Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X80S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X80S-08A is a genuine double-acting profile-type cylinder with a Ø80mm 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 SAUF80X80S-08A
The AirTAC SAUF80X80S-08A is a double-acting profile cylinder with a built-in 4M310 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 makes it shorter than an ISO 15552 unit of the same bore. It features an 80mm bore, an 80mm stroke, a 3/8" cylinder port, and a 1/4" valve port.
Operating strictly within the 0.15-0.8 MPa valve window, it generates 2513 N push force at 0.5 MPa. The integrated valve provides 25 mm2 flow (Cv 1.4) and handles up to 4 cycles per second. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 1508 N, and it can vertically lift about 128 kg with a 2:1 margin. The S suffix denotes 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 SAUF80X80S-08A Is Used
Package Diverting Gate
Drives a decentralized diverting arm directly on the conveyor frame. One coil signal actuates the gate without routing long tubing back to a central manifold.
Vertical Material Lift
Lifts 128kg loads in a storage buffer using the 2513N push force. The built-in 4M310 valve handles up to 4 cycles per second for rapid throughput.
Machine Tool Clamping
Clamps heavy castings at a machining station. The compact profile barrel saves space, while the S suffix magnet enables position confirmation via CMSG switches.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X80S-08A the Right Choice?
Size this 80mm bore against the neighbouring 63mm and 100mm options. At 0.5 MPa it yields 2513 N push and 2268 N pull force, while the 63mm bore offers 1559 N and the 100mm provides 3927 N. Confirm the AC220V terminal entry power supply matches your control circuit. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. For strokes of 300mm or longer, use side-load guides to prevent rod 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 SAUF80X80S-08A FAQ
It generates 2513 N push and 2268 N pull force at 0.5 MPa, reaching 4021 N push at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25 mm2 flow) with an AC220V terminal entry coil. You must size the force within the 0.15-0.8 MPa operating window of the valve, even though the cylinder body rates to 1.0 MPa.
Yes. The default factory setting retracts the rod when the coil receives power. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This self-switching design removes the need for a separate remote valve, saving installation time and manifold space.
