Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150S-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 150mm 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 SAUF40X150S-06B
The AirTAC SAUF40X150S-06B is a double-acting profile cylinder with a built-in 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
It delivers 628 N push and 528 N pull at 0.5 MPa. A safe working load is about 377 N, allowing a 32 kg vertical lift with a 2:1 margin. The integrated 4M210-06 valve has a 1/8" port, 14 mm2 flow (Cv 0.78), and handles 5 cycles/s. The cylinder body rates to 1.0 MPa, but size force within the valve's 0.15-0.8 MPa window. The bore's air port is 1/4".

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 SAUF40X150S-06B Is Used
Diverter Gate Control
Decentralized diverter actuation on a conveyor line. The integrated valve means one DC24V signal per gate, removing the need to route long tubing runs back to a central manifold.
Independent Clamping Station
A standalone clamping fixture on a large machine bed. The built-in 4M210 valve provides immediate local response without consuming a slot in the main valve island.
Modular Assembly Jig
A self-contained assembly station actuator. The profile cylinder with its onboard solenoid simplifies installation, requiring only a power signal and a 1/4" main air supply.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150S-06B the Right Choice?
Size by checking both neighboring bores: the 32 mm bore pushes 402 N at 0.5 MPa, while the 50 mm bore pushes 982 N. This 40 mm bore provides 628 N push at 0.5 MPa. Confirm the DC24V terminal entry and PT thread match your control system. The rod retracts when the coil is energized, but you can reposition the valve to extend on energization. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 150 mm stroke, ensure side-load guidance to prevent rod wear.
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 SAUF40X150S-06B FAQ
It delivers 628 N push and 528 N pull at 0.5 MPa, reaching 1005 N push at 0.8 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s) running on DC24V. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
By default, the rod retracts when the coil is energized. You can reconfigure it to extend on energization by physically repositioning the built-in valve on the cylinder cap. This self-switching design means no remote valve is needed.
