This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X1190, 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 SI63 Standard Cylinder SI63X1190
The AirTAC Airtac SI63 Standard Cylinder SI63X1190 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 1190mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X1190, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X1190
The AirTAC SI63X1190 is a discontinued double-acting ISO 15552 profile cylinder with a 63mm bore and 1190mm stroke, delivering 1559N push force at 0.5MPa through a G3/8 port. AirTAC replaced this legacy unit with the SAI63X1190, a direct upgrade retaining the exact interface, bore, stroke, force, and mounting.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Because this specific SKU lacks a magnet (-S), it cannot accept a CS1-B/DS1-B sensor.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |

Where the Airtac SI63 Standard Cylinder SI63X1190 Is Used
Long-Stroke Transfer
Pushes workpieces between machining stations over a 1190mm travel distance using a robust 1559N push force at 0.5MPa.
Pallet Push-Off
Acts as a diverter arm in packaging lines, utilizing the 63mm bore and G3/8 porting for rapid 30-800mm/s cycling.
Replacing the Airtac SI63 Standard Cylinder SI63X1190 with the SAI63X1190
To replace the SI63X1190, order the SAI63X1190, confirming the ISO 15552 mounting interface, 63mm bore, 1190mm stroke, G3/8 port (PT/G/NPT), and mounting accessory. Neighbouring bores offer alternatives: the 50mm bore yields 982N push at 0.5MPa, while the 80mm bore provides 2513N. Note that this SKU has no magnet, so it cannot support CS1-B/DS1-B switches; order an -S variant if sensing is needed. At 1190mm, this long stroke requires external guides to prevent rod-bending and side-load damage. The air cushion only decelerates the piston; it does not hold load on air loss. For secure holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X1190
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI63 Standard Cylinder SI63X1190 FAQ
Yes, the SI63X1190 is discontinued. The direct replacement is the SAI63X1190. It shares the identical ISO 15552 mounting interface, 63mm bore, 1190mm stroke, output force, G3/8 port, and accessories, fitting directly into existing fixtures.
The 63mm bore uses a G3/8 port. At 0.5MPa it provides 1559N push and 1402N pull force. At 0.7MPa push is 2182N, and at 0.9MPa it is 2805N. The theoretical maximum force is 318kgf at 1.0MPa.
