Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125-08B 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 SAUF80X125-08B
The SAUF80X125-08B 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 in large machines. The 80mm bore delivers 2513N push and 2268N pull at 0.5MPa, operating within the valve's 0.15-0.8MPa window.
The integrated valve offers 1/4" porting with a Cv of 1.4 and cycles up to 4 times per second. It runs on DC24V via terminal entry with IP65 protection. Based on the 0.5MPa push force, the computed safe working load is roughly 1508N, translating to a vertical lift capacity of about 128kg with a 2:1 margin. This SKU lacks a magnet and cannot accept a sensor.

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 SAUF80X125-08B Is Used
Diverter Gate Actuation
Uses the integrated valve to switch a sorting flap directly at the conveyor lane without routing air lines back to a central manifold.
Decentralized Pallet Stop
Deploys a heavy stop block on a roller conveyor; the built-in 4M310 valve provides immediate local response without a remote valve bank.
Machine Tool Clamping
Clamps large castings securely using the 80mm bore force, with the DC24V coil keeping wiring simple at the machining cell.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X125-08B the Right Choice?
Size by comparing the 80mm bore (2513N push at 0.5MPa) against the neighbouring 63mm (1559N) and 100mm (3927N) options. Confirm the DC24V terminal entry and PT thread match your control setup. Size force strictly within the 0.15-0.8MPa valve range, never the 1.0MPa cylinder body rating. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. For this 125mm stroke, side-load guides are not mandatory but ensure alignment to prevent seal wear.
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 SAUF80X125-08B FAQ
It provides 2513N push and 2268N pull at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec) running on DC24V. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly at 0.15-0.8MPa.
No, the built-in valve only routes air and is not a lock; the piston will drift on air loss, so add an external rod lock for holding. Additionally, this specific SKU lacks a magnet and cannot accept a position sensor.
