Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X800S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X800S-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 800mm 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 SAUF40X800S-06A
The SAUF40X800S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. It features a 1/4" cylinder port, an M12x1.25 rod thread, and a piston magnet for CMSG/DMSG/EMSG switches.
The integrated valve restricts the assembled working pressure to a 0.15-0.8 MPa window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa this 40mm bore delivers 628N push and 528N pull force. The 1/8" valve port yields a 14 mm2 flow (Cv 0.78) with a 5 cycle/s limit. For sizing, the safe working load is roughly 377N, and vertical lift capacity is about 32kg 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 SAUF40X800S-06A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert station. One AC220V signal actuates the 800mm stroke without tubing back to a central manifold.
Long-Reach Pusher Arm
Ideal for pushing pallets on a roller bed. The 4M210-06 valve handles the cycling locally, saving manifold space.
Magnet-Equipped Part Gate
The internal piston magnet works with CMSG sensors to confirm the 800mm extended position before the next machine cycle begins.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X800S-06A the Right Choice?
Size this 40mm bore against the neighbouring 32mm (402N push) and 50mm (982N push) options at 0.5 MPa. Confirm the AC220V terminal entry and PT thread meet your control spec. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For the 800mm stroke, use an external guide to prevent rod bending and side-load 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 SAUF40X800S-06A FAQ
It delivers 628N push and 528N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s max) running on an AC220V terminal-entry coil. The cylinder body rates to 1.0 MPa, but the assembled unit must operate within the 0.15-0.8 MPa valve window.
Yes. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. The valve only routes air; it is not a load lock. The piston will drift on air loss, so fit an external rod lock or pilot-operated check valve for load holding.
