This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX195S, 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 SI32AX195S
The AirTAC SI32 Standard Air Cylinder SI32AX195S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 195mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX195S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX195S
The AirTAC SI32AX195S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore, 195mm stroke, and SUS420J2 stainless steel rod. Delivering 402N push at 0.5MPa via a G1/8 port, it is replaced by the SAI32AX195S. This direct upgrade matches the bore, stroke, force, and mounting interface, fitting existing fixtures perfectly.
The SAI features an upgraded piston seal with two Y-shaped elements for low start-up pressure and long life. The -S magnet works with legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL lock, SAIF valve, and BSAI clamp-lock variants.

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 SI32AX195S Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably eject small machined components from a fixture without damaging the surface.
Package Diverting
Actuates a lightweight diverter arm on a packaging line, where the 20kg vertical lift capacity handles standard routing tasks easily.
Lab Test Positioning
Moves sample trays into testing position, benefiting from the SUS420J2 stainless rod for corrosion resistance in humid environments.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX195S with the SAI32AX195S
To replace the SI32AX195S, order the SAI32AX195S. Verify the ISO 15552 mounting interface, 32mm bore, 195mm stroke, G1/8 port, and your specific mounting accessory. The -A denotes a SUS420J2 stainless rod, and -S indicates a magnet for CS1-B/DS1-B switches; the SAI uses current AirTAC switches. If sizing up, a 40mm bore yields 628N push at 0.5MPa; sizing down is not available below 32mm. A plain cylinder drifts on air loss, as the 27mm cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. At 195mm stroke, side-load is minimal, but ensure guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX195S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
