This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX900, 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 SI32AX900
The AirTAC SI32 Standard Air Cylinder SI32AX900 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 SAI32AX900, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX900
The AirTAC SI32AX900 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 900mm stroke. Generating 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32AX900. This direct successor shares the exact ISO 15552 mounting interface, bore, stroke and output force, fitting existing fixtures perfectly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU lacks a magnet (-S) and cannot take a sensor, unlike legacy CS1-B/DS1-B switches. The -A code specifies a SUS420J2 stainless rod.

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 SI32AX900 Is Used
Light-Part Ejection
Uses the 402N push force to sweep small molded parts off a conveyor line over the 900mm travel distance.
Carton Diverting
Actuates a diverting arm in packaging zones, moving light cardboard boxes without needing a magnet sensor.
Test Fixture Slide
Drives a lightweight testing carriage across a 900mm span, relying on the SUS420J2 stainless rod for corrosion resistance.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX900 with the SAI32AX900
To replace the SI32AX900, order the SAI32AX900, confirming the ISO 15552 interface, 32mm bore, 900mm stroke, G1/8 port, and SUS420J2 rod. Since this lacks -S, it cannot accept a sensor. If sizing up or down, check the 40mm bore (628N push @0.5MPa) or 25mm options. For load holding on air loss, the cushion only decelerates; use an external pilot check valve or the SAIL/BSAI lock variant. At 900mm, prevent rod bending by using an external guide to manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX900
- ✓ 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 SI32AX900 FAQ
Yes, the SI32AX900 is discontinued. The direct replacement is the SAI32AX900. It shares the identical ISO 15552 mounting interface, 32mm bore, 900mm stroke, force, and G1/8 port, fitting directly into your existing fixtures.
This 32mm bore cylinder features a G1/8 port, a 12mm rod, and 27mm cushions. It provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a maximum theoretical force of 82kgf at 1.0MPa.
