This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X175N, 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 SI32X175N
The AirTAC SI32 Standard Air Cylinder SI32X175N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 175mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X175N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X175N
The AirTAC SI32X175N is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 175mm stroke. Delivering 402N push at 0.5MPa via a G1/8 port, it is replaced by the SAI32X175N. This direct successor shares the exact interface, force, and mounting.
The SAI upgrade features two Y-shaped piston seals for low start-up pressure. This SKU lacks a magnet, so it cannot take a sensor. The NBR seal suits -20 to +70C; Viton H extends this to 150C.

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 SI32X175N Is Used
Small Part Ejection
Uses the 402N push force to eject small molded parts from a fixture reliably.
Package Diverting
Actuates a diverter arm on a packaging line, fitting neatly within ISO 15552 mounts.
Light Clamping
Holds light workpieces in place during machining without over-stressing components.
Replacing the Airtac SI32 Standard Air Cylinder SI32X175N with the SAI32X175N
To replace the SI32X175N, order the SAI32X175N. Confirm the ISO 15552 mounting interface, 32mm bore, 175mm stroke, G1/8 port (PT/G/NPT), and mounting accessory. Because this SKU has no -S magnet, it cannot accept a CS1-B/DS1-B sensor. For sizing, the 32mm bore yields 402N push at 0.5MPa; dropping to a smaller bore reduces force, while a 40mm bore gives 628N. Air cushions only decelerate the load; for holding a load on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 175mm stroke, side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X175N
- ✓ 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 SI32X175N FAQ
Yes, the SI32X175N is discontinued. The direct replacement is the SAI32X175N. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 175mm stroke, force, G1/8 port, and mounting.
This double-acting cylinder has a G1/8 port. It provides 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.
