Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800S-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800S-10A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 800mm stroke and a built-in 4M310-10 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 SAUF80X800S-10A
The SAUF80X800S-10A 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 makes it shorter than an ISO 15552 unit of the same bore. It features a 3/8" valve port, 3/8" cylinder port, and an M20x1.5 rod thread.
Operating strictly within the 0.15-0.8 MPa valve window, it delivers a push force of 2513 N at 0.5 MPa and 4021 N at 0.8 MPa. The valve flows 30 mm2 (Cv 1.68) at up to 4 cycles per second. The AC220V terminal entry coil is IP65 rated. Based on the 0.5 MPa push figure, the safe working load is roughly 1508 N, allowing a vertical lift of about 128 kg with a 2:1 margin. This 800 mm stroke unit includes a piston magnet for CMSG/DMSG/EMSG switches.

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 SAUF80X800S-10A Is Used
Pallet Divertor
Uses the self-contained 4M310 valve to push heavy pallets off a high-speed line without running long tubing back to a central manifold.
Vertical Lift Gate
Lifts gates up to 128 kg using a single AC220V signal, relying on the 800 mm stroke and built-in magnet for position feedback.
Press Ejection
Ejects formed parts at up to 4 cycles per second, benefiting from the 3/8" valve port and 30 mm2 flow to cycle quickly.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800S-10A the Right Choice?
Size by checking both neighboring bores: the 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. This 80 mm bore gives 2513 N at 0.5 MPa and 4021 N at 0.8 MPa. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry coil meets your supply. The rod retracts when energized by default, but you can reposition the valve to extend on signal. Because the 800 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side-load wear. The valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve.
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 SAUF80X800S-10A FAQ
It pushes 2513 N at 0.5 MPa and 4021 N at 0.8 MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, 4 cycles/s max). The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window. The coil is AC220V with terminal entry.
No, the built-in valve only routes air and is not a load lock; the piston will drift on air loss. Add an external rod lock or pilot-operated check valve for holding. By default the rod retracts when the coil is energized, but you can reposition the valve to extend on signal.
