This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X1430S, 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 SI63X1430S
The AirTAC Airtac SI63 Standard Cylinder SI63X1430S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 1430mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X1430S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X1430S
The AirTAC SI63X1430S is a discontinued double-acting ISO 15552 profile cylinder with a 63mm bore and 1430mm stroke. Delivering 1559N push force at 0.5MPa via a G3/8 port, it is replaced by the SAI63X1430S direct. The SAI retains identical ISO 15552 mounting, force, and stroke, fitting existing fixtures perfectly.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This -S model has a magnet for legacy CS1-B/DS1-B sensors. For load holding, the SAIL or BSAI lock variants are needed, as plain cylinders drift without air.

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 SI63X1430S Is Used
Long-Stroke Diversion
Pushes heavy pallets across wide conveyor lanes using the 1430mm stroke and 1559N force, requiring external guides to prevent rod bending.
Assembly Press
Applies up to 318kgf clamping force at 1.0MPa for component seating, using the G3/8 port and adjustable 30mm cushions for smooth stops.
Replacing the Airtac SI63 Standard Cylinder SI63X1430S with the SAI63X1430S
To replace the SI63X1430S, order the SAI63X1430S keeping the identical ISO 15552 interface, 63mm bore, 1430mm stroke, G3/8 port, and magnet. This is a nonstandard stroke (exceeding the 1500mm max standard is false, 1430 is within max but long), so at 1430mm you must use external guides to prevent rod bending and side-load damage. Size both ways: a 50mm bore yields 982N push @0.5MPa, while an 80mm bore yields 2513N. A plain cylinder does not hold load without air; use an external rod lock or pilot check valve, or choose the SAIL lock variant. The SAI family also adds the SAIF valve variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X1430S
- ✓ 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 SI63X1430S FAQ
Yes, the AirTAC SI63X1430S is discontinued. The direct replacement is the SAI63X1430S. It is a true ISO 15552 profile cylinder with the same 63mm bore, 1430mm stroke, G3/8 port, and mounting interface, dropping directly into existing fixtures.
The 63mm bore uses a G3/8 port with a 20mm rod. Force output is 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, 2805N push at 0.9MPa, and a theoretical max of 318kgf at 1.0MPa. Speed is 30-800mm/s.
