Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 150mm 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 SAUF50X150-08A
The SAUF50X150-08A 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 valves and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. This 50mm bore has a 1/4" cylinder port, an M16x1.5 rod thread, and 21mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers 982N push at 0.5 MPa. The integrated valve offers 1/4" porting, Cv 0.89, and 5 cycles/sec. For sizing, the safe working load is roughly 589N (60% of the 0.5MPa push), allowing a 50kg vertical lift with a 2:1 margin. This AC220V terminal-entry coil is IP65 rated. Note this SKU lacks the -S magnet and cannot take a sensor.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAUF50X150-08A Is Used
Decentralized Clamping
Ideal for a multi-station machining line where each clamp needs its own actuation without routing long tubing back to a central manifold.
Inline Diverters
Perfect for conveyor sorting gates that require independent, rapid cycling up to 5 cycles/sec directly at the divert point.
Compact Package Stops
Suits tight warehouse packaging frames where the short profile barrel and integrated valve save valuable mounting space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150-08A the Right Choice?
When sizing, compare neighbours: the 40mm bore pushes 628N and the 63mm pushes 1559N at 0.5 MPa. This 50mm bore gives 982N push and 825N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry suits your supply. Default action retracts the rod when energised; reposition the valve to extend on signal. For this 150mm stroke, guide the load to manage side-load forces. The valve routes air but does not hold the load on pressure loss—add an external rod lock or pilot-operated check valve for suspended loads. Without the -S suffix, this cylinder cannot host magnetic switches.
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 SAUF50X150-08A FAQ
It pushes 982N and pulls 825N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec). The cylinder body rates to 1.0 MPa, but you must size force within the 0.15-0.8 MPa valve operating window. The coil is AC220V with terminal entry.
Yes. The default action retracts the rod when energised, but you can reposition the built-in valve to make the rod extend on signal. This single-coil setup removes the need for a remote valve, though the valve only routes air and will not hold a load without pressure.
