Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X150-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X150-08B 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 SAUF63X150-08B
The SAUF63X150-08B is a double-acting profile-type 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 in decentralized installations. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 63mm bore, 150mm stroke, and a 3/8" cylinder port.
Operating within the valve's 0.15-0.8 MPa window, it delivers a 1559 N push force at 0.5 MPa. The integrated 4M310-08 valve has a 1/4" port, Cv 1.4, and handles up to 4 cycles/sec. The DC24V coil uses terminal entry and is IP65 rated. For sizing, the safe working load is roughly 935 N (about 60% of the 0.5 MPa push), allowing a 79 kg vertical lift with a 2:1 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)
| 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 SAUF63X150-08B Is Used
Diverter Gate Actuation
Drives a decentralized sorting flap directly at the conveyor lane, using the built-in valve to switch instantly without routing tubing back to a central manifold.
Pallet Stopper Control
Raises and lowers a pallet stop in a packaging cell, saving manifold space while providing 1559 N of push force at 0.5 MPa.
Clamp Station Operation
Actuates a localized clamping fixture independently, relying on the 4M310 valve's 4 cycles/sec speed for responsive machine sequencing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X150-08B the Right Choice?
Size by comparing neighboring bores: the 50mm bore pushes 982 N while the 80mm bore pushes 2513 N at 0.5 MPa. This 63mm bore provides 1559 N push and 1402 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve operating range, not the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT threads meet your electrical standards. The rod retracts when the coil is energized; reposition the valve to switch to extend-when-energised. Because this SKU lacks a magnet suffix (-S), it cannot accept a magnetic switch. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve for load holding. For this 150mm stroke, ensure 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 SAUF63X150-08B FAQ
It delivers 1559 N push and 1402 N pull at 0.5 MPa, reaching 2494 N push at 0.8 MPa. The built-in 4M310-08 valve has a 1/4" port, Cv 1.4, and runs on DC24V. You must size the force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
One coil signal shifts the integrated 5/2 valve, defaulting to retract-when-energised; reposition the valve to extend-when-energised. The valve only routes air—it is not a lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve for load holding.
