Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X80S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X80S-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 80mm 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 SAUF100X80S-08A
The AirTAC SAUF100X80S-08A is a double-acting profile cylinder with a built-in 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 cylinder of the same bore. This 100mm bore version pushes 3927N and pulls 3681N at 0.5MPa. The piston rod is Ø25mm with an M20x1.5 thread, and the cylinder air port is 1/2". An integrated piston magnet supports CMSG/DMSG/EMSG switches.
Size force strictly within the 0.15-0.8MPa valve window, even though the cylinder body rates to 1.0MPa. At 0.5MPa, the safe working load is roughly 2356N, and it can vertically lift about 200kg with a 2:1 margin. The 1/4" valve port delivers a Cv of 1.4 and handles up to 4 cycles per second. The AC220V terminal entry coil is IP65 rated and responds in 0.05s or less.

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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAUF100X80S-08A Is Used
Decentralized Press Clamps
One coil signal per clamp station removes the need for a massive central valve manifold on large press lines.
Independent Diverters
Self-switching diverters on a conveyor save tubing runs back to a control panel, speeding up installation.
Vertical Lift Gates
Lifts up to 200kg with a 2:1 margin at 0.5MPa, ideal for decentralized access gate actuators on storage systems.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X80S-08A the Right Choice?
When sizing, compare this 100mm bore against the 80mm neighbour: the 80mm push is 2513N versus 3927N here at 0.5MPa. Confirm the AC220V terminal entry and PT thread match your supply. The default action retracts the rod when energised, but repositioning the valve switches it to extend-when-energised. Because the built-in valve routes air rather than locking it, add an external rod lock or pilot-operated check valve for held loads. At 80mm stroke, this actuator is above the 75mm SAUF minimum, but for any stroke over 300mm you should guide the load to prevent 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 SAUF100X80S-08A FAQ
It pushes 3927N and pulls 3681N at 0.5MPa. The built-in valve is a 4M310-08 with a 1/4" port and Cv of 1.4. The AC220V coil runs the actuator within a 0.15-0.8MPa pressure window, despite the cylinder body rating to 1.0MPa.
No, the built-in valve routes air and is not a lock. The rod retracts by default when energised, but can be reconfigured to extend. For load holding on air loss, install an external rod lock or pilot-operated check valve.
