This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X180, 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 SI32X180
The AirTAC SI32 Standard Air Cylinder SI32X180 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 180mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X180, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X180
The AirTAC SI32X180 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 180mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X180. This direct successor matches the exact mounting interface, bore, stroke, output force and accessories.
The SAI upgrade features a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Because this specific SI32X180 SKU lacks a magnet (-S), it cannot accept a CS1-B or DS1-B sensor.

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 SI32X180 Is Used
Package Diverting
Sort or deflect small cartons on a packaging line where a compact 32mm bore and 180mm stroke provide adequate reach.
Clamp Actuation
Secures low-mass workpieces during secondary machining operations, providing 402N of clamping thrust at 0.5MPa.
Replacing the Airtac SI32 Standard Air Cylinder SI32X180 with the SAI32X180
To replace the SI32X180, order the SAI32X180. Verify the ISO 15552 mounting interface (LB, FA, TC, etc.), the 180mm stroke, the G1/8 port, and the M10x1.25 rod thread. If your fixture requires position feedback, note this no-magnet SKU cannot hold a sensor; you must select an SAI32X180S instead. For sizing, neighbouring bores like 40mm offer 628N push at 0.5MPa if more force is needed. If holding a load vertically, remember the air cushion only decelerates; it does not lock. Use an external pilot check valve or explore the SAIL or BSAI lock variants. At 180mm stroke, side-load risks are low, but ensure proper rod alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X180
- ✓ 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 SI32X180 FAQ
Yes, the SI32X180 is discontinued. The direct replacement is the SAI32X180. It is a true ISO 15552 profile cylinder that matches the original 32mm bore, 180mm stroke, 402N force, G1/8 port, and mounting dimensions, dropping directly into existing fixtures.
The 32mm bore features a G1/8 air port and an 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, with a theoretical maximum of 82kgf at 1.0MPa. Operating speed is 30-800mm/s.
