Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X80S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X80S-08B 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-08B
The AirTAC SAUF80X80S-08B 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 valves and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG sensors.
Operating in the 0.15-0.8 MPa valve window, it delivers 2513 N push force at 0.5 MPa. The 1/4" port valve flows 25 mm2 (Cv 1.4) at up to 4 cycles/s. The bore sets a 3/8" cylinder port, M20x1.5 rod thread, and 28 mm cushions. For sizing, expect a safe working load around 1508 N or a 128 kg vertical lift with a 2:1 margin. The DC24V terminal coil offers IP65 protection.

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-08B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert station. The integrated DC24V valve switches the 80 mm stroke locally, removing long tubing runs back to a central manifold.
Machine Tool Clamp
Provides 2513 N push force at 0.5 MPa for secure workholding. The built-in 4M310-08 valve frees up manifold space while the magnetic piston tracks clamp position.
Packaging Gate Actuator
Drives a sorting gate at up to 4 cycles/s. The compact profile barrel fits tight machine frames, and the 1/4" valve port handles the 25 mm2 flow requirement.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X80S-08B the Right Choice?
Size against neighbours: bore 63 gives 1559 N push at 0.5 MPa, while bore 100 gives 3927 N. This 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Confirm the DC24V terminal coil and PT thread suit your control system. Default action retracts the rod when energised; reposition the valve to extend on signal. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold loads. The 80 mm stroke is above the 75 mm minimum. For strokes 300 mm or longer, use SC-series mounts and 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 SAUF80X80S-08B FAQ
It generates 2513 N push and 2268 N pull at 0.5 MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port, Cv 1.4, and runs on DC24V. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
By default, the rod retracts when the coil is energised. You can reposition the valve to extend on signal. The valve only routes air; it does not lock the piston. If air drops, the load drifts. Use an external rod lock or pilot-operated check valve for holding.
