Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X150-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X150-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 150mm 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 SAUF80X150-08B
The SAUF80X150-08B is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot in decentralized setups. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. It features a 3/8 inch cylinder port, an M20x1.5 rod thread, and adjustable 28 mm cushions.
Operating within the valve's 0.15-0.8 MPa range, this 80 mm bore generates 2513 N push force at 0.5 MPa. The integrated valve provides a 1.4 Cv flow at 1/4 inch, cycling up to 4 times 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 the S suffix, so it cannot accept a magnetic 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 SAUF80X150-08B Is Used
Divert Gate Actuation
Drives a routing flap on a parcel line directly from one coil signal, removing the need to trace tubing back to a central manifold.
Pallet Stopper Control
Raises and lowers a stop block at a packing cell using the integrated 4M310-08 valve, cutting installation time.
Press Ejection
Ejects formed parts from a press with a self-contained actuator that simplifies machine wiring and maintenance access.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X150-08B the Right Choice?
When sizing, compare this 80 mm bore (2513 N push at 0.5 MPa) against the 63 mm bore (1559 N) or the 100 mm bore (3927 N) to match your load within the 0.15-0.8 MPa window. Verify the DC24V terminal entry and PT threads meet your electrical and plumbing needs. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. For this 150 mm stroke, side-load is minimal, but always guide the rod to prevent binding.
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 SAUF80X150-08B FAQ
It generates 2513 N push and 2268 N pull at 0.5 MPa. The built-in valve is a 4M310-08 with a 1.4 Cv and 1/4 inch port, running on DC24V. You must size the force within the valve's 0.15-0.8 MPa operating range, even though the cylinder body rates to 1.0 MPa.
By default the rod retracts when the coil is energized, but you can reposition the valve to extend on signal. The valve routes air and is not a lock; the piston drifts on air loss, so install an external rod lock or pilot-operated check valve to hold a load.
