Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X175S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X175S-08B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 175mm 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 SAUF63X175S-08B
The AirTAC SAUF63X175S-08B is a double-acting profile cylinder with a built-in 4M310-08 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 63mm bore delivers a 1559N push at 0.5MPa within the 0.15-0.8MPa valve window. The cylinder body rates to 1.0MPa but the integrated valve limits the assembled unit to 0.8MPa.
This model switches at up to 4 cycles/sec with a Cv of 1.4. It uses a DC24V terminal entry coil rated IP65 and includes a piston magnet for sensors. The 3/8inch cylinder port and M16x1.5 rod thread are fixed by the bore. For sizing, the safe working load is roughly 935N (about 60% of the 0.5MPa push), and the vertical lift capacity is about 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 SAUF63X175S-08B Is Used
Modular Clamping Station
Decentralized clamping on a large machining line where the integrated valve eliminates long tube runs back to a central manifold.
Independent Divert Gate
One-signal actuation for a sorting diverter, saving a manifold slot and simplifying control wiring on the conveyor frame.
Vertical Lift Stopper
Compact profile stopper mechanism lifting loads up to 79kg, using the built-in magnet for position confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X175S-08B the Right Choice?
When sizing, compare neighbouring bores: the 50mm bore offers a 982N push while the 80mm bore provides 2513N at 0.5MPa. This 63mm bore gives 1559N push and 1402N pull. Confirm the DC24V terminal entry and PT thread meet your electrical specs. The rod retracts when the coil is energised but can be reconfigured to extend by repositioning the valve. Always size force within the 0.15-0.8MPa valve range. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 175mm stroke, side-load is minimal, but ensure adequate guidance for longer strokes.
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 SAUF63X175S-08B FAQ
It delivers a 1559N push and 1402N pull at 0.5MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4inch port, Cv 1.4, and runs on DC24V. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the 0.15-0.8MPa valve window.
By default the rod retracts when the coil is energised, but you can reconfigure it to extend by repositioning the valve. The valve only routes air and is not a load lock; on air loss the piston drifts. Use an external rod lock or pilot-operated check valve for load holding.
