Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X80-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X80-06A 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 SAUF40X80-06A
The SAUF40X80-06A 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. It has a 1/4" cylinder port and an M12x1.25 rod thread.
Operating strictly within the valve's 0.15-0.8 MPa window, this 40mm bore delivers 628N push and 528N pull at 0.5 MPa. The integrated valve features a 1/8" port, Cv 0.78 flow, and 5 cycles/s. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 377N, allowing a 32kg vertical lift with a 2:1 margin. This SKU lacks a magnet and cannot accept sensors.

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 SAUF40X80-06A Is Used
Decentralized Clamping
Ideal for clamping stations where running a single AC220V signal to the cap valve is faster than piping back to a central manifold.
Inline Diverter Gate
A self-switching actuator that saves manifold slots and tubing on long conveyor lines with limited cabinet space.
Independent Tooling Stations
Perfect for modular machine beds where each 40mm bore tooling station must cycle independently at up to 5 cycles/s.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X80-06A the Right Choice?
Size by comparing neighbours: the 32mm bore yields 402N push while the 50mm bore yields 982N at 0.5 MPa. This 40mm unit provides 628N push, with a safe working load around 377N. Confirm the AC220V terminal entry and PT threads suit your supply. The rod retracts when energised but can be reconfigured 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 valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For this 80mm stroke side-load is minimal, but strokes over 300mm require 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 SAUF40X80-06A 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) with an AC220V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The valve only routes air; it is not a load lock. If air is lost the piston drifts, so add an external rod lock or pilot-operated check valve for holding.
