Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X80S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X80S-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 80mm 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 SAUF40X80S-06B
The SAUF40X80S-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 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.
Operating in the 0.15-0.8 MPa valve window, this 40mm bore delivers 628N push and 528N pull at 0.5 MPa. The cylinder port is 1/4 inch, while the valve port is 1/8 inch. The integrated valve flows 14 mm2 (Cv 0.78) at up to 5 cycles per second. Computed buyer insight: safe working load is roughly 377N, and vertical lift is about 32kg with a 2:1 margin. The DC24V coil uses 3.0W, features IP65 protection, and responds in 0.05s or less.

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 SAUF40X80S-06B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal, saving manifold space and tubing runs.
Inline Diverters
Fits directly on a conveyor diverter arm to push packages, eliminating the need for a remote valve island.
Compact Assembly Stations
Perfect for tight assembly machine footprints where the shorter profile barrel and integrated valve save build time.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X80S-06B the Right Choice?
Size by checking both neighboring bores and the 0.5 MPa force figures: this 40mm bore gives 628N push, sitting between the 32mm (402N) and 50mm (982N) options. Confirm the DC24V coil and terminal entry suit your control system. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The integrated valve routes air and is not a lock; the piston drifts on air loss, so add an external rod lock or pilot-operated check valve to hold a load. For this 80mm stroke side-load is minimal, but for strokes of 300mm or more add a guide.
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 SAUF40X80S-06B FAQ
It delivers 628N push and 528N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8 inch port, Cv 0.78, 5 cycles/s max) running on DC24V. Size the force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod when the coil is energized. You can reconfigure it to extend-when-energized simply by repositioning the valve on the cap. This self-switching design means no remote valve is needed.
