This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX175, 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 SI32AX175
The AirTAC SI32 Standard Air Cylinder SI32AX175 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 175mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX175, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX175
The AirTAC SI32AX175 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 175mm stroke. It delivers 402N push force at 0.5MPa through a G1/8 port. The direct replacement is the SAI32AX175, which matches the exact bore, stroke, force, port, and ISO 15552 mounting interface.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This SKU uses a SUS420J2 stainless steel rod (A option) and lacks a magnet, so it cannot take a sensor.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32AX175 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 SI32AX175 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably knock small molded parts out of a fixture without damaging components.
Package Diverting
Actuates a lightweight diverter arm on a packaging line, where the 175mm stroke provides exact routing distance.
Corrosive Handling
Leverages the SUS420J2 stainless rod for light-duty clamping in humid or mildly corrosive manufacturing environments.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX175 with the SAI32AX175
To replace the SI32AX175, order the SAI32AX175 and confirm the ISO 15552 interface, 32mm bore, 175mm stroke, G1/8 port, and SUS420J2 rod. This non-magnet SKU cannot accept a switch. For higher loads, a 40mm bore yields 628N push at 0.5MPa. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variant. At 175mm stroke, guide external rods to prevent side-load bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX175
- ✓ 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 SI32AX175 FAQ
Yes, the SI32AX175 is discontinued. The direct replacement is the SAI32AX175. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 175mm stroke, output force, G1/8 port, and mounting accessories.
This double-acting cylinder uses a G1/8 port. It delivers a push force of 402N and a pull force of 345N at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical maximum of 82kgf at 1.0MPa.
