Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X500-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X500-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 500mm 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 SAUF40X500-06A
The SAUF40X500-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 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. This 40mm bore uses a 1/4" cylinder port, a Ø16mm rod with an M12x1.25 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 1/8" valve port yields a 14 mm2 flow (Cv 0.78) with a 5 cycle/s limit. The AC220V terminal coil is IP65 rated. For sizing, the safe working load is roughly 377N (about 60% of the 0.5 MPa push), allowing a 32kg vertical lift with a 2:1 margin. This SKU lacks a magnet and cannot accept a sensor.

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 SAUF40X500-06A Is Used
Sorting Diverter
Decentralized diverter gate on a conveyor. One AC220V signal flips the 500mm stroke gate without running long tubing back to a central manifold.
Pallet Push-Off
Pushes pallets off an accumulation line. The 4M210-06 valve handles the 5 cycle/s demand locally, saving manifold space.
Long-Stroke Ejector
Ejects machined parts from a cell. The 40mm bore provides 628N push at 0.5MPa, with an external guide handling the 500mm side-load.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X500-06A the Right Choice?
Size by checking both neighbours: the 32mm bore offers 402N push at 0.5MPa, while the 50mm bore provides 982N. This 40mm bore gives 628N push and 528N pull at 0.5MPa. Confirm the AC220V terminal entry and PT threads suit your control panel. The default action retracts the rod when energised; reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because this is a 500mm stroke, use an external guide to prevent rod bending and side-load wear. The built-in valve routes air but does not lock the load; add an external rod lock or pilot-operated check valve for hold. Without a magnet, this SKU cannot take a sensor.
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 SAUF40X500-06A FAQ
It pushes 628N and pulls 528N at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s max). The AC220V terminal coil is IP65. Although the cylinder body rates to 1.0MPa, the assembled unit must operate in the 0.15-0.8MPa valve window.
No remote valve is needed; the integrated 5/2 valve switches the actuator directly. However, the valve only routes air and is not a lock. The rod will drift on air loss, so you must add an external rod lock or pilot-operated check valve to hold a load.
