Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X175-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X175-08A 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 SAUF80X175-08A
The SAUF80X175-08A 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 pushes 2513N at 0.5MPa and reaches 4021N at 0.8MPa. The cylinder port is 3/8" and the valve port is 1/4".
The integrated valve flows 25mm2 (Cv 1.4) with a max 4 cycles/sec. It runs on AC220V terminal entry with an IP65 class B coil. 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 roughly 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 SAUF80X175-08A Is Used
Package Diverter Gate
Uses the integrated 4M310-08 valve to flip a routing flap on a conveyor line without running air lines back to a central manifold.
Decentralized Pallet Stop
Deploys a heavy stop block on a roller conveyor; the built-in valve handles the 80mm bore force locally for fast response.
Machine Tool Clamp
Clamps a casting in a machining cell. One AC220V signal actuates the clamp directly at the fixture, saving manifold space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X175-08A the Right Choice?
Size by checking both neighbor bores: the 63mm bore yields 1559N push at 0.5MPa, while the 100mm bore yields 3927N. This 80mm bore gives 2513N push and 2268N pull at 0.5MPa. Confirm the AC220V terminal entry and PT thread meet your electrical specs. The rod retracts when the coil energises; reposition the valve to switch to extend-when-energised. Limit operating pressure to 0.15-0.8MPa. The valve routes air but does not lock the load; add an external rod lock or pilot-operated check valve for holding. Since the 175mm stroke is under 300mm, side-load guides are less critical but still advised for rigid mounting.
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 SAUF80X175-08A FAQ
It pushes 2513N and pulls 2268N at 0.5MPa, reaching 4021N at 0.8MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 4 cycles/sec) running on AC220V. The cylinder body rates to 1.0MPa, but the assembled unit must operate in the 0.15-0.8MPa valve window.
No, the built-in valve only routes air and is not a load lock; the piston drifts on air loss, so add an external rod lock or pilot-operated check valve for holding. Also, this specific SKU lacks a magnet and cannot take a magnetic sensor.
