Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X250-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X250-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 250mm 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 SAUF50X250-06A
The SAUF50X250-06A is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve mounted 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. The bore sets the 1/4" cylinder port and M16x1.5 rod thread.
Operating within the valve's 0.15-0.8 MPa window, it delivers 982 N push at 0.5 MPa. The 1/8" valve port yields a 14 mm2 flow (Cv 0.78) with a 5 cycle/s limit. The AC220V terminal coil is IP65 rated. Compute your load: safe working load is ~589 N (60% of the 982 N figure), allowing a ~50 kg vertical lift with a 2:1 margin. This SKU lacks a magnet, so it cannot take 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 SAUF50X250-06A Is Used
Diverter Gate Actuation
Decentralized sorting lines use this self-switching cylinder to push diverter gates, cutting tubing runs to a central manifold.
Independent Clamp Stations
Multi-station fixture beds deploy one SAUF per clamp, triggering each independently via a single coil signal without extra valves.
Machine Tool Loading
Automated loading arms benefit from the compact profile and integrated valve, fitting tight cells while simplifying air plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X250-06A the Right Choice?
Size by checking both neighbours: the 40 mm bore gives 628 N push at 0.5 MPa, while the 63 mm bore yields 1559 N. This 50 mm bore provides 982 N push and 825 N pull at 0.5 MPa. Confirm the AC220V terminal entry and PT threads suit your control panel. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, never 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. For this 250 mm stroke, ensure side-load guidance to prevent rod binding.
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 SAUF50X250-06A FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s max) driven by an AC220V terminal coil. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
This specific SKU has no magnet (-S omitted), so it cannot accept a magnetic switch. Additionally, the built-in valve only routes air; it is not a lock. The rod will drift on air loss, so install an external rod lock or pilot-operated check valve for load holding.
