Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X75-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X75-08A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 75mm 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 SAUF63X75-08A
The SAUF63X75-08A is an AirTAC double-acting profile cylinder with a built-in 4M310 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 63mm bore has a 3/8" air port, a 20mm rod, and M16x1.5 rod thread. Its extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore.
Size force within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it pushes 1559N and pulls 1402N. The safe working load is about 935N, allowing a vertical lift of roughly 79kg with a 2:1 margin. The 4M310-08 valve has a 1/4" port, Cv 1.4, and runs up to 4 cycles/s. This AC220V terminal entry coil is IP65 rated. Since this SKU lacks the S suffix, it cannot take a magnetic switch.

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 SAUF63X75-08A Is Used
Decentralized Clamping
Ideal for large machining cells where each clamping station switches itself via one AC220V signal, saving manifold space and tubing runs.
Inline Diverters
Perfect for conveyor routing gates that need independent 4M310 valve control at 4 cycles/s without routing air back to a central island.
Package Stops
Suits localized package stopping on sorting lines, using the 1559N push force at 0.5MPa to halt items cleanly.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X75-08A the Right Choice?
When sizing, compare both ways: the 50mm bore neighbor pushes 982N at 0.5MPa, while the 80mm bore reaches 2513N. This 63mm bore delivers 1559N push at 0.5MPa. Confirm the AC220V terminal entry and PT thread meet your control specs. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always operate within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For strokes over 300mm, use a guide to prevent side-load 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 SAUF63X75-08A FAQ
It pushes 1559N and pulls 1402N at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/s). The coil is AC220V with terminal entry. Size force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
No. The built-in valve routes air but is not a lock. If air is lost, the piston drifts and the 21mm cushion only decelerates near stroke end. For vertical load holding, add an external rod lock or pilot-operated check valve.
