Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 300mm 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 SAUF80X300-08B
The SAUF80X300-08B 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, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. This 80mm bore uses a 3/8" cylinder port, a 1/4" valve port, and a 28mm adjustable cushion.
The integrated valve restricts the working pressure to a 0.15-0.8 MPa window, even though the cylinder body rates to 1.0 MPa. The 4M310-08 valve provides 25 mm2 flow (Cv 1.4) and handles up to 4 cycles per second. At 0.5 MPa it pushes 2513 N and pulls 2268 N. For sizing, the safe working load is roughly 1508 N, and it can vertically lift about 128 kg with a 2:1 margin. The DC24V coil uses 3.0 W, features IP65 protection, and responds in 0.05 s or less.

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 SAUF80X300-08B Is Used
Conveyor Diverter Gate
Uses the built-in valve to switch the 300mm stroke diverter locally, eliminating long tube runs back to a central manifold on the production line.
Pallet Stopper Arm
Deploys a heavy stop arm directly at the pallet station. The 80mm bore provides 2513 N push at 0.5 MPa to halt moving loads without needing a remote valve.
Machine Tool Clamp
Clamps large castings inside a machining center. The 4M310-08 valve handles 4 cycles per second, providing rapid actuation right at the clamp point.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300-08B the Right Choice?
Size force between the 0.15-0.8 MPa valve limits: this 80mm bore yields 2513 N push at 0.5 MPa, while the neighboring 63mm bore yields 1559 N. Confirm the DC24V terminal entry and PT thread match your control scheme. The rod retracts when the coil is energized, but you can reposition the valve to extend on energization. Because this SKU lacks a magnet, it cannot take a magnetic switch. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For this 300mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF80X300-08B FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa. The built-in valve is a 4M310-08 with 1/4" port and Cv 1.4. The DC24V coil operates at 3.0 W. You must size force within the valve's 0.15-0.8 MPa working range, not the 1.0 MPa cylinder body rating.
By default the rod retracts when the coil is energized, but you can reposition the valve to extend on energization. The valve only routes air; it is not a load lock. The piston will drift on air loss, so install an external rod lock or pilot-operated check valve for load holding.
