Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800S-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 SAUF80X800S-08A
The SAUF80X800S-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 is shorter than an ISO 15552 unit of the same bore. This 80mm bore version has a 3/8" cylinder port, a 1/4" valve port, and a piston magnet for switches.
Size force within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it pushes 2513 N and pulls 2268 N. For sizing, the safe working load is roughly 1508 N (60% of the 0.5 MPa push force), translating to a vertical lift capacity of about 128 kg with a 2:1 margin. The AC220V terminal-entry coil offers IP65 protection, and the valve flows 25 mm2 (Cv 1.4) at up to 4 cycles per second.

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 SAUF80X800S-08A Is Used
Sorting Diverter
Drives a decentralized diverter gate on a high-speed conveyor using its built-in valve, eliminating long tubing runs back to a central manifold.
Vertical Lift Gate
Lifts a 128 kg access gate in a warehouse using its 2513 N push force at 0.5 MPa, relying on the compact profile to save floor space.
Machine Guard Door
Actuates a heavy machine guard door with a single AC220V signal, using the 4M310-08 valve to cycle up to 4 times per second.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800S-08A the Right Choice?
When sizing, compare neighboring bores: the 63mm bore pushes 1559 N while the 100mm bore pushes 3927 N at 0.5 MPa. This 80mm bore provides 2513 N push force. Confirm your coil details: this unit uses AC220V with terminal entry. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Always operate within the 0.15-0.8 MPa valve pressure range. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For the 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 SAUF80X800S-08A FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4) operating on AC220V. You must size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating.
By default the rod retracts when the coil is energized. You can reconfigure it to extend-when-energized simply by repositioning the built-in valve. This self-switching design means no remote valve is needed.
