Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350S-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 350mm 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 SAUF80X350S-08A
The SAUF80X350S-08A is a double-acting profile cylinder with a built-in AirTAC 4M310 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. This 80mm bore version pushes 2513N at 0.5MPa and includes a piston magnet for switches.
The integrated valve has a 1/4-inch port, 25mm2 flow (Cv 1.4), and cycles up to 4 times per second. The cylinder body rates to 1.0MPa, but you must size force within the valve's 0.15-0.8MPa operating window. Based on the 0.5MPa push force, the safe working load is about 1508N, yielding a vertical lift capacity of roughly 128kg with a 2:1 margin. The AC220V terminal entry coil is IP65 rated.

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 SAUF80X350S-08A Is Used
Decentralized Conveyor Diverter
Mounts directly at the divert station. One AC220V signal actuates the 4M310 valve to push packages, removing the need to trace tubing back to a central manifold.
Independent Stacking Gate
Ideal for standalone palletising gates. The built-in valve handles the 350mm stroke with 2513N push force at 0.5MPa, simplifying machine expansion.
Remote Forming Press Ejector
Ejects parts on the periphery of a large press. The IP65 coil and integrated switching valve survive harsh shop floors while saving manifold space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350S-08A the Right Choice?
Size this 80mm bore against the neighbouring 63mm and 100mm options. At 0.5MPa it pushes 2513N and pulls 2268N. Confirm the AC220V terminal coil voltage matches your supply. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Always operate within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder body rating. The built-in valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. For the 350mm stroke, use external guides to prevent rod bending and side-load wear. The cylinder air port is 3/8-inch and the rod thread is M20x1.5.
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 SAUF80X350S-08A FAQ
It pushes 2513N and pulls 2268N at 0.5MPa, reaching 4021N at 0.8MPa. The built-in valve is a 4M310-08 (1/4-inch port, Cv 1.4, 4 cycles/s max). The cylinder body rates to 1.0MPa, but the assembled unit must operate within the 0.15-0.8MPa valve window. The coil is AC220V with terminal entry.
No. The built-in 5/2 valve routes air but does not lock the piston. If air is lost, the load drifts. For vertical load holding, install an external rod lock or pilot-operated check valve. The default action retracts when energised, but you can reposition the valve to extend on signal.
