Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150-06B 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 SAUF50X150-06B
The SAUF50X150-06B is a double-acting profile-type cylinder with a built-in AirTAC 4M210 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 cylinder of the same bore. It features a 50mm bore, 150mm stroke, 1/4" cylinder port, and an M16x1.5 rod thread.
Operating strictly within the 0.15-0.8 MPa valve window, it generates 982 N push and 825 N pull at 0.5 MPa. The integrated 4M210-06 valve has a 1/8" valve port, Cv 0.78, and handles up to 5 cycles per second. The DC24V coil offers IP65 protection with terminal entry. For sizing, the safe working load is roughly 589 N, and it can vertically lift about 50 kg with a 2:1 margin. Note this SKU lacks the S suffix, 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 (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 SAUF50X150-06B Is Used
Decentralized Conveyor Diverters
Ideal for routing packages on a conveyor line where running individual air lines back to a central manifold is impractical.
Independent Clamping Stations
Perfect for multi-station machining beds, allowing each clamp to actuate independently from a single electrical signal.
Compact Assembly Actuators
Fits neatly into tight machine cells, using the built-in valve to minimize pneumatic tubing across the factory floor.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150-06B the Right Choice?
When sizing, compare neighboring bores: a 40mm bore provides 628 N push while a 63mm bore yields 1559 N at 0.5 MPa. This 50mm bore provides 982 N push. Always confirm the DC24V coil and terminal entry match your control system. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Size forces within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold loads safely. For this 150mm stroke, ensure standard guidance 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 SAUF50X150-06B FAQ
It delivers 982 N push and 825 N pull at 0.5 MPa, reaching 1570 N push at the 0.8 MPa maximum. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) driven by a DC24V terminal-entry coil. You must size the force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
No, the built-in 5/2 valve routes air but does not lock the piston. If air is lost, the load will drift. To maintain a vertical position safely, you must install an external rod lock or a pilot-operated check valve.
