This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X380CA, 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 SI80X380CA
The AirTAC SI80 Standard Air Cylinder SI80X380CA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 380mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X380CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X380CA
The AirTAC SI80X380CA is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 380mm stroke. Generating 2513 N push and 2268 N pull at 0.5 MPa, it uses a G3/8 port and M20x1.5 rod thread. AirTAC replaced this legacy unit with the SAI80X380CA, a direct sharing the exact ISO 15552 mounting interface, CA clevis, force, and stroke.
The SAI upgrade features a revised piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Because this specific SKU lacks the -S magnet, it cannot accept a CS1-B or DS1-B sensor.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SI80 Standard Air Cylinder SI80X380CA Is Used
Pallet Diversion
Routes heavy pallets on packaging lines using the 2513 N push force at 0.5 MPa, with the CA clevis accommodating articulation.
Press Ejection
Ejects formed metal components from a press, relying on the 36mm adjustable air cushions to decelerate the 25mm rod smoothly.
Replacing the Airtac SI80 Standard Air Cylinder SI80X380CA with the SAI80X380CA
To replace the SI80X380CA, order the SAI80X380CA. Confirm the ISO 15552 interface, 80mm bore, 380mm stroke, G3/8 port (PT/G/NPT thread options), and CA clevis mounting. Since this SKU has no -S suffix, it cannot support magnetic sensing. If sizing up or down, neighbouring bores (63mm or 100mm) offer 1559 N or 3927 N push at 0.5 MPa respectively. Note that a plain cylinder drifts on air loss; the air cushion only decelerates near stroke end. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. At 380mm, prevent rod bending by using an external guide to manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X380CA
- ✓ 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 SI80X380CA FAQ
Yes, the SI80X380CA is discontinued. The direct replacement is the SAI80X380CA. It shares the identical ISO 15552 mounting interface, 80mm bore, 380mm stroke, G3/8 port, and CA clevis, fitting directly into existing fixtures.
It features a G3/8 air 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, with a theoretical max of 513 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
