This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1450, 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 SI100 Standard Cylinder SI100X1450
The AirTAC Airtac SI100 Standard Cylinder SI100X1450 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1450mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1450, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1450
The AirTAC SI100X1450 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 1450mm stroke. It delivers a push force of 3927 N at 0.5 MPa (5497 N at 0.7 MPa) via a G1/2 port. AirTAC replaced this legacy unit with the SAI100X1450, a direct upgrade retaining the exact interface, bore, stroke, output force, and mounting dimensions.
The SAI successor features an upgraded piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. Note this specific SKU lacks a magnet (-S) and cannot accept position sensors; the legacy SI family used CS1-B/DS1-B switches. Furthermore, the SAI line introduces SAIL, SAIF, and BSAI lock and valve variants absent in the original SI range.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100X1450 Is Used
Long-Stroke Material Transfer
Pushes heavy pallets or workpieces across extended conveyor gaps using its 1450mm reach and 5497 N output at 0.7 MPa.
High-Reach Vertical Lifting
Elevates loads up to 200 kg in storage retrieval systems, requiring external guides to manage the 1.45-meter rod extension safely.
Large Press Ejection
Kicks out finished parts from heavy stamping presses, relying on the adjustable 36mm air cushions to decelerate the 25mm rod at high speeds.
Replacing the Airtac SI100 Standard Cylinder SI100X1450 with the SAI100X1450
To replace the SI100X1450, order the SAI100X1450. Verify your ISO 15552 mounting hardware (LB, FA, TC, etc.), the G1/2 port, and the M20x1.5 rod thread. Because this 1450mm stroke is very long, prevent rod bending and premature seal wear by guiding the load externally to avoid side-load forces. Sizing both ways: if you need less force, a bore 80 cylinder offers 2513 N push at 0.5 MPa; if you need more, a bore 125 provides 6136 N. Remember that a standard cylinder does not hold load on air loss—the cushions only decelerate. For load holding, use an external pilot check valve, a rod lock, or specify the SAIL/BSAI locking variants. Finally, since this SKU has no magnet, you cannot mount reed sensors; if sensing is required, select an SAI model with the -S magnet option.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1450
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100X1450 FAQ
Yes, the SI100X1450 is discontinued. The direct replacement is the SAI100X1450. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 1450mm stroke, G1/2 port, and mounting interface, but adds an upgraded Y-shaped piston seal for longer life.
This double-acting cylinder uses a G1/2 air port. The thrust ratings are: 3927 N push and 3681 N pull at 0.5 MPa; 5497 N push at 0.7 MPa; 7068 N push at 0.9 MPa; and a theoretical maximum force of 801 kgf at 1.0 MPa.
