Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X175S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X175S-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 175mm 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 SAUF80X175S-08A
The SAUF80X175S-08A is an extruded aluminum profile-type double-acting 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 80mm bore delivers 2513N push at 0.5MPa, and the integrated piston magnet supports CMSG/DMSG/EMSG switches.
The built-in valve has a 1/4" port, Cv 1.4 flow, and switches up to 4 cycles/sec. The cylinder body rates to 1.0MPa, but you must size force within the valve's 0.15-0.8MPa window. Based on the 0.5MPa push force, the safe working load is about 1508N, yielding a 128kg vertical lift capacity 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 SAUF80X175S-08A Is Used
Machine Tool Clamping
Decentralized clamping on a large machining center. The built-in valve provides rapid 4Hz actuation directly at the fixture without a remote manifold.
Package Diverting
Independent diverting arms along a conveyor. One coil signal per actuator saves tubing and simplifies installation across long production lines.
Pallet Positioning
Pushing pallets into test stations. The compact profile and integrated switching deliver high push force without occupying manifold space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X175S-08A the Right Choice?
When sizing, compare this 80mm bore (2513N push at 0.5MPa) against the 63mm bore (1559N) or 100mm bore (3927N). Confirm the AC220V terminal entry and PT thread. The coil retracts the rod by default; reposition the valve to extend-when-energised. Always operate within the 0.15-0.8MPa valve range. The 4M310 valve routes air but does not lock the piston, so add an external rod lock or pilot-operated check valve to hold loads. For this 175mm stroke, ensure external guidance to manage side loads.
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 SAUF80X175S-08A FAQ
It pushes 2513N and pulls 2268N at 0.5MPa. The built-in 4M310-08 valve has a 1/4" port, Cv 1.4, and runs on AC220V. The cylinder body rates to 1.0MPa, but the assembled unit operates strictly within a 0.15-0.8MPa window.
Yes. The default action retracts the rod when energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This self-switching design eliminates the need for a separate remote valve.
