Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 900mm 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 SAUF50X900-08A
The SAUF50X900-08A 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 uses terminal entry, PT threads, and Ø8xØ5 PU tubing.
It pushes 982 N and pulls 825 N at 0.5 MPa. The integrated valve flows 16 mm2 (Cv 0.89) at 1/4" and handles 5 cycles/sec. Because the valve limits pressure to 0.15-0.8 MPa, size within that window. Computed buyer insight: safe working load is ~589 N (60% of the 0.5 MPa push), allowing a vertical lift of ~50 kg with a 2:1 margin. The 50 mm bore uses a 1/4" cylinder port and an M16x1.5 rod 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 SAUF50X900-08A Is Used
Decentralized Conveyor Diverter
Mounts directly on the line to push packages, using its built-in valve to switch locally without a central manifold.
Long-Reach Vertical Gate
Uses the 900 mm stroke to open tall material gates, saving tubing by actuating from a single AC220V signal.
Independent Machine Clamp
Provides isolated clamping on a large machine bed, freeing up manifold slots while delivering 982 N push.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900-08A the Right Choice?
Size against the 63 mm bore (1559 N push @0.5 MPa) if you need more force, or the 40 mm bore (628 N) for lighter loads. This 50 mm bore provides 982 N push at 0.5 MPa. The AC220V coil uses terminal entry; confirm voltage before ordering. Default action retracts the rod when energised, but you can reposition the valve to extend on signal. The cylinder body rates to 1.0 MPa, but the assembled SAUF must run at 0.15-0.8 MPa. The built-in valve routes air and is not a lock—add an external rod lock or pilot-operated check valve for load holding. For the 900 mm stroke, use external guides to prevent rod bending and side-load damage. This SKU lacks a magnet and cannot take a sensor.
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 SAUF50X900-08A FAQ
It delivers 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) with an AC220V 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, the built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads. By default the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This one-signal switching eliminates the need for a remote valve.
