Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X400S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X400S-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 400mm 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 SAUF40X400S-06B
The SAUF40X400S-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. The extruded aluminum barrel is 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".
Operating within the 0.15-0.8 MPa valve window, it delivers 628 N push at 0.5 MPa. A computed buyer insight: safe working load is roughly 377 N, and vertical lift is about 32 kg with a 2:1 margin. The DC24V terminal coil offers IP65 protection and the valve flows 14 mm2 (Cv 0.78) at up to 5 cycles per second. The S suffix means a piston magnet is present 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 SAUF40X400S-06B Is Used
Decentralized Divert Gate
Drives a routing flap directly on the conveyor frame using one DC24V signal, skipping long tube runs back to a central manifold.
Independent Stack Pusher
Cycles a pusher at up to 5 Hz in a packing cell; the integrated 4M210 valve eliminates the need for a dedicated remote valve island.
Modular Clamp Station
Clamps parts in a machining cell. The built-in magnet allows CMSG sensors to confirm clamp position locally without external hardware.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X400S-06B the Right Choice?
Size force between the 32 mm bore (402 N push) and 50 mm bore (982 N push) at 0.5 MPa. This 40 mm bore provides 628 N push and 528 N pull. Confirm the DC24V terminal entry and PT threads suit your control panel. The rod retracts when the coil energises; reposition the valve to extend on signal. Size strictly within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. For this 400 mm stroke, use external guides to prevent rod bending and 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 SAUF40X400S-06B FAQ
It delivers 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, 5 cycles/sec max) with a DC24V terminal coil. The cylinder body rates to 1.0 MPa, but 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 reposition the valve to extend on signal. The 5/2 valve only routes air, so it is not a load lock. If you need to hold a load on air loss, install an external rod lock or pilot-operated check valve.
