Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X900S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X900S-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 SAUF40X900S-06A
The SAUF40X900S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One AC220V 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 features a 1/4" cylinder port, M12x1.25 rod thread, and a piston magnet for CMSG/DMSG/EMSG switches.
Operating strictly within the valve's 0.15-0.8 MPa window, it generates 628 N push and 528 N pull at 0.5 MPa. The 1/8" valve port yields a Cv of 0.78 and supports up to 5 cycles per second. For sizing, the safe working load is roughly 377 N (60% of the 0.5 MPa push force), translating to a vertical lift capacity of about 32 kg 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 SAUF40X900S-06A Is Used
Sorting Diverter
Decentralized package sorting where one coil signal per actuator removes the need for a central manifold and long tubing runs.
Long-Stroke Pusher
900 mm stroke ideal for transferring parts between machine zones, utilizing the self-contained valve to simplify maintenance.
Vertical Gate Actuator
Lifting access gates with a safe working load around 32 kg, relying on the built-in magnet for position feedback.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X900S-06A the Right Choice?
Size this 40 mm bore against the neighboring 32 mm and 50 mm options using the 0.5 MPa thrust figures (628 N push here). Verify the AC220V terminal entry and PT thread meet your control spec. 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, not 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 a load. Because the 900 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side-load damage.
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 SAUF40X900S-06A FAQ
It generates 628 N push and 528 N pull at 0.5 MPa, and up to 1005 N push at 0.8 MPa. The built-in valve is a 4M210-06 5/2 solenoid with a 1/8" port, Cv 0.78, and 5 cycles/sec max. The coil is AC220V with terminal entry. You must size force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
No, the built-in valve only routes air and is not a load lock. If air is lost or the valve is centered, the piston will drift. To maintain a vertical or suspended load, you must install an external rod lock or a pilot-operated check valve.
