Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400S-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400S-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 SAUF80X400S-10A
The SAUF80X400S-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 in decentralized installations. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. This 80mm bore model includes a piston magnet for position sensing and delivers 2513N push at 0.5MPa.
The integrated 4M310-10 valve has a 3/8" port, Cv 1.68 flow, and cycles up to 4 times per second. It runs on AC220V terminal entry with IP65 protection. Size forces within the valve's 0.15-0.8MPa window, not the 1.0MPa cylinder body rating. Based on the 0.5MPa push force, the safe working load is about 1508N, and the vertical lift capacity is roughly 128kg with a 2:1 margin. The cylinder port is 3/8" and uses PU tube Ø10xØ6.5.

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)

| 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-10A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate to push packages, needing only one electrical signal instead of long air lines back to a central manifold.
Machine Tool Clamp
Provides standalone clamping action on a large machining center, saving manifold space while offering position feedback via the magnetic piston.
Vertical Lift Gate
Raises a loading dock gate using the 128kg vertical lift capacity, operating independently within the 0.15-0.8MPa valve pressure range.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400S-10A the Right Choice?
Size between the 63mm bore (1559N push at 0.5MPa) and the 100mm bore (3927N push). This 80mm bore gives 2513N push and 2268N pull at 0.5MPa, peaking at 4021N push at the 0.8MPa valve limit. Confirm the AC220V terminal entry and PT threads suit your control panel. The rod retracts when the coil is energised; reposition the valve to extend on signal. The valve routes air but does not lock the piston, so 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 SAUF80X400S-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 (3/8" port, Cv 1.68, 4 cycles/s max). Coil is AC220V with terminal entry. Size forces within the valve's 0.15-0.8MPa operating window, as the assembled unit cannot use the cylinder body's 1.0MPa maximum rating.
By default, the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The built-in valve only routes air; it is not a load lock. On air loss, the piston drifts, so you must add an external rod lock or pilot-operated check valve to hold a suspended load.
