Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X250-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X250-10B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 250mm 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 SAUF80X250-10B
The SAUF80X250-10B 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. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It features an 80mm bore, 250mm stroke, and a 3/8" cylinder port.
The integrated 4M310-10 valve has a 3/8" port, Cv 1.68 flow, and handles up to 4 cycles/sec. The DC24V coil offers IP65 protection with terminal entry. The cylinder body rates to 1.0 MPa, but the valve limits operation to 0.15-0.8 MPa. At 0.5 MPa it pushes 2513 N. Safe working load is about 1508 N, allowing a 128kg vertical lift with a 2:1 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 SAUF80X250-10B Is Used
Decentralized Diverters
Drives individual lane diverters directly at the conveyor edge without routing tubing back to a central manifold.
Independent Stack Gates
Controls separate stacker gates in a high-rise storage system using one DC24V coil signal per actuator.
Localised Clamp Arms
Powers standalone clamping arms on a large multi-station fixture, saving manifold slots and install time.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X250-10B the Right Choice?
Size by checking both neighboring bores: the 63mm bore yields 1559 N push at 0.5 MPa, while the 100mm bore yields 3927 N. This 80mm bore provides 2513 N push and 2268 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve window, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry coil meets your supply. The rod retracts when energized, but repositioning the valve changes it to extend-when-energized. Since this SKU lacks the S magnet suffix, it cannot accept a magnetic switch. The valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. For this 250mm stroke, ensure side-load guidance.
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 SAUF80X250-10B FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa, reaching 4021 N at 0.8 MPa. The built-in 4M310-10 valve has a 3/8" port, Cv 1.68, and runs on DC24V. The cylinder body rates to 1.0 MPa, but the assembled unit operates strictly within the 0.15-0.8 MPa valve window.
No. The built-in 5/2 valve routes air and is not a lock. The rod drifts on air loss. For a held load, add an external rod lock or pilot-operated check valve. Also, the rod retracts when energized by default, but you can reposition the valve to extend-when-energized.
