Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X400S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X400S-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 SAUF50X400S-06A
The SAUF50X400S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 50mm bore delivers 982N push and 825N pull at 0.5MPa. The cylinder body rates to 1.0MPa, but size force within the integrated valve's 0.15-0.8MPa operating window.
This model includes a piston magnet for CMSG/DMSG/EMSG switches. The integrated 4M210-06 valve has a 1/8" port, Cv 0.78, and handles 5 cycles/sec. The cylinder port is 1/4". Based on the 982N push figure, the safe working load is roughly 589N, and it can vertically lift about 50kg with a 2:1 margin. It uses a 400mm stroke, so fit an external guide 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 SAUF50X400S-06A Is Used
Diverter Gate Control
Drives a decentralized lane diverter directly from the cylinder cap, removing the need to run long control tubes back to a central manifold.
Vertical Lift Station
Lifts a 50kg payload using the integrated 4M210 valve, saving manifold space while providing responsive local switching.
Component Pusher
Pushes parts on an assembly line with a 589N safe working load, utilizing the built-in magnet for end-of-stroke confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X400S-06A the Right Choice?
Size by checking both neighboring bores: the 40mm bore gives 628N push while the 63mm bore gives 1559N push at 0.5MPa. This 50mm bore provides 982N push, yielding a safe working load of 589N. Confirm the coil is AC220V with terminal entry. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Always size within the 0.15-0.8MPa valve limit. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. Because the 400mm stroke exceeds 300mm, add a side-load guide to protect the rod.
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 SAUF50X400S-06A FAQ
It features a 50mm bore, 400mm stroke, and a built-in 4M210-06 valve with 1/8" port and Cv 0.78. The AC220V coil runs at 3.5 VA with IP65 protection. Force is 982N push at 0.5MPa. Size within the 0.15-0.8MPa valve operating window, not the 1.0MPa cylinder body rating.
By default the rod retracts when the coil is energized. You can reconfigure it to extend when energized simply by repositioning the valve. This one-signal switching removes the need for a remote valve.
