Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 900mm stroke and a built-in 4M310-08 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 SAUF80X900-08B
The SAUF80X900-08B is a double-acting profile-type cylinder with a built-in AirTAC 4M310-08 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 unit of the same bore. This SKU lacks a magnet (-S), so it cannot take a magnetic switch.
It delivers 2513 N push and 2268 N pull at 0.5 MPa. The safe working load is roughly 1508 N, yielding a vertical lift capacity of about 128 kg with a 2:1 margin. The integrated valve has a 1/4" port, Cv 1.4, and runs at 4 cycles/s. The cylinder body rates to 1.0 MPa, but the valve limits the assembled unit to a 0.15-0.8 MPa window. The bore uses a 3/8" cylinder port and a Ø25 mm rod with an M20x1.5 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 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 SAUF80X900-08B Is Used
Sorting Diverter
Drives a large diverter arm on a high-speed package line using a single DC24V signal without needing a remote valve manifold.
Vertical Gate Actuator
Lifts a loading dock gate, leveraging the 128 kg vertical lift capacity while saving tubing in decentralized stations.
Long-Stroke Pusher
Indexes heavy pallets over the 900 mm travel, relying on the 28 mm adjustable cushions to decelerate the load smoothly.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900-08B the Right Choice?
Size by comparing the 80 mm bore (2513 N push at 0.5 MPa) against the 63 mm (1559 N) and 100 mm (3927 N) options. The coil is DC24V with terminal entry and PT threads. The rod retracts when energized by default; reposition the valve to extend on signal. Because the valve routes air, it is not a lock—add an external rod lock or pilot-operated check valve for held loads. Size all force within the 0.15-0.8 MPa valve range. The 900 mm stroke requires external guides to prevent rod bending under side loads.
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 SAUF80X900-08B FAQ
It generates 2513 N push at 0.5 MPa using a built-in 4M310-08 valve (1/4" port, Cv 1.4, 4 cycles/s). The DC24V coil operates at 0.15-0.8 MPa. Although the cylinder body rates to 1.0 MPa, the assembled unit is limited by the valve to 0.8 MPa.
The rod retracts when the coil is energized, but you can reposition the valve to extend on signal. 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 position.
