Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125S-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 125mm 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 SAUF80X125S-08A
The AirTAC SAUF80X125S-08A is a double-acting profile cylinder with a built-in 4M310-08 5/2 solenoid valve on the cap. One AC220V 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. This 80mm bore has a 3/8 inch air port, a 25mm rod, and a 125mm stroke.
The integrated valve delivers a 1/4 inch port with 25 mm2 flow (Cv 1.4) and cycles up to 4 times per second. The cylinder body rates to 1.0 MPa, but the assembled unit operates within the 0.15-0.8 MPa valve window. At 0.5 MPa it pushes 2513 N and pulls 2268 N. A computed buyer insight: the safe working load is roughly 1508 N, and it can vertically lift about 128 kg with a 2:1 margin. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.

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 SAUF80X125S-08A Is Used
Machine Tool Clamping
Decentralized clamping on a large machining center. The built-in valve provides rapid 4 cycle/sec actuation right at the fixture without long tubing runs.
Transfer Line Diverters
Independent diverting arms on a high-speed conveyor. One coil signal per actuator simplifies control and eliminates a central valve manifold.
Packaging Pushers
Carton pushing stations on a packaging line. The compact profile saves space while the integrated magnet allows precise position confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125S-08A the Right Choice?
Size this 80mm bore against the neighboring 63mm and 100mm options. At 0.5 MPa the 63mm pushes 1559 N, the 80mm pushes 2513 N, and the 100mm pushes 3927 N. Confirm the AC220V terminal entry and PT thread. The rod retracts by default when energized; reposition the valve to switch to extend-when-energised. Always size force within the 0.15-0.8 MPa valve limit, never the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a lock. For a held load on air loss, add an external rod lock or pilot-operated check valve. For this 125mm stroke side-load is minimal, but for strokes over 300mm add a guide to prevent rod bending.
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-08A FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4 inch port, Cv 1.4, and a 4 cycle/sec max frequency. The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve on the cap. This self-switching design means one coil signal drives the cylinder without needing a separate remote valve.
