This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1230S, 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 SI80X1230S
The AirTAC SI80 Standard Air Cylinder SI80X1230S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1230mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1230S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1230S
The AirTAC SI80X1230S is a discontinued double-acting ISO 15552 profile cylinder with a 1230 mm stroke. It delivers 2513 N push force at 0.5 MPa through a G3/8 port. AirTAC replaced this legacy unit with the SAI80X1230S, a direct upgrade sharing the exact same ISO 15552 mounting interface, bore, and output force.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B sensors, while the SAI family also introduces SAIL, SAIF, and BSAI lock variants absent in the SI line.

Where the Airtac SI80 Standard Air Cylinder SI80X1230S Is Used
Long-Stroke Diversion
Actuates large diverter arms on material handling lines, utilizing the full 1230 mm travel to route heavy pallets.
High-Reach Elevation
Lifts vertical loads up to 128 kg in automated storage systems, relying on the 2513 N thrust at 0.5 MPa.
Industrial Pressing
Provides steady 80 mm bore clamping force for assembly fixtures, ensuring components are seated securely.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1230S with the SAI80X1230S
To replace the SI80X1230S, order the SAI80X1230S. Confirm the ISO 15552 mounting interface, the G3/8 port, the M20x1.5 rod thread, and your mounting accessory (LB, FA, TC, etc.). The -S magnet is present, so specify current AirTAC switches to replace the legacy CS1-B/DS1-B units. When sizing, a 63 mm bore yields 1559 N push at 0.5 MPa, whereas an 100 mm bore yields 3927 N. Because this is a 1230 mm long stroke, external guides are strongly recommended to prevent rod bending and excessive side loads. A plain cylinder drifts without air; for load holding on pressure loss, use an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1230S
- ✓ 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 SI80X1230S FAQ
Yes, the SI80X1230S is discontinued. The direct replacement is the SAI80X1230S, which shares the identical ISO 15552 mounting interface, 80 mm bore, 1230 mm stroke, G3/8 port, and output force.
It features a G3/8 air port and provides 2513 N push / 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
