Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X800-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X800-08A 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 SAUF63X800-08A
The SAUF63X800-08A 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 is shorter than an ISO 15552 cylinder of the same bore. This 63mm bore uses a 3/8" cylinder port and a 1/4" valve port.
The integrated valve flows 25 mm2 (Cv 1.4) at up to 4 cycles/s. It operates at 0.15-0.8 MPa, so size force within that window rather than the 1.0 MPa cylinder body rating. At 0.5 MPa it pushes 1559 N and pulls 1402 N. The computed safe working load is about 935 N, allowing a vertical lift of roughly 79 kg with a 2:1 margin. The AC220V terminal coil is IP65 rated. Since this 800mm stroke SKU lacks a magnet, 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 SAUF63X800-08A Is Used
Divert Gate Actuation
Decentralized diverters on a packaging line benefit from the one-signal valve, removing long tube runs back to a central manifold.
Vertical Lift Station
Lifts loads up to 79kg using the 63mm bore, where the integrated 4M310 valve provides fast 4 cycle/s shifting without extra plumbing.
Long-Stroke Material Pusher
Pushing parts 800mm along a machine bed is simplified by the cap-mounted valve, keeping control wiring local to the actuator.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X800-08A the Right Choice?
Size this 63mm bore against its neighbours: the 50mm pushes 982 N and the 80mm pushes 2513 N at 0.5 MPa. This model delivers 1559 N push at 0.5 MPa within the 0.15-0.8 MPa valve window. Confirm the AC220V terminal entry suits your control panel. The rod retracts when the coil is energised; reposition the valve 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 a load. For this 800mm stroke, use external guides 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 SAUF63X800-08A FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 4 cycles/s). The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window. The coil is AC220V with a terminal entry.
The valve routes air and is not a load lock, so the piston drifts on air loss; add an external rod lock or pilot-operated check valve to hold a load. The rod retracts by default when the coil is energised, but you can reposition the valve to extend-when-energised.
