This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X16, 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 SI32X16
The AirTAC SI32 Standard Air Cylinder SI32X16 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 16mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X16, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X16
The AirTAC SI32X16 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 16mm stroke, delivering 402N push force at 0.5MPa via a G1/8 port. As this stroke is nonstandard, the direct replacement is the SAI32X16, which matches the interface, force and mounting exactly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this no-S SKU cannot take a sensor; legacy -S types used 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 SI32X16 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to eject small molded parts from a fixture quickly.
Clamp Actuation
Short 16mm stroke provides rapid clamping pressure for lightweight material holding.
Gate Diverting
Pivots small diverters in packaging lines where a compact 32mm bore is required.
Replacing the Airtac SI32 Standard Air Cylinder SI32X16 with the SAI32X16
To replace the SI32X16, order the SAI32X16. Confirm the ISO 15552 mounting interface, 32mm bore, 16mm nonstandard stroke, G1/8 port (PT/G/NPT thread options) and mounting accessory. For sizing both ways: a 40mm bore yields 628N push at 0.5MPa, while dropping to a smaller bore reduces force. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external pilot check valve or the SAIL/BSAI lock variants. The SAIF variant adds a built-in valve. For any stroke >=300mm, add external guides to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X16
- ✓ 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 SI32X16 FAQ
Yes, the SI32X16 is discontinued. The direct replacement is the SAI32X16. It is dimensionally interchangeable per ISO 15552, keeping the same 32mm bore, 16mm stroke, force and G1/8 port.
The 32mm bore uses a G1/8 port. It generates 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa.
