Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900S-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900S-10A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 900mm 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 SAUF63X900S-10A
The SAUF63X900S-10A is a double-acting profile cylinder with a built-in AirTAC 4M310-10 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 63mm bore uses a 3/8 inch air port, a 20mm rod with an M16x1.5 thread, and includes a piston magnet for CMSG/DMSG/EMSG switches. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore.
Operating strictly within the 0.15-0.8 MPa valve window, it delivers 1559N push and 1402N pull at 0.5 MPa. The integrated valve flows 30 mm2 (Cv 1.68) at up to 4 cycles per second. For sizing, the safe working load is roughly 935N (about 60% of the 0.5MPa push force), translating to a vertical lift capacity of approximately 79kg with a 2:1 safety 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)

|---|---|---|
| 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 SAUF63X900S-10A Is Used
Long-Stroke Diversion
Decentralized 900mm pusher on a conveyor line where routing a remote valve manifold would waste tubing and complicate maintenance.
Automated Assembly Press
Independent clamping station driven by a single AC220V signal, utilizing the 4M310-10 valve for rapid 4 cycle/sec actuation.
Vertical Lift Gate
Lifting a 79kg gate assembly using the integrated magnet for end-of-stroke confirmation without needing a separate manifold block.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900S-10A the Right Choice?
Size by comparing neighboring bores: the 50mm bore offers 982N push at 0.5MPa, while the 80mm provides 2513N. This 63mm unit outputs 1559N push and 1402N pull at 0.5MPa. Confirm the AC220V terminal entry and PT thread before ordering. The cylinder body rates to 1.0MPa, but you must size force within the 0.15-0.8MPa valve range. The rod retracts when energized but can be reconfigured to extend by repositioning the valve. Because the 900mm stroke exceeds 300mm, use external guides to prevent rod bending and side-load wear. The valve only routes air; it is not a load lock, so add an external rod lock or pilot-operated check valve to hold loads securely.
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 SAUF63X900S-10A FAQ
It delivers 1559N push and 1402N pull at 0.5MPa, reaching 2494N push at 0.8MPa. The built-in valve is a 4M310-10 (3/8 inch port, Cv 1.68, 30 mm2 flow) running on an AC220V terminal-entry coil. 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 energized, but you can reconfigure it to extend-when-energized simply by repositioning the valve. The 5/2 valve only routes air and is not a lock; on air loss the piston drifts and the cushion only decelerates near stroke end. For load holding, install an external rod lock or pilot-operated check valve.
