This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X1480S, 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 SI63X1480S
The AirTAC Airtac SI63 Standard Cylinder SI63X1480S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 1480mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X1480S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X1480S
The AirTAC SI63X1480S is a discontinued double-acting ISO 15552 profile cylinder with a 63mm bore and 1480mm stroke. It delivers 1559N push force at 0.5MPa through a G3/8 port. AirTAC replaced this legacy unit with the SAI63X1480S, a direct alternative retaining the exact interface, bore, stroke, force, and mounting.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also introduces SAIL, SAIF, and BSAI lock variants the SI lacked. This -S model has a piston magnet for CS1-B/DS1-B switches.

Where the Airtac SI63 Standard Cylinder SI63X1480S Is Used
Long-Stroke Transfer
Pushes workpieces between machining stations over a 1480mm span, relying on the 1559N thrust at 0.5MPa to move heavy jigs smoothly.
High-Bay Extraction
Extracts totes from deep racking where the 63mm bore provides enough force to overcome guide friction on long horizontal travels.
Large Press Feed
Feeds heavy sheet stock into a press, using the adjustable 30mm cushions to decelerate the payload at the end of the 1480mm stroke.
Replacing the Airtac SI63 Standard Cylinder SI63X1480S with the SAI63X1480S
To replace the SI63X1480S, order the SAI63X1480S. Confirm the ISO 15552 mounting interface, 63mm bore, 1480mm stroke, G3/8 port (PT/G/NPT), and mounting accessory. The -S suffix means a magnet is present for CS1-B/DS1-B sensors. Sizing both ways: a 50mm bore gives 982N push at 0.5MPa, while an 80mm bore yields 2513N. At 1480mm, prevent rod bending by using an external guide to absorb side loads. 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.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X1480S
- ✓ 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 SI63X1480S FAQ
Yes, the SI63X1480S is discontinued. The direct replacement is the SAI63X1480S. It is dimensionally interchangeable per ISO 15552, keeping the same 63mm bore, 1480mm stroke, G3/8 port, and mounting interface, so it fits existing fixtures perfectly.
The G3/8 port feeds a 20mm rod. Forces are: 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, 2805N push at 0.9MPa, and a 318kgf theoretical max at 1.0MPa. Speed is 30-800mm/s.
