Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X350S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X350S-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 350mm 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 SAUF50X350S-06B
The SAUF50X350S-06B 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 makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/4 inch cylinder port, an M16x1.5 rod thread, and a piston magnet for position sensing.
Operating within the 0.15-0.8 MPa valve window, it delivers 982 N push force at 0.5 MPa. The 1/8 inch valve port yields a 14 mm2 flow (Cv 0.78) and cycles up to 5 times per second. The DC24V terminal coil is IP65 rated. For sizing, the safe working load is roughly 589 N, and it can vertically lift about 50 kg with a 2:1 margin. The 350 mm stroke requires external guidance to prevent rod bending.

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 SAUF50X350S-06B Is Used
Conveyor Diverter Gate
Uses one coil signal to actuate a 350 mm diverter arm directly at the conveyor, eliminating long tubing runs back to a central manifold.
Decentralized Pallet Stop
Mounts independently on a pallet line. The built-in 4M210-06 valve handles local stopping logic without consuming manifold space.
Component Pusher Station
Pushes parts using 982 N force at 0.5 MPa. The onboard valve enables fast 5 cycle/sec actuation right at the machining cell.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X350S-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 yields 1559 N. This 50 mm bore provides 982 N push and 825 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT threads suit your supply. The rod retracts when energized by default, but you can reposition the valve to extend on signal. Because the 350 mm stroke exceeds 300 mm, add external guides to handle side loads. The valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve.
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 SAUF50X350S-06B FAQ
It delivers 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (5/2 solenoid) with a 1/8 inch port, 14 mm2 flow (Cv 0.78), and a DC24V terminal coil. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
Yes. The default action retracts the rod when energized, but you can reconfigure it to extend-when-energized simply by repositioning the valve on the cap. This self-switching design means no remote valve is needed.
