Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400-10A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 400mm 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 SAUF80X400-10A
The SAUF80X400-10A is a double-acting profile-type cylinder with a built-in AirTAC 4M310-10 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. This 80mm bore delivers 2513N push and 2268N pull at 0.5MPa, operating within the valve's 0.15-0.8MPa range. The cylinder port is 3/8" and the rod end thread is M20x1.5.
The integrated valve provides a 30mm2 flow (Cv 1.68) and switches up to 4 cycles per second. It uses terminal entry with PT threads and connects via PU tube Ø10xØ6.5. For sizing, the safe working load is roughly 1508N (60% of the 0.5MPa push force), and the vertical lift capacity is about 128kg with a 2:1 margin. This SKU lacks the S magnet suffix, so it cannot accept a magnetic switch.

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 SAUF80X400-10A Is Used
Decentralized Press Clamping
Ideal for large press lines where running a single AC220V signal to each clamp saves manifold space and complex tubing.
Inline Divert Gate
Handles heavy package diverting using the 4M310-10 valve's Cv 1.68 flow for rapid 400mm gate actuation at 4 cycles per second.
Independent Machine Lifts
Perfect for standalone lift stations requiring 128kg vertical lift capacity, operating directly from local air without a central valve island.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400-10A the Right Choice?
When sizing, compare neighboring bores: the 63mm bore offers 1559N push at 0.5MPa, while the 100mm bore provides 3927N. This 80mm actuator delivers 2513N push at 0.5MPa. Always confirm the AC220V terminal entry and PT thread match your control scheme. The cylinder body rates to 1.0MPa, but you must size force within the built-in valve's 0.15-0.8MPa working window. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. The 5/2 valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For this 400mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF80X400-10A FAQ
It generates 2513N push and 2268N pull at 0.5MPa, reaching 4021N push at 0.8MPa. The built-in valve is a 4M310-10 5/2 solenoid with 3/8" ports, Cv 1.68, and runs on AC220V. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within the valve's 0.15-0.8MPa window.
The 5/2 valve only routes air and does not lock the load; the piston drifts on air loss, so add an external rod lock or pilot-operated check valve for holding. By default the rod retracts when the coil energizes, but you can reposition the valve to make it extend upon energization.
