Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X225-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X225-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 225mm 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 SAUF50X225-06B
The AirTAC SAUF50X225-06B is a double-acting profile cylinder with a built-in 4M210 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. The bore sets the 1/4" cylinder port, while the valve port is 1/8".
Size force within the 0.15-0.8 MPa valve window, where it delivers 982 N push and 825 N pull at 0.5 MPa. This yields a safe working load of roughly 589 N, or a vertical lift of about 50 kg with a 2:1 margin. The 4M210-06 valve flows 14 mm2 (Cv 0.78) at up to 5 cycles per second. Because this SKU lacks the S suffix, it cannot take a magnetic switch.

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 SAUF50X225-06B Is Used
Diverter Gate Actuation
Decentralized sorting line diverter where the integrated valve mounts directly on the cylinder, cutting tubing runs to a central manifold.
Component Clamping Station
Independent clamping on a machining cell; one DC24V signal controls the clamp without dedicating a manifold slot to each actuator.
Machine Guard Pusher
Pushing parts on an assembly machine where local switching simplifies wiring and speeds up the 5 cycles per second actuation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X225-06B the Right Choice?
When sizing, compare neighboring 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 fits applications needing around 982 N push. Confirm the DC24V terminal entry and PT threads before ordering. The cylinder body rates to 1.0 MPa, but the assembled unit must operate in the 0.15-0.8 MPa valve range. The rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 225 mm stroke, use a guide to prevent side-load wear.
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 SAUF50X225-06B 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) running on a DC24V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly in the 0.15-0.8 MPa range.
By default the rod retracts when the coil is energised. You can reconfigure it to extend when energised simply by repositioning the valve. This local switching means no remote valve is needed, and the 1/4" cylinder port handles the main air flow.
