This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX300S, 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 SI32AX300S
The AirTAC SI32 Standard Air Cylinder SI32AX300S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 300mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX300S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX300S
The AirTAC SI32AX300S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore, 300mm stroke, and SUS420J2 stainless rod. Delivering 402N push at 0.5MPa, it is replaced by the SAI32AX300S. This direct upgrade keeps the same G1/8 port, M10x1.25 thread, and mounting interface.
The SAI features an upgraded two Y-shaped one-way piston seal for low start-up pressure. The -S magnet works with CS1-B/DS1-B sensors. For air-loss holding, use SAIL/BSAI locks, as cushions only decelerate.

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 SI32AX300S Is Used
Compact Actuation
Drives small 241N working load mechanisms like part diverters and lightweight grippers on machinery.
Transfer Pushers
Pushes light components between conveyor belts with a 300mm reach, requiring guide support.
Lab Automation
Actuates testing fixtures and sample handlers where the SUS420J2 stainless rod resists corrosion.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX300S with the SAI32AX300S
To replace the SI32AX300S, order the SAI32AX300S. Verify the ISO 15552 interface, 32mm bore, 300mm stroke, G1/8 port, and mounting. The -S magnet enables CS1-B/DS1-B sensors (SAI uses current switches), and -A denotes the SUS420J2 rod. For higher force, the 40mm bore yields 628N push at 0.5MPa. At 300mm stroke, use external guides to prevent rod bending. Cushions only decelerate; for load holding, use SAIL/BSAI locks or a pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX300S
- ✓ 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 SI32AX300S FAQ
Yes, the SI32AX300S is discontinued. The direct replacement is the SAI32AX300S, offering the same ISO 15552 mounting interface, 32mm bore, 300mm stroke, force, and G1/8 port.
It has a G1/8 port. Force ratings are 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa.
