Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450-10B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 450mm 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 SAUF80X450-10B
The SAUF80X450-10B 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 large machines. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore.
It pushes 2513 N and pulls 2268 N at 0.5 MPa. The integrated valve flows 30 mm2 (Cv 1.68) via a 3/8" port, cycling up to 4 times per second. Computed buyer insight: safe working load is roughly 1508 N, allowing a 128 kg vertical lift with a 2:1 margin. The cylinder port is 3/8" and uses PT threads.

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 SAUF80X450-10B Is Used
Divert Gate Actuation
Drives a heavy diverter on a packaging line directly from one coil signal, removing the need to route tubing back to a central manifold.
Pallet Stopper Control
Raises and lowers a 450mm stop gate in a high-throughput warehouse, relying on the built-in 4M310 valve for rapid 4 cycle/s response.
Press Ejection System
Ejects parts from a large press using decentralized switching, saving manifold space while delivering 2513 N push force at 0.5 MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450-10B the Right Choice?
Size force between the 0.15-0.8 MPa valve window, never the 1.0 MPa cylinder body rating. The 80mm bore yields 2513 N push at 0.5 MPa; step down to a 63mm bore (1559 N) for lighter loads or up to 100mm (3927 N) for heavier tasks. This DC24V terminal entry coil cannot take a sensor since it lacks the S suffix. The 450mm stroke requires external guides to prevent rod bending under side loads. The valve routes air but is not a lock; add an external rod lock or pilot-operated check valve to hold loads on air loss.
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 SAUF80X450-10B FAQ
It delivers 2513 N push and 2268 N pull at 0.5 MPa, reaching 4021 N at 0.8 MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, 30 mm2 flow) running on DC24V. Size the assembled unit strictly within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
By default the rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. The 5/2 valve only routes air; it is not a load lock. The piston will drift on air loss, so fit an external rod lock or pilot-operated check valve for suspended loads.
