Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 175mm stroke and a built-in 4M210-06 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 SAUF40X175-06A
The SAUF40X175-06A is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The design is more compact than an ISO 15552 unit of the same bore. This 40mm bore uses a 1/4" cylinder port, a Ø16mm rod with an M12x1.25 thread, and 21mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa range, it delivers 628N push and 528N pull at 0.5 MPa. The 4M210-06 valve features a 1/8" port, 14 mm2 flow (Cv 0.78), and handles up to 5 cycles per second. The AC220V terminal-entry coil is IP65 rated. For sizing, the safe working load is roughly 377N (about 60% of the 0.5 MPa push force), and it can vertically lift around 32kg with a 2:1 safety 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAUF40X175-06A Is Used
Decentralized Conveyor Diverter
Installs directly on a conveyor line to push packages. The integrated 4M210 valve eliminates long tube runs back to a central manifold, saving install time.
Independent Clamping Station
Ideal for a standalone clamping fixture on a large machine. One AC220V signal actuates the clamp without occupying a slot on the main valve island.
Compact Assembly Ejector
Ejects parts from an assembly cell. The extruded profile body fits tight spaces, and the built-in 5/2 valve ensures rapid local switching up to 5 cycles per second.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175-06A the Right Choice?
Size by comparing neighbouring bores: the 32mm bore offers 402N push at 0.5 MPa, while the 50mm bore provides 982N. This 40mm bore gives 628N push and 528N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve operating window, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry meets your control voltage. By default the rod retracts when the coil is energised; repositioning the valve changes it to extend-when-energised. Since this SKU lacks a magnet (-S), it cannot accept a magnetic switch. The built-in valve routes air but does not lock the piston; add an external rod lock or pilot-operated check valve to hold loads securely. For this 175mm stroke, ensure standard 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 SAUF40X175-06A FAQ
It delivers 628N push and 528N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s max). The AC220V terminal-entry coil is IP65 rated. Although the cylinder body rates to 1.0 MPa, you must size force within the valve's 0.15-0.8 MPa operating window.
The built-in valve routes air but is not a load lock; the piston drifts on air loss. Add an external rod lock or pilot-operated check valve for holding. By default the rod retracts when energised, but you can reposition the valve to extend-when-energised. This SKU has no magnet and cannot take a sensor.
