Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X160S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X160S-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 SAUF80X160S-08B
The SAUF80X160S-08B 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. This 80mm bore version includes a piston magnet for position sensing and delivers 2513N push force at 0.5MPa.
The integrated valve provides 25mm2 flow (Cv 1.4) at a 1/4" port, cycling up to 4 times per second. The cylinder body rates to 1.0MPa, but you must size force within the valve's 0.15-0.8MPa operating window. For practical sizing, the safe working load is roughly 1508N, and it can vertically lift about 128kg with a 2:1 margin. The bore dictates a 3/8" cylinder port and uses PU tube Ø10xØ6.5.

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 SAUF80X160S-08B Is Used
Machine Clamping Stations
Decentralized clamping on a large machining line where the built-in valve provides immediate local control without routing long tubing back to a central manifold.
Divertor Actuation
Driving heavy conveyor diverters directly at the actuator, saving manifold space and simplifying installation across wide material handling systems.
Pallet Stop Gates
Independent pallet stop gates in high-throughput logistics, where the integrated 4M310 valve ensures rapid local switching without complex air logic.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X160S-08B the Right Choice?
When sizing, compare this 80mm bore (2513N push at 0.5MPa) against the 63mm bore (1559N) or the 100mm bore (3927N) to match your load. The DC24V coil uses terminal entry with PT threads. By default the rod retracts when energised, but you can reconfigure it to extend by repositioning the valve. Always operate within the 0.15-0.8MPa valve limit. The valve only routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 160mm stroke, ensure adequate side-load guidance.
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 SAUF80X160S-08B FAQ
It delivers 2513N push and 2268N pull at 0.5MPa, reaching 4021N push at 0.8MPa. The built-in valve is a 4M310-08 (Cv 1.4, 25mm2 flow) with a 1/4" port and a DC24V terminal-entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa range. The bore features a 3/8" cylinder port.
By default, the rod retracts when the coil is energised. You can reconfigure it to extend when energised simply by repositioning the built-in valve. Because the valve routes air rather than locking it, you must add an external rod lock or pilot-operated check valve if you need to hold a load securely during air loss.
