Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X500S-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X500S-10B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 500mm stroke and a built-in 4M310-10 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 SAUF63X500S-10B
The SAUF63X500S-10B is a double-acting profile cylinder with a built-in AirTAC 4M310 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. The cylinder port is 3/8", while the valve port is 3/8" with a flow of 30 mm2 (Cv 1.68) and a max frequency of 4 cycles/s.
The body rates to 1.0 MPa, but the integrated valve limits the assembled working pressure to 0.15-0.8 MPa. At 0.5 MPa it delivers 1559 N push and 1402 N pull. The safe working load is roughly 935 N (about 60% of the 0.5 MPa push), and it can vertically lift around 79 kg with a 2:1 margin. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.

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 SAUF63X500S-10B Is Used
Sorting Diverter
Mounts directly on a conveyor diverter arm. The built-in 4M310 valve handles rapid local switching without long tubing runs back to a central manifold.
Vertical Lift Gate
Lifts a 79 kg pallet gate using the 0.5 MPa push force. The compact profile saves space, and the 4M310 valve ensures immediate local response.
Indexing Clamp
Drives a 500 mm clamping stroke on an indexing table. The DC24V coil provides IP65 switching, and the adjustable cushions decelerate the load at stroke end.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X500S-10B the Right Choice?
Size this 63 mm bore against the 50 mm (982 N push @0.5 MPa) and 80 mm (2513 N push @0.5 MPa) neighbors. Confirm the DC24V terminal entry and PT thread before ordering. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. The valve only routes air; it is not a load lock. For a held load, add an external rod lock or pilot-operated check valve. The 500 mm stroke exceeds 300 mm, so 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 SAUF63X500S-10B FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa. The built-in valve is a 4M310-10 with a 3/8" port, Cv 1.68, and 30 mm2 flow. The DC24V coil runs at 3.0 W. The cylinder body rates to 1.0 MPa, but the assembled unit must operate within the 0.15-0.8 MPa valve window.
No. The built-in 4M310 valve routes air but does not lock the piston. On air loss the piston drifts. The default action retracts when energized, but you can reposition the valve to extend on signal. For vertical load holding, install an external rod lock or pilot-operated check valve.
