Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125S-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125S-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 SAUF63X125S-10B
The SAUF63X125S-10B 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 unit of the same bore. It features a 63mm bore, 125mm stroke, and a built-in piston magnet for CMSG/DMSG/EMSG switches.
Operating within the valve's 0.15-0.8 MPa window, it delivers a 1559 N push force at 0.5 MPa. The integrated valve has a 3/8" port, Cv 1.68 flow, and handles up to 4 cycles/sec. The cylinder body itself rates to 1.0 MPa, but the assembled unit is limited by the valve. For sizing, the safe working load is roughly 935 N (60% of the 0.5 MPa push), and it can vertically lift 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-10B Is Used
Decentralized Clamping Station
Ideal for a machining cell where each clamping actuator switches itself via one DC24V signal, skipping a central manifold and cutting tubing runs.
Independent Diverter Gate
Perfect for a conveyor diverter that needs standalone operation. The integrated 4M310 valve responds in under 0.05s for rapid package routing.
Compact Vertical Lift
Suited for a localized vertical lift in a storage module. It safely handles around 79kg with a 2:1 margin at 0.5 MPa without needing remote valves.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125S-10B the Right Choice?
When sizing, compare neighboring bores: the 50mm bore offers 982 N push at 0.5 MPa, while the 80mm provides 2513 N. This 63mm bore gives 1559 N push and 1402 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT thread meet your electrical specs. The rod retracts when energized by default, but you can reposition the valve to extend on energization. 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 safely. For this 125mm stroke, side-load is minimal, but for strokes over 300mm, use SC-series mounting accessories and guide rails to prevent rod 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 SAUF63X125S-10B FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa, reaching 2494 N push at 0.8 MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, max 4 cycles/sec) running on DC24V. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa range.
By default, the rod retracts when the coil is energized. You can reconfigure it to extend on energization simply by repositioning the built-in valve. Because the valve only routes air, use an external rod lock or pilot-operated check valve if you need to hold a load during air loss.
