This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX600, 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 SI32AX600
The AirTAC SI32 Standard Air Cylinder SI32AX600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 600mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX600
The AirTAC SI32AX600 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 600mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. AirTAC replaced this legacy unit with the SAI32AX600, a direct sharing the exact ISO 15552 mounting interface, bore, stroke, force, and port.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This specific SKU uses a SUS420J2 stainless rod (A) and lacks a magnet, so it cannot take CS1-B/DS1-B sensors. Note that plain cylinders drift without air; use SAIL or BSAI lock variants for load holding.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32AX600 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32AX600 Is Used
Light-Part Ejection
Pushes small molded parts off a conveyor belt using 402N of force, though external guides are required to support the 600mm stroke.
Package Diverting
Diverts lightweight cartons on a sorting line where the 345N pull force easily retracts the 12mm rod over the long 600mm travel.
Material Transfer
Moves light workpieces between stations, utilizing the SUS420J2 stainless rod to resist moisture in washdown-adjacent areas.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX600 with the SAI32AX600
To replace the SI32AX600, order the SAI32AX600. Confirm the ISO 15552 mounting interface, the G1/8 port, and your mounting accessory (LB, FA, TC). This SKU lacks a magnet, so it cannot accept position sensors; if sensing is needed, order an SAI with the S suffix. At 0.5MPa, push is 402N and pull is 345N; if you need less force, step down to a 25mm bore, or step up to 40mm (628N) for more power. Because the 600mm stroke is long, use an external guide to prevent rod bending and side loads. The cushion only decelerates; for load holding on air loss, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX600
- ✓ 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 SI32AX600 FAQ
Yes, the SI32AX600 is discontinued. The direct replacement is the SAI32AX600. It shares the exact ISO 15552 mounting interface, 32mm bore, 600mm stroke, force, and G1/8 port, so it drops into existing fixtures without modification.
It has a G1/8 port. Force output is 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical maximum of 82kgf at 1.0MPa. It operates at 30-800mm/s.
