Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225S-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 225mm stroke and a built-in 4M310-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225S-08A
The SAUF80X225S-08A is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve mounted directly on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than a standard ISO 15552 unit of the same bore. It features a 225 mm stroke, a Ø25 mm rod, M20x1.5 rod thread, and a 3/8" cylinder port.
Operating within the valve's 0.15-0.8 MPa window, it delivers a push force of 2513 N at 0.5 MPa. The integrated valve provides a 1/4" port, 25 mm2 flow (Cv 1.4), and switches up to 4 cycles per second. The AC220V terminal entry coil is IP65 rated with a 0.05 s response. For sizing, the safe working load is roughly 1508 N, and it can vertically lift about 128 kg with a 2:1 margin. The S suffix denotes a piston magnet for position sensing.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAUF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAUF datasheet. Port options: PT / G.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAUF does not hold its load without air — the valve routes air, it is not a lock. For a held load, add an external rod lock or a pilot-operated check valve.
Where the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225S-08A Is Used
Decentralized Clamping
Ideal for large machining cells where running a dedicated manifold line is costly; the integrated valve clamps parts directly at the fixture using one AC220V signal.
Inline Divert Gate
Actuates a diverting gate on a packaging line. The built-in 4M310 valve handles the 4 cycle/sec demand perfectly without consuming manifold space.
Independent Lift Station
Powers a localized vertical lift in a high-bay warehouse. The compact profile and self-contained switching simplify installation on independent sub-assemblies.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225S-08A the Right Choice?
Size this 80 mm bore against the neighbouring 63 mm and 100 mm options. At 0.5 MPa it pushes 2513 N and pulls 2268 N; stepping up to the 100 mm bore yields 3927 N push, while dropping to 63 mm provides 1559 N. Confirm the AC220V terminal entry and PT threads match your supply. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 225 mm stroke, ensure adequate side-load guidance.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → external rod lock
Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225S-08A FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25 mm2 flow) with an AC220V terminal coil. Although the cylinder body rates to 1.0 MPa, you must size force within the valve's 0.15-0.8 MPa operating window.
Yes. The default factory setting retracts the rod when energised. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This self-switching design removes the need for any remote valve or extra tubing.
