Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800-08A is a genuine double-acting profile-type cylinder with a Ø80mm 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 SAUF80X800-08A
The SAUF80X800-08A 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 valves and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. It uses a Ø25 mm rod with an M20x1.5 thread, a 3/8" cylinder port, and 28 mm adjustable cushions.
Operating in the 0.15-0.8 MPa valve window, it delivers 2513 N push at 0.5 MPa. The 1/4" valve port flows 25 mm2 (Cv 1.4) at up to 4 cycles/sec. This AC220V terminal-entry coil is IP65 rated. Since this 800 mm stroke lacks the -S magnet, it cannot take a sensor. Based on the 0.5 MPa push figure, the safe working load is about 1508 N, yielding a vertical lift capacity of roughly 128 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 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 SAUF80X800-08A Is Used
Pallet Divertor
Decentralized diverting arm on a high-speed conveyor. The integrated valve eliminates long tubing runs back to a central manifold, improving cycle response.
Vertical Lift Gate
Raising a 100 kg access gate. The 80 mm bore provides the necessary force, while the built-in 4M310 valve simplifies installation at the gate top.
Machine Guard Door
Opening a long sliding safety door. One coil signal drives the 800 mm stroke directly, saving manifold space and reducing plumbing complexity.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800-08A the Right Choice?
When sizing, compare neighboring bores: the 63 mm bore gives 1559 N push while the 100 mm bore gives 3927 N push at 0.5 MPa. This 80 mm unit provides 2513 N push and 2268 N pull at 0.5 MPa, sized strictly within the 0.15-0.8 MPa valve range rather than the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry meets your supply. The rod retracts when energized, but you can reconfigure it to extend by repositioning the valve. Because the 800 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side-load wear. The valve routes air and does not lock the load; add an external rod lock or pilot-operated check valve for holding.
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 SAUF80X800-08A FAQ
It generates 2513 N push and 2268 N pull at 0.5 MPa, reaching 4021 N push at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25 mm2 flow) with a 4 cycles/sec max frequency. The AC220V terminal-entry coil is IP65 rated. You must size force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
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 will drift and the 28 mm cushion only decelerates near stroke end. For vertical load holding, install an external rod lock or a pilot-operated check valve.
