Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X160-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X160-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 160mm 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 SAUF80X160-08B
The SAUF80X160-08B is a double-acting profile cylinder with a built-in AirTAC 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 is shorter than an ISO 15552 cylinder of the same bore. This 80mm bore pushes 2513N and pulls 2268N at 0.5MPa, with a 3/8" cylinder port and an M20x1.5 rod thread.
The integrated 4M310-08 valve has a 1/4" port, Cv 1.4 flow, and cycles up to 4 times per second. The DC24V coil offers IP65 protection with a 0.05s response. The cylinder body rates to 1.0MPa, but the valve limits operation to 0.15-0.8MPa. Based on the 0.5MPa push force, the safe working load is 1508N, and it can vertically lift about 128kg with a 2:1 margin.

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 SAUF80X160-08B Is Used
Decentralized Diverters
Drives individual conveyor sorting gates directly from the actuator, removing the need for a central valve manifold and long tubing runs.
Independent Lift Stations
Powers standalone vertical lift stops in a high-bay warehouse, switching locally with one DC24V signal to save installation time.
Machine Clamping Units
Actuates remote clamping fixtures on a large machine bed, using the built-in 4M310 valve to avoid routing multiple air lines back to a main panel.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X160-08B the Right Choice?
Size by checking both neighboring bores: the 63mm bore yields 1559N push while the 100mm bore yields 3927N at 0.5MPa. This 80mm bore provides 2513N push at 0.5MPa, peaking at 4021N at the 0.8MPa valve maximum. Confirm the DC24V terminal entry and PT threads suit your control panel. The rod retracts when the coil energizes; reposition the valve to reverse this to extend-when-energised. The valve routes air and does not lock the load; add an external rod lock or pilot-operated check valve for holding. Since the 160mm stroke is under 300mm, side-load guides are less critical. This SKU lacks the -S magnet and cannot take a sensor.
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 SAUF80X160-08B FAQ
It generates 2513N push and 2268N pull at 0.5MPa, reaching 4021N at 0.8MPa. It uses a 4M310-08 valve with 1/4" port and Cv 1.4. The coil is DC24V with terminal entry. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within the 0.15-0.8MPa valve window.
Yes, the default action retracts the rod when energized, but you can reposition the valve to extend when energized. The 5/2 valve only routes air and is not a load lock; the piston will drift on air loss. Use an external rod lock or pilot-operated check valve to hold a load.
