Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 225mm 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 SAUF80X225-08A
The SAUF80X225-08A is a double-acting profile cylinder with a built-in AirTAC 4M310-08 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 80mm bore uses a 25mm rod, M20x1.5 thread, 3/8" cylinder port, and 28mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa range, it delivers 2513 N push force at 0.5 MPa. The 1/4" valve port provides 25 mm2 flow (Cv 1.4) at up to 4 cycles/sec. With an AC220V terminal entry coil (IP65, response <=0.05s), the safe working load is about 1508 N, enabling a 128 kg vertical lift with a 2:1 margin. This SKU lacks a magnet, so it cannot take a sensor.

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 SAUF80X225-08A Is Used
Diverter Gate Actuation
Decentralized sorting line diverter where the integrated valve eliminates long tube runs back to a central manifold, simplifying machine layout.
Pallet Stopper Control
Independent pallet stop station using one coil signal to drive the 80mm bore, saving manifold slots while providing 2513 N push force at 0.5 MPa.
Clamp Station Actuator
Isolated clamping mechanism on a large machine bed; the built-in 4M310-08 valve enables local control without adding complex remote plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225-08A the Right Choice?
Size by comparing 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 AC220V terminal entry and PT thread meet your control voltage. The rod retracts when the coil is energized, but you can reposition the valve to extend on energization. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads. For this 225mm stroke, ensure side-load guidance via SC-series mounts.
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 SAUF80X225-08A FAQ
It delivers 2513 N push and 2268 N pull at 0.5 MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port, Cv 1.4, and runs at max 4 cycles/sec. The AC220V terminal coil is IP65. You must size force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod when the coil is energized, but you can reposition the valve on the cap to extend when energized. Because the valve merely routes air, it is not a load lock; the piston will drift on air loss, so add an external rod lock for holding.
