Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175S-06B 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 SAUF40X175S-06B
The SAUF40X175S-06B is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve mounted directly on the cap. This decentralized design means one DC24V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. It is significantly shorter than an ISO 15552 cylinder of the same bore.
Operating within the valve's 0.15-0.8 MPa window, this 40mm bore generates 628N push and 528N pull at 0.5 MPa. The integrated valve flows 14 mm2 (Cv 0.78) at up to 5 cycles/sec. For sizing, the safe working load is roughly 377N, and it can vertically lift about 32kg with a 2:1 margin. The bore features a 1/4" cylinder port, M12x1.25 rod thread, and uses Ø8xØ5 PU tubing. The S suffix denotes a piston magnet for CMSG/DMSG/EMSG switches.

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 SAUF40X175S-06B Is Used
Decentralized Conveyor Diverter
Installs directly along a conveyor line to push packages, switching itself with one DC24V signal without routing air back to a central manifold.
Independent Clamping Station
Provides single-actuator clamping on a machining cell, saving manifold space and simplifying tubing by mounting the 4M210-06 valve onboard.
Compact Sorter Gate
Fits into tight warehouse sorting frames where a shorter profile cylinder is required, using the built-in magnet for position feedback.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175S-06B the Right Choice?
Size force within the 0.15-0.8 MPa valve range: this 40mm bore pushes 628N at 0.5 MPa, sitting between the 50mm (982N) and 32mm (402N) bores. Confirm the DC24V terminal entry and PT thread meet your control specs. The rod retracts when the coil energises, but you can reposition the valve to extend on signal. Because the valve only routes air, add an external rod lock or pilot-operated check valve if you need to hold a load against pressure loss. For this 175mm 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 SAUF40X175S-06B FAQ
It pushes 628N and pulls 528N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) driven by a DC24V terminal coil. Although the cylinder body rates to 1.0 MPa, size force within the assembled valve's 0.15-0.8 MPa operating window.
No, the built-in valve routes air and is not a lock. If air is lost, the piston drifts. For load holding, install an external rod lock or pilot-operated check valve. You can also reposition the valve to switch the default action from retract-when-energised to extend-when-energised.
