Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175S-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 175mm stroke and a built-in 4M210-08 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 SAUF50X175S-08A
The SAUF50X175S-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 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. The bore sets the 1/4" cylinder port, while the valve port is also 1/4".
Operating within the 0.15-0.8 MPa valve window, it delivers 982 N push at 0.5 MPa. The AC220V terminal-entry coil is IP65 rated. With a 16 mm2 flow (Cv 0.89) and 5 cycles/s frequency, the safe working load is roughly 589 N, enabling a 50 kg vertical lift with a 2:1 margin. The S suffix denotes a piston magnet for CMSG/DMSG/EMSG switches.

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 SAUF50X175S-08A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving manifold space.
Inline Diverters
Perfect for conveyor sorting gates that require rapid, localized switching without running long tubing back to a central valve bank.
Package Stops
Deployed as independent package stops in high-speed logistics lines, leveraging the 5 cycles/s frequency for precise timing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175S-08A the Right Choice?
Size by force: this 50 mm bore pushes 982 N at 0.5 MPa, sitting between the 40 mm (628 N) and 63 mm (1559 N) options. Always size within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry suits your control panel. The rod retracts when energised; reposition the valve to reverse this to extend-when-energised. The built-in valve routes air and is not a lock, so add an external rod lock or pilot-operated check valve to hold loads securely. For this 175 mm stroke, side-load is minimal, but always guide the load for strokes over 300 mm.
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 SAUF50X175S-08A FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s) driven by an AC220V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
By default, the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve on the cap. This self-switching design means no remote valve is needed, saving tubing and installation time.
