Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X250-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X250-06B 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 SAUF50X250-06B
The SAUF50X250-06B is a double-acting profile-type cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the cylinder, 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.
It delivers 982N push and 825N pull at 0.5MPa. The integrated valve has a 1/8" port, 14mm2 flow (Cv 0.78), and handles 5 cycles/sec. The DC24V terminal coil is IP65 rated. Size force within the 0.15-0.8MPa valve window, not the 1.0MPa cylinder body rating. Computed buyer insight: safe working load is ~589N (60% of the 0.5MPa push), allowing a ~50kg vertical lift 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 SAUF50X250-06B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate. One DC24V signal actuates the 50mm bore to push cartons, removing the need to trace tubing back to a central manifold.
Independent Clamping Station
Ideal for a standalone clamping fixture delivering 982N push at 0.5MPa. The built-in 4M210 valve simplifies installation and saves manifold space.
Machine Door Actuation
Drives an access door on a large machine. The compact profile cylinder and integrated valve keep the installation tidy without external plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X250-06B the Right Choice?
Size against the 63mm bore (1559N push at 0.5MPa) or the 40mm bore (628N push) depending on your load. This 50mm bore provides 982N push at 0.5MPa. Confirm the DC24V terminal entry and PT threads suit your control system. The cylinder body rates to 1.0MPa, but the assembled SAUF must operate within the 0.15-0.8MPa valve range. The rod retracts when the coil is energised; reposition the valve to reverse this to extend-when-energised. The valve routes air and is not a load lock—add an external rod lock or pilot-operated check valve to hold a load. For this 250mm stroke, ensure side-load guidance. This SKU lacks a magnet (-S) and cannot take a magnetic switch.
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 SAUF50X250-06B 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 max) with a DC24V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the 0.15-0.8MPa valve window.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The 5/2 valve only routes air; it is not a load lock. To hold a load on air loss, install an external rod lock or pilot-operated check valve.
