This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X1300S, 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 SI63X1300S
The AirTAC Airtac SI63 Standard Cylinder SI63X1300S 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 SAI63X1300S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X1300S
The AirTAC SI63X1300S is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 1300 mm stroke. It delivers 1559 N push at 0.5 MPa through a G3/8 port. AirTAC replaced this legacy unit with the SAI63X1300S, a direct sharing the same ISO 15552 mounting interface, bore, stroke, force and accessories.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. The SAI family adds SAIL lock, SAIF valve and BSAI clamp variants the SI lacked. This -S SKU uses 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 SAI63X1300S 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 SI63X1300S Is Used
Long-Stroke Diversion
Pushes heavy pallets across wide transfer lines using the 1300 mm stroke and 1559 N force at 0.5 MPa.
High-Bay Extraction
Extracts totes from deep shelving racks where the 63 mm bore provides the reach and thrust needed for loaded containers.
Large Press Feed
Feeds heavy sheet metal stock into presses, relying on the G3/8 port and adjustable cushions to handle rapid cycles.
Replacing the Airtac SI63 Standard Cylinder SI63X1300S with the SAI63X1300S
To replace the SI63X1300S, order the SAI63X1300S. Verify the ISO 15552 mounting interface, 1300 mm stroke, G3/8 port (PT/G/NPT thread options) and mounting accessory. The -S suffix means a piston magnet for CS1-B/DS1-B switches; the SAI uses current AirTAC switches. Neighbouring bores are 50 mm (982 N push @0.5) and 80 mm (2513 N push @0.5). 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. At 1300 mm, prevent rod bending by using an external guide to absorb side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X1300S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
