Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700-06B 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 SAUF40X700-06B
The SAUF40X700-06B 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 makes it shorter than an ISO 15552 unit of the same bore.
It delivers 628 N push and 528 N pull at 0.5 MPa. The integrated valve operates at 0.15-0.8 MPa with a 1/8" port and Cv 0.78, running up to 5 cycles/s. The cylinder body rates to 1.0 MPa, but size force within the 0.15-0.8 MPa valve window. Computed insight: safe working load is ~377 N (60% of the 628 N push), allowing a ~32 kg vertical lift with a 2:1 margin. The 1/4" cylinder port, M12x1.25 rod thread, and 21 mm cushions are fixed by this 40 mm bore.

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 SAUF40X700-06B Is Used
Inline Diverter Gate
Switches sorting flaps directly on the conveyor frame using one DC24V signal, avoiding long tube runs back to a central manifold.
Decentralized Pallet Stop
Acts as an independent pallet arrestor on a packaging line, saving manifold slots while providing 528 N pull at 0.5 MPa.
Remote Tooling Actuator
Drives a clamping arm on a remote station with its self-contained 4M210 valve, simplifying machine plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700-06B the Right Choice?
Size by checking both neighboring bores: the 32 mm bore yields 402 N push at 0.5 MPa, while the 50 mm bore yields 982 N. This 40 mm unit provides 628 N push. Confirm the DC24V terminal entry and PT thread before ordering. The default action retracts the rod when energized, but repositioning the valve switches it to extend-when-energized. Because the valve only routes air, it is not a load lock; add an external rod lock or pilot-operated check valve to hold loads. With a 700 mm 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 SAUF40X700-06B FAQ
It pushes 628 N and pulls 528 N at 0.5 MPa. The built-in 4M210-06 valve has a 1/8" port, Cv 0.78, and runs at 5 cycles/s. The DC24V coil operates at 0.15-0.8 MPa. Although the cylinder body rates to 1.0 MPa, the assembled unit must stay within the 0.15-0.8 MPa valve window.
No remote valve is needed; the integrated 4M210 valve switches the cylinder from one coil signal. However, the valve only routes air and 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. Note that without the -S suffix, this SKU cannot take a magnetic switch.
