Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225S-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 225mm 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 SAUF80X225S-08B
The SAUF80X225S-08B is a double-acting profile cylinder with a built-in AirTAC 4M310 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 cylinder of the same bore. It includes a piston magnet for CMSG/DMSG/EMSG switches.
Operating within the 0.15-0.8 MPa valve window, it delivers a 2513 N push force at 0.5 MPa. The 4M310-08 valve features a 1/4" port, Cv 1.4 flow, and runs up to 4 cycles/s. The DC24V terminal coil is IP65 rated. For sizing, the safe working load is roughly 1508 N, translating to a 128 kg vertical lift with a 2:1 margin. The cylinder bore uses a 3/8" port and a 28 mm adjustable cushion.

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-08B Is Used
Decentralized Divert Gate
Actuates a routing flap directly on the conveyor frame with one coil signal, removing the need to run long tubing back to a central manifold.
Independent Stack Pusher
Drives a carton pusher in a packing cell using its integrated 4M310 valve, freeing up manifold slots for other machine functions.
Compact Clamp Station
Clamps heavy parts at a machining cell where space is tight, leveraging the shorter profile barrel and onboard DC24V solenoid.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225S-08B the Right Choice?
Size by comparing neighbor bores: the 63 mm bore gives 1559 N push at 0.5 MPa, while the 100 mm bore gives 3927 N. This 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, peaking at 4021 N push at 0.8 MPa. Confirm the DC24V terminal entry and PT threads meet your control specs. Default action retracts the rod when energized, but repositioning the valve switches it to extend-when-energized. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. For this 225 mm stroke, ensure adequate side-load guidance.
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-08B FAQ
It generates 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 4M310-08 (1/4" port, Cv 1.4, 4 cycles/s) driven by a DC24V terminal coil. You must size the force within the 0.15-0.8 MPa valve operating window, even though the cylinder body rates to 1.0 MPa.
Yes. The default action retracts the rod when the coil is energized, but you can reposition the valve to make it extend-when-energized. The valve only routes air and is not a lock; the piston will drift on air loss. For load holding, install an external rod lock or pilot-operated check valve.
