This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X360, 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 SI32X360
The AirTAC SI32 Standard Air Cylinder SI32X360 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 360mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X360, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X360
The AirTAC SI32X360 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 360mm stroke. Delivering 402N push force at 0.5MPa, it is replaced by the SAI32X360. This direct successor shares the exact interface, G1/8 port, and M10x1.25 rod thread.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. Without a magnet, this SKU cannot take a sensor. For safe sizing, expect a 241N working load (60% of 402N) or a 20kg vertical lift. The SAI family adds SAIL and BSAI lock variants absent in the SI line.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X360 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SI32X360 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to push light machined components out of a fixture.
Package Diverting
The 360mm stroke actuates a diverter arm across a narrow belt line for sorting tasks.
Replacing the Airtac SI32 Standard Air Cylinder SI32X360 with the SAI32X360
To replace the SI32X360, order the SAI32X360, confirming the ISO 15552 mounting interface, 360mm stroke, and G1/8 port. Because this 360mm stroke exceeds 300mm, use an external guide to prevent rod bending and side-load wear. This non-magnet SKU cannot accept CS1-B/DS1-B sensors. If dropping to a 25mm bore yields insufficient force, step up to a 40mm bore. Note that a plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X360
- ✓ 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 SI32X360 FAQ
Yes, the SI32X360 is discontinued. The direct replacement is the SAI32X360. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 360mm stroke, output force, G1/8 port, and mounting accessories.
It features a G1/8 air port. Force output is 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.
