Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X80-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X80-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 80mm 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 SAUF80X80-08B
The SAUF80X80-08B 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 unit of the same bore. This 80mm bore delivers 2513N push at 0.5MPa, and the 3/8" cylinder port feeds a 1/4" valve port with 25mm2 flow (Cv 1.4) cycling up to 4 times per second.
Operating on DC24V terminal entry, the coil is IP65 rated with a 0.05s response. The cylinder body rates to 1.0MPa, but the integrated valve restricts the assembled working pressure to 0.15-0.8MPa. Based on the 0.5MPa push force, the computed safe working load is 1508N, translating to a 128kg vertical lift with a 2:1 margin. This SKU lacks a magnet and cannot accept a sensor.

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 SAUF80X80-08B Is Used
Decentralized Clamping Press
Uses the built-in valve to clamp heavy workpieces directly at the station, eliminating long tube runs back to a central manifold.
Inline Divert Gate
Switches packages on a high-speed belt with one coil signal, leveraging the 4M310-08 valve flow for rapid local actuation.
Independent Lift Station
Lifts pallets in a distributed layout where manifold slots are full, relying on the 128kg vertical lift capacity at 0.5MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X80-08B the Right Choice?
Size this 80mm bore against the 63mm and 100mm neighbors: at 0.5MPa it provides 2513N push and 2268N pull, sitting between the 63mm (1559N) and 100mm (3927N) options. Confirm the DC24V terminal entry and PT threads match your supply. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8MPa valve window, never the 1.0MPa cylinder rating. The valve only routes air; for load holding on air loss, add an external rod lock or pilot-operated check valve. Since the 80mm stroke is under 300mm, side-load guides are less critical, but always ensure smooth linear motion. Without a magnet suffix, this actuator cannot support magnetic switches.
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 SAUF80X80-08B FAQ
It pushes 2513N and pulls 2268N at 0.5MPa, reaching 4021N push at 0.8MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25mm2 flow) running on DC24V. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the 0.15-0.8MPa valve window.
No, the 5/2 valve only routes air and is not a lock. On pressure loss the piston drifts and the 28mm cushions only decelerate near stroke end. Install an external rod lock or pilot-operated check valve for secure load holding.
