Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X160S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X160S-08A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 160mm 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 SAUF63X160S-08A
The SAUF63X160S-08A is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote valves and saving a manifold slot. The 63mm bore delivers 1559N push and 1402N pull at 0.5MPa. The cylinder body rates to 1.0MPa, but you must size force within the integrated valve's 0.15-0.8MPa operating window.
The integrated valve provides 25mm2 flow (Cv 1.4) via a 1/4" port, cycling up to 4 times per second. The bore's air port is 3/8" with a PT thread. This unit includes a piston magnet for position sensing. Based on the 0.5MPa push force, the computed safe working load is roughly 935N (about 60% of capacity), translating to a vertical lift capacity of approximately 79kg 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 SAUF63X160S-08A Is Used
Machine Tool Clamping
Decentralized clamping on a machining line where the built-in valve keeps response time under 0.05s without long tube runs from a central manifold.
Package Diverting
One-signal actuation for diverting arms on a conveyor, saving manifold space and simplifying installation across multiple zones.
Vertical Lift Gates
Lifting lightweight access gates in automated storage systems, utilizing the 79kg vertical lift capacity within the 0.15-0.8MPa window.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X160S-08A the Right Choice?
Size this 63mm bore against the neighbouring 50mm (982N push) and 80mm (2513N push) options at 0.5MPa. The 160mm stroke is standard and above the 75mm SAUF minimum for this bore. Confirm the AC220V terminal entry and PT threads suit your setup. The default action retracts the rod when energised; reposition the valve to extend on signal. The valve routes air but does not lock the piston, so add an external rod lock or pilot-operated check valve for held loads. For strokes over 300mm, use side-load guides to prevent rod damage.
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 SAUF63X160S-08A FAQ
It pushes 1559N and pulls 1402N at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4) running on AC220V. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within the valve's 0.15-0.8MPa range.
By default, the rod retracts when the coil receives the AC220V signal. You can reconfigure it to extend-when-energised simply by repositioning the valve on the cap. The valve only routes air, so it will not hold a load without air pressure.
