Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300S-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300S-10A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 300mm stroke and a built-in 4M310-10 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 SAUF80X300S-10A
The SAUF80X300S-10A is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M310-10 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The cylinder body rates to 1.0 MPa, but you must size force within the integrated valve's 0.15-0.8 MPa operating window.
At 0.5 MPa it delivers 2513 N push and 2268 N pull. This yields a safe working load of roughly 1508 N, or a 128 kg vertical lift with a 2:1 margin. The 3/8" valve port gives 30 mm2 flow (Cv 1.68) at up to 4 cycles/s. The bore's 3/8" cylinder port, M20x1.5 rod thread, and 28 mm cushions are fixed. The S suffix adds a piston magnet for CMSG/DMSG/EMSG switches.

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 SAUF80X300S-10A Is Used
Package Diverter
Decentralized diverter gate on a high-speed conveyor. One coil signal actuates the 300 mm stroke directly at the station without a remote valve manifold.
Pallet Stopper Gate
Independent pallet stop on a packaging line. The built-in 4M310-10 valve handles the 80 mm bore force locally, saving tubing runs across the machine frame.
Press Ejector
Ejecting formed parts from a press bed. The AC220V coil switches the 5/2 valve rapidly, routing 3/8" air to push parts clear using the magnetic piston for position feedback.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300S-10A the Right Choice?
Size by force: this 80 mm bore gives 2513 N push at 0.5 MPa; step down to a 63 mm bore for 1559 N, or up to a 100 mm bore for 3927 N. Confirm the AC220V terminal entry and PT threads. The rod retracts when energised but you can reconfigure it to extend by repositioning the valve. The integrated valve routes air but is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For the 300 mm 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 SAUF80X300S-10A FAQ
It uses a built-in 4M310-10 valve (3/8" port, Cv 1.68, 4 cycles/s) driven by an AC220V terminal-entry coil. The cylinder body rates to 1.0 MPa, but the assembled unit operates at 0.15-0.8 MPa. It pushes 2513 N and pulls 2268 N at 0.5 MPa, reaching 4021 N push at 0.8 MPa.
No. The built-in 5/2 valve only routes air; it is not a load lock. If air is lost, the piston drifts and the 28 mm cushions only decelerate near stroke end. Install an external rod lock or pilot-operated check valve for load holding.
