Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X200-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X200-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 200mm 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 SAUF80X200-08B
The SAUF80X200-08B is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. It features a Ø25 mm rod, M20x1.5 rod thread, 3/8" cylinder port, and 28 mm adjustable cushions.
Operating pressure is 0.15-0.8 MPa because the integrated valve dictates the limit, not the 1.0 MPa cylinder body. At 0.5 MPa it delivers 2513 N push force. For sizing, the safe working load is roughly 1508 N, and it can vertically lift about 128 kg with a 2:1 margin. The 1/4" valve port gives 25 mm2 flow (Cv 1.4) at up to 4 cycles per second. This SKU lacks a magnet and cannot take 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 (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 SAUF80X200-08B Is Used
Divert Gate Actuation
Decentralized diverters on a packaging line benefit from one-valve-per-actuator control, eliminating long tubing runs back to a central manifold.
Machine Tool Clamping
Ideal for clamping stations where saving manifold space is critical, letting a single DC24V signal directly drive the 2513 N clamp.
Vertical Lift Stops
Useful for pop-up stops in material handling, providing robust local switching without adding complexity to the main control panel.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X200-08B the Right Choice?
Size this 80 mm bore against the neighbouring 63 mm and 100 mm options. At 0.5 MPa the 63 mm bore yields 1559 N push while the 100 mm bore yields 3927 N, so select the 80 mm bore for loads near its 1508 N safe working capacity. Verify the DC24V terminal entry and PT thread meet your control spec. The rod retracts when the coil is energised, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve window. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 200 mm stroke, ensure external guidance to prevent 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 SAUF80X200-08B FAQ
It generates 2513 N push and 2268 N pull at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25 mm2 flow) running on DC24V. The cylinder body rates to 1.0 MPa, but you must size force within the 0.15-0.8 MPa operating window of the assembled valve.
Yes, you can reposition the valve to make the rod extend when the coil is energised. 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 for load holding.
