Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800S-08B is a genuine double-acting profile-type cylinder with a Ø80mm 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 SAUF80X800S-08B
The SAUF80X800S-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 cylinder of the same bore. This 80mm bore unit has a 3/8" cylinder port, an M20x1.5 rod thread, and a 28mm adjustable cushion.
It operates on a DC24V terminal-entry coil (IP65, 3.0W) with a 1/4" valve port flow of 25 mm2 (Cv 1.4) and a 4 cycle/s limit. The cylinder body rates to 1.0 MPa, but the integrated valve restricts the assembled working pressure to 0.15-0.8 MPa. At 0.5 MPa it pushes 2513 N and pulls 2268 N. For sizing, the safe working load is roughly 1508 N, and it can vertically lift about 128 kg with a 2:1 margin. The S suffix provides a piston magnet for CMSG/DMSG/EMSG sensors.

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-08B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate to push packages, needing only a DC24V signal and a 1/4" air supply without a central manifold.
Independent Pallet Stop
A standalone 800mm stroke actuator for pallet handling lanes, saving tubing runs back to a main control cabinet.
Machine Guard Gate
Drives a long-stroke access door with its integrated 4M310 valve, simplifying installation on large machine frames.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X800S-08B the Right Choice?
Size by force across the 0.15-0.8 MPa valve window: this 80mm bore pushes 2513 N at 0.5 MPa, while the neighboring 63mm bore pushes 1559 N and the 100mm pushes 3927 N. Confirm the DC24V terminal entry and PT threads suit your control panel. The rod retracts when the coil is energized, but you can reposition the valve to extend-when-energized. The valve routes air and is not a lock; if power or air is lost the piston drifts, so add an external rod lock or pilot-operated check valve to hold a load. Because the 800mm stroke exceeds 300mm, use external guides to prevent rod bending and side-load damage.
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-08B 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 4M310-08 (Cv 1.4, 25 mm2 flow, 4 cycles/s max) on a 1/4" port with a DC24V coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
Yes, the default action retracts the rod when the coil is energized, but you can reposition the valve to extend-when-energized. The valve only routes air; it does not lock the piston. On air loss the rod drifts, so install an external rod lock or pilot-operated check valve for load holding.
