Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X300S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X300S-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 300mm 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 SAUF40X300S-06B
The SAUF40X300S-06B is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One DC24V 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 cylinder air port to 1/4" and the rod thread to M12x1.25.
The integrated valve has a 1/8" port, 14 mm2 flow (Cv 0.78), and switches up to 5 cycles per second. Size force within the valve's 0.15-0.8 MPa working range, where the 40mm bore pushes 628 N at 0.5 MPa. This yields a safe working load of about 377 N, or a 32 kg vertical lift with a 2:1 margin. The piston magnet supports 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 SAUF40X300S-06B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping point needs independent control without routing tubes back to a central manifold.
Inline Divert Gate
Self-switching action provides rapid 5 cycle/s operation for a conveyor sorting gate without occupying a valve island slot.
Package Pusher
Perfect for a decentralized packaging line pusher, saving install time by driving the 300mm stroke directly from one coil signal.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X300S-06B the Right Choice?
Size between the 32mm and 50mm bores: this 40mm bore pushes 628 N at 0.5 MPa, sitting between the 32mm (402 N) and 50mm (982 N) options. Confirm the DC24V coil, terminal entry, and PT threads. The default action retracts the rod when energised; reposition the valve to extend on signal. The cylinder body rates to 1.0 MPa, but the assembled unit must operate in the 0.15-0.8 MPa valve window. 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 300mm 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 SAUF40X300S-06B FAQ
It uses a 4M210-06 valve (1/8" port, Cv 0.78, 5 cycles/s) on a 40mm bore. The cylinder port is 1/4". Force is 628 N push at 0.5 MPa. The coil is DC24V with terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly in the 0.15-0.8 MPa valve window.
Yes. The default action retracts the rod when the coil is energised. You can reconfigure it to extend on signal by repositioning the built-in valve. This self-contained switching means no remote valve is needed, saving tubing and a manifold slot.
