Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X250S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X250S-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 SAUF50X250S-06A
The SAUF50X250S-06A is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One coil signal drives the cylinder, eliminating remote plumbing and saving a manifold slot. The 50mm bore pushes 982N at 0.5MPa within the 0.15-0.8MPa valve operating window. The bore dictates a 1/4" cylinder port and M16x1.5 rod thread.
This unit features a 4M210-06 valve with a 1/8" port, 14mm2 flow (Cv 0.78), and 5 cycles/sec. The AC220V terminal-entry coil is IP65 rated. The -S suffix provides a piston magnet for CMSG/DMSG/EMSG switches. Computed buyer insight: safe working load is ~589N (60% of the 982N push at 0.5MPa), allowing a vertical lift of ~50kg 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 SAUF50X250S-06A Is Used
Decentralized Clamping
Ideal for a multi-station machining line where each clamping point needs an independent AC220V signal without running long tubing back to a central manifold.
Inline Diverter Gate
Perfect for a conveyor sorting system, using the built-in 4M210 valve to actuate a 250mm stroke diverter arm directly at the lane without extra plumbing.
Independent Pusher Station
Suits a decentralized packaging line push-off, saving manifold space by switching the 50mm bore directly from its own coil for localized product handling.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X250S-06A the Right Choice?
Size against the 63mm bore (push 1559N at 0.5MPa) or the 40mm bore (push 628N at 0.5MPa) depending on load limits. Confirm the AC220V terminal entry and PT threads. The cylinder body rates to 1.0MPa, but size force strictly within the 0.15-0.8MPa valve window. The rod retracts when energised; reposition the valve to reverse this. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold loads. For this 250mm stroke, use side-load guides to prevent rod bending.
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 SAUF50X250S-06A FAQ
It delivers 982N push and 825N pull at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) with an AC220V terminal-entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within a 0.15-0.8MPa window.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The valve only routes air; it is not a load lock. For load holding on air loss, install an external rod lock or pilot-operated check valve.
