Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 160mm stroke and a built-in 4M210-08 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 SAUF40X160-08A
The SAUF40X160-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 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 unit of the same bore. It features a 1/4" cylinder port, an M12x1.25 rod thread, and 21mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa window, this 40mm bore generates 628N push and 528N pull at 0.5 MPa. The integrated valve flows 16 mm2 (Cv 0.89) and cycles up to 5 times per second. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 377N, capable of a 32kg vertical lift with a 2:1 margin.

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 SAUF40X160-08A Is Used
Conveyor Diverter Gate
Self-switching actuation lets a diverter flap fire independently at multiple points along a line without routing long tubes back to a central manifold.
Decentralized Pallet Stop
A single AC220V signal raises and lowers a pallet stop, saving manifold space while delivering 628N of push force at 0.5 MPa.
Independent Clamping Station
Ideal for a standalone clamping fixture where installing a remote valve would add unnecessary plumbing complexity.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X160-08A the Right Choice?
When sizing, compare neighbouring bores: a 32mm bore yields 402N push while a 50mm bore yields 982N push at 0.5 MPa. This 40mm bore provides 628N push, making it ideal for medium loads. Confirm your coil voltage (AC220V) and terminal entry match your control system. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve limit, not the 1.0 MPa cylinder body rating. This SKU lacks a magnet and cannot accept a sensor. The valve routes air and is not a load lock; for held loads add an external rod lock or pilot-operated check valve. For this 160mm stroke, ensure adequate side-load guidance.
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 SAUF40X160-08A FAQ
It generates 628N push and 528N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89) with an AC220V terminal entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa range.
Yes. The default action retracts the rod when energised, but you can reposition the built-in valve to make the rod extend upon energisation. Because this SKU lacks a magnet, it cannot accept position sensors.
