Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 450mm 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 SAUF80X450-08A
The SAUF80X450-08A 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, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 3/8" cylinder port, an M20x1.5 rod thread, and 28mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers 2513 N push force at 0.5 MPa. The 1/4" valve port flows 25 mm2 (Cv 1.4) at up to 4 cycles per second. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 1508 N, and vertical lift capacity is about 128 kg 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 SAUF80X450-08A Is Used
Decentralized Sorting Diverter
Mounts directly on the conveyor frame to push packages. The integrated valve eliminates long tube runs back to a central manifold, speeding up the 4 cycles per second sorting action.
Palletizing Stop Gate
Acts as a heavy-duty stop on a pallet line. One AC220V signal drives the 2513 N push force, simplifying wiring and freeing up valve island space for other actuators.
Machine Tool Clamp
Clamps large castings securely. The built-in 4M310 valve handles the 0.15-0.8 MPa pressure window perfectly, while the 28mm cushions decelerate the 450mm stroke smoothly.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450-08A the Right Choice?
Size against the 63mm and 100mm bores: the 63mm bore yields 1559 N push while the 100mm bore yields 3927 N at 0.5 MPa. This 80mm bore provides 2513 N push and 2268 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve operating range, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry coil matches your supply. The rod retracts when energised by default, but you can reposition the valve to extend on signal. For the 450mm stroke, use an external guide to prevent rod bending and side-load wear. Because this SKU lacks the S suffix, it cannot take a magnetic switch.
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 SAUF80X450-08A FAQ
It generates 2513 N push and 2268 N pull at 0.5 MPa, reaching 4021 N push at 0.8 MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port, Cv 1.4, and 25 mm2 flow. The AC220V terminal coil is IP65 rated. You must size the force within the 0.15-0.8 MPa valve operating range, not the 1.0 MPa cylinder body limit.
No, the built-in valve only routes air and is not a load lock. If air is lost, the piston drifts and the 28mm cushion only decelerates near stroke end. For a held vertical load, install an external rod lock or a pilot-operated check valve. Also, the rod retracts when energised by default but can be reconfigured to extend by repositioning the valve.
