This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X226, 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 SI80X226
The AirTAC SI80 Standard Air Cylinder SI80X226 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 226mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X226, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X226
The AirTAC SI80X226 is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 226mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa via a G3/8 port. The direct replacement is the SAI80X226, which shares the same interface, force, and mounting.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. Note this nonstandard 226mm stroke exceeds standard increments. This SKU lacks a magnet, so it cannot take a CS1-B/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 SI80X226 Is Used
Clamp Actuation
Provides 2513N of clamping force at 0.5MPa for securing heavy weldments during machining operations.
Package Diversion
Drives a 226mm stroke diverter arm to route mid-weight pallets on a high-speed packaging line.
Replacing the Airtac SI80 Standard Air Cylinder SI80X226 with the SAI80X226
To replace the SI80X226, order the SAI80X226 and confirm the ISO 15552 mounting interface, G3/8 port, and M20x1.5 rod thread. Because this 226mm stroke is nonstandard, verify exact delivery. Sizing both ways: a 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore yields 3927N. For side-load resistance over this 226mm stroke, use guide rails. This plain cylinder cannot hold load without air; use an external pilot check valve or the SAIL/BSAI lock variant. The SAI family also offers the SAIF self-valve option.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X226
- ✓ 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 SI80X226 FAQ
Yes, the SI80X226 is discontinued. The direct replacement is the SAI80X226. It is dimensionally interchangeable per ISO 15552, retaining the same 80mm bore, 226mm stroke, G3/8 port, and mounting accessories.
It uses a G3/8 port. Force output is 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a theoretical max of 513kgf at 1.0MPa. Speed is 30-800mm/s.
