Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 300mm 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 SAUF80X300-08A
The SAUF80X300-08A is an extruded aluminum profile-type double-acting 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. It is shorter than an ISO 15552 cylinder of the same bore and mounts with AirTAC SC-series accessories. The bore sets a 3/8" cylinder port and an M20x1.5 rod thread.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers 2513 N push force at 0.5 MPa. The 1/4" valve port gives 25 mm2 flow (Cv 1.4) at up to 4 cycles/s. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 1508 N, and vertical lift capacity is about 128 kg with a 2:1 margin. This SKU lacks a magnet, so it cannot accept 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 (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 SAUF80X300-08A Is Used
Sorting Diverter
Decentralized diverter gate on a high-speed conveyor. The integrated valve eliminates long tube runs back to a central manifold, ensuring rapid 4 cycles/s actuation.
Pallet Stopper
Independent pallet stop in a multi-zone warehouse. One AC220V signal controls the 300mm stroke directly at the station, saving manifold space and install time.
Machine Guard Gate
Remote access gate on a large machine. The self-contained 4M310-08 valve simplifies wiring and plumbing while providing 2513 N push force to move the heavy guard.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300-08A the Right Choice?
Size this 80mm bore against the neighbouring 63mm and 100mm options, checking the 2513 N push force at 0.5 MPa to ensure it fits your load. Confirm the AC220V terminal entry coil matches your supply. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The built-in valve only routes air and does not hold the load on pressure loss; add an external rod lock or pilot-operated check valve if needed. For this 300mm stroke, use external guides 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 SAUF80X300-08A 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, 4 cycles/s max) driven by an AC220V terminal coil. Although the cylinder body rates to 1.0 MPa, you must size force within the valve's 0.15-0.8 MPa operating window.
No, the built-in valve only routes air and is not a lock; the piston drifts on air loss and the 28mm cushions only decelerate near stroke end. Add an external rod lock or pilot-operated check valve for holding. By default the rod retracts when energised, but you can reposition the valve to extend on signal.
