This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X760S, 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 SI63X760S
The AirTAC Airtac SI63 Standard Cylinder SI63X760S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 760mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X760S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X760S
The AirTAC SI63X760S is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 760 mm stroke. It delivers 1559 N push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI63X760S, matching the interface, bore, stroke, force, port and mounting.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The SAI family adds SAIL, SAIF and BSAI lock variants the SI lacked. This -S SKU has a magnet for CS1-B/DS1-B sensors.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAI63X760S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI63 Standard Cylinder SI63X760S Is Used
Long-Stroke Diversion
Pushes heavy pallets laterally across transfer lines using the 760 mm reach and 1559 N thrust at 0.5 MPa.
Automated Press Feed
Advances stock strips into forming machinery where the 30 mm adjustable air cushions absorb end-of-stroke energy.
Replacing the Airtac SI63 Standard Cylinder SI63X760S with the SAI63X760S
To replace the SI63X760S, order the SAI63X760S. Confirm the ISO 15552 mounting interface, 63 mm bore, 760 mm stroke, G3/8 port (PT/G/NPT thread), M16x1.5 rod thread, and the -S magnet for CS1-B/DS1-B switches. Sizing both ways: a 50 mm bore gives 982 N push at 0.5 MPa, while an 80 mm bore gives 2513 N. Note that a 760 mm stroke requires external guides to prevent rod-bending under side loads. A plain cylinder drifts on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X760S
- ✓ 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 SI63X760S FAQ
Yes, the SI63X760S is discontinued. The direct replacement is the SAI63X760S. It is dimensionally interchangeable per ISO 15552, retaining the same 63 mm bore, 760 mm stroke, output force, G3/8 port and mounting fixtures.
The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N push at 0.9 MPa, and a theoretical max of 318 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
