Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125S-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125S-10B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 125mm 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 SAUF80X125S-10B
The SAUF80X125S-10B 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 is shorter than an ISO 15552 cylinder of the same bore. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
It delivers 2513 N push and 2268 N pull at 0.5 MPa. The safe working load is roughly 1508 N, allowing a vertical lift of about 128 kg with a 2:1 margin. The integrated 4M310-10 valve has a 3/8" port, Cv 1.68 flow, and switches up to 4 cycles/s. The cylinder body rates to 1.0 MPa, but size force within the valve's 0.15-0.8 MPa operating window. The bore's air port is 3/8" with a PT thread, and it uses PU tube Ø10xØ6.5.

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)

|---|---|---|
| 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 SAUF80X125S-10B Is Used
Diverter Gate Actuation
Decentralized sorting line diverter where the integrated valve eliminates long tube runs back to a central manifold, allowing rapid local switching up to 4 cycles/s.
Pallet Stopper Station
Independent pallet stopping mechanism on a packaging conveyor; the built-in DC24V valve simplifies control wiring and saves a manifold slot for high-density layouts.
Clamp Fixture Control
Machine tool clamping station requiring a magnet piston for position confirmation; the profile cylinder provides compact 2513 N clamping force at 0.5 MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125S-10B the Right Choice?
Select between the 63 mm bore (1559 N push @0.5 MPa) and the 100 mm bore (3927 N push @0.5 MPa) based on your load. This 80 mm bore provides 2513 N push at 0.5 MPa. Confirm the DC24V terminal entry and PT thread meet your electrical specs. The default action retracts the rod when the coil is energised, but you can reposition the valve to extend on energisation. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body limit. The built-in valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. For this 125 mm stroke, side-load is minimal, but for strokes over 300 mm, use a guide to prevent rod binding.
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 SAUF80X125S-10B FAQ
It generates 2513 N push and 2268 N pull at 0.5 MPa, reaching 4021 N at 0.8 MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, max 4 cycles/s) with a DC24V terminal entry coil (IP65). The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
No, the built-in 5/2 valve routes air but does not lock the piston. On air loss, the load will drift. For vertical load holding, install an external rod lock or pilot-operated check valve. The default action retracts the rod when energised, but you can reposition the valve to extend on energisation.
