Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X225-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X225-08A is a genuine double-acting profile-type cylinder with a Ø63mm 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 SAUF63X225-08A
The SAUF63X225-08A is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One AC220V 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 63mm bore has a 3/8" air port, an M16x1.5 rod thread, and 21mm adjustable cushions.
Size force strictly within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it delivers 1559N push and 1402N pull. This yields a computed safe working load of about 935N, or a 79kg vertical lift with a 2:1 margin. The 1/4" valve port gives 25 mm2 flow (Cv 1.4) at up to 4 cycles per second. Since this SKU lacks the S suffix, it cannot take 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 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 SAUF63X225-08A Is Used
Diverter Gate Actuation
Drives a routing flap on a packaging line directly from one coil signal, removing the need to run tubing back to a central valve manifold.
Decentralized Pallet Stop
Mounts independently on a conveyor frame to raise and lower a pallet stop, using the integrated 4M310-08 valve for fast local response.
Machine Tool Guard
Opens and closes a heavy access door on a machining center, saving manifold space while providing 1559N push force at 0.5 MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X225-08A the Right Choice?
When sizing, compare both neighbours: the 50mm bore gives 982N push while the 80mm bore gives 2513N push at 0.5 MPa. This 63mm unit provides 1559N push, so confirm your load fits the 935N safe working guideline. Verify the AC220V terminal entry and PT thread meet your control spec. The default action retracts the rod when energised, but you can reconfigure it to extend-when-energised by repositioning the valve. Remember the assembled unit operates at 0.15-0.8 MPa, not the 1.0 MPa cylinder rating. The built-in valve routes air and is not a lock; if power or air drops, the piston drifts. Add an external rod lock or pilot-operated check valve for held loads. For this 225mm stroke, fit external guides 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 SAUF63X225-08A FAQ
It generates 1559N push and 1402N pull at 0.5 MPa, reaching 2494N push at 0.8 MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port, Cv 1.4, and runs on AC220V. You must size the force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
Yes, you can reconfigure the default retract action to extend-when-energised simply by repositioning the valve. The valve only routes air; it is not a load lock. If air or power is lost the piston will drift, so install an external rod lock or pilot-operated check valve if you need to hold a load.
