Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X80-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X80-08B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 80mm 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 SAUF63X80-08B
The AirTAC SAUF63X80-08B 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 makes it shorter than an ISO 15552 unit of the same bore. It features a 3/8" cylinder port, an M16x1.5 rod thread, and 21mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers a 1559 N push at 0.5 MPa. The integrated 4M310-08 valve has a 1/4" port, Cv 1.4 flow, and cycles up to 4 times per second. The DC24V terminal coil offers IP65 protection. For sizing, a safe working load is roughly 935 N, translating to a vertical lift capacity of about 79 kg with a 2:1 margin. Note this SKU lacks a magnet and cannot accept sensors.

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 SAUF63X80-08B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving manifold space.
Inline Divert Gate
Perfect for a conveyor divert gate that needs a self-contained actuator without running extra tubing back to a central control panel.
Package Stopper Arm
Suits a logistics line stopper arm, using the built-in valve to cycle up to 4 times per second for high throughput sorting.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X80-08B the Right Choice?
Size by comparing neighbouring bores: the 50mm bore offers 982 N push at 0.5 MPa, while the 80mm bore provides 2513 N. This 63mm unit outputs 1559 N push and 1402 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa assembled valve range, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry matches your supply. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Because this SKU has no magnet, it cannot take a sensor. The valve routes air and does not lock the load; add an external rod lock or pilot-operated check valve for holding. Since the 80mm stroke is under 300mm, side-load guides are less critical but still advised for rigid mounting.
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 SAUF63X80-08B FAQ
It delivers 1559 N push and 1402 N pull at 0.5 MPa, using a built-in 4M310-08 valve (1/4" port, Cv 1.4). The DC24V terminal coil operates at 0.15-0.8 MPa. Although the cylinder body rates to 1.0 MPa, the assembled unit must stay within the 0.15-0.8 MPa valve window.
Yes. The default action retracts the rod upon energising, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design means no remote valve is needed, though the valve only routes air and is not a load lock.
