Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450-10B 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 SAUF63X450-10B
The SAUF63X450-10B is a double-acting profile cylinder with a built-in AirTAC 4M310-10 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 makes it shorter than an ISO 15552 cylinder of the same bore. This 63mm bore uses a 3/8 inch air port, a 20mm rod, and adjustable 21mm cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers a 1559 N push force at 0.5 MPa. This yields a computed safe working load of roughly 935 N, or a vertical lift capacity of about 79 kg with a 2:1 margin. The integrated valve provides a 30 mm2 flow (Cv 1.68) and switches up to 4 cycles per second. The DC24V terminal coil is IP65 rated. Since this SKU lacks the S suffix, it 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 (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 SAUF63X450-10B Is Used
Sorting Diverter
Decentralized package routing on a conveyor where the integrated valve eliminates long tubing runs back to a central manifold.
Machine Guard Gate
Single-signal actuation for an access door, using the 4M310-10 valve to switch the actuator directly at the mounting point.
Vertical Lift Stop
Material stopper on a vertical handling axis, driven by one coil signal to save manifold space in tight control cabinets.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450-10B the Right Choice?
Size by comparing neighbor bores: the 50mm bore pushes 982 N while the 80mm bore pushes 2513 N at 0.5 MPa. This 63mm bore provides 1559 N push and 1402 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal coil and PT thread suit your control system. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Because the 450mm stroke exceeds 300mm, add an external guide to prevent rod bending and side-load wear. The valve only routes air; it is not a lock, so fit an external rod lock or pilot-operated check valve to hold loads safely.
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 SAUF63X450-10B FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa, reaching 2494 N at 0.8 MPa. The built-in valve is a 4M310-10 with 3/8 inch port, Cv 1.68, and 30 mm2 flow. It uses a DC24V terminal coil. You must size force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the integrated valve. This self-switching design means one coil signal drives the cylinder without needing a separate remote valve.
