Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225S-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225S-10A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 225mm 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 SAUF80X225S-10A
The SAUF80X225S-10A is a double-acting profile cylinder with a built-in AirTAC 4M310 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot in decentralized setups. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. It features a Ø25 mm rod, M20x1.5 rod thread, and a 3/8" cylinder port.
Operating within the valve's 0.15-0.8 MPa window, it delivers 2513 N push force at 0.5 MPa. The 3/8" valve port yields a 30 mm2 flow (Cv 1.68) with a 4 cycle/s limit. The S suffix provides a piston magnet for CMSG/DMSG/EMSG sensors. For sizing, expect a safe working load around 1508 N, or a 128 kg vertical lift 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 SAUF80X225S-10A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate on a large conveyor line. The integrated 4M310 valve switches the actuator from a single AC220V signal, cutting tubing runs back to a central manifold.
Independent Pallet Stopper
Acts as a standalone pallet stop in a high-density warehouse. The built-in valve eliminates manifold slot costs, and the piston magnet supports CMSG sensors for position feedback.
Machine Tool Clamp
Provides single-actuator clamping on a machining line. The 3/8" valve port supplies Cv 1.68 flow for rapid actuation, while the profile barrel saves space compared to standard ISO units.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225S-10A the Right Choice?
When sizing, compare neighbouring bores: the 63 mm bore offers 1559 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. This 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry and PT threads. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Since the 225 mm stroke exceeds 300 mm, ensure external side-load guidance. The valve routes air and 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 SAUF80X225S-10A FAQ
It delivers 2513 N push and 2268 N pull at 0.5 MPa, reaching 4021 N push at 0.8 MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, 4 cycles/s max) driven by an AC220V terminal coil. You must size force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
No. The built-in 4M310 valve routes air; it is not a load lock. If air is lost or the valve is centered, the piston will drift. To hold a load securely, install an external rod lock or a pilot-operated check valve.
