Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X80-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X80-06B 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 SAUF40X80-06B
The SAUF40X80-06B 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 cylinder of the same bore. It has a 1/4" cylinder port, an M12x1.25 rod thread, and 21mm adjustable cushions.
Operating in the 0.15-0.8 MPa valve window, it delivers 628N push and 528N pull at 0.5 MPa. The integrated 4M210-06 valve has a 1/8" port, 14mm2 flow (Cv 0.78), and handles 5 cycles/sec. The DC24V terminal coil is IP65 rated. For sizing, a safe working load is roughly 377N (60% of the 0.5MPa push), offering a 32kg vertical lift capacity 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 SAUF40X80-06B Is Used
Decentralized Clamping
Ideal for independent clamping stations on a large fixture, switching directly from one DC24V signal without routing tubing back to a central manifold.
Inline Divert Gates
Drives small sorting gates on a conveyor line, using the compact profile and built-in 4M210 valve to maximize space and simplify maintenance.
Component Ejection
Ejects machined parts directly at the tool. The 5 cycles/sec valve speed and 628N force handle rapid, localized ejection tasks efficiently.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X80-06B the Right Choice?
Size between the 32mm bore (402N push @0.5MPa) and 63mm bore (1559N push @0.5MPa) based on your load. This 40mm bore gives 628N push at 0.5MPa. Confirm the DC24V terminal entry and PT threads suit your control system. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Size force strictly within the 0.15-0.8 MPa valve range, not the 1.0MPa cylinder body rating. Because this SKU lacks the -S magnet suffix, it cannot accept a magnetic switch. The 5/2 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 80mm stroke side-load is minimal, but if you exceed 300mm, guide the load to prevent rod bending.
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 SAUF40X80-06B FAQ
It delivers 628N push and 528N pull at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) driven by a DC24V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate in the 0.15-0.8MPa valve window.
By default the rod retracts when the coil is energized, but you can reposition the valve to extend on signal. The 5/2 valve only routes air; it is not a load lock. If you need to hold a load during air loss, install an external rod lock or pilot-operated check valve.
