This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X332S, 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 SI63X332S
The AirTAC Airtac SI63 Standard Cylinder SI63X332S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 332mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X332S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X332S
The AirTAC SI63X332S is a discontinued double-acting ISO 15552 profile cylinder with a 63mm bore and 332mm stroke, delivering 1559N push at 0.5MPa through a G3/8 port. The direct replacement is the SAI63X332S, matching the interface, force, and mounting exactly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The -S suffix means a piston magnet for legacy CS1-B/DS1-B sensors; the SAI uses current AirTAC switches. The SAI family also adds SAIL, SAIF, and BSAI lock variants absent in the SI line.

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 SAI63X332S 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 SI63X332S Is Used
Pallet Diversion
Actuates routing gates on packaging lines using the 1559N push force, with the 332mm stroke clearing pallet profiles.
Material Press
Provides consistent downward clamping pressure for component seating, safely operating within the 935N working load.
Vertical Lift Gate
Raises and lowers access barriers; the 79kg vertical lift capacity handles standard aluminum gate panels.
Replacing the Airtac SI63 Standard Cylinder SI63X332S with the SAI63X332S
To replace the SI63X332S, order the SAI63X332S. Confirm the ISO 15552 mounting accessory (LB, FA, CA, TC), the G3/8 port thread (PT/G/NPT), and the -S magnet requirement. Sizing both ways: a 50mm bore yields 982N [email protected], while an 80mm bore yields 2513N. The 332mm stroke requires external guides to prevent rod bending and side-load wear. A plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X332S
- ✓ 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 SI63X332S FAQ
Yes, the SI63X332S is discontinued. The direct replacement is the SAI63X332S. It is dimensionally interchangeable per ISO 15552, matching the 63mm bore, 332mm stroke, G3/8 port, and mounting fixtures.
The 63mm bore uses a G3/8 port. At 0.5MPa it pushes 1559N and pulls 1402N. At 0.7MPa push is 2182N, and at 0.9MPa it is 2805N. The theoretical maximum force is 318kgf at 1.0MPa.
