Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175-06A 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 SAUF50X175-06A
The SAUF50X175-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 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. This 50mm bore uses a 1/4" cylinder port, a M16x1.5 rod thread, and 21mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers 982N push and 825N pull at 0.5 MPa. The integrated 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and handles 5 cycles/sec. The AC220V terminal-entry coil is IP65 rated. For sizing, the safe working load is roughly 589N, and vertical lift is about 50kg 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 SAUF50X175-06A Is Used
Decentralized Clamping
Ideal for distributed clamping stations where running a single AC220V signal to each actuator saves tubing and manifold space.
Inline Diverting
Provides independent diverting on a conveyor line, using the built-in 4M210-06 valve to switch the 50mm bore without a remote valve bank.
Compact Part Ejection
Fits into tight machine frames for part ejection, leveraging the shorter profile barrel and 1/4" cylinder port for responsive action.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175-06A the Right Choice?
Size by checking both neighboring bores: the 40mm bore yields 628N push at 0.5 MPa, while the 63mm bore provides 1559N, compared to this 50mm bore's 982N. Confirm the AC220V terminal entry and PT threads meet your control specs. Default action retracts the rod when energized, but repositioning the valve switches it to extend-when-energized. Always size force 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; for load holding on air loss, add an external rod lock or pilot-operated check valve. Since the 175mm stroke is under 300mm, side-load guides are less critical but still advised for rigid mounting.
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 SAUF50X175-06A FAQ
It delivers 982N push and 825N pull at 0.5 MPa using a built-in 4M210-06 valve (1/8" port, Cv 0.78, 5 cycles/sec). The AC220V terminal-entry coil runs on the 0.15-0.8 MPa valve window. Never size the assembled unit using the 1.0 MPa cylinder body rating.
No. The built-in valve routes air and is not a lock, so the piston drifts on air loss; add an external rod lock or pilot-operated check valve for holding. Also, this specific SKU lacks a magnet and cannot accept a magnetic sensor.
