Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X75S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X75S-08B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 75mm stroke and a built-in 4M310-08 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 SAUF63X75S-08B
The SAUF63X75S-08B is a double-acting profile cylinder with a built-in AirTAC 4M310-08 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 unit of the same bore. This 63mm bore includes a 3/8" air port, an M16x1.5 rod thread, and an S-suffix piston magnet for CMSG/DMSG/EMSG switches.
Operating within the valve's 0.15-0.8 MPa window, it delivers 1559N push at 0.5 MPa. The 1/4" port valve flows 25mm2 (Cv 1.4) at up to 4 cycles/s. The DC24V terminal coil is IP65 rated. For sizing, a safe working load is roughly 935N (60% of the 0.5MPa push), equating to a 79kg vertical lift 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 SAUF63X75S-08B Is Used
Modular Clamp Stations
Decentralized clamping on machining cells uses one coil signal per actuator, cutting tubing runs and freeing manifold space.
Inline Diverters
A self-switching 63mm bore handles package routing gates directly at the conveyor edge without a remote valve bank.
Vertical Lift Stops
The built-in magnet and compact profile fit tight palletiser frames, lifting 79kg loads with a 2:1 safety margin.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X75S-08B the Right Choice?
Size against the 0.5MPa push (1559N) and pull (1402N) figures, stepping down to a 50mm bore (982N push) for lighter loads or up to an 80mm bore (2513N push) for heavier tasks. The cylinder body rates to 1.0MPa, but the assembled unit is strictly limited to the built-in valve's 0.15-0.8MPa range. Confirm the DC24V terminal entry and PT threads suit your control panel. The rod retracts when energised by default; reposition the valve to extend on signal. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. For strokes over 300mm, use SC-series mounts and guide rails to manage side loads.
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 SAUF63X75S-08B FAQ
It pushes 1559N and pulls 1402N at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25mm2 flow) running on a DC24V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
No, the 5/2 valve routes air but does not lock the piston. The rod retracts when energised by default, but you can reposition the valve to extend on signal. For fail-safe load holding, install an external rod lock or pilot-operated check valve.
