Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X600-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X600-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 600mm 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 SAUF50X600-08B
The AirTAC SAUF50X600-08B is a double-acting profile-type cylinder with a built-in 4M210-08 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 SKU lacks a magnet, so it cannot accept a magnetic switch.
It delivers 982 N push and 825 N pull at 0.5 MPa. The cylinder body rates to 1.0 MPa, but you must size force within the built-in valve's 0.15-0.8 MPa operating window. The 1/4" valve port yields a 16 mm2 flow (Cv 0.89) and handles up to 5 cycles/sec. Computed buyer insight: safe working load is roughly 589 N (about 60% of the 0.5 MPa push), offering a vertical lift capacity of about 50 kg with a 2:1 margin. The bore's cylinder port is 1/4", the rod is Ø20 mm with an M16x1.5 thread, and it uses Ø8xØ5 PU tube.

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 SAUF50X600-08B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate to push packages, switching itself with one DC24V signal and cutting long tubing runs back to a central manifold.
Independent Stack Gate
Ideal for isolated warehouse stops where running a remote valve line is costly; the built-in 4M210 valve handles the 600 mm stroke diverting action locally.
Machine Tool Loading
Drives a 50 kg workpiece lift on a machining cell. The compact profile saves space while the integrated valve simplifies electrical control wiring.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X600-08B the Right Choice?
When sizing, compare neighbouring bores: a 40 mm bore gives 628 N push while a 63 mm bore yields 1559 N at 0.5 MPa. This 50 mm bore provides 982 N push, making the 589 N safe working load ideal for mid-range tasks. Confirm the DC24V terminal entry coil and IP65 rating suit your control panel. Default action retracts the rod when energised; reposition the valve to extend on signal. Always operate within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body limit. Because this is a 600 mm stroke, add external guides to prevent rod bending and side-load wear. The valve routes air but does not lock; for load holding on air loss, install an external rod lock or pilot-operated check valve.
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 SAUF50X600-08B 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/sec) running on a DC24V terminal entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
No remote valve is needed; the integrated 5/2 valve switches the cylinder directly. By default the rod retracts when energised, but you can reposition the valve to extend on signal. The valve only routes air, so it will not hold a load on air loss; add an external rod lock or pilot-operated check valve for vertical holding.
