Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X800-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X800-08B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 800mm 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 SAUF63X800-08B
The AirTAC SAUF63X800-08B is a double-acting profile cylinder with a built-in 4M310-08 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 63mm bore uses a 3/8" air port, M16x1.5 rod thread, and 21mm adjustable cushions.
Operating in the 0.15-0.8 MPa valve window, it delivers 1559N push at 0.5 MPa. A safe working load is roughly 935N, allowing a vertical lift of about 79kg with a 2:1 margin. The 1/4" valve port gives 25mm2 flow (Cv 1.4) at up to 4 cycles/s. This DC24V terminal-entry coil is IP65 rated. Since this 800mm SKU lacks the S suffix, 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 SAUF63X800-08B Is Used
Long-stroke diverters
Drives 800mm sorting gates on conveyor lines directly from one DC24V signal without routing long tubing back to a central manifold.
Vertical lifting arms
Lifts 79kg loads in decentralized warehouse modules, using the integrated 4M310-08 valve to save cabinet space.
Machine tool doors
Opens heavy machine tool enclosures, relying on the 21mm adjustable cushions to decelerate the rod at stroke ends.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X800-08B the Right Choice?
Size force between the 0.15-0.8 MPa valve limits: this 63mm bore pushes 1559N at 0.5 MPa, sitting between the 50mm (982N) and 80mm (2513N) options. Confirm the DC24V terminal entry and PT threads suit your control panel. The rod retracts when the coil energises; reposition the valve to reverse this to extend-when-energised. The built-in valve routes air and is not a lock, so add an external rod lock or pilot-operated check valve to hold loads. For this 800mm stroke, use an external guide to prevent rod bending and side-load damage.
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 SAUF63X800-08B FAQ
It pushes 1559N and pulls 1402N at 0.5 MPa. The built-in valve is a 4M310-08 with a 1/4" port and Cv 1.4. The cylinder body rates to 1.0 MPa, but size force within the 0.15-0.8 MPa valve window. The coil is DC24V with terminal entry.
No. The built-in 5/2 valve routes air but is not a load lock. If air is lost or the valve is centered, the piston drifts. For vertical holding, install an external rod lock or pilot-operated check valve.
