Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175S-08B 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-08B
The AirTAC SAUF50X175S-08B is a double-acting profile cylinder with a built-in 4M210 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 and M16x1.5 rod thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 982 N push at 0.5 MPa. A computed buyer insight: safe working load is roughly 589 N, allowing a 50 kg vertical lift with a 2:1 margin. The 4M210-08 valve has a 1/4" port, 16 mm2 flow (Cv 0.89), and 5 cycles/sec. The DC24V coil offers IP65 protection with a 0.05 s response. The S suffix adds 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-08B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station switches itself via one DC24V signal, skipping a central valve manifold.
Inline Divert Gate
Perfect for a conveyor diverter needing independent actuation; the built-in valve cuts tubing runs back to a main control panel.
Package Stopper
Suits a packaging line stop gate. The compact profile and self-contained switching simplify installation on tight machine frames.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175S-08B the Right Choice?
Size force between the 40 mm bore (628 N push) and 63 mm bore (1559 N push) at 0.5 MPa. This 50 mm bore provides 982 N push. Confirm the DC24V terminal entry matches your control circuit. The rod retracts when the coil is energised; reposition the valve to extend on energisation. Size pressure within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 175 mm stroke, ensure adequate side-load guidance.
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-08B FAQ
It delivers 982 N push and 825 N pull at 0.5 MPa. The built-in 4M210-08 valve has a 1/4" port, Cv 0.89, and runs on DC24V. Although the cylinder body rates to 1.0 MPa, size force within the 0.15-0.8 MPa valve operating window.
Yes. The default action retracts the rod when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This self-switching design removes the need for a remote valve.
