This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X460, 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 SI32X460
The AirTAC SI32 Standard Air Cylinder SI32X460 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 460mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X460, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X460
The AirTAC SI32X460 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 460 mm stroke. Delivering 402 N push force at 0.5 MPa via a G1/8 port, it is replaced by the SAI32X460. This direct successor matches the exact ISO 15552 mounting interface, bore, stroke, force, port and mounting hardware.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life, while introducing SAIL, SAIF and BSAI variants the SI lacked. Note this SKU lacks a magnet, so it cannot accept 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 SI32X460 Is Used
Package Diverting
Suitable for pushing light cartons on a 460 mm stroke diverter arm where 402 N of push force at 0.5 MPa is sufficient.
Small Part Ejection
Deploys a 460 mm rod to eject molded components from a press, utilizing the 32 mm bore's compact footprint.
Replacing the Airtac SI32 Standard Air Cylinder SI32X460 with the SAI32X460
To replace the SI32X460, order the SAI32X460. Verify your ISO 15552 mounting interface (LB, FA, TC, etc.), the 460 mm stroke, and the G1/8 port (PT/G/NPT threads). Because this specific SKU has no -S magnet, it cannot support position sensing; order a magnet-equipped SAI32X460S if switches are required. At 0.5 MPa it yields 402 N push and 345 N pull; neighbouring bores like the 40 mm offer 628 N push if more force is needed. For the 460 mm stroke, use external guides to prevent rod bending and side-load damage. Plain cylinders drift on air loss; for load holding, use an external pilot check valve, rod lock, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X460
- ✓ 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 SI32X460 FAQ
Yes, the SI32X460 is discontinued. The direct replacement is the AirTAC SAI32X460. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 460 mm stroke, 402 N force, G1/8 port, and mounting interface.
At 0.5 MPa it provides 402 N push and 345 N pull; at 0.7 MPa it provides 563 N push; at 0.9 MPa it provides 724 N push; with a theoretical max of 82 kgf at 1.0 MPa. It operates at 30-800 mm/s, uses a G1/8 port, and accepts pressures from 0.15 to 1.0 MPa.
