Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X800-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X800-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 800mm 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 SAUF100X800-08A
The SAUF100X800-08A is a double-acting profile cylinder with a built-in AirTAC 4M310 5/2 solenoid valve on the cap. One coil signal drives the actuator, saving tubing and a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. This 100mm bore uses a 1/2" air port and a 25mm rod with an M20x1.5 thread.
It pushes 3927N at 0.5MPa. The safe working load is roughly 2356N, allowing a vertical lift of about 200kg with a 2:1 margin. The integrated valve has a 1/4" port, Cv 1.4, and runs at 4 cycles/s. The coil is AC220V with terminal entry. Because this SKU lacks a magnet, it cannot take a magnetic switch. Size force within the 0.15-0.8MPa valve window, not the 1.0MPa cylinder body rating.

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 (Ø100mm)

|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAUF100X800-08A Is Used
Large Press Ejection
Uses one coil signal to eject heavy parts from a press, eliminating remote valve plumbing and saving manifold space.
Pallet Diverter Gate
Switches a heavy diverter on a packaging line directly at the actuator, simplifying machine layout and tubing runs.
Decentralized Lift Station
Lifts 200kg loads vertically in a storage system using the built-in valve, avoiding a central manifold and long lines.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X800-08A the Right Choice?
This 100mm bore pushes 3927N at 0.5MPa; the neighboring 80mm bore pushes 2513N. Verify your load fits the 0.15-0.8MPa valve operating range. The AC220V terminal entry coil is IP65. Default action retracts the rod when energized; reposition the valve to extend when energized. Without air the valve routes flow but does not lock the piston, so add an external rod lock or pilot-operated check valve to hold a load. For the 800mm stroke, use external guides to prevent rod bending and side loads. Without the -S suffix, this actuator cannot accept 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 SAUF100X800-08A FAQ
It pushes 3927N at 0.5MPa using a built-in 4M310-08 valve with Cv 1.4 and a 1/4" port. The AC220V terminal entry coil operates at 4 cycles/s. Size force within the 0.15-0.8MPa valve window, even though the cylinder body rates to 1.0MPa.
Yes, the default action retracts the rod when energized, but you can reposition the valve to extend when energized. The valve only routes air; it is not a lock. To hold a load on air loss, install an external rod lock or pilot-operated check valve.
