Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450-10A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 450mm 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 SAUF80X450-10A
The AirTAC SAUF80X450-10A is a double-acting profile cylinder with a built-in 4M310-10 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than a standard ISO 15552 unit of the same bore. It features a 3/8" valve port, a 3/8" cylinder port, and a 25 mm piston rod with an M20x1.5 thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 2513 N push force at 0.5 MPa. The valve flows 30 mm2 (Cv 1.68) at up to 4 cycles per second. For sizing, the safe working load is roughly 1508 N, and it can vertically lift about 128 kg with a 2:1 margin. Note 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 SAUF80X450-10A Is Used
Machine Tool Clamping
Decentralized clamping on a large machining center. The integrated valve switches the 450 mm stroke locally, saving tubing runs back to a central manifold.
Transfer Line Diversion
Actuating a diverter gate on a packaging line. One AC220V signal drives the 80 mm bore directly, simplifying control wiring and reducing installation time.
Pallet Handling Stops
Raising and lowering heavy pallet stops. The built-in 4M310 valve handles the required flow instantly without needing a remote valve island.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450-10A the Right Choice?
Size by checking both neighboring bores: the 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. This 80 mm bore provides 2513 N. Confirm your coil is AC220V with terminal entry before ordering. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Size all forces within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Because the 450 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side loads. The valve only routes air; add an external rod lock or pilot-operated check valve to hold a load safely.
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 SAUF80X450-10A FAQ
It pushes 2513 N and pulls 2268 N 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, 30 mm2 flow, max 4 cycles/sec). The coil is AC220V with terminal entry. You must size forces within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
By default the rod retracts when the coil is energized, but you can reconfigure it to extend by repositioning the valve. The valve only routes air and is not a load lock. The piston will drift on air loss, so you must add an external rod lock or pilot-operated check valve for vertical holding.
