Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X800S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X800S-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 SAUF63X800S-08B
The SAUF63X800S-08B is a double-acting profile-type 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. It features a 63mm bore, 800mm stroke, and a built-in piston magnet for CMSG/DMSG/EMSG switches.
The integrated valve supplies 1/4" ports with a 25 mm2 flow (Cv 1.4) and handles up to 4 cycles per second. The cylinder body rates to 1.0 MPa, but the assembled unit operates within the valve's 0.15-0.8 MPa window. At 0.5 MPa it delivers 1559 N push and 1402 N pull. A practical computed insight: safe working load is roughly 935 N (about 60% of the 0.5 MPa push), allowing a vertical lift of approximately 79 kg 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 SAUF63X800S-08B Is Used
Sorting Diverter
Decentralized package sorting where one coil signal per actuator removes the need for a central manifold, speeding up installation along the conveyor.
Long-Stroke Gate
Machine guarding gate that uses the 800mm stroke and built-in valve to simplify plumbing while providing reliable 1559 N push force.
Vertical Lift Station
Lifting station utilizing the 79 kg vertical lift capacity, relying on the integrated 4M310 valve to save space and tubing in tight racking aisles.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X800S-08B the Right Choice?
When sizing, compare neighboring bores: the 50mm bore yields 982 N push while the 80mm bore yields 2513 N push at 0.5 MPa. This 63mm unit provides 1559 N push. Confirm the DC24V terminal entry coil and PT thread before ordering. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Because the 4M310 valve routes air, it is not a load lock; add an external rod lock or pilot-operated check valve to hold a load safely. 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 SAUF63X800S-08B FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa, reaching 2494 N push at 0.8 MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port, 25 mm2 flow (Cv 1.4), and a DC24V terminal entry coil. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
Yes. The default action retracts the rod upon energizing, but you can reconfigure it to extend-when-energized simply by repositioning the valve. This decentralized design means one coil signal drives the cylinder without a remote valve, saving manifold slots and tubing.
