Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125S-08B 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-08B
The AirTAC SAUF80X125S-08B is a double-acting profile cylinder with a built-in 4M310 5-port 2-position solenoid valve on the cap. One 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 cylinder of the same bore.
This 80mm bore unit pushes 2513N and pulls 2268N at 0.5MPa, operating within the valve's 0.15-0.8MPa window. The integrated 4M310-08 valve features a 1/4 inch port, 25mm2 flow (Cv 1.4), and runs up to 4 cycles per second. The DC24V terminal coil offers IP65 protection. A computed buyer insight: safe working load is roughly 1508N (60% of the 0.5MPa push force), yielding a vertical lift capacity of about 128kg 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 SAUF80X125S-08B Is Used
Decentralized Diverters
Drives individual conveyor diverting gates directly from the actuator, removing the need for a central valve manifold and long tubing runs.
Independent Lift Stations
Powers standalone vertical lift stops in a high-density warehouse, using the built-in 4M310 valve to switch each unit independently.
Modular Machine Clamps
Actuates clamping mechanisms on modular assembly cells where installing a remote valve for each cylinder would consume excessive space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125S-08B the Right Choice?
When sizing, compare neighboring bores: the 63mm bore pushes 1559N while the 100mm bore pushes 3927N at 0.5MPa. This 80mm bore provides 2513N push force, so size your load within the 0.15-0.8MPa valve operating range, never the 1.0MPa cylinder body rating. Confirm the DC24V terminal entry and PT thread meet your electrical specs. The rod retracts when energized by default, but you can reposition the valve to extend on signal. Because the valve only routes air, add an external rod lock or pilot-operated check valve if you need to hold a load without air. For this 125mm stroke, side-load guides are not strictly required, but always guide strokes of 300mm or longer.
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-08B FAQ
The 80mm bore generates 2513N push and 2268N pull at 0.5MPa, reaching 4021N at 0.8MPa. It uses a built-in 4M310-08 valve (1/4 inch port, Cv 1.4, 4 cycles/sec max) with a DC24V terminal coil. Size your force within the valve's 0.15-0.8MPa operating window, as the assembled unit cannot run at the 1.0MPa cylinder body rating.
By default, the rod retracts when the coil receives a signal. You can reconfigure it to extend when energized simply by repositioning the built-in valve. This self-switching design means one coil signal drives the cylinder without needing a separate remote valve.
