Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X300-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X300-08B is a genuine double-acting profile-type cylinder with a Ø100mm 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 SAUF100X300-08B
The SAUF100X300-08B is a double-acting profile cylinder with a built-in AirTAC 4M310 5/2 solenoid valve on the cap. One coil signal drives the actuator, saving tubing and a manifold slot in decentralized setups. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. This 100mm bore uses a 1/2" port and delivers 3927N push at 0.5MPa.
The integrated valve offers 1/4" porting with a Cv of 1.4 and cycles up to 4 times per second. The DC24V coil features terminal entry, IP65 protection, and a 0.05s response. Size force within the 0.15-0.8MPa valve window. Based on the 3927N push at 0.5MPa, the safe working load is roughly 2356N, allowing a vertical lift of about 200kg 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAUF100X300-08B Is Used
Pallet Diversion Gate
Uses one coil signal to actuate a heavy diverter without running long tubing to a remote manifold.
Vertical Lift Station
Lifts 200kg loads using the 100mm bore thrust, keeping the valve integrated for a compact footprint.
Press Ejection System
Ejects parts at up to 4 cycles per second with the 4M310 valve, saving a manifold slot on the press.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X300-08B the Right Choice?
When sizing, compare neighbors: the 80mm bore yields 2513N push while the 100mm bore yields 3927N at 0.5MPa. This 300mm stroke requires external guides to prevent rod bending under side loads. Confirm the DC24V terminal entry and PT threads meet your specs. The cylinder body rates to 1.0MPa, but you must size force within the 0.15-0.8MPa valve range. Default action retracts the rod when energized; reposition the valve to extend instead. The valve routes air and is not a load lock. Add an external rod lock or pilot-operated check valve to hold loads on air loss.
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 SAUF100X300-08B FAQ
It pushes 3927N and pulls 3681N at 0.5MPa. The built-in 4M310-08 valve has a 1/4" port, Cv of 1.4, and runs on DC24V. Although the cylinder body rates to 1.0MPa, you must size force within the 0.15-0.8MPa valve window.
Yes. The default action retracts the rod when energized, but you can reposition the valve on the cap to make it extend instead. The valve simply routes air, so it is not a load lock and will not hold the load without air.
