This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX65S, 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 SI32AX65S
The AirTAC SI32 Standard Air Cylinder SI32AX65S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 65mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX65S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX65S
The AirTAC SI32AX65S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 65mm stroke, delivering 402N push force at 0.5MPa. It featured a SUS420J2 stainless piston rod (-A) and a built-in magnet (-S) for CS1-B/DS1-B sensors. AirTAC replaced this legacy unit with the SAI32AX65S, a direct sharing the exact G1/8 port, M10x1.25 thread and mounting interface.
The SAI upgrade introduces a two-piece Y-shaped piston seal for low start-up pressure and extended life. If you need load holding on air loss, explore the SAIL or BSAI lock variants, as standard cushions only decelerate.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32AX65S 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 SAI32AX65S 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 SI32AX65S Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably push lightweight molded components out of a fixture on an assembly line.
Stainless Rod Clamping
The SUS420J2 (-A) rod provides corrosion resistance for clamping tasks in washdown or lightly humid manufacturing zones.
Sensor-Driven Sorting
The -S magnet enables CS1-B/DS1-B position detection for routing small products at 30-800mm/s within a conveyor gate.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX65S with the SAI32AX65S
To replace the SI32AX65S, order the SAI32AX65S and confirm the ISO 15552 mounting interface, 65mm stroke, G1/8 port, and -S magnet for current AirTAC switches. The -A rod denotes SUS420J2 stainless steel; specify this on the SAI if corrosion resistance is needed. For sizing, this 32mm bore yields 402N push at 0.5MPa; dropping to a 25mm bore cuts force, while a 40mm bore offers 628N. Remember, a standard cylinder drifts without air; for load holding, use an external pilot check valve or the SAIL lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX65S
- ✓ 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 SI32AX65S FAQ
Yes, the AirTAC SI32AX65S is discontinued. The direct replacement is the SAI32AX65S. It shares the same ISO 15552 mounting interface, 32mm bore, 65mm stroke, output force, G1/8 port, and -S magnet, fitting existing fixtures perfectly.
The G1/8 port bore delivers a push force of 402N and pull of 345N at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa.
