Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 175mm 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 SAUF50X175-06B
The SAUF50X175-06B is a double-acting profile-type cylinder with a built-in AirTAC 4M 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 makes it shorter than an ISO 15552 cylinder of the same bore. It uses a 1/4" cylinder port with an M16x1.5 rod thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 982 N push force at 0.5 MPa. The integrated 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and handles 5 cycles/sec. The DC24V coil offers IP65 protection with terminal entry. For sizing, the safe working load is roughly 589 N, and it can vertically lift about 50 kg 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 SAUF50X175-06B Is Used
Diverter Gate Actuation
Decentralized sorting lines use this self-switching cylinder to push diverter gates, saving manifold space and tubing runs across the conveyor.
Independent Clamping Stations
Ideal for machining cells where each clamping actuator needs its own direct coil signal without routing air back to a central valve bank.
Carton Flap Folding
Provides rapid 5 cycles/sec operation for packaging lines, folding flaps directly at the machine without extra remote plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175-06B the Right Choice?
When sizing, compare neighbouring bores: a 40 mm bore gives 628 N push at 0.5 MPa, while a 63 mm bore provides 1559 N. This 50 mm bore hits 982 N push and 825 N pull at 0.5 MPa. Confirm the DC24V coil and terminal entry suit your control system. Remember the assembled unit operates strictly in the 0.15-0.8 MPa range, not the 1.0 MPa cylinder body rating. The rod retracts when energised by default, but you can reposition the valve to extend on signal. Because this SKU lacks a magnet, it cannot take a magnetic switch. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold loads safely. For this 175 mm stroke, ensure 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 SAUF50X175-06B FAQ
It delivers 982 N push and 825 N pull at 0.5 MPa using a built-in 4M210-06 valve (1/8" port, Cv 0.78, 5 cycles/sec). The DC24V terminal-entry coil runs the assembled unit within a strict 0.15-0.8 MPa pressure window, despite the cylinder body rating of 1.0 MPa.
Yes. The default action retracts the rod upon energising, but you can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This decentralized design removes the need for a separate remote valve.
