Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X80-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X80-08A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 80mm 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 SAUF63X80-08A
The SAUF63X80-08A 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 makes it shorter than an ISO 15552 cylinder of the same bore. It features a 3/8 inch cylinder port, an M16x1.5 rod thread, and adjustable cushions.
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 provides a 1.4 Cv flow at a 1/4 inch port, switching up to 4 cycles per second. For sizing, the safe working load is roughly 935 N, and it can vertically lift about 79 kg with a 2:1 margin. The AC220V terminal entry coil is IP65 rated. Note this SKU lacks the S suffix, so 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 SAUF63X80-08A Is Used
Decentralized Clamping
Ideal for large welding cells where each clamp actuates independently from a single AC220V signal, saving manifold space and tubing runs.
Inline Diverters
Provides rapid 4 cycle/s switching for package routing gates without routing air lines back to a central control panel.
Machine Guard Gates
Drives access doors on automated machinery directly, leveraging the compact profile to fit tight frame dimensions.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X80-08A the Right Choice?
Size this 63 mm bore against the neighboring 50 mm and 80 mm options. At 0.5 MPa it pushes 1559 N and pulls 1402 N. Always size force within the 0.15-0.8 MPa assembled valve range, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal coil and PT thread meet your specs. Default action retracts the rod when energized, but you can reposition the valve to extend on signal. Since this 80 mm stroke is below 300 mm, side-load guides are less critical. The built-in valve routes air but does not lock the piston; add an external rod lock or pilot-operated check valve to hold loads safely.
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 SAUF63X80-08A FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4 inch port and 1.4 Cv flow. The AC220V coil operates at 0.15-0.8 MPa, despite the cylinder body rating to 1.0 MPa. It switches up to 4 cycles per second.
No, the built-in valve only routes air and is not a load lock; the piston will drift without pressure. Add an external rod lock or pilot-operated check valve for holding. By default the rod retracts when the coil is energized, but you can reposition the valve to extend on signal.
