This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X900, 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 SI32X900
The AirTAC SI32 Standard Air Cylinder SI32X900 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 900mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X900, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X900
The AirTAC SI32X900 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 900mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X900. This direct successor matches the exact interface, bore, stroke, force, and mounting of the original.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SI line lacked SAIL, SAIF, and BSAI lock variants now available. With no -S magnet, this SKU cannot take a sensor (legacy types used CS1-B/DS1-B). A 900mm stroke requires external guides to prevent rod bending.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X900 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 SI32X900 Is Used
Long-Stroke Diversion
Pushes lightweight packages across a 900mm conveyor lane using the 402N push force at 0.5MPa, guided externally to prevent rod bending.
Compact Assembly Ejection
Ejects small parts over a long 900mm distance from a compact ISO 15552 fixture using the 32mm bore and M10x1.25 rod thread.
Replacing the Airtac SI32 Standard Air Cylinder SI32X900 with the SAI32X900
To replace the SI32X900, order the SAI32X900. Confirm the ISO 15552 mounting interface, 32mm bore, 900mm stroke, G1/8 port (PT/G/NPT thread options), and mounting accessory (LB, FA, TC, etc.). This SKU lacks a magnet (-S) and cannot accept a sensor. Because 900mm exceeds 300mm, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X900
- ✓ 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 SI32X900 FAQ
Yes, the SI32X900 is discontinued. The direct replacement is the AirTAC SAI32X900. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 900mm stroke, 402N force, G1/8 port, and mounting interface.
This double-acting cylinder has a 12mm rod, M10x1.25 thread, 27mm cushion, and operates at 30-800 mm/s. Force ratings are: push 402N and pull 345N at 0.5MPa, push 563N at 0.7MPa, push 724N at 0.9MPa, and a theoretical max of 82 kgf at 1.0MPa.
