This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X1100, 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 SI32X1100
The AirTAC SI32 Standard Air Cylinder SI32X1100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 1100mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X1100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X1100
The AirTAC SI32X1100 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 1100mm stroke. Generating 402N push force at 0.5MPa, it is replaced by the SAI32X1100. This direct upgrade keeps the G1/8 port, M10x1.25 thread, and mounting dimensions. Note that 1100mm exceeds the 1000mm standard stroke limit, making it a non-standard made-to-order item.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. For applications needing load holding, the SI lacks locking; consider the SAIL or BSAI variants. This SKU lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors.

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 SI32X1100 Is Used
Long-Stroke Diversion
Handles 1100mm routing of light packages on conveyor lines, utilizing the 402N push force to push items cleanly without overloading the 32mm bore.
Vertical Material Lift
Raises lightweight totes up to 20kg in automated storage systems, requiring external guides to manage the 1100mm extended rod length safely.
Remote Actuation
Deploys tooling or doors across a 1.1m gap in assembly machinery where the compact 32mm bore and G1/8 port minimize space and air consumption.
Replacing the Airtac SI32 Standard Air Cylinder SI32X1100 with the SAI32X1100
To replace the discontinued SI32X1100, order the SAI32X1100. Verify the ISO 15552 interface, G1/8 port, and mounting accessories. Because this is a non-standard 1100mm stroke exceeding the 1000mm bore limit, expect made-to-order lead times. At 1100mm, add external guides to prevent rod bending and side-load damage. This plain cylinder drifts without live air; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. If sizing down, a 32mm bore yields 402N push at 0.5MPa; sizing up to 40mm provides 628N. Without the -S magnet, switch sensing is impossible.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X1100
- ✓ 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 SI32X1100 FAQ
Yes, the SI32X1100 is discontinued. The direct replacement is the SAI32X1100. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 1100mm stroke, 402N force, G1/8 port, and mounting interface. You can order the SAI32X1100 directly.
This double-acting cylinder operates at 30-800 mm/s with a G1/8 port and M10x1.25 rod thread. Force ratings are: 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 1100mm stroke is non-standard.
