Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125S-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125S-10A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 125mm stroke and a built-in 4M310-10 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 SAUF63X125S-10A
The SAUF63X125S-10A is a double-acting profile cylinder with a built-in AirTAC 4M310 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 cylinder of the same bore. It features a piston magnet for CMSG/DMSG/EMSG switches.
Operating within the 0.15-0.8 MPa valve window, it delivers a 1559 N push force at 0.5 MPa. The 3/8" valve port yields a Cv of 1.68 and supports 4 cycles/sec. The bore dictates a 3/8" cylinder port with a PT thread. For sizing, the safe working load is roughly 935 N, allowing a vertical lift of about 79 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 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 SAUF63X125S-10A Is Used
Decentralized Clamping
Ideal for large machining cells where each clamping station switches itself via one AC220V signal, skipping a central valve manifold.
Independent Diverters
Mount directly on conveyor divert arms. The built-in 4M310 valve routes air locally, cutting tubing runs back to a control panel.
Compact Stop Gates
Fits tight warehouse conveyor frames. The profile barrel saves space while the integrated valve simplifies electrical control.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125S-10A the Right Choice?
Size this 63 mm bore against the 50 mm (982 N push) and 80 mm (2513 N push) neighbors at 0.5 MPa. Confirm the AC220V terminal entry and PT threads. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve only routes air; add an external rod lock or pilot-operated check valve to hold loads. For this 125 mm stroke, standard guides handle side loads, but add robust guidance for strokes over 300 mm.
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 SAUF63X125S-10A FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, 4 cycles/sec). It runs on AC220V via terminal entry. Size force within the 0.15-0.8 MPa valve operating window, as the assembled unit cannot use the 1.0 MPa cylinder body rating.
Yes. By default the rod retracts when energised, but you can reposition the built-in valve to make it extend on signal. This self-switching design means no remote valve is needed, though the valve only routes air and will not hold the load without an external check valve.
