Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X160S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X160S-08A 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-08A
The SAUF80X160S-08A 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 makes it shorter than an ISO 15552 cylinder of the same bore. The 80mm bore uses a 3/8" cylinder port and an M20x1.5 rod thread.
It includes a piston magnet for CMSG/DMSG/EMSG switches. The integrated valve has a 1/4" port, Cv 1.4 flow, and cycles up to 4 times per second. The cylinder body rates to 1.0 MPa, but the assembled unit operates strictly within the 0.15-0.8 MPa valve window. At 0.5 MPa it pushes 2513 N, giving a safe working load of about 1508 N and a vertical lift capacity of roughly 128 kg 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 SAUF80X160S-08A Is Used
Sorting Diverter
Mounts directly on a conveyor diverter arm. The integrated valve handles rapid local switching without running long tubing back to a central manifold.
Pallet Stop Gate
Controls a heavy pallet stop gate. The 80mm bore provides high push force, while the AC220V terminal connection integrates easily with existing factory wiring.
Press Ejection
Ejects parts from a stamping press. The 4M310 valve supports up to 4 cycles per second, and the magnetic piston allows position confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X160S-08A the Right Choice?
Size by force: this 80mm bore pushes 2513 N at 0.5 MPa; step down to a 63mm bore for 1559 N, or up to a 100mm bore for 3927 N. The AC220V terminal entry coil runs at 3.5 VA with IP65 protection. By default the rod retracts when energised; repositioning the valve changes it to extend-when-energised. Because the built-in valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. For this 160mm stroke, guide the mechanism to manage side loads. Keep operating pressure between 0.15-0.8 MPa.
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-08A FAQ
It generates 2513 N push and 2268 N pull at 0.5 MPa, reaching 4021 N at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4) driven by an AC220V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
No. The built-in 5/2 valve routes air but does not lock the piston. If air is lost, the rod drifts and the 28mm adjustable cushions only decelerate near stroke end. Install an external rod lock or pilot-operated check valve for secure load holding.
