Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 700mm 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 SAUF40X700-06A
The SAUF40X700-06A 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 cylinder of the same bore. This 40mm bore uses a 1/4" cylinder port and a 1/8" valve port with a 14 mm2 flow (Cv 0.78), supporting up to 5 cycles per second.
Operating within the 0.15-0.8 MPa valve window, it delivers 628 N push force at 0.5 MPa. A practical computed insight sets the safe working load near 377 N, allowing a vertical lift of roughly 32 kg with a 2:1 margin. This terminal-entry, PT-thread SKU lacks a magnet (-S), so it cannot accept a magnetic switch.

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 SAUF40X700-06A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert station to push packages, needing only one coil signal and no long tubing runs back to a central manifold.
Independent Machine Clamp
Ideal for a standalone clamping operation on a large machine, saving manifold space while delivering 628 N push force at 0.5 MPa.
Vertical Gate Actuator
Lifts a 32kg vertical gate with a 2:1 safety margin, operating independently with its built-in 4M210 valve for localized control.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700-06A the Right Choice?
When sizing, compare neighbouring bores: a 32mm bore yields 402 N push at 0.5 MPa, while a 50mm bore provides 982 N. This 40mm bore generates 628 N push and 528 N pull at 0.5 MPa. Confirm the AC220V terminal entry matches 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. Because air only routes through the valve, add an external rod lock or pilot-operated check valve to hold loads. For this 700mm stroke, use external guides to prevent rod bending and side loads.
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 SAUF40X700-06A 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/s max) running on an AC220V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, you must size force within the assembled valve's 0.15-0.8 MPa operating window.
By default the rod retracts when the coil is energised, but you can reconfigure it to extend by repositioning the valve. The 5/2 valve only routes air; it is not a load lock. On air loss the piston drifts, so add an external rod lock or pilot-operated check valve for load holding.
