This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX700, 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 SI32AX700
The AirTAC SI32 Standard Air Cylinder SI32AX700 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 700mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX700, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX700
The AirTAC SI32AX700 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 700mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The direct replacement is the SAI32AX700, featuring an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also uses a SUS420J2 stainless piston rod.
Because this SKU lacks a magnet, it cannot accept a position switch. Note the cushion only decelerates; it does not hold load on air loss.

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 SAI32AX700 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 SI32AX700 Is Used
Sample Diversion
Actuates a diverter arm in lab automation, relying on the SUS420J2 stainless rod for mild corrosion resistance.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX700 with the SAI32AX700
To replace the SI32AX700, order the SAI32AX700. Verify the ISO 15552 mounting interface, 32mm bore, 700mm stroke, G1/8 port, and SUS420J2 rod. This SKU has no magnet, so it cannot support sensing; the legacy CS1-B/DS1-B switches require a magnetic piston. For sizing, the 40mm bore offers higher force (628N push at 0.5MPa), while the 32mm provides 402N. At 700mm, prevent rod bending by using an external guide to absorb side loads. For load holding on air loss, use an external rod lock or pilot check valve, or specify the SAIL or BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX700
- ✓ 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 SI32AX700 FAQ
Yes, the SI32AX700 is discontinued. The direct replacement is the SAI32AX700. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 700mm stroke, force, G1/8 port, and mounting interface.
This double-acting cylinder uses a G1/8 port and provides 402N push / 345N pull at 0.5 MPa, 563N push at 0.7 MPa, 724N push at 0.9 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa.
