This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X205, 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 SI32X205
The AirTAC SI32 Standard Air Cylinder SI32X205 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 205mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X205, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X205
The AirTAC SI32X205 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 205 mm stroke. It delivers 402 N push force at 0.5 MPa via a G1/8 port. Because the SI line is end-of-life, you should order the direct replacement: the SAI32X205. It shares the same ISO 15552 mounting interface, bore, stroke, output force, port size and accessories, fitting existing fixtures perfectly.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note this non-magnet SKU cannot take a sensor; legacy -S versions used CS1-B/DS1-B switches. The SAI family also 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 SI32X205 Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture using its 402 N push force at 0.5 MPa.
Package Diverting
Actuates a routing gate on a 30-800 mm/s conveyor line to sort small boxes without overwhelming the mechanism.
Clamp Actuation
Provides reliable clamping pressure for thin-gauge material holding in automated assembly cells.
Replacing the Airtac SI32 Standard Air Cylinder SI32X205 with the SAI32X205
To replace the SI32X205, order the SAI32X205. Confirm the ISO 15552 mounting interface (LB foot, FA/FB flange, CA/CB clevis or TC trunnion), the 205 mm stroke, and the G1/8 port (available in PT, G or NPT threads). This non-magnet model cannot accept a sensor; if position detection is needed, select an SAI32X205S and use current AirTAC switches. For sizing both ways, a 40 mm bore offers 628 N push at 0.5 MPa, while dropping to a 25 mm bore reduces force. Remember a plain cylinder does not hold load without live air; the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variant. At 205 mm stroke, side-load is minimal, but ensure guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X205
- ✓ 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 SI32X205 FAQ
Yes, the SI32X205 is discontinued. The direct replacement is the AirTAC SAI32X205. It is dimensionally interchangeable per ISO 15552, matching the 32 mm bore, 205 mm stroke, output force, G1/8 port and mounting interface.
This 32 mm bore cylinder uses a G1/8 port. It generates 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa. It operates at 30-800 mm/s.
