Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350S-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 350mm 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 SAUF40X350S-06A
The SAUF40X350S-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. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
Operating in the 0.15-0.8 MPa valve window, this 40 mm bore delivers 628 N push and 528 N pull at 0.5 MPa. The computed safe working load is about 377 N, allowing a 32 kg vertical lift with a 2:1 margin. The integrated 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and handles 5 cycles/sec. The cylinder body rates to 1.0 MPa, but the assembled unit is limited by the valve to 0.8 MPa. The bore's air port is 1/4", with a 16 mm rod and M12x1.25 thread.

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 SAUF40X350S-06A Is Used
Conveyor Diverter Gate
Decentralized diverter on a packaging line. The built-in valve eliminates long tube runs back to a central manifold, ensuring fast 5 cycles/sec response.
Warehouse Sortation Pusher
One-signal actuation for a 350 mm sortation stroke. The integrated 4M210 valve saves manifold space while the piston magnet tracks position.
Component Ejection Station
Ejects parts from a machine cell. The AC220V coil switches directly at the actuator, reducing install time and tubing clutter.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350S-06A the Right Choice?
Size by comparing neighbor bores: a 32 mm bore gives 402 N push at 0.5 MPa, while a 50 mm bore yields 982 N. This 40 mm bore provides 628 N push. Confirm the AC220V terminal entry and PT threads suit your control panel. The rod retracts when the coil is energized, but you can reposition the valve to extend-when-energized. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For the 350 mm stroke, use external guides to prevent rod bending and side loads. Mounting uses AirTAC SC series accessories.
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 SAUF40X350S-06A FAQ
It delivers 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-06 with a 1/8" port and Cv 0.78. The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly in the 0.15-0.8 MPa valve window.
By default the rod retracts when the coil is energized. You can reconfigure it to extend-when-energized simply by repositioning the built-in valve. This self-switching design means no remote valve is needed, saving a manifold slot and tubing.
