Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450-08A 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 SAUF63X450-08A
The SAUF63X450-08A 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, saving tubing and a manifold slot in decentralized setups. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It uses a 3/8" cylinder port and an M16x1.5 rod thread.
This 63mm bore delivers 1559N push and 1402N pull at 0.5MPa. The safe working load is about 935N, allowing a vertical lift of roughly 79kg with a 2:1 margin. The integrated valve has a 1/4" port, Cv 1.4, and runs up to 4 cycles/s. The coil is AC220V with terminal entry. Because there is no -S suffix, this SKU cannot take a magnetic switch. Size force within the 0.15-0.8MPa valve window, not the 1.0MPa cylinder body rating.

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 SAUF63X450-08A Is Used
Transfer Gate Diversion
Drives a decentralized lane diverter on a conveyor line using a single AC220V signal, eliminating long tube runs back to a central manifold.
Pallet Stopper Arm
Acts as an independent pallet stop in a high-density storage zone, using the built-in 4M310 valve to cycle up to 4 times per second.
Clamp Station Actuation
Provides 1559N of clamping force at 0.5MPa on a machining cell, saving manifold space by mounting the valve directly on the cylinder cap.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450-08A the Right Choice?
Size this 63mm bore against its neighbours: a 50mm bore gives 982N push while an 80mm bore gives 2513N at 0.5MPa. This model provides 1559N push at 0.5MPa. Confirm the AC220V terminal entry and PT threads match your control panel. The rod retracts when the coil is energised; reposition the valve to extend on signal. The built-in valve routes air but does not lock the piston, so add an external rod lock or pilot-operated check valve to hold a load. For the 450mm 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 SAUF63X450-08A FAQ
It delivers 1559N push and 1402N pull at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 4 cycles/s max) running on AC220V. The cylinder body rates to 1.0MPa, but you must size force within the 0.15-0.8MPa operating window of the assembled valve.
Yes, the default action retracts the rod on signal, but you can reposition the valve to extend when energised. The valve only routes air; it is not a load lock. If air is lost, the piston drifts, so install an external rod lock or pilot-operated check valve for load holding.
