This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63AX1300S, 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 SI63AX1300S
The AirTAC SI63 Standard Cylinder SI63AX1300S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 1300mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63AX1300S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63AX1300S
The AirTAC SI63AX1300S is a discontinued double-acting ISO 15552 profile cylinder with a 63mm bore and 1300mm stroke. It delivers 1559N push force at 0.5MPa via a G3/8 port. The direct replacement is the SAI63AX1300S, matching the bore, stroke, force, port, and ISO 15552 mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This -A variant uses a SUS420J2 stainless rod, and the -S magnet works with legacy CS1-B/DS1-B sensors. For load holding, note the air cushion only decelerates; use SAIL or BSAI lock variants.

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 SAI63AX1300S 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 SI63AX1300S Is Used
Long-Stroke Diversion
Pushes heavy pallets across 1.3m transfer lines where the 1559N force handles lateral shifting reliably.
High-Bay Extraction
Extracts totes from deep racking; the SUS420J2 stainless rod resists moisture in humid warehouse environments.
Replacing the Airtac SI63 Standard Cylinder SI63AX1300S with the SAI63AX1300S
To replace the SI63AX1300S, order the SAI63AX1300S. Confirm the ISO 15552 mounting interface, G3/8 port, M16x1.5 rod thread, SUS420J2 stainless rod (-A), and the -S magnet for current AirTAC switches. For sizing, the 63mm bore yields 1559N push at 0.5MPa; dropping to 50mm gives 982N, while 80mm provides 2513N. At 1300mm stroke, use external guides to prevent rod bending and side-load wear. A plain cylinder drifts without air; for load holding, select the SAIL lock or BSAI clamp-lock variant, or add a pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63AX1300S
- ✓ 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 SI63AX1300S FAQ
Yes, the SI63AX1300S is discontinued. The direct replacement is the SAI63AX1300S. It features the same ISO 15552 mounting interface, 63mm bore, 1300mm stroke, G3/8 port, and output force, fitting existing fixtures perfectly.
This 63mm bore cylinder uses a G3/8 air port. It generates 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and 2805N push at 0.9MPa. The theoretical maximum force is 318kgf at 1.0MPa.
