Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 450mm 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 SAUF80X450-08B
The SAUF80X450-08B 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. This SKU uses terminal entry, PT threads, and has no magnet, so it cannot take a magnetic switch.
The integrated valve restricts operation to a 0.15-0.8 MPa window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it delivers 2513 N push and 2268 N pull. The 4M310-08 valve has a 1/4" port, Cv 1.4, and cycles up to 4 times per second. For sizing, the safe working load is roughly 1508 N, and vertical lift is about 128 kg with a 2:1 margin. The cylinder bore port is 3/8", and it uses Ø10xØ6.5 PU tube.

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 SAUF80X450-08B 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 Gate
Controls a 450 mm stroke stop gate in a decentralized warehouse zone, saving manifold space while providing 2513 N push force at 0.5 MPa.
Machine Guard Door
Opens and closes a large access door at up to 4 cycles per second using the integrated 4M310 valve without external plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450-08B the Right Choice?
Size this 80 mm bore against the neighboring 63 mm (1559 N push) and 100 mm (3927 N push) options at 0.5 MPa. The 450 mm stroke is well within the 1500 mm maximum but requires external guidance to prevent rod bending under side loads. Confirm the DC24V terminal coil and PT threads match your control scheme. The built-in valve limits operating pressure to 0.15-0.8 MPa. The valve routes air but does not lock the load; add an external rod lock or pilot-operated check valve for holding. The rod retracts when energized but can be reconfigured to extend by repositioning the 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 SAUF80X450-08B FAQ
It delivers 2513 N push and 2268 N pull at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec) running on DC24V. You must size the force within the valve's 0.15-0.8 MPa operating window, not the cylinder body's 1.0 MPa rating.
Yes, you can reconfigure the default retract action to extend-when-energised simply by repositioning the valve. 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 load.
