This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1560S, 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 SI80 Standard Air Cylinder SI80X1560S
The AirTAC SI80 Standard Air Cylinder SI80X1560S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1560mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1560S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1560S
The AirTAC SI80X1560S is a discontinued double-acting ISO 15552 profile cylinder with a 1560 mm stroke. Because 1560 mm exceeds the 1500 mm standard maximum for this 80 mm bore, this is a non-standard, made-to-order unit. It delivers 2513 N push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80X1560S, matching the ISO 15552 mounting interface, bore, stroke, force, and port size.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family adds SAIL, SAIF, and BSAI lock variants the SI lacked. Your -S magnet works with legacy CS1-B/DS1-B sensors, though SAI uses current AirTAC switches.

Where the Airtac SI80 Standard Air Cylinder SI80X1560S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets across wide conveyor gaps using the 2513 N thrust at 0.5 MPa, requiring external guide rails to support the extended 1560 mm rod.
High-Bay Storage Extraction
Extracts deep-loaded totes from automated racking, relying on the 80 mm bore and G3/8 air supply for consistent actuation over the long travel distance.
Large Press Ejection
Ejects formed parts from heavy industrial presses, utilizing the 4523 N push force at 0.9 MPa to clear the mold area completely.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1560S with the SAI80X1560S
To replace this SI80X1560S, order the SAI80X1560S. Confirm the ISO 15552 mounting interface, the 80 mm bore, the 1560 mm non-standard stroke, the G3/8 port (PT/G/NPT), and the -S magnet. Because this 1560 mm stroke exceeds the 1500 mm standard, expect a made-to-order lead time and ensure external guides are used to prevent rod bending under side loads. If sizing alternatives, neighboring bores (63 mm or 100 mm) offer 1559 N or 3927 N push at 0.5 MPa. A plain cylinder drifts on air loss since 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 → SAI80X1560S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI80 Standard Air Cylinder SI80X1560S FAQ
Yes, the SI80X1560S is discontinued. The direct replacement is the SAI80X1560S. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 80 mm bore, 1560 mm stroke, output force, G3/8 port, and mounting accessories.
This double-acting cylinder operates at 0.15-1.0 MPa (proof 1.5 MPa) with a speed of 30-800 mm/s. It has a G3/8 port and M20x1.5 rod thread. Force output is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical max of 513 kgf at 1.0 MPa.
