Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800S-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800S-10B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 800mm stroke and a built-in 4M310-10 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 SAUF80X800S-10B
The SAUF80X800S-10B is a double-acting profile cylinder with a built-in AirTAC 4M310 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. It features a 3/8" valve port, 3/8" cylinder port, and a piston magnet for position sensing.
The integrated valve flows 30 mm2 (Cv 1.68) at up to 4 cycles per second. Although the cylinder body rates to 1.0 MPa, the valve limits operation to 0.15-0.8 MPa. At 0.5 MPa it pushes 2513 N and pulls 2268 N. A safe working load is roughly 1508 N, yielding a vertical lift capacity of about 128 kg 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 SAUF80X800S-10B Is Used
Long-Stroke Diversion
Drives an 800 mm diverter arm on a conveyor line directly from one coil signal, skipping the main valve manifold.
Decentralized Pallet Gate
Opens and closes a heavy palletizing gate using the built-in 4M310 valve, cutting tubing runs across the cell.
Independent Machine Guard
Actuates a safety guard on a standalone machine station without occupying a slot in the central control manifold.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800S-10B the Right Choice?
Size by force: the 80 mm bore gives 2513 N push at 0.5 MPa; step down to a 63 mm bore for 1559 N, or up to 100 mm for 3927 N. Confirm the DC24V terminal entry and PT threads suit your control panel. The rod retracts by default when energized, but repositioning the valve switches it to extend. Size all forces within the 0.15-0.8 MPa valve window. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold loads safely. For this 800 mm stroke, use external guides to prevent rod bending and 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 SAUF80X800S-10B FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa, reaching 4021 N at 0.8 MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, max 4 cycles/sec). The cylinder body rates to 1.0 MPa, but the assembled unit must operate within the 0.15-0.8 MPa valve window. Coil is DC24V.
Yes. The default action retracts the rod when the coil is energized, but you can reconfigure it to extend-when-energized simply by repositioning the built-in valve. This self-switching design removes the need for a remote valve, saving tubing and installation time.
