Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 500mm 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 SAUF50X500-08B
The SAUF50X500-08B is a double-acting profile cylinder with a built-in AirTAC 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 has no magnet (-S omitted), so it cannot accept a magnetic switch.
It delivers 982 N push and 825 N pull at 0.5 MPa. The safe working load is roughly 589 N, and it can vertically lift about 50 kg with a 2:1 margin. The 1/4" valve port yields a Cv of 0.89 and 5 cycles/sec. The cylinder body rates to 1.0 MPa, but size force within the valve's 0.15-0.8 MPa window. The bore's air port is 1/4" with a PT thread.

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 SAUF50X500-08B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate. One DC24V signal actuates the 500 mm stroke without running long tubing back to a central manifold.
Independent Pusher Station
Ideal for a standalone packaging pusher. The integrated 4M210 valve removes the need for a remote valve island, saving installation time.
Machine Tool Loading
Loads parts into a CNC cell. The compact profile barrel fits tight machine envelopes while providing 982 N of push force at 0.5 MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500-08B the Right Choice?
Size between the 40 mm bore (628 N push @0.5 MPa) and the 63 mm bore (1559 N push @0.5 MPa). This 50 mm bore gives 982 N push at 0.5 MPa. Confirm the DC24V terminal entry and PT thread suit your control panel. The rod retracts when the coil is energised; reposition the valve to switch to extend-when-energised. Because the 4M210 valve only routes air, it is not a load lock—add an external rod lock or pilot-operated check valve to hold a load. For this 500 mm 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 SAUF50X500-08B FAQ
It provides 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). The coil is DC24V with terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit operates at 0.15-0.8 MPa.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The valve only routes air, so it is not a load lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve to hold a load.
