This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X210, 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 SI80X210
The AirTAC SI80 Standard Air Cylinder SI80X210 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 210mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X210, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X210
The AirTAC SI80X210 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 210 mm stroke. It delivers 2513 N push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80X210, matching the exact interface, bore, stroke, force, port and mounting hardware.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This no-magnet SKU cannot take a sensor, unlike the CS1-B/DS1-B compatible versions.

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 SI80X210 Is Used
Press Fit Assembly
Drives bearings or pins into housings using its 2513 N push force at 0.5 MPa, ensuring consistent seating in automated machining cells.
Pallet Diverter
Actuates routing gates on heavy-duty material handling lines, utilizing the 80 mm bore and 210 mm stroke to shift loaded pallets smoothly.
Carton Flap Folder
Folds large packaging flaps prior to sealing, leveraging the 128 kg vertical lift capacity to handle bulky cardboard cartons reliably.
Replacing the Airtac SI80 Standard Air Cylinder SI80X210 with the SAI80X210
To replace the SI80X210, order the SAI80X210 with the same ISO 15552 mounting interface, 80 mm bore, 210 mm stroke, G3/8 port and M20x1.5 rod thread. Confirm your mounting accessory (LB, FA, TC, etc.) and thread standard (PT, G or NPT). If you need more force, the 100 mm bore yields 3927 N push at 0.5 MPa; if less is required, the 63 mm bore provides 1559 N. Because this SKU lacks the -S magnet, it cannot accept a position sensor. For load holding, note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 210 mm stroke, side-load risks are low, but always guide the load to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X210
- ✓ 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 SI80X210 FAQ
Yes, the AirTAC SI80X210 is discontinued. The direct replacement is the SAI80X210. It is a true ISO 15552 profile cylinder that matches the 80 mm bore, 210 mm stroke, 2513 N force, G3/8 port and mounting interface, fitting directly into existing fixtures.
The bore is 80 mm with a G3/8 air port. At 0.5 MPa it provides 2513 N push and 2268 pull force. At 0.7 MPa push is 3518 N, at 0.9 MPa push is 4523 N, and the theoretical maximum force is 513 kgf at 1.0 MPa.
