Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X250S-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X250S-10A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 250mm 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 SAUF80X250S-10A
The SAUF80X250S-10A is a double-acting profile cylinder with a built-in AirTAC 4M310-10 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 makes it shorter than an ISO 15552 unit of the same bore. The bore sets the 3/8" cylinder port and M20x1.5 rod thread, while the valve features a 3/8" port, 30 mm2 flow (Cv 1.68), and a 4 cycle/s limit.
Operate the assembled unit within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. At 0.5 MPa it delivers 2513 N push and 2268 N pull. A computed buyer insight gives a safe working load of roughly 1508 N (about 60% of the 0.5 MPa push figure), translating to a 128 kg vertical lift with a 2:1 margin. This AC220V terminal-entry version includes a piston magnet for CMSG/DMSG/EMSG switches and uses Ø10xØ6.5 PU tubing.

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 SAUF80X250S-10A Is Used
Package Diverter Gate
Decentralized diverter on a high-speed conveyor. The built-in valve routes air locally, eliminating long tubing runs back to a central manifold.
Pallet Stopper Arm
Independent pallet stopping station. One AC220V coil signal actuates the 80 mm bore to provide 2513 N of holding force at 0.5 MPa.
Machine Tool Clamp
Remote clamping fixture on a large machining center. The integrated 4M310-10 valve saves a manifold slot and simplifies installation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X250S-10A the Right Choice?
Size force between the 63 mm bore (1559 N push @0.5 MPa) and 100 mm bore (3927 N push @0.5 MPa) neighbors; this 80 mm bore gives 2513 N push at 0.5 MPa. Confirm the AC220V terminal entry and PT threads match your control panel. The rod retracts when the coil energises, but you can reposition the valve to extend-when-energised. Size pressure within the 0.15-0.8 MPa valve range. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 250 mm stroke, ensure external side-load guidance to prevent rod wear.
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 SAUF80X250S-10A 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 4M310-10 5/2 solenoid with a 3/8" port, Cv 1.68, and 4 cycle/s max. The coil is AC220V with terminal entry. Size the assembled unit within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised by repositioning the built-in valve. Because the valve only routes air, it cannot hold a load on air loss; install an external rod lock or pilot-operated check valve if load holding is required.
