This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X350SH, 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 SI32X350SH
The AirTAC SI32 Standard Air Cylinder SI32X350SH 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 SAI32X350SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X350SH
The AirTAC SI32X350SH is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 350 mm stroke. Generating 402 N push force at 0.5 MPa, it is replaced directly by the SAI32X350SH. The SAI direct keeps the same G1/8 port, M10x1.25 thread, and ISO 15552 mounting interface for existing fixtures.
The SAI upgrade features a new piston seal with two Y-shaped elements for low start-up pressure and long life. This -S model has a magnet for CS1-B/DS1-B sensors, while the -H option specifies Viton seals for 0-150 C heat.

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 SI32X350SH Is Used
Small Parts Ejection
Provides 402 N of push force at 0.5 MPa to eject machined components from fixtures, utilizing the 350 mm stroke for extended reach.
High-Temp Sorting
The Viton H seal option allows operation up to 150 C, making it suitable for diverting parts near drying ovens.
Replacing the Airtac SI32 Standard Air Cylinder SI32X350SH with the SAI32X350SH
To replace this SI32X350SH, order the SAI32X350SH direct, confirming the ISO 15552 interface, 32 mm bore, 350 mm stroke, G1/8 port, and magnet. If you need more force, the neighboring 40 mm bore yields 628 N push at 0.5 MPa; if less is acceptable, consider smaller profiles. Because this is a 350 mm stroke, use external guides to prevent rod bending and side-load wear. A plain cylinder does not hold load without live air—the cushion only decelerates—so use an external rod lock or pilot check valve for holding, or step up to the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X350SH
- ✓ 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 SI32X350SH FAQ
Yes, the SI32X350SH is discontinued. The direct replacement is the SAI32X350SH. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 350 mm stroke, force, G1/8 port, and mounting accessories.
The 32 mm bore uses a G1/8 port. Forces are 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa. Speed is 30-800 mm/s.
