Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X225-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X225-06A 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 SAUF50X225-06A
The SAUF50X225-06A is a double-acting profile cylinder with a built-in AirTAC 4M 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot in decentralized installations. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It uses a Ø20 mm piston rod with an M16x1.5 thread, a 1/4" cylinder port, and 21 mm adjustable cushions.
This 50 mm bore generates 982 N push and 825 N pull at 0.5 MPa, operating within the valve's 0.15-0.8 MPa range. The integrated 4M210-06 valve has a 1/8" port, Cv 0.78, and handles 5 cycles/sec. The AC220V terminal-entry coil is IP65 rated. Computed buyer insight: safe working load is roughly 589 N, and vertical lift capacity is about 50 kg with a 2:1 margin. Note this SKU lacks a magnet, so 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 SAUF50X225-06A Is Used
Diverter Gate Actuation
Drives a sorting flap directly at the conveyor lane. The integrated valve removes the need to run long control lines back to a central manifold, speeding up installation.
Independent Clamping Station
Powers a single clamping head in a multi-station fixture. One coil signal controls the clamp, freeing up manifold slots for other actuators on the machine.
Decentralized Press Ram
Executes a short pressing stroke in a standalone sub-assembly. The 4M210 valve switches locally, ensuring rapid response without flow losses from remote tubing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X225-06A the Right Choice?
Size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. At 0.5 MPa this 50 mm bore pushes 982 N; if you need less force consider the 40 mm bore (628 N), or step up to the 63 mm bore (1559 N) for more power. Confirm the AC220V terminal entry matches your supply. The rod retracts when energised, but you can reconfigure it to extend by repositioning the valve. Because the 225 mm stroke exceeds 300 mm, provide external side-load guidance. The valve routes air but does not hold the load on pressure loss—add an external rod lock or pilot-operated check valve for suspended loads. Without a -S suffix, this SKU cannot accept a sensor.
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 SAUF50X225-06A 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/sec) driven by an AC220V terminal-entry coil. Size the force within the valve's 0.15-0.8 MPa operating window; do not use the 1.0 MPa cylinder body rating for the assembled unit.
Yes, you can reposition the valve to make the rod extend when energised. The valve only routes air; it is not a load lock. If air pressure drops, the piston will drift. For suspended or held loads, install an external rod lock or pilot-operated check valve.
