Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150-08B 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 SAUF50X150-08B
The SAUF50X150-08B is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The 50mm bore uses a 1/4" cylinder port with an M16x1.5 rod thread.
The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. Operating pressure is 0.15-0.8 MPa because the integrated valve dictates the limit, not the 1.0 MPa cylinder body. At 0.5 MPa it pushes 982 N and pulls 825 N. A practical safe working load is roughly 589 N, allowing a vertical lift of about 50 kg with a 2:1 margin. This terminal-entry, PT-thread model lacks a magnet and cannot accept 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 SAUF50X150-08B Is Used
Decentralized Conveyor Divert
Mounts directly at a lane diverter on the conveyor frame. One DC24V signal actuates the 150mm stroke without routing tubing back to a central manifold.
Independent Clamping Station
Ideal for a standalone clamping fixture on a large machine bed. The integrated 4M210 valve provides immediate local response without occupying manifold space.
Compact Assembly Gantry
Fits within tight gantry clearances thanks to the short extruded profile. Delivers 982 N push at 0.5 MPa for pressing small bearings into housings.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150-08B the Right Choice?
Size by force: this 50mm bore delivers 982 N push at 0.5 MPa; step down to a 40mm bore for 628 N, or up to a 63mm bore for 1559 N. Confirm the DC24V coil and terminal entry suit your control system. The rod retracts when energised by default, but you can reposition the valve to extend on signal. Because the 4M210 valve limits the assembly to 0.15-0.8 MPa, never size force using the 1.0 MPa cylinder rating. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold a load safely. For this 150mm stroke, guide the mechanism 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 SAUF50X150-08B FAQ
It generates 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s max) running on DC24V. You must size force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
No, this specific SKU lacks a magnet and cannot accept a sensing switch. The 5/2 valve defaults to retracting the rod when the coil is energised, but you can reposition it on the cap to extend-when-energised. It routes air only and is not a load lock.
