Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50-06B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 50mm 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 SAUF32X50-06B
The AirTAC SAUF32X50-06B is a double-acting profile cylinder with a built-in 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 is shorter than an ISO 15552 cylinder of the same bore. This 32mm bore uses a 1/8" cylinder port and a 12mm rod with an M10x1.25 thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 402N push at 0.5 MPa. The integrated 4M210-06 valve has a 1/8" port, 14 mm2 flow (Cv 0.78), and cycles up to 5 times per second. The DC24V coil uses 3.0W with IP65 protection and terminal entry. For sizing, the safe working load is roughly 241N (60% of the 0.5MPa push force), allowing a vertical lift of about 20kg 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 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 SAUF32X50-06B Is Used
Modular Assembly Cells
Distributes individual actuator control across large machines without routing long tube runs back to a central manifold.
Small Part Ejection
Handles compact ejection tasks at up to 5 cycles per second using the integrated 4M210 valve for rapid local switching.
Diverter Gates
Powers lightweight routing flaps directly at the conveyor zone, minimizing response delay with the built-in 5/2 valve.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50-06B the Right Choice?
Size this 32mm bore against the 40mm option (628N push at 0.5 MPa) to ensure adequate force. This DC24V terminal entry model operates at 0.15-0.8 MPa; do not exceed 0.8 MPa despite the 1.0 MPa cylinder body rating. By default the rod retracts when energised, but repositioning the valve changes it to extend-when-energised. This SKU lacks a magnet and cannot accept a magnetic switch. The valve routes air and does not hold loads; add an external rod lock or pilot-operated check valve for drop protection. For strokes over 300mm, use side-load guides.
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 SAUF32X50-06B FAQ
It pushes 402N and pulls 345N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) driven by a DC24V coil. The assembled unit operates strictly within a 0.15-0.8 MPa pressure window.
No. The integrated 5/2 valve routes air but does not lock the piston. If air is lost, the load will drift. You must add an external rod lock or pilot-operated check valve for secure load holding.
