Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 500mm 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 SAUF80X500-08A
The SAUF80X500-08A is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One AC220V coil signal drives the 500mm stroke, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. It features a 3/8 inch cylinder port, an M20x1.5 rod thread, and adjustable 28mm cushions.
The integrated valve supplies a 1/4 inch port with 25 mm2 flow (Cv 1.4) and switches up to 4 cycles per second. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window. At 0.5 MPa it pushes 2513 N and pulls 2268 N. A practical computed insight: the safe working load is about 1508 N (60% of the 0.5 MPa push force), and it can vertically lift roughly 128 kg with a 2:1 safety margin.

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 SAUF80X500-08A Is Used
Divert Gate Actuation
Drives a 500mm divert flap on a sorting line directly from one AC220V signal, removing the need to run long control tubing back to a central manifold.
Pallet Stopper Arm
Deploys a heavy stop arm at a packing station. The built-in 4M310-08 valve handles the flow locally, saving manifold space while providing 2513 N of push force.
Long-Stroke Material Pusher
Ejects parts from a machine bed using the full 500mm stroke. The integrated valve simplifies installation on moving subassemblies where flexible tubing is vulnerable.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500-08A the Right Choice?
When sizing, compare this 80mm bore against the 63mm and 100mm neighbors. The 63mm bore pushes 1559 N while the 100mm reaches 3927 N at 0.5 MPa. This 80mm unit provides 2513 N push force in that same 0.15-0.8 MPa valve window. Confirm your coil is AC220V with terminal entry and PT thread. Without the -S suffix, this SKU cannot take a magnetic switch. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. For the 500mm stroke, add external guides to prevent rod bending and side-load wear. The valve only routes air; it is not a lock. If you need to hold a load 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 SAUF80X500-08A FAQ
It generates 2513 N push and 2268 N pull at 0.5 MPa. The built-in valve is a 4M310-08 (1/4 inch port, Cv 1.4, 25 mm2 flow) running on AC220V. Although the cylinder body rates to 1.0 MPa, you must operate the assembled unit within the valve's 0.15-0.8 MPa range. The cylinder port is 3/8 inch.
Yes. The default action retracts the rod when energized, but you can reposition the valve to make it extend on signal. The valve only routes air; it is not a load lock. The piston will drift on air loss, so install an external rod lock or pilot-operated check valve if you need to hold a suspended load.
