This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX375, 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 SI32AX375
The AirTAC SI32 Standard Air Cylinder SI32AX375 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 375mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX375, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX375
The AirTAC SI32AX375 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 375mm stroke. Delivering 402N push at 0.5MPa via a G1/8 port, it is replaced by the SAI32AX375. This direct successor shares identical mounting, force, and stroke specs.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. This SKU lacks a magnet, so it cannot take a switch, and uses a SUS420J2 stainless rod. The cushion only decelerates; use SAIL or BSAI for load holding.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32AX375 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 | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32AX375 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 SI32AX375 Is Used
Light-Duty Ejection
Ideal for pushing small parts from a machining fixture using the 402N push force at 0.5MPa.
Package Diverting
Sort light cartons on a line where the 375mm stroke provides ample reach across the belt.
Lab Positioning
Moves test rigs or samples with the SUS420J2 stainless rod offering corrosion resistance.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX375 with the SAI32AX375
To replace the SI32AX375, order the SAI32AX375, confirming the ISO 15552 interface, 32mm bore, 375mm stroke, G1/8 port, and SUS420J2 rod. Since this has no -S magnet, it cannot accept CS1-B/DS1-B sensors. For higher force, a 40mm bore yields 628N push at 0.5MPa. The 375mm stroke requires external guides to prevent rod bending. The air cushion decelerates but does not hold; for dead-load locking, specify SAIL or BSAI.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX375
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
