At 350mm, the stroke is long relative to the 12mm rod, so use external guides to prevent rod bending and side-load damage. For load holding on air loss, add an external rod lock or pilot check valve, or specify the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X350TC
- ✓ 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 SI32X350TC FAQ
Yes, the SI32X350TC is discontinued. The direct replacement is the SAI32X350TC. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 350mm stroke, TC mount, G1/8 port, and output force, so it fits existing fixtures directly.
This double-acting 32mm bore cylinder features a G1/8 air port. It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical maximum of 82kgf at 1.0MPa.
