Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700S-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 SAUF40X700S-06B
The SAUF40X700S-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 is shorter than an ISO 15552 cylinder of the same bore. This 40mm bore unit pushes 628N and pulls 528N at 0.5MPa, operating within the 0.15-0.8MPa valve window.
It uses a 4M210-06 valve with a 1/8" port, 14mm2 flow (Cv 0.78), and 5 cycles/s max. The DC24V coil has terminal entry, IP65 rating, and a 0.05s response. The cylinder port is 1/4". Computed sizing: safe working load is 377N (60% of the 0.5MPa push), and vertical lift is 32kg with a 2:1 margin. The S suffix provides a piston magnet for CMSG/DMSG/EMSG switches.

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 SAUF40X700S-06B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate on a long conveyor line. One DC24V signal actuates the 700mm stroke without routing tubing back to a central manifold.
Independent Pallet Stop
Acts as a standalone pallet stop in a large facility. The integrated 4M210 valve simplifies installation and eliminates the need for a nearby valve island.
Remote Machine Guard Gate
Drives a 700mm safety guard gate on a remote machine section. The self-contained air logic saves plumbing and uses an S-suffix magnet for position feedback.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700S-06B the Right Choice?
Size by comparing neighbors: a 32mm bore pushes 402N, while a 50mm bore pushes 982N at 0.5MPa. This 40mm bore yields 628N push and 528N pull at 0.5MPa. Confirm the DC24V coil and terminal entry suit your control system. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8MPa valve limit, not the 1.0MPa cylinder body rating. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads. For the 700mm stroke, use external guides 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 SAUF40X700S-06B FAQ
It pushes 628N and pulls 528N at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s) running on DC24V. The cylinder body rates to 1.0MPa, but you must size force within the 0.15-0.8MPa operating window of the assembled valve.
Yes. The default action retracts the rod when energized, but you can reposition the built-in valve to extend the rod on signal. Because the valve only routes air, it is not a load lock; use an external rod lock or pilot-operated check valve for holding.
