This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX110, 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 SI32AX110
The AirTAC SI32 Standard Air Cylinder SI32AX110 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 110mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX110, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX110
The AirTAC SI32AX110 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore, 110mm stroke, and a SUS420J2 stainless steel rod. Delivering 402 N push force at 0.5 MPa, it is replaced by the SAI32AX110. This direct successor shares the exact ISO 15552 mounting interface, bore, stroke, force, G1/8 port, and M10x1.25 thread.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note this SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32AX110 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 SI32AX110 Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to eject small molded components from machining fixtures reliably.
Corrosive Sorting
The SUS420J2 stainless rod handles humid or mildly corrosive environments while sorting light hardware.
Package Diverting
Provides a compact 110mm stroke to divert light packages on a conveyor without requiring full sensing.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX110 with the SAI32AX110
To replace the SI32AX110, order the SAI32AX110, confirming the ISO 15552 interface, 32mm bore, 110mm stroke, G1/8 port, and SUS420J2 rod. Because this SKU has no magnet, you cannot mount position sensors; order an -S variant if sensing is needed. For sizing, a 40mm bore offers 628 N push at 0.5 MPa, while dropping to a 25mm bore reduces force. The cushion only decelerates; it does not hold load. For dead-load holding on air loss, use an external pilot check valve or the SAIL/BSAI lock variants. At 110mm stroke, side-load risks are low, but ensure straight alignment to avoid rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX110
- ✓ 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 SI32AX110 FAQ
Yes, the SI32AX110 is discontinued. The direct replacement is the SAI32AX110, which shares the same ISO 15552 mounting interface, 32mm bore, 110mm stroke, output force, G1/8 port, and accessories.
It features a G1/8 port and M10x1.25 rod thread. Force output is 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa.
