Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75S-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 75mm 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 SAUF40X75S-06B
The SAUF40X75S-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. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
The 40mm bore (1/4" cylinder port, M12x1.25 rod thread) delivers 628N push and 528N pull at 0.5MPa. A safe working load is roughly 377N, allowing a 32kg 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 coil is DC24V with terminal entry. Size forces within the 0.15-0.8MPa valve window, not the 1.0MPa cylinder body rating.

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 SAUF40X75S-06B Is Used
Modular Assembly Cells
Distributes independent clamping actions across a large fixture without routing long tube lines back to a central manifold.
Diverter Gates
Provides localized package routing on conveyors where installing a remote valve island is impractical.
Independent Pick-and-Place
Drives individual gripper actions on decentralized robots, saving manifold space and simplifying wiring.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75S-06B the Right Choice?
Size by checking both neighbouring bores: the 32mm bore yields 402N push at 0.5MPa, while the 50mm bore yields 982N. This 40mm actuator provides 628N push at 0.5MPa. Confirm your coil is DC24V with terminal entry before ordering. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. Because the integrated valve routes air, it cannot hold a load on pressure loss—install an external rod lock or pilot-operated check valve for suspended loads. Keep operating pressure between 0.15-0.8MPa. For this 75mm stroke side-load is minimal, but any stroke over 300mm requires a guide to prevent rod binding.
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 SAUF40X75S-06B FAQ
It delivers 628N push and 528N pull at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max). The coil is DC24V (IP65, terminal entry). The cylinder body rates to 1.0MPa, but you must size forces within the 0.15-0.8MPa valve operating window.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The 5/2 valve only routes air; it is not a lock. The piston will drift on air loss, so use an external rod lock or pilot-operated check valve for suspended loads.
