This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X600, 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 SI32X600
The AirTAC SI32 Standard Air Cylinder SI32X600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 600mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X600
The AirTAC SI32X600 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 600mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X600. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, force and accessories.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also adds SAIL, SAIF and BSAI variants the SI lacked. This non-magnet SKU cannot take a 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 SI32X600 Is Used
Long-Stroke Diversion
Pushes light packages across a conveyor belt at 600mm stroke, operating safely within the 241N working load limit for routing gates.
Linear Part Ejection
Ejects small machined components from a fixture, utilizing the 32mm bore's 402N thrust and adjustable 27mm air cushions.
Replacing the Airtac SI32 Standard Air Cylinder SI32X600 with the SAI32X600
To replace the SI32X600, order the SAI32X600. Confirm the ISO 15552 mounting interface (LB, FA, CA, TC), G1/8 port, and M10x1.25 rod thread. As this SKU lacks the -S magnet, it cannot accept CS1-B/DS1-B sensors. Neighbouring bore 40 offers 628N. Note: a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. With a 600mm stroke, use external guides to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X600
- ✓ 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 SI32X600 FAQ
Yes, the SI32X600 is discontinued. The direct replacement is the SAI32X600. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 600mm stroke, 402N force, G1/8 port and mounting interface.
This double-acting cylinder uses a G1/8 port. It delivers 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.
