Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X200S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X200S-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 SAUF80X200S-08B
The SAUF80X200S-08B is a double-acting profile 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 is shorter than an ISO 15552 unit of the same bore. This 80mm bore delivers 2513N push and 2268N pull at 0.5MPa, with a 3/8" cylinder port and an M20x1.5 rod thread.
The integrated valve provides 1/4" porting with a 25mm2 flow (Cv 1.4) and switches up to 4 cycles per second. The DC24V terminal coil offers IP65 protection with a 0.05s response. Size force within the 0.15-0.8MPa valve window, even though the cylinder body rates to 1.0MPa. The S suffix provides a piston magnet for CMSG/DMSG/EMSG switches. Based on the 0.5MPa push force, the safe working load is about 1508N, allowing a vertical lift of roughly 128kg with a 2:1 margin.

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 SAUF80X200S-08B Is Used
Decentralized Conveyor Diverter
Mounts directly at a lane diverter on a conveyor line. The integrated DC24V valve switches the 80mm bore locally, removing the need to run long tubing back to a central manifold.
Machine Tool Clamp
Provides standalone clamping force on a large machining center. The built-in 4M310-08 valve delivers 4021N push at 0.8MPa right at the point of operation without consuming manifold space.
Vertical Package Stop
Acts as a heavy-duty stop gate in a high-flow packaging hub. The self-contained 5/2 valve handles 4 cycles per second, while the S suffix magnet tracks position for the controller.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X200S-08B the Right Choice?
Select between this 80mm bore (2513N push at 0.5MPa) and the 63mm bore (1559N) or 100mm bore (3927N) based on your force requirement. The 200mm stroke is well within the 1500mm maximum and above the 75mm minimum for this bore. Confirm the DC24V terminal coil and PT thread suit your control system. The rod retracts when the coil is energised by default, but you can reposition the valve to extend on energisation. Because the built-in valve routes air rather than locking it, add an external rod lock or pilot-operated check valve if you must hold a load without air. For this 200mm stroke, ensure external guidance to manage 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 SAUF80X200S-08B FAQ
It generates 2513N push and 2268N pull at 0.5MPa, reaching 4021N push at 0.8MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port, Cv 1.4, and a DC24V terminal coil. You must size force within the valve's 0.15-0.8MPa operating window, not the 1.0MPa cylinder body rating.
No, the built-in valve routes air and is not a lock; the piston will drift without pressure. Add an external rod lock or pilot-operated check valve for load holding. By default the rod retracts when the coil is energised, but you can reposition the valve to extend on energisation.
