Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X400-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X400-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 400mm 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 SAUF50X400-06A
The SAUF50X400-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One 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. This 50mm bore uses a 1/4" cylinder port and a 1/8" valve port.
Operating strictly within the 0.15-0.8 MPa valve window, it delivers 982N push at 0.5MPa. The safe working load is roughly 589N, enabling a 50kg vertical lift with a 2:1 margin. The AC220V terminal-entry coil is IP65 rated, and the valve flows 14mm2 (Cv 0.78) at up to 5 cycles/s. Without the -S suffix, this SKU 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 SAUF50X400-06A Is Used
Inline Diverter Gate
Decentralized sorting on a conveyor where one coil signal per gate saves tubing runs back to a central manifold.
Vertical Package Stop
Independent actuation for a 50kg package stop, leveraging the 982N push force at 0.5MPa with a safe 2:1 margin.
Machine Guard Door
Direct switching of a 400mm guard door, using the compact profile to save space and eliminating a remote valve bank.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X400-06A the Right Choice?
Size between the 40mm bore (628N push) and 63mm bore (1559N push) options, using the 0.5MPa figures as your baseline. This 50mm model pushes 982N and pulls 825N at 0.5MPa. Confirm the AC220V terminal entry matches your control voltage. The rod retracts when the coil is energised but can be reconfigured to extend-when-energised by repositioning the valve. Size force within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder body rating. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve for held loads. For the 400mm stroke, use external guides to prevent rod bending and side-load damage.
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 SAUF50X400-06A FAQ
It pushes 982N and pulls 825N at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s max) with an AC220V terminal coil. The cylinder body rates to 1.0MPa, but you must size force within the 0.15-0.8MPa assembled valve window.
No. The built-in valve routes air but is not a load lock. On air loss the piston drifts and the 21mm cushion only decelerates near stroke end. For a held load, add an external rod lock or pilot-operated check valve.
