Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160S-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 160mm 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 SAUF40X160S-06A
The SAUF40X160S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One coil signal drives the rod, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. This 40mm bore pushes 628N and pulls 528N at 0.5MPa, operating inside the 0.15-0.8MPa valve window. The cylinder port is 1/4" and the valve port is 1/8".
The integrated valve flows 14mm2 (Cv 0.78) at up to 5 cycles/sec. It uses an AC220V terminal-entry coil (IP65, class B, 0.05s response). The piston rod is Ø16mm with an M12x1.25 thread and 21mm adjustable cushions. A computed buyer insight: safe working load is roughly 377N (60% of the 0.5MPa push), suiting a vertical lift of about 32kg with a 2:1 margin. The -S suffix denotes 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 SAUF40X160S-06A Is Used
Decentralized Clamping Station
Drives a clamping arm directly at the fixture using one AC220V signal, removing the need to run long tubing back to a central manifold.
Inline Divert Gate
Switches a divert flap on a conveyor line independently, leveraging the 5 cycles/sec valve speed for rapid package routing.
Compact Vertical Lift
Lifts a 32kg payload vertically with a 2:1 safety margin, saving manifold space in tight distribution machinery cabinets.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160S-06A the Right Choice?
Size force across the 0.15-0.8MPa valve range: this 40mm bore yields 628N push at 0.5MPa, while the neighbouring 50mm bore yields 982N. Confirm the AC220V terminal entry and 1/8" valve port suit your supply. Default action retracts the rod when energised; reposition the valve to extend-when-energised. The cylinder body rates to 1.0MPa but the assembled SAUF must operate at 0.15-0.8MPa. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 160mm stroke, guide the mechanism to manage 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 SAUF40X160S-06A FAQ
It delivers 628N push and 528N pull at 0.5MPa, using a built-in 4M210-06 valve (1/8" port, Cv 0.78, 5 cycles/sec) on an AC220V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the 0.15-0.8MPa valve window. The cylinder air port is 1/4".
Yes. The default action retracts the rod when energised, but you can reposition the valve to extend-when-energised. The valve only routes air; it is not a load lock. The piston will drift on air loss, so install an external rod lock or pilot-operated check valve if you need to hold a load.
