Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X900-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X900-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 900mm 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 SAUF40X900-06A
The SAUF40X900-06A 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 makes it shorter than an ISO 15552 unit of the same bore. This SKU uses terminal entry, PT threads, and a Ø16 mm rod with an M12x1.25 end thread. The bore sets the cylinder air port to 1/4".
Operating within the 0.15-0.8 MPa valve window, it delivers 628 N push and 528 N pull at 0.5 MPa. The integrated valve flows 14 mm2 (Cv 0.78) via a 1/8" port, switching up to 5 cycles/sec. The AC220V coil is IP65 rated with a 0.05 s response. For sizing, the safe working load is roughly 377 N (about 60% of the 0.5 MPa push force), translating to a vertical lift capacity of approximately 32 kg with a 2:1 margin. PU tubing is Ø8xØ5.

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 SAUF40X900-06A Is Used
Decentralized Forming Press
Drives a small press directly from the cylinder cap valve, eliminating long tubing runs back to a central manifold for faster cycle response.
Sorting Diverter Gate
Uses the one-signal switching to actuate a 900 mm diverter arm, saving manifold space while handling parts along the line.
Vertical Lift Station
Lifts light loads up to 32 kg using the built-in valve, simplifying installation in distributed warehouse automation cells.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X900-06A the Right Choice?
Size force between the 32 mm bore (402 N push @0.5 MPa) and the 50 mm bore (982 N push @0.5 MPa) depending on your load. This 40 mm bore provides 628 N push at 0.5 MPa, operating strictly within the 0.15-0.8 MPa valve limit rather than the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry matches your supply. The default action retracts the rod when energised; you can reconfigure it to extend-when-energised by repositioning the valve. Because this SKU lacks a magnet (-S), it cannot accept a magnetic switch. The 900 mm stroke requires an external guide to prevent rod bending and side loads. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve for load holding.
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 SAUF40X900-06A FAQ
It delivers 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) with an AC220V terminal-entry coil. You must size force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
The valve routes air and is not a load lock, so the piston drifts on air loss—add an external rod lock or pilot-operated check valve to hold a load. By default the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This one-signal design removes the need for a remote valve.
