Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500S-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 500mm 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 SAUF50X500S-06A
The SAUF50X500S-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. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. It features a piston magnet for CMSG/DMSG/EMSG switches.
The integrated 4M210-06 valve has a 1/8" port, Cv 0.78, and runs up to 5 cycles/sec. The cylinder bore uses a 1/4" air port with an M16x1.5 rod thread. Size force within the 0.15-0.8 MPa valve window, where push is 982 N and pull is 825 N at 0.5 MPa. Computed insight: safe working load is ~589 N (60% of [email protected]), allowing a vertical lift of ~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 SAUF50X500S-06A Is Used
Decentralized Conveyor Divert
Mounts directly at a lane diverter on a long conveyor. One AC220V signal actuates the 500 mm stroke, needing no remote valve manifold.
Packaging Pusher Station
Ideal for a standalone packaging pusher. The built-in 4M210 valve and 1/4" cylinder port handle the 50 kg vertical lift margin locally.
Machine Tool Loading
Loads parts into a CNC cell. The compact profile barrel and integrated switching simplify installation on a large machine frame.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500S-06A the Right Choice?
Size both ways: the 50 mm bore gives 982 N push at 0.5 MPa, sitting between the 40 mm (628 N) and 63 mm (1559 N) options. Confirm the AC220V terminal entry and PT thread. Default action retracts the rod when energised; reposition the valve to extend-when-energised. The cylinder body rates to 1.0 MPa but the assembled SAUF operates strictly at 0.15-0.8 MPa. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 500 mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF50X500S-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) running on AC220V. Although the cylinder body rates to 1.0 MPa, the assembled SAUF must operate within the 0.15-0.8 MPa valve window.
By default the rod retracts when energised, but you can reposition the valve to extend-when-energised. The 5/2 valve only routes air; it is not a load lock. If air is lost, the piston drifts. Use an external rod lock or pilot-operated check valve for load holding.
