Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175-08B 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 SAUF50X175-08B
The SAUF50X175-08B is a double-acting profile-type cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve mounted directly on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 50mm bore, 175mm stroke, 1/4" cylinder port, and an M16x1.5 rod thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 982 N push at 0.5 MPa. The DC24V terminal-entry coil offers IP65 protection and a 0.05 s response. The valve provides a 16 mm2 flow (Cv 0.89) and handles up to 5 cycles per second. For sizing, the safe working load is roughly 589 N, and it can vertically lift about 50 kg with a 2:1 margin. This SKU lacks a magnet and cannot accept 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 (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 SAUF50X175-08B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate to push packages, switching itself with one coil signal and cutting tubing runs back to a central manifold.
Independent Clamping Station
Ideal for a standalone clamping actuator on a large machine, saving a manifold slot while delivering 982 N of push force at 0.5 MPa.
Localized Pallet Stop
Installs inline as a pneumatic stop without extra plumbing, using its 4M210 valve to cycle up to 5 times per second for high-throughput lines.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175-08B the Right Choice?
Size by checking both neighboring bores: the 40mm bore yields 628 N push while the 63mm bore yields 1559 N at 0.5 MPa. This 50mm bore provides 982 N push and 825 N pull at 0.5 MPa, so select it if your load sits near that range. Confirm the DC24V terminal entry and PT thread match your supply. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 175mm stroke, side-load is minimal, but ensure adequate guidance for longer strokes.
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 SAUF50X175-08B 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/sec max) driven by a DC24V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, you must size force within the built-in valve's 0.15-0.8 MPa operating window.
Yes, the default action retracts the rod on signal, but you can reconfigure it to extend when energized by repositioning the valve. The valve only routes air; it is not a load lock. If you need to hold a load against air loss, install an external rod lock or pilot-operated check valve.
