Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500S-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500S-10B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 500mm 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 SAUF80X500S-10B
The SAUF80X500S-10B is a double-acting profile cylinder with a built-in AirTAC 4M310-10 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 cylinder of the same bore. It features a 500mm stroke with a piston magnet for CMSG/DMSG/EMSG switches.
The integrated valve delivers a 3/8" port, 30mm2 flow (Cv 1.68), and runs up to 4 cycles/sec. The cylinder body rates to 1.0MPa, but you must size force within the valve's 0.15-0.8MPa operating window. At 0.5MPa it pushes 2513N and pulls 2268N. A practical computed insight: safe working load is roughly 1508N (60% of the 0.5MPa push), allowing a vertical lift of about 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 SAUF80X500S-10B Is Used
Sorting Diverter
Decentralized package sorting where one coil signal per diverter saves manifold space and tubing runs on a long conveyor line.
Vertical Lift Gate
Independent lifting gates in a storage system driven directly at the actuator, leveraging the 128kg vertical lift capacity safely.
Machine Tool Clamp
Remote clamping stations on a large machine tool, using the built-in 4M310-10 valve to switch locally without a central manifold.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500S-10B the Right Choice?
When sizing, compare both ways: the 63mm bore neighbor pushes 1559N at 0.5MPa, while the 100mm bore pushes 3927N. This 80mm bore (3/8" air port, M20x1.5 rod thread) provides 2513N push at 0.5MPa. Confirm your coil is DC24V with terminal entry. The rod retracts when energized by default, but you can reposition the valve to extend on signal. Because the 500mm stroke exceeds 300mm, use external guides to prevent rod bending and side-load wear. The valve routes air but is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve.
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-10B FAQ
It pushes 2513N and pulls 2268N at 0.5MPa, reaching 4021N at 0.8MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, 4 cycles/sec max) running on DC24V. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
Yes. The default action retracts the rod when energized, but you can reconfigure it to extend-when-energized simply by repositioning the built-in valve. This self-switching design means no remote valve is needed, saving tubing and installation time.
