This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X450TC, 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 SI32X450TC
The AirTAC SI32 Standard Air Cylinder SI32X450TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 450mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X450TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X450TC
The AirTAC SI32X450TC is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 450mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X450TC. This direct upgrade shares the exact TC trunnion mounting, stroke, and output force.
The SAI features an upgraded piston seal with two Y-shaped elements for low start-up pressure. Note this non-magnet SKU cannot hold a load without air; consider SAIL lock variants. The 450mm stroke requires external guides to prevent rod bending.

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 SI32X450TC Is Used
Light-Duty Ejection
Ideal for pushing small parts from a machining fixture using 402N of push force at 0.5 MPa.
Material Transfer
Moves lightweight bins between zones where a 20kg vertical lift capacity is sufficient.
Replacing the Airtac SI32 Standard Air Cylinder SI32X450TC with the SAI32X450TC
To replace the SI32X450TC, order the SAI32X450TC. Verify the ISO 15552 TC trunnion interface, 32mm bore, 450mm stroke, and G1/8 port. This non-magnet SKU cannot accept a sensor. If sizing up, a 40mm bore yields 628N push at 0.5MPa. For load holding on air loss, use an external pilot check valve or the SAIL lock variant, as cushions only decelerate. At 450mm stroke, use external guides to manage side loads and prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X450TC
- ✓ 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 SI32X450TC FAQ
Yes, the SI32X450TC is discontinued. The direct replacement is the SAI32X450TC. It shares the same ISO 15552 mounting interface, 32mm bore, 450mm stroke, force, and G1/8 port, fitting existing fixtures perfectly.
The 32mm bore uses a G1/8 port. It generates 402N push and 345N pull at 0.5 MPa, 563N push at 0.7 MPa, 724N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. The rod is 12mm with an M10x1.25 thread.
