Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125-10B 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 SAUF63X125-10B
The SAUF63X125-10B is a double-acting profile-type 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 features a 63mm bore, 125mm stroke, 3/8" air port, and M16x1.5 rod thread.
Operating strictly within the 0.15-0.8 MPa valve window, it delivers 1559 N push and 1402 N pull at 0.5 MPa. The integrated 4M310-10 valve has a 3/8" port, 30 mm2 flow (Cv 1.68), and cycles up to 4 times per second. The DC24V terminal coil offers IP65 protection. For sizing, the safe working load is roughly 935 N (60% of the 0.5 MPa push), translating to a 79 kg vertical lift with a 2:1 margin. Note this SKU lacks a magnet and cannot accept a sensor.

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 SAUF63X125-10B Is Used
Decentralized Clamping
Ideal for large machining cells where each clamping station switches itself via a single DC24V signal, skipping a central valve manifold.
Independent Diverters
Perfect for conveyor diverters requiring localized actuation, saving tubing runs back to a control panel and speeding up assembly.
Compact Package Stops
Suits warehouse stops on independent roller lanes, using the integrated 4M310 valve to minimize pneumatic plumbing complexity.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125-10B the Right Choice?
Size this 63mm bore against the neighboring 50mm (982 N push) and 80mm (2513 N push) options at 0.5 MPa. Confirm the DC24V terminal entry and PT thread meet your electrical specs. 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 built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads securely. For this 125mm stroke, side-load is minimal, but always guide the rod for strokes over 300mm.
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 SAUF63X125-10B 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/s max) running on DC24V. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
No, the built-in valve routes air and is not a lock; the piston drifts on air loss, so add an external rod lock or check valve for holding. Also, this specific SKU lacks a magnet (-S) and cannot accept a magnetic switch.
