Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 350mm 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 SAUF80X350-08A
The SAUF80X350-08A 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 SKU uses terminal entry with PT threads and has no magnet, so it cannot accept a magnetic switch.
Operating within the 0.15-0.8 MPa valve window, it delivers a 2513 N push force at 0.5 MPa. The 1/4" valve port provides 25 mm2 flow (Cv 1.4) at up to 4 cycles per second. The cylinder body rates to 1.0 MPa, but the assembled unit is capped by the valve's 0.8 MPa limit. Based on the 0.5 MPa push force, the safe working load is about 1508 N, and it can vertically lift 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 SAUF80X350-08A Is Used
Divert Gate Actuation
Drives a heavy lane diverter directly at the conveyor frame without routing long tubing back to a central manifold.
Pallet Stopper Assembly
Provides a hard stop for incoming pallets on a gravity roller line, switching itself locally to sync with the line speed.
Press Ejection Station
Ejects finished parts from a press bed using one coil signal, saving manifold space in a crowded machine layout.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350-08A the Right Choice?
Size this 80 mm bore against the neighboring 63 mm and 100 mm options. At 0.5 MPa it pushes 2513 N and pulls 2268 N. Verify the AC220V terminal entry matches your control signal. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. 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 this 350 mm stroke, use an external guide to prevent rod bending and side-load wear.
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 SAUF80X350-08A FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa. The built-in 4M310-08 valve has a 1/4" port, Cv 1.4, and runs on AC220V. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
No remote valve is needed; the integrated 4M 5/2 valve switches the cylinder from one coil signal. The valve only routes air, so it is not a load lock. The rod drifts on air loss, so add an external rod lock or pilot-operated check valve for load holding.
