About the Airtac SAI80 Standard Air Cylinder SAI80X225S
The AirTAC SAI80X225-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering 2513 N of push force at 0.5 MPa, this 80mm bore unit paired with a 225mm stroke excels in mid-cycle positioning tasks. The extruded aluminum barrel design omits tie-rods, providing a clean profile while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
Configured with a standard carbon steel piston rod and a built-in magnet (-S), this model is fully compatible with CMSE and DMSE reed switches mounted into the dual-side sensor grooves. For environments pushing toward the 70 C limit, specifying the Viton (H) seal option extends thermal reliability beyond the standard TPU pack.

Where the Airtac SAI80 Standard Air Cylinder SAI80X225S Is Used
Automated Pressing
Provides 2513 N of thrust at 0.5 MPa for assembling bearings and seating components in automated press lines.
Material Diverting
Drives heavy-duty divert arms and pallet stops on packaging conveyors where robust 80mm bore force is required.
Plastic Molding Eject
Handles the positive ejection of molded parts from fixtures, utilizing the 225mm stroke to clear the mold area completely.
Is the Airtac SAI80 Standard Air Cylinder SAI80X225S the Right Cylinder?
Stepping up from a 63mm bore yields a significant force jump from 1559 N to 2513 N at 0.5 MPa, making this 80mm unit ideal when the smaller class lacks thrust. If you need less force, dropping to the 63mm bore saves space and air consumption. At 225mm stroke, side load is minimal, but always ensure rigid mounting using the FA flange or LB foot brackets to prevent rod-bearing wear.
Because it is a double-acting cylinder, the SAI80X225-S relies on continuous air pressure to hold position. If your application must resist drift or hold a load during an air loss event, integrate the SAIL variant with an air-released lock or use an external pilot-operated check valve. For exact drop-in replacement matching, verify the 80mm bore, 225mm stroke, G3/8 port, and PT thread type.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI80 Standard Air Cylinder SAI80X225S FAQ
At 0.5 MPa operating pressure, the 80mm bore generates 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, the theoretical push force reaches 513 kgf.
Yes. The SAI80X225-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions and G3/8 port locations are directly interchangeable with other ISO 15552 cylinders, provided you match the 225mm stroke and PT thread.
