Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X80S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X80S-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 80mm stroke and a built-in 4M210-06 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 SAUF50X80S-06A
The SAUF50X80S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote valves and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It includes a piston magnet for switch sensing.
The 50mm bore delivers 982N push and 825N pull at 0.5MPa. The integrated 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and handles 5 cycles/sec. The cylinder body rates to 1.0MPa, but the valve limits operation to 0.15-0.8MPa. For sizing, the safe working load is roughly 589N, and vertical lift is about 50kg 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAUF50X80S-06A Is Used
Decentralized Clamping
Ideal for clamping stations on large machines where running tubing back to a central manifold is impractical, switching directly from one local signal.
Inline Diverting
Mount directly on a conveyor frame to actuate a diverter gate. The integrated valve minimizes pneumatic plumbing across the line.
Zone Stops
Perfect for independent stop gates in modular conveyor zones, saving manifold space and simplifying installation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X80S-06A the Right Choice?
Size by force: the 50mm bore gives 982N push at 0.5MPa, sitting between the 40mm (628N) and 63mm (1559N) bores. Confirm the AC220V terminal entry and 1/4" cylinder port. The 4M210-06 valve port is 1/8". Size all force within the 0.15-0.8MPa valve window, not the 1.0MPa cylinder rating. The rod retracts when energised; reposition the valve to extend on signal. The valve routes air and does not hold loads on air loss—add an external rod lock or pilot-operated check valve for holding. For this 80mm stroke, side-load guides are not strictly required but ensure correct alignment.
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 SAUF50X80S-06A FAQ
It features a 50mm bore, 80mm stroke, and a built-in 4M210-06 valve (1/8" port, Cv 0.78, 5 cycles/sec). The coil is AC220V with terminal entry. Push force is 982N and pull is 825N at 0.5MPa. Size within the 0.15-0.8MPa valve operating window.
By default, the rod retracts when the coil is energised. You can reconfigure it to extend when energised simply by repositioning the valve. This self-switching design means no remote valve is needed.
