Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X75S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X75S-08A 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-08A
The SAUF63X75S-08A is a double-acting profile cylinder with a built-in AirTAC 4M 5/2 solenoid valve on the cap. One coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
It carries a 4M310-08 valve (1/4 inch port, Cv 1.4, 4 cycles/s max) running on AC220V terminal entry. The cylinder body rates to 1.0 MPa, but the assembled unit operates strictly within the 0.15-0.8 MPa valve window. At 0.5 MPa it pushes 1559 N and pulls 1402 N. For sizing, a 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 bore sets the 3/8 inch cylinder port, while the PU tube is Ø8xØ5.

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-08A Is Used
Decentralized Clamping
Drives individual machining clamps directly from the cap valve, removing long tube runs back to a central manifold.
Inline Diverters
Powers sorting gates on a conveyor line using one AC220V signal per actuator for rapid localized routing.
Compact Stop Gates
Controls pallet stops in tight assembly cells where mounting a separate remote valve is impractical.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X75S-08A the Right Choice?
Size by checking both neighbours: the 50 mm bore pushes 982 N and the 80 mm bore pushes 2513 N at 0.5 MPa. This 63 mm bore provides 1559 N push, yielding a safe working load around 935 N. Confirm the AC220V terminal entry and PT threads suit your control panel. The cylinder body rates to 1.0 MPa, but you must size force within the 0.15-0.8 MPa valve limit. Default action retracts the rod when energised; reposition the valve to extend on energisation. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold a load. Stroke is 75 mm, meeting the 75 mm minimum for this bore, so no side-load guide is required.
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-08A FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa. The built-in valve is a 4M310-08 (1/4 inch port, Cv 1.4, max 4 cycles/s) running on AC220V terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly within the 0.15-0.8 MPa valve window.
Yes. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the built-in valve. This single-coil operation means no remote valve is needed, saving a manifold slot and tubing.
