Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 1000mm 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 SAUF50X1000-08B
The AirTAC SAUF50X1000-08B is a double-acting profile 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 makes it shorter than an ISO 15552 cylinder of the same bore. This 50mm bore uses a 1/4" cylinder port, a M16x1.5 rod thread, and 21mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers 982N push at 0.5MPa. The DC24V terminal entry coil offers IP65 protection and switches at up to 5 cycles/s. Computed buyer insight: safe working load is ~589N (60% of the 0.5MPa push), yielding a ~50kg vertical lift capacity with a 2:1 margin. Note this SKU lacks the S magnet, so it cannot take 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 SAUF50X1000-08B Is Used
Long-Stroke Diverting
Drives a 1000mm diverting arm on a conveyor line directly from one coil signal, removing the need to run long tubing back to a central manifold.
Decentralized Pusher
Acts as a standalone package pusher at a sorting node, using the integrated 4M210-08 valve to save manifold space and simplify installation.
Machine Gating
Powers a safety gate actuator on a large machine, benefiting from the compact profile and self-contained 5/2 valve for fast local response.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000-08B the Right Choice?
Size this 50mm bore against the 63mm option (1559N push at 0.5MPa) or the 40mm option (628N push) to match your load. The safe working load is ~589N. Confirm the DC24V terminal entry and PT threads suit your control panel. The default action retracts the rod when energised; reposition the valve to extend-when-energised. Size force strictly within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold a load. For this 1000mm stroke, use an external guide to prevent rod bending and side-load wear.
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 SAUF50X1000-08B FAQ
It pushes 982N and pulls 825N at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s max) driven by a DC24V terminal coil. You must size force within the 0.15-0.8 MPa valve operating window, even though the cylinder body rates to 1.0 MPa.
Yes, the default action retracts the rod when energised, but you can reposition the valve to extend-when-energised. The valve only routes air; it is not a load lock. The piston will drift on air loss, so install an external rod lock or pilot-operated check valve if you need to hold a load.
