Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150S-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 150mm 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 SAUF50X150S-06A
The SAUF50X150S-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 actuator, 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 50mm bore delivers 982N push and 825N pull at 0.5MPa, with a 1/4" cylinder port and an M16x1.5 rod thread.
The integrated valve provides 1/8" porting with a 14mm2 flow (Cv 0.78) and handles up to 5 cycles per second. The AC220V terminal-entry coil is IP65 rated with a response under 0.05s. Size force within the 0.15-0.8MPa valve window, even though the cylinder body rates to 1.0MPa. Based on the 982N push at 0.5MPa, the safe working load is about 589N, translating to a 50kg vertical lift with a 2:1 margin. The -S suffix provides 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 (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 SAUF50X150S-06A Is Used
Decentralized Clamping Station
Eliminates the need for a central valve manifold on a multi-station machining line, driving the clamp directly from one AC220V signal.
Inline Divert Gate
Provides rapid actuation up to 5 cycles per second for a conveyor sorting diverter, saving tubing runs back to a main control panel.
Package Stopper Arm
Uses the built-in magnet for position confirmation while functioning as an independent stopping mechanism on a packing conveyor.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150S-06A the Right Choice?
When sizing, compare this 50mm bore (982N push at 0.5MPa) against the 40mm (628N) and 63mm (1559N) neighbors to match your load. Confirm the AC220V terminal entry and PT threads meet your electrical and plumbing standards. The rod retracts by default when energized, but you can reposition the valve to extend on signal. Always operate within the 0.15-0.8MPa valve pressure range. The integrated valve routes air but does not function as a load lock; for vertical or suspended loads, install an external rod lock or pilot-operated check valve to prevent drift on air loss. For this 150mm stroke, ensure adequate side-load guidance to protect the seal package.
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 SAUF50X150S-06A FAQ
It delivers 982N push and 825N pull at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) driven by an AC220V terminal-entry coil. Although the cylinder body rates to 1.0MPa, you must size force within the assembled valve's 0.15-0.8MPa operating window.
No, the built-in valve only routes air and is not a load lock. If air is lost, the piston will drift. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. For suspended loads, add an external rod lock or pilot-operated check valve.
