Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500S-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 500mm 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 SAUF80X500S-08A
The SAUF80X500S-08A 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. It features a 500mm stroke, a Ø25mm rod, M20x1.5 rod thread, and a 3/8" cylinder port.
Operating within the valve's 0.15-0.8 MPa range, it delivers 2513N push at 0.5MPa. A computed buyer insight: safe working load is ~1508N, allowing a 128kg vertical lift with a 2:1 margin. The integrated valve provides 25mm2 flow (Cv 1.4) at 1/4" and switches up to 4 cycles/sec. This AC220V terminal-entry variant includes a piston magnet for position sensing.

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 SAUF80X500S-08A Is Used
Sorting Diverter
Decentralized diverter gates on a high-speed sorting line use the built-in valve to actuate independently without a central manifold.
Pallet Handling Gate
Controls entry gates in pallet flow systems, saving tubing and simplifying installation across large physical layouts.
Machine Tool Guard
Operates heavy safety doors on machining centers where local switching reduces response time and manifold complexity.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500S-08A the Right Choice?
Size by checking both neighboring bores: the 63mm bore yields 1559N push while the 100mm bore yields 3927N at 0.5MPa. This 80mm bore provides 2513N push and 2268N pull at 0.5MPa. Always size force within the 0.15-0.8 MPa valve window, not the 1.0MPa cylinder body rating. Confirm the AC220V terminal entry meets your electrical specs. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. The 500mm stroke requires external guidance to prevent rod bending under side loads. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the valve only routes air.
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 SAUF80X500S-08A FAQ
It pushes 2513N and pulls 2268N at 0.5MPa. The built-in valve is a 4M310-08 5/2 solenoid with 1/4" port, Cv 1.4, and 4 cycles/sec max. The coil is AC220V with terminal entry. Size force within the 0.15-0.8 MPa valve operating window.
No, the built-in valve only routes air and is not a lock. The rod retracts by default when energized but can be reconfigured to extend. For load holding during air loss, install an external rod lock or pilot-operated check valve.
