Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350-10A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 350mm 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 SAUF80X350-10A
The SAUF80X350-10A 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 makes it shorter than an ISO 15552 cylinder of the same bore. This bore features a 3/8" air port, an M20x1.5 rod thread, and 28mm adjustable cushions.
The integrated 4M310-10 valve has a 3/8" port, Cv 1.68 flow, and cycles up to 4 times per second. The AC220V terminal entry coil is IP65 rated. The cylinder body rates to 1.0 MPa, but the valve limits operation to 0.15-0.8 MPa. At 0.5 MPa it pushes 2513 N and pulls 2268 N. A computed buyer insight gives a safe working load of roughly 1508 N, ideal for a vertical lift of about 128 kg 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 SAUF80X350-10A Is Used
Decentralized Diverters
Drives individual lane diverters directly at the conveyor, using one AC220V signal per actuator to eliminate long tube runs back to a central manifold.
Packaging Machine Stops
Provides robust 80mm bore stopping power for heavy cartons, cycling up to 4 times per second without needing a remote valve island.
Pallet Handling Gates
Actuates heavy pallet routing gates with a safe 1508 N working load, simplifying installation by integrating the 4M310 valve directly on the cap.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350-10A the Right Choice?
Size force within the 0.15-0.8 MPa valve window: this 80mm bore pushes 2513 N at 0.5 MPa, sitting between the 63mm bore (1559 N) and the 100mm bore (3927 N). Confirm the AC220V terminal entry coil meets your supply. Default action retracts the rod when energised; reposition the valve to extend on signal. The 350mm stroke requires external guides to prevent rod bending under side loads. This SKU lacks a magnet and cannot take a sensor. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads on air loss.
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 SAUF80X350-10A FAQ
It delivers 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). 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.
No, the built-in 5/2 valve only routes air and is not a lock. The rod retracts by default when energised but drifts on air loss. For vertical load holding, install an external rod lock or a pilot-operated check valve.
