Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500S-08B 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-08B
The SAUF80X500S-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 version features a 3/8" cylinder port, a 1/4" valve port, and a 500mm stroke with a piston magnet for switches.
Operating within the 0.15-0.8 MPa valve window, it delivers 2513N push force at 0.5 MPa. The safe working load is roughly 1508N, allowing a vertical lift of about 128kg with a 2:1 margin. The integrated valve flows 25 mm2 (Cv 1.4) at up to 4 cycles per second. The DC24V terminal coil offers IP65 protection and a 0.05s response time.

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-08B Is Used
Decentralized Divert Gate
Drives a sorting flap directly at the lane, using one DC24V signal to switch the local 4M310 valve without running long tubing to a central manifold.
Vertical Lift Station
Lifts 128kg loads with a 2:1 safety margin at 0.5 MPa, ideal for independent shelf-access platforms where saving manifold slots simplifies wiring.
Independent Clamp Fixture
Holds workpieces on a large machining bed, switching itself locally to eliminate pneumatic lag from a remote valve island over the 500mm stroke.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500S-08B the Right Choice?
When sizing, compare both neighboring bores: the 63mm bore yields 1559N push while the 100mm bore yields 3927N push at 0.5 MPa. This 80mm bore provides 2513N push and 2268N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve operating range, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT thread meet your electrical specs. The rod retracts when energized by default, but you can reposition the valve to extend on signal. For this 500mm stroke, use external guides to prevent rod bending and side-load wear. To hold a load securely 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-08B FAQ
It generates 2513N push and 2268N pull at 0.5 MPa, reaching 4021N at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25 mm2 flow) with a DC24V terminal coil. Because the valve operates at 0.15-0.8 MPa, size the assembled cylinder within this window, not the 1.0 MPa body rating.
By default the rod retracts when energized. You can reconfigure it to extend-when-energized simply by repositioning the built-in valve. This self-switching design means one coil signal controls the actuator directly, requiring no separate remote valve.
