Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450-08B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 450mm 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 SAUF63X450-08B
The SAUF63X450-08B 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, 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 SKU has no magnet, so it cannot take a magnetic switch.
It operates on DC24V via terminal entry with PT threads. The 3/8" cylinder port and M16x1.5 rod end handle a 1559 N push force at 0.5 MPa. A computed buyer insight: safe working load is roughly 935 N, allowing a 79 kg vertical lift with a 2:1 margin. The 4M310-08 valve has a 1/4" port, Cv 1.4, and runs at 4 cycles/s. Size within the 0.15-0.8 MPa valve window, as the 1.0 MPa cylinder body rating exceeds the assembled valve limit.

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 SAUF63X450-08B Is Used
Divert Gate Actuation
Drives a diverting gate on a packaging line. The integrated valve means only one wire connection per lane, cutting installation time across multiple decentralized diverters.
Vertical Carton Lift
Lifts cartons between conveyor levels. The 63 mm bore handles the 79 kg vertical lift capacity safely, while the built-in valve removes the need for nearby manifold plumbing.
Machine Tool Clamping
Clamps workpieces at independent machining stations. One coil signal per clamp simplifies control architecture and eliminates long tubing runs back to a central valve island.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450-08B 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, making it ideal for mid-range tasks. Confirm the DC24V coil and terminal entry suit your control system. Default action retracts the rod when energized, but repositioning the valve extends it on signal. Keep operating pressure between 0.15-0.8 MPa. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads safely. For the 450 mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF63X450-08B 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 4M310-08 valve has a 1/4" port, Cv 1.4, and a DC24V coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
No, the 5/2 valve only routes air and is not a load lock; the piston drifts on air loss. Add an external rod lock or pilot-operated check valve for holding. Additionally, this specific SKU lacks a magnet (-S), so it cannot accept a magnetic switch.
