This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX240S, 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 SI32AX240S
The AirTAC SI32 Standard Air Cylinder SI32AX240S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 240mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX240S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX240S
The AirTAC SI32AX240S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 240mm stroke. It delivers 402N push force at 0.5MPa through a G1/8 port. The direct replacement is the SAI32AX240S, which matches the original bore, stroke, force, and mounting fixtures.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SI32AX240S features a SUS420J2 stainless rod and a piston magnet for CS1-B/DS1-B switches.

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 SI32AX240S Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably push lightweight machined components out of a fixture.
Package Diverting
Actuates a diverting arm along the 240mm stroke to sort small boxes on a manufacturing line.
Gripper Actuation
Drives a small parallel gripper to hold and release parts, utilizing the SUS420J2 stainless rod.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX240S with the SAI32AX240S
To replace the SI32AX240S, order the SAI32AX240S. Verify the ISO 15552 mounting interface, 240mm stroke, G1/8 port, and the -S magnet for legacy CS1-B/DS1-B sensors (the SAI uses current AirTAC switches). The -A suffix denotes the SUS420J2 stainless rod. If you need more force, the neighbouring 40mm bore offers 628N push at 0.5MPa; if less is required, check smaller profiles. Because stroke is 240mm, ensure guide alignment to prevent rod bending under side loads. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX240S
- ✓ 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 SI32AX240S FAQ
Yes, the SI32AX240S is discontinued. The direct replacement is the SAI32AX240S. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 240mm stroke, G1/8 port, and mounting interface.
It has a G1/8 port. The force ratings are: 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.
