This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X480SN, 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 SI32X480SN
The AirTAC SI32 Standard Air Cylinder SI32X480SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 480mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X480SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X480SN
The AirTAC SI32X480SN is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 480mm stroke. It delivers 402N push and 345N pull at 0.5MPa via a G1/8 port. AirTAC replaced this legacy unit with the SAI32X480SN, a direct sharing the exact ISO 15552 mounting interface, bore, stroke, force and port. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The NBR seal handles -20 to +70C, with a Viton H option for high heat.
The -S magnet works with legacy CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches. The SAI family also adds SAIL, SAIF and BSAI lock variants absent in the SI line. Note that a 480mm stroke needs external guides to prevent rod bending.

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 SI32X480SN Is Used
Small Parts Ejection
Uses the 402N push force at 0.5MPa to eject light machined components from a fixture, relying on the adjustable 27mm air cushion to decelerate at the end of the 480mm travel.
Package Routing
Actuates a diverting arm along a packaging line; the 480mm stroke provides full lane clearance, while the G1/8 port delivers rapid 30-800mm/s cycling.
Replacing the Airtac SI32 Standard Air Cylinder SI32X480SN with the SAI32X480SN
To replace the SI32X480SN, order the SAI32X480SN. Verify the ISO 15552 mounting interface, 32mm bore, 480mm stroke, G1/8 port (PT/G/NPT thread), and mounting accessory. The -S magnet enables CS1-B/DS1-B sensors, while -N specifies the NBR seal. Because 480mm exceeds 300mm, add external guides to prevent rod bending and side-load wear. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X480SN
- ✓ 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 SI32X480SN FAQ
Yes, the AirTAC SI32X480SN is discontinued. The direct replacement is the SAI32X480SN. It shares the identical ISO 15552 mounting interface, 32mm bore, 480mm stroke, output force, G1/8 port, and accessories, fitting directly into existing fixtures.
The 32mm bore features a G1/8 air port and a 12mm rod. It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa. Operating speed is 30-800mm/s.
