Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350S-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 350mm 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 SAUF80X350S-08B
The SAUF80X350S-08B is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One coil signal drives the actuator, saving tubing and a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. This 80mm bore pushes 2513N and pulls 2268N at 0.5MPa. It includes a piston magnet for switches. The cylinder body rates to 1.0MPa, but you must size force within the valve's 0.15-0.8MPa window.
The integrated valve has a 1/4 inch port, 25mm2 flow (Cv 1.4), and cycles up to 4 times per second. The DC24V coil offers IP65 protection with a 0.05s response. The bore uses a 3/8 inch air port and PU tube Ø10xØ6.5. Based on the 0.5MPa push force, the safe working load is about 1508N, allowing a vertical lift of roughly 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 SAUF80X350S-08B Is Used
Sorting Diverter
Decentralized diverter gate on a high-speed conveyor. The built-in valve eliminates long tubing runs back to a central manifold, improving response time.
Pallet Stopper
Independent pallet stopping station in a warehouse line. One electrical signal actuates the 350mm stroke without needing a dedicated remote valve island.
Machine Guard Gate
Actuating a heavy access gate on a large machine. The 80mm bore provides high push force, and the integrated valve simplifies control wiring.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350S-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 model provides 2513N of push force. Confirm your coil is DC24V with terminal entry. The rod retracts when the coil is energized, but you can reposition the valve to extend on energization. Always operate within the 0.15-0.8MPa valve range, never the 1.0MPa cylinder body rating. The 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 350mm stroke, use external guides to prevent rod bending and side-load damage. Mounting uses AirTAC SC series accessories.
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 SAUF80X350S-08B FAQ
It delivers 2513N push and 2268N pull at 0.5MPa. The built-in valve is a 4M310-08 with a 1/4 inch port, Cv 1.4, and a DC24V coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window. The bore features a 3/8 inch air port.
No. The built-in valve routes air and is not a load lock. If air is lost, the piston drifts. For vertical load holding, you must add an external rod lock or a pilot-operated check valve. The default action retracts the rod when energized, but you can reposition the valve to extend on energization.
