Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X250-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X250-10A 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 SAUF80X250-10A
The SAUF80X250-10A 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 directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features an 80mm bore, 250mm stroke, and a 3/8" cylinder port.
This model pushes 2513N and pulls 2268N at 0.5MPa. The integrated 4M310-10 valve has a 3/8" port, Cv 1.68 flow, and handles 4 cycles/sec. The cylinder body rates to 1.0MPa, but size force within the valve's 0.15-0.8MPa window. For a safe working load, budget around 1508N (60% of the 0.5MPa push), which yields a 128kg vertical lift with a 2:1 margin. The AC220V terminal coil is IP65 rated. Since this SKU lacks the -S magnet suffix, it cannot take a magnetic switch.

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 SAUF80X250-10A Is Used
Decentralized Diverters
Drives package diverters directly at the conveyor lane without routing air lines back to a central manifold, simplifying machine layout.
Independent Clamp Stations
Powers individual clamping actuators across a large assembly fixture using a single coil signal per station, reducing tubing complexity.
Localized Stopper Gates
Controls pallet stop gates in high-density storage zones, saving manifold slots and accelerating installation time.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X250-10A the Right Choice?
When sizing, compare both ways: a 63mm bore neighbor offers 1559N push at 0.5MPa, while a 100mm bore gives 3927N. This 80mm bore provides 2513N push at 0.5MPa. Confirm the AC220V terminal entry and PT threads meet your control specs. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size within the 0.15-0.8MPa valve limit, never the 1.0MPa cylinder body rating. The integrated valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 250mm stroke, ensure side-load guidance to prevent rod bending.
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 SAUF80X250-10A FAQ
It generates 2513N push and 2268N pull at 0.5MPa, reaching 4021N at 0.8MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, 4 cycles/sec max). It uses an AC220V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
Yes, you can reposition the valve on the cap to switch the action to extend-when-energized. The valve only routes air; it is not a load lock. If air is lost, the piston drifts and the 28mm cushions only decelerate near stroke end. Use an external rod lock or pilot-operated check valve for load holding.
