Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400S-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 400mm 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 SAUF80X400S-08A
The SAUF80X400S-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. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
Operating in the 0.15-0.8 MPa valve window, this 80mm bore delivers 2513N push at 0.5 MPa. The computed safe working load is roughly 1508N, allowing a 2:1 margin vertical lift of about 128kg. The 4M310-08 valve has a 1/4" port, Cv 1.4, and cycles up to 4 times per second. The cylinder port is 3/8". Note the 1.0 MPa cylinder body rating is capped by the 0.8 MPa valve limit.

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 SAUF80X400S-08A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert station. The integrated 4M310 valve fires the 400mm stroke to push parcels without tubing runs back to a central manifold.
Vertical Lift Gate
Lifts materials using the 2513N push force at 0.5 MPa. The built-in piston magnet works with DMSG sensors to confirm gate position.
Machine Guard Door
Cycles the guard door at up to 4 cycles per second. The AC220V coil switches locally, ensuring fast response without manifold delays.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400S-08A the Right Choice?
Size by checking both neighboring bores: the 63mm bore offers 1559N push at 0.5 MPa, while the 100mm bore provides 3927N. This 80mm bore gives 2513N push and 2268N pull at 0.5 MPa. Confirm the AC220V terminal entry and PT thread suit your control panel. Default action retracts the rod when energized, but you can reposition the valve to extend on signal. Because the 400mm stroke exceeds 300mm, add external guides to prevent rod bending and side-load wear. The valve routes air but does not lock the load; for drop prevention install 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 SAUF80X400S-08A FAQ
It pushes 2513N and pulls 2268N at 0.5 MPa, reaching 4021N at 0.8 MPa. The built-in valve is a 4M310-08 with a 1/4" port and Cv 1.4. The AC220V coil runs at 3.5 VA with IP65 protection. Size the force within the 0.15-0.8 MPa valve window, as the assembled unit cannot use the 1.0 MPa cylinder body rating.
Yes. The default configuration retracts the rod when the coil receives power. You can reconfigure it to extend on energization by physically repositioning the built-in valve. This local switching means you need only one coil signal and no remote valve manifold to drive the actuator.
