Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160-06B 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 SAUF40X160-06B
The SAUF40X160-06B is a double-acting profile cylinder featuring an integrated AirTAC 4M210 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. This 40mm bore delivers 628N push and 528N pull at 0.5MPa, operating within the valve's 0.15-0.8MPa range.
The built-in 4M210-06 valve has a 1/8" port, 14mm2 flow (Cv 0.78), and cycles up to 5 times per second. It uses terminal entry with PT threads and connects via Ø8xØ5 PU tubing. For sizing, the safe working load is roughly 377N (about 60% of the 628N push force), allowing a vertical lift of approximately 32kg with a 2:1 margin. Note this SKU lacks the S suffix magnet, 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 SAUF40X160-06B Is Used
Decentralized Clamping Station
Ideal for a machining cell where each clamp needs its own actuator, saving manifold space and simplifying tubing runs with direct DC24V control.
Independent Diverter Gate
Perfect for a conveyor diverter requiring standalone operation, using the built-in 4M210 valve to switch instantly without a remote valve island.
Compact Sorter Pusher
Fits neatly into tight sortation machinery, using the short profile barrel and integrated valve to push packages at up to 5 cycles per second.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160-06B the Right Choice?
When sizing, compare neighbouring bores: a 32mm bore yields 402N push at 0.5MPa, while a 50mm bore provides 982N. This 40mm bore gives 628N push and 528N pull at 0.5MPa. Always size force within the assembled valve's 0.15-0.8MPa operating window, never the 1.0MPa cylinder body rating. Confirm the DC24V terminal entry coil meets your supply. By default the rod retracts when energised; you can reconfigure it to extend by repositioning the valve. The built-in valve routes air and is not a load lock—add an external rod lock or pilot-operated check valve to hold a load. For this 160mm stroke, side-load guides are recommended.
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 SAUF40X160-06B 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) running on a DC24V terminal entry coil. You must size the force within the valve's 0.15-0.8MPa operating window, even though the cylinder body rates to 1.0MPa. The cylinder air port is 1/4".
No, the built-in valve only routes air and is not a lock; the piston will drift on air loss. For vertical holding, add an external rod lock or pilot-operated check valve. Additionally, this specific SKU lacks the magnet suffix, so it cannot accept a magnetic switch.
