This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X210, 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 SI32X210
The AirTAC SI32 Standard Air Cylinder SI32X210 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 210mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X210, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X210
The AirTAC SI32X210 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 210mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X210. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, force, port and mounting accessories.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This no-magnet SKU cannot take a sensor; legacy -S versions used CS1-B/DS1-B switches. For high heat, Viton H seals raise the temperature limit 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 SI32X210 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to eject small machined components from a fixture without damaging the surface.
Package Diverting
Actuates a lightweight diverter arm over 210mm to sort small boxes on a line, fitting within standard ISO 15552 footprint.
Replacing the Airtac SI32 Standard Air Cylinder SI32X210 with the SAI32X210
To replace the SI32X210, order the SAI32X210 keeping the same 32mm bore, 210mm stroke, G1/8 port and ISO 15552 mounting. Confirm your thread standard (PT/G/NPT) and accessory type (LB, FA, TC, etc). This SKU lacks the -S magnet, so it cannot accept a position sensor; order the -S version if you need CS1-B/DS1-B switches. For sizing, the 40mm neighbor bore yields 628N push at 0.5MPa, while dropping to 25mm stroke saves space without losing the 402N force. At 210mm stroke, guide the load to prevent rod bending and side-load wear. 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. The SAIF variant adds a built-in 4M valve (bores 32-100).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X210
- ✓ 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 SI32X210 FAQ
Yes, the AirTAC SI32X210 is discontinued. The direct replacement is the SAI32X210. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 210mm stroke, 402N force, G1/8 port and mounting interface.
The 32mm bore features a G1/8 port and M10x1.25 rod thread. Force output is 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. Speed is 30-800 mm/s.
