Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X1000S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X1000S-08B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 1000mm 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 SAUF63X1000S-08B
The SAUF63X1000S-08B is a double-acting profile-type cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot in large machines. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1000 mm stroke, a 3/8" cylinder port, and an M16x1.5 rod thread.
Operating within the valve's 0.15-0.8 MPa window, this bore delivers a 1559 N push force at 0.5 MPa. The integrated valve flows 25 mm2 (Cv 1.4) at a 1/4" port, cycling up to 4 times per second. The DC24V terminal coil offers IP65 protection. For sizing, the safe working load is roughly 935 N, and the vertical lift capacity is about 79 kg with a 2:1 margin. The S suffix denotes a piston magnet for position sensing.

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 SAUF63X1000S-08B Is Used
Decentralized Conveyor Divert
Uses the integrated 4M310-08 valve to actuate a 1000 mm divert gate directly at the station, eliminating long tubing runs back to a central manifold.
Vertical Package Lift
Lifts packages up to 79 kg with a 2:1 safety margin using the 63 mm bore, relying on the built-in magnet for precise position feedback.
Long-Stroke Material Push
Pushes workpieces along a 1000 mm stroke with 935 N safe working load, saving manifold space by switching locally via the DC24V coil.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X1000S-08B the Right Choice?
Size by checking both neighboring bores: the 50 mm bore yields 982 N push at 0.5 MPa, while the 80 mm bore provides 2513 N. This 63 mm bore outputs 1559 N push and 1402 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT threads match your supply. The rod retracts by default when energized, but you can reposition the valve to extend on signal. Because the 1000 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side-load wear. The valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve.
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 SAUF63X1000S-08B FAQ
It generates 1559 N push and 1402 N pull at 0.5 MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port and Cv 1.4. The DC24V coil runs at 3.0 W. You must size operations within the valve's 0.15-0.8 MPa working range, even though the cylinder body rates to 1.0 MPa.
No, the built-in valve only routes air and is not a load lock. If air is lost, the piston will drift. To hold a vertical load securely, you must install an external rod lock or a pilot-operated check valve.
