Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450-10A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 450mm stroke and a built-in 4M310-10 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 SAUF63X450-10A
The AirTAC SAUF63X450-10A is a double-acting profile cylinder with a built-in 4M310 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. It has a 63 mm bore, 450 mm stroke, and a 3/8" air port.
Operating within the 0.15-0.8 MPa valve window, it delivers 1559 N push force at 0.5 MPa. The integrated 4M310-10 valve has a 3/8" port, Cv 1.68 flow, and handles 4 cycles/sec. The AC220V terminal entry coil is IP65 rated. Based on the 0.5 MPa push force, the safe working load is approximately 935 N, yielding a vertical lift capacity of about 79 kg with a 2:1 margin.

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 SAUF63X450-10A Is Used
Inline Divert Gate
Decentralized diverter on a conveyor belt driven by one AC220V signal without long tubing runs to a central manifold.
Pallet Stopper Arm
Independent stopper arm at a packaging station using the integrated 4M310 valve to save manifold space.
Machine Tool Guard
Access door actuation on a machine tool where local switching simplifies wiring and speeds up the 4 cycles/sec motion.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450-10A the Right Choice?
Size by comparing neighbor bores: the 50 mm bore gives 982 N push at 0.5 MPa, while the 80 mm bore gives 2513 N. This 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa. Size all forces within the 0.15-0.8 MPa valve operating range, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry coil meets your supply. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. This SKU lacks the S magnet and cannot accept a sensor. For the 450 mm stroke, use external guides to prevent rod bending and side loads. The valve routes air; it is not a 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 SAUF63X450-10A FAQ
It delivers 1559 N push and 1402 N pull at 0.5 MPa, reaching 2494 N push at 0.8 MPa. The built-in valve is a 4M310-10 with a 3/8" port, Cv 1.68 flow, and 4 cycles/sec max. The AC220V coil uses terminal entry. You must size forces within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. The built-in valve only routes air; it is not a load lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve for load holding.
