Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X80-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X80-08A 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 SAUF80X80-08A
The SAUF80X80-80A 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. It features a 3/8" cylinder port, an M20x1.5 rod thread, and 28mm adjustable cushions.
Operating strictly within the valve's 0.15-0.8 MPa window, it generates 2513 N push and 2268 N pull at 0.5 MPa. A practical safe working load is roughly 1508 N, capable of a 128 kg vertical lift with a 2:1 margin. The 1/4" valve port yields a Cv of 1.4 and cycles up to 4 times per second. The AC220V terminal coil is IP65 rated. Note this SKU lacks a magnet and cannot accept a sensor.

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 SAUF80X80-08A Is Used
Decentralized Clamping
Ideal for large machining cells where routing a manifold to each clamp is impractical, switching directly via the AC220V terminal signal.
Inline Diverters
Perfect for distributed conveyor sorting gates that require independent 4M310 valve control without a central valve bank.
Package Stops
Provides robust localized stopping power on packaging lines, saving tubing by mounting the valve directly on the cylinder cap.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X80-08A the Right Choice?
Size by comparing neighbours: the 63mm bore yields 1559 N push at 0.5 MPa, while the 100mm bore reaches 3927 N. This 80mm unit provides 2513 N, making it ideal for mid-range loads. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry matches your supply. The rod retracts when energised by default; reposition the valve to extend on signal. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. For this 80mm stroke, side-load guides are optional but recommended for rigid mounting.
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 SAUF80X80-08A FAQ
It generates 2513 N push at 0.5 MPa. The built-in valve is a 4M310-08 with a 1/4" port and Cv of 1.4. The coil is AC220V. You must size the force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
By default, the rod retracts when the coil is energised. You can reposition the valve to make it extend when energised. The 5/2 valve only routes air; it is not a lock. The piston will drift on air loss, so add an external rod lock for load holding.
