Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175S-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 SAUF40X175S-06A
The SAUF40X175S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210 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 cylinder of the same bore. This unit includes a piston magnet for CMSG/DMSG/EMSG switches.
Operating within the 0.15-0.8 MPa valve window, this 40 mm bore delivers 628 N push at 0.5 MPa. The integrated valve features a 1/8" port with 14 mm2 flow (Cv 0.78) and handles 5 cycles per second. The cylinder uses a 1/4" air port with an M12x1.25 rod thread. For sizing, the safe working load is roughly 377 N, and it can vertically lift about 32 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 (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-06A Is Used
Diverter Gate Actuation
Decentralized conveyor sorting where the built-in valve mounts directly at the diverter, cutting tubing runs to a central manifold.
Compact Clamping Station
Independent machining clamps driven by one AC220V signal per actuator, saving manifold space while providing 628 N of clamping force.
Component Pusher
Assembly line pushers requiring 5 cycles per second, utilizing the integrated 4M210 valve for fast, local switching without remote plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175S-06A the Right Choice?
When sizing, compare neighbouring bores: a 32 mm bore offers 402 N push while a 50 mm bore provides 982 N at 0.5 MPa. This 40 mm bore yields 628 N push and 528 N pull at 0.5 MPa. Confirm the AC220V terminal entry and PT thread meet your electrical specs. Size force strictly within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The rod retracts when the coil is energised; reposition the valve to reverse this to extend-when-energised. The valve routes air and does not hold the load on pressure loss, so add an external rod lock or pilot-operated check valve for suspended loads. For this 175 mm 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-06A FAQ
It delivers 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-06 with a 1/8" port, Cv 0.78, and runs on AC220V. Although the cylinder body rates to 1.0 MPa, size force within the 0.15-0.8 MPa valve operating window.
No, the built-in valve only routes air and is not a load lock. The rod retracts when the coil is energised, which you can reconfigure to extend by repositioning the valve. For suspended loads, install an external rod lock or pilot-operated check valve.
