This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX30S, 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 SI32AX30S
The AirTAC SI32 Standard Air Cylinder SI32AX30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 30mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX30S
The AirTAC SI32AX30S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 30mm stroke. Featuring a SUS420J2 stainless piston rod (-A) and a built-in magnet (-S) for CS1-B/DS1-B legacy switches, it delivers 402N push force at 0.5MPa through a G1/8 port. AirTAC replaced this unit with the SAI32AX30S.
The SAI32AX30S is a direct replacement, matching the exact ISO 15552 mounting interface, bore, stroke, and force. The upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32AX30S 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 SAI32AX30S 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 SI32AX30S Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably kick small machined components out of a fixture on an assembly line.
Stainless Rod Clamping
The SUS420J2 stainless rod option provides corrosion resistance for clamping tasks in mildly wet or washdown environments.
Short Stroke Diverting
Ideal for compact 30mm stroke diverting gates where a G1/8 port and a 20kg safe vertical lift capacity are sufficient.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX30S with the SAI32AX30S
To replace the SI32AX30S, order the SAI32AX30S and confirm the ISO 15552 mounting interface, 32mm bore, 30mm stroke, G1/8 port, and magnet (-S) for current AirTAC switches. Sizing both ways: dropping to a smaller bore loses force, while stepping up to a 40mm bore increases the 0.5MPa push to 628N. This plain cylinder does not hold load without live air—the cushion only decelerates—so use an external rod lock or pilot check valve for holding, or specify an SAIL/BSAI lock variant. The -A rod provides SUS420J2 stainless corrosion resistance versus standard carbon steel.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX30S
- ✓ 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 SI32AX30S FAQ
Yes, the SI32AX30S is discontinued. The direct replacement is the SAI32AX30S. It shares the identical ISO 15552 mounting interface, 32mm bore, 30mm stroke, force, and G1/8 port, fitting existing fixtures perfectly while upgrading the piston seal.
The 32mm bore delivers 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. Operating speed is 30-800mm/s, with a 27mm adjustable air cushion at both ends.
