Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450S-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450S-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 SAUF80X450S-10A
The SAUF80X450S-10A is an extruded aluminum profile-type double-acting 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 80mm bore delivers 2513N push and 2268N pull at 0.5 MPa. It includes a piston magnet for position sensing.
The integrated valve has a 3/8 inch port, Cv 1.68 flow, and handles 4 cycles per second. The cylinder body rates to 1.0 MPa, but the valve limits operation to 0.15-0.8 MPa. Computed buyer insight: safe working load is roughly 1508N, and vertical lift capacity is about 128kg with a 2:1 margin. Terminal entry, AC220V coil, and PU tube Ø10xØ6.5 are standard.

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 SAUF80X450S-10A Is Used
Decentralized Conveyor Diverter
Mounts directly at the diverter station on a long conveyor line. One coil signal actuates the 450mm stroke without routing tubing back to a central manifold.
Independent Vertical Lift Gate
Ideal for a standalone warehouse lift gate. The built-in 4M310 valve handles the 80mm bore flow, saving manifold space while lifting loads up to 128kg.
Machine Guard Door Actuator
Drives a large machine guard door. The integrated valve simplifies installation, and the AC220V terminal entry connects directly to local machine wiring.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450S-10A the Right Choice?
Size by checking both neighboring bores: the 63mm bore yields 1559N push at 0.5 MPa, while the 100mm bore yields 3927N. This 80mm bore provides 2513N push at 0.5 MPa. Confirm the AC220V terminal entry and 3/8 inch valve port meet your specs. The cylinder body rates to 1.0 MPa, but the assembled unit operates strictly within the 0.15-0.8 MPa valve window. Default action retracts the rod when energized, but repositioning the valve extends it on signal. The 450mm stroke requires external guides to prevent rod bending under side loads. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the valve only routes air.
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 SAUF80X450S-10A FAQ
It generates 2513N push and 2268N pull at 0.5 MPa, reaching 4021N push at 0.8 MPa. The built-in valve is a 4M310-10 with a 3/8 inch port and Cv 1.68. The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit operates within the 0.15-0.8 MPa valve window.
By default, the rod retracts when the coil is energized. You can reconfigure it to extend when energized by repositioning the valve. The valve only routes air, so it is not a load lock. The piston drifts on air loss, so add an external rod lock or pilot-operated check valve to hold a load.
