This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32BX170S, 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 SI32BX170S
The AirTAC SI32 Standard Air Cylinder SI32BX170S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 170mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32BX170S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX170S
The AirTAC SI32BX170S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 170mm stroke. Providing 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32BX170S. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, force, port and mounting accessories.
The SAI32BX170S features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This specific -B variant uses a SUS304 stainless piston rod for corrosion resistance. The built-in magnet supports legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL, SAIF and BSAI 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 SI32BX170S Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture using the 402N push force at 0.5MPa.
Material Diverting
Actuates low-friction diverter gates on conveyor lines, benefiting from the 30-800mm/s speed range.
Lab Test Actuators
The SUS304 stainless rod provides corrosion resistance for repetitive testing in humid environments.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX170S with the SAI32BX170S
To replace the SI32BX170S, order the SAI32BX170S ensuring the ISO 15552 interface, 32mm bore, 170mm stroke, G1/8 port and SUS304 rod are matched. Confirm your mounting accessory (LB, FA, TC, etc.) and the -S magnet requirement. For sizing both ways, neighbouring bores like 40mm offer 628N push at 0.5MPa if more force is needed. Remember a plain cylinder does not hold load on air loss; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. As the stroke is under 300mm, side-load rod-bending is minimal, but standard guide alignment checks apply.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX170S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
