Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X150S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X150S-08A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 150mm 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 SAUF63X150S-08A
The SAUF63X150S-08A is a double-acting profile cylinder with a built-in AirTAC 4M310 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It features a 3/8 inch cylinder port, an M16x1.5 rod thread, and adjustable 21 mm cushions.
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 1559 N and pulls 1402 N, yielding a safe working load of about 935 N or a 79 kg vertical lift with a 2:1 margin. The integrated valve flows 25 mm2 (Cv 1.4) via a 1/4 inch port, cycling up to 4 times per second. This AC220V terminal-entry coil is IP65 rated, and the S suffix provides a piston magnet for CMSG/DMSG/EMSG sensors.

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 SAUF63X150S-08A Is Used
Diverter Gate Actuation
Drives a routing flap on a sorting line directly from one coil signal, removing the need to run long tubing back to a central manifold.
Decentralized Pallet Stop
Raises and lowers a pallet stop in a packaging cell, using the integrated 4M310 valve to simplify installation and save manifold space.
Independent Clamp Station
Powers a clamping arm on a machining fixture where local switching is faster and more reliable than remote valve control.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X150S-08A the Right Choice?
When sizing, compare both ways: a 50 mm bore neighbor offers 982 N push at 0.5 MPa, while an 80 mm bore provides 2513 N. This 63 mm bore hits 1559 N push at 0.5 MPa. Confirm the AC220V terminal entry and PT threads meet your specs. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size within the 0.15-0.8 MPa valve operating range. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 150 mm stroke, ensure adequate side-load guidance.
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 SAUF63X150S-08A FAQ
It generates 1559 N push and 1402 N pull at 0.5 MPa. The built-in 4M310-08 valve has a 1/4 inch port, Cv 1.4, and cycles up to 4 times per second. The AC220V coil runs on terminal entry. You must size force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
Yes, the default action retracts the rod on signal, but you can reposition the valve to extend when energized. The valve only routes air; it is not a load lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve for load holding.
