Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160S-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 160mm 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 SAUF40X160S-06B
The SAUF40X160S-06B 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 in decentralized layouts. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. The bore sets the 1/4" cylinder port and M12x1.25 rod thread, while the valve port is 1/8".
Size force within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it delivers 628 N push and 528 N pull. The safe working load is roughly 377 N, allowing a vertical lift of about 32 kg with a 2:1 margin. The 4M210-06 valve flows 14 mm2 (Cv 0.78) at up to 5 cycles/s. This DC24V terminal-entry coil is IP65 rated. 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 SAUF40X160S-06B Is Used
Decentralized Clamping Station
Distributes clamping across a large fixture. Each actuator fires from one local DC24V signal, removing long tube runs back to a central manifold.
Inline Diverter Gate
Switches product lanes on a conveyor. The built-in 4M210 valve achieves 5 cycles/s, ideal for high-speed sorting without remote plumbing.
Independent Pick-and-Place
Serves as a standalone vertical lift in robotic cells. The profile barrel saves space while the S suffix piston magnet tracks position for part pickup.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160S-06B the Right Choice?
Compare both ways: a 32 mm bore gives 402 N push at 0.5 MPa, while a 50 mm bore yields 982 N. This 40 mm bore provides 628 N push, making it the right middle ground. Confirm the DC24V terminal entry and PT threads suit your control panel. The rod retracts when the coil energises, but you can reposition the valve to extend-when-energised. Always size within the 0.15-0.8 MPa valve operating range. 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 160 mm stroke, standard guidance handles side loads, but add external guides for strokes over 300 mm.
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 SAUF40X160S-06B FAQ
It generates 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 14 mm2 flow) running on a DC24V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, you must size force within the assembled valve's 0.15-0.8 MPa operating window.
By default the rod retracts when the coil energises. You can reconfigure it to extend-when-energised by physically repositioning the valve on the cap. The 5/2 valve only routes air; it does not lock the piston. Add an external rod lock or pilot-operated check valve if you need to hold a load during air loss.
