Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 800mm 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 SAUF50X800-08B
The AirTAC SAUF50X800-08B is a double-acting profile cylinder with a built-in 4M210-08 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. The bore uses a 1/4" cylinder port and an M16x1.5 rod thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 982 N push force at 0.5 MPa. The valve flows 16 mm2 (Cv 0.89) at up to 5 cycles/sec. For sizing, the safe working load is roughly 589 N (60% of the 0.5 MPa push), and the vertical lift capacity is about 50 kg with a 2:1 margin. Note this SKU lacks the -S 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 SAUF50X800-08B Is Used
Decentralized Conveyor Divert
Mounts directly on a conveyor diverter arm. One coil signal actuates the 800 mm stroke without routing tubing back to a central manifold.
Long-Reach Pusher Station
Pushes cartons across a transfer zone. The built-in 4M210-08 valve handles the 1/4" port air routing right at the actuator.
Independent Machine Gate
Operates a safety guard on a large machine. The self-contained DC24V valve simplifies installation and saves manifold slots.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800-08B the Right Choice?
Size force between the 40 mm bore (628 N push @0.5 MPa) and 63 mm bore (1559 N push @0.5 MPa). This 50 mm bore gives 982 N push at 0.5 MPa. Always size within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT threads. The rod retracts when energised; reposition the valve to extend on signal. Because the 800 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side-load wear. The valve routes air and is not a lock; for load holding on air loss, add 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 SAUF50X800-08B FAQ
It delivers 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (Cv 0.89, 16 mm2 flow) running on DC24V. Size force within the 0.15-0.8 MPa valve operating window. The 50 mm bore has a 1/4" cylinder port and a 20 mm rod.
By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised by repositioning the built-in valve. This self-switching design means no remote valve is needed, saving tubing and installation time.
