Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900S-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 900mm 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 SAUF50X900S-06A
The SAUF50X900S-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 extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. The 1/4" cylinder port and M16x1.5 rod end handle robust tasks.
Operating within the valve's 0.15-0.8 MPa window, it delivers 982 N push force at 0.5 MPa. The integrated valve provides 1/8" porting with a Cv of 0.78 and cycles up to 5 times per second. The AC220V terminal coil is IP65 rated. With a 900 mm stroke, the -S suffix denotes a piston magnet for CMSG/DMSG/EMSG sensors. For sizing, the safe working load is roughly 589 N, allowing a vertical lift of about 50 kg with a 2:1 margin.

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 SAUF50X900S-06A Is Used
Long-Stroke Diversion
Decentralized 900 mm pusher on a conveyor line. The built-in 4M210 valve switches instantly from a single AC220V signal without routing tubing back to a central manifold.
Vertical Material Lift
Elevating 50 kg packages. The 50 mm bore provides sufficient thrust at 0.5 MPa, while the integrated magnet allows precise end-of-stroke detection via CMSG sensors.
Machine Guard Gate
Actuating a 900 mm safety gate. The compact profile cylinder saves space, and the IP65 coil ensures reliable switching in industrial environments.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900S-06A the Right Choice?
Size by comparing the 50 mm bore (982 N push at 0.5 MPa) against the 40 mm (628 N) and 63 mm (1559 N) neighbors to match your load. Confirm the AC220V terminal entry and PT threads suit your control panel. The default action retracts the rod when energized, but repositioning the valve extends it on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. For this 900 mm 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 SAUF50X900S-06A FAQ
It delivers 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) driven by an AC220V terminal coil. Although the cylinder body rates to 1.0 MPa, you must size force within the valve's 0.15-0.8 MPa operating window.
No. The built-in 5/2 valve routes air but does not lock the piston. On air loss the rod drifts and the 21 mm cushion only decelerates near stroke end. For vertical load holding, install an external rod lock or pilot-operated check valve. Note the default action retracts when energized, but you can reposition the valve to extend on signal.
