Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125-10A 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 SAUF63X125-10A
The SAUF63X125-10A 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 makes it shorter than an ISO 15552 cylinder of the same bore. It uses a 3/8" air port, M16x1.5 rod thread, and 21mm adjustable cushions.
Driven by an AC220V terminal-entry coil (IP65, class B), the integrated 4M310-10 valve provides 30 mm2 flow (Cv 1.68) at up to 4 cycles per second. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window. At 0.5 MPa it pushes 1559 N and pulls 1402 N. For sizing, the safe working load is roughly 935 N, and it can vertically lift about 79 kg with a 2:1 margin. This SKU lacks a magnet, so it cannot take a magnetic switch.

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 SAUF63X125-10A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving manifold space and tubing runs.
Inline Diverting
Mounts directly on a conveyor diverter arm. The integrated 4M310 valve switches the 3/8" port rapidly at up to 4 cycles per second for high throughput.
Independent Lift Stations
Perfect for multi-station lift gates in a sorting hub. The self-contained AC220V valve eliminates the need to route long control lines back to a central island.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125-10A the Right Choice?
Size this 63mm bore against the neighbouring 50mm and 80mm options. At 0.5 MPa it delivers 1559 N push and 1402 N pull, sitting between the 50mm (982 N) and 80mm (2513 N) bores. Always size within the 0.15-0.8 MPa valve operating range, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry matches your supply. The rod retracts when the coil is energised; you can reposition the valve to extend-when-energised. Because this is a non-magnet SKU, magnetic sensing is impossible. The valve routes air but does not lock the piston, so add an external rod lock or pilot-operated check valve to hold a load. For this 125mm stroke, side-load is minimal, but for strokes over 300mm, add a guide to prevent binding.
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 SAUF63X125-10A FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa. The built-in valve is a 4M310-10 (5/2 solenoid) with 3/8" ports, Cv 1.68, and a 4 cycle/s limit. The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
Yes. The default action retracts the rod when the coil is energised, but you can reposition the valve on the cap to make it extend-when-energised. The valve only routes air; it is not a load lock. If air is lost, the piston drifts, so install an external rod lock or pilot-operated check valve for held loads.
