Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450S-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 SAUF80X450S-08B
The SAUF80X450S-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. The bore dictates a 3/8" cylinder port and an M20x1.5 rod thread.
It integrates a 4M310-08 valve (1/4" port, Cv 1.4, 4 cycles/s max) with a DC24V terminal entry coil (IP65, response <=0.05s). The cylinder body rates to 1.0 MPa, but the assembled unit operates strictly at 0.15-0.8 MPa. At 0.5 MPa it pushes 2513 N and pulls 2268 N. The computed safe working load is roughly 1508 N, translating to a vertical lift capacity of about 128 kg with a 2:1 margin. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.

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 SAUF80X450S-08B Is Used
Decentralized Diverters
Drives individual lane diverters on a conveyor network directly from one coil signal, removing the need for a massive central valve manifold and long tubing runs.
Vertical Lift Stations
Lifts pallets or totes in localized warehouse zones using the 128kg vertical lift capacity, keeping the pneumatic installation compact and close to the motion point.
Independent Clamping Fixtures
Powers standalone clamping actuators across a large machining cell, allowing each fixture to switch itself locally without complex air routing back to a control panel.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450S-08B the Right Choice?
Size by checking both neighboring bores: the 63mm bore offers 1559 N push at 0.5 MPa, while the 100mm bore provides 3927 N. This 80mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa. Always size force within the built-in valve's 0.15-0.8 MPa window, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT threads meet your specs. The rod retracts when the coil is energized; reposition the valve to switch to extend-when-energized. Because the 450mm stroke exceeds 300mm, add external guides to prevent rod bending and side-load wear. The valve only routes air; it is not a load lock, so install an external rod lock or pilot-operated check valve to hold loads safely.
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 SAUF80X450S-08B FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa, reaching 4021 N push at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/s). The coil is DC24V with a terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
No, the built-in valve only routes air and is not a lock. The rod retracts by default when energized, but you can reposition the valve to extend when energized. For load holding on air loss, you must add an external rod lock or a pilot-operated check valve.
