Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225-08B 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 SAUF80X225-08B
The SAUF80X225-08B 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 80mm bore delivers 2513N push and 2268N pull at 0.5MPa. The cylinder body rates to 1.0MPa, but the assembled unit operates strictly in the 0.15-0.8MPa valve window.
This decentralized design uses a DC24V terminal entry coil (IP65, response <=0.05s). The integrated valve provides 25mm2 flow (Cv 1.4) at a 1/4" port, cycling up to 4 times per second. For sizing, the safe working load is roughly 1508N (60% of the 0.5MPa push force), translating to a vertical lift capacity of about 128kg with a 2:1 margin. The 3/8" cylinder port and Ø10xØ6.5 PU tubing match the bore requirements.

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 SAUF80X225-08B Is Used
Decentralized Diverters
Mount directly on a conveyor diverter arm. The integrated valve eliminates long tube runs back to a central manifold, reducing response delays.
Independent Lift Stations
Drive individual lifting stops in a multi-stage warehouse sorter. One DC24V signal per actuator simplifies control wiring and saves manifold space.
Machine Tool Clamping
Actuate standalone clamping blocks on a large machining bed. The self-contained 4M310-08 valve keeps plumbing local to the clamp.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225-08B the Right Choice?
Size this 80mm bore against the neighbouring 63mm (1559N push @0.5MPa) and 100mm (3927N push @0.5MPa) options to match your load. The safe working load is approximately 1508N. Confirm the DC24V terminal entry and PT thread meet your electrical specs. By default the rod retracts when the coil is energised; reposition the valve to switch to extend-when-energised. Because the 225mm stroke exceeds 300mm, ensure external side-load guidance to prevent rod damage. The built-in valve routes air but does not lock the load; on air loss the piston drifts and the 28mm cushions only decelerate near stroke end. Add an external rod lock or pilot-operated check valve for held loads. This SKU lacks a magnet (-S) and cannot accept magnetic switches.
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 SAUF80X225-08B FAQ
It delivers 2513N push and 2268N pull at 0.5MPa. The built-in valve is a 4M310-08 (5/2 solenoid) with a 1/4" port, Cv 1.4, and 25mm2 flow. The coil is DC24V with terminal entry. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the 0.15-0.8MPa valve window. The cylinder port is 3/8".
No. The built-in valve only routes air; it is not a locking mechanism. If air is lost or the valve is centered, the piston will drift. The 28mm adjustable cushions only decelerate the piston near stroke end. For load holding, install an external rod lock or pilot-operated check valve.
