Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X225-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X225-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 225mm 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 SAUF100X225-08A
The SAUF100X225-08A is a double-acting profile-type 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 unit of the same bore. It features a 1/2" cylinder port, an M20x1.5 rod thread, and 29mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers a 3927 N push force at 0.5 MPa. The integrated valve provides a 1.4 Cv flow at 1/4" and handles up to 4 cycles per second. This AC220V terminal-entry coil offers IP65 protection. For sizing, the safe working load is roughly 2356 N, capable of a 200 kg vertical lift with a 2:1 margin. Note this SKU lacks the S magnet suffix and cannot accept a magnetic switch.

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 SAUF100X225-08A Is Used
Heavy Stamp Feeders
Decentralized press feeding where the 100mm bore pushes heavy blanks using one local AC220V signal, skipping a central valve manifold.
Pallet Diverters
Directs loaded pallets on a line. The built-in 4M310 valve handles the 4M310-08 flow without extra tubing runs to a remote island.
Vertical Lift Gates
Raises material handling gates. The 3927 N push at 0.5 MPa provides a 200 kg vertical lift capacity with a 2:1 safety margin.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X225-08A the Right Choice?
Size force between the 63mm bore (1559 N push at 0.5 MPa) and this 100mm bore (3927 N push), staying inside the 0.15-0.8 MPa valve limit rather than the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry meets your control voltage. The rod retracts when energised by default but can be reconfigured to extend by repositioning the valve. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold a load. For this 225mm stroke, guide the mechanism to manage side loads.
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 SAUF100X225-08A FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1.4 Cv flow and a 1/4" port. The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0 MPa, you must size force within the 0.15-0.8 MPa valve operating window.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The valve only routes air and is not a lock. The piston drifts on air loss, so install an external rod lock or pilot-operated check valve for load holding.
