Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X75-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X75-08B 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 SAUF63X75-08B
The AirTAC SAUF63X75-08B is a 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 extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It features a 63mm bore, 75mm stroke, and a 3/8" cylinder port.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers 1559 N push and 1402 N pull at 0.5 MPa. The integrated 4M310-08 valve has a 1/4" port, Cv 1.4, and cycles up to 4 times per second. The DC24V terminal coil is IP65 rated. For sizing, the safe working load is roughly 935 N, allowing a vertical lift of about 79 kg 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 SAUF63X75-08B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate on a long conveyor line. The integrated 4M310 valve switches the 63mm bore locally, removing the need to run long tubing back to a central manifold.
Independent Machine Clamp
Ideal for a standalone clamping station on a large machine bed. One DC24V coil signal actuates the clamp, saving manifold space and simplifying pneumatic plumbing.
Zone Stopper Gate
Controls a zone stopper in an automated warehouse. The built-in valve provides rapid local actuation at up to 4 cycles per second without remote valve plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X75-08B the Right Choice?
When sizing, compare neighbouring bores: the 50mm bore offers 982 N push at 0.5 MPa, while the 80mm bore provides 2513 N. This 63mm bore fits applications needing 1559 N push. Confirm the DC24V terminal entry and PT threads meet your electrical specs. The cylinder body rates to 1.0 MPa, but you must size force within the built-in valve's 0.15-0.8 MPa range. By default the rod retracts when energised; repositioning the valve changes it to extend-when-energised. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold loads. Because this SKU lacks a magnet, it cannot take a magnetic switch. For strokes over 300mm, use side-load guides.
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 SAUF63X75-08B FAQ
It generates 1559 N push and 1402 N pull at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/s). The coil is DC24V with terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
By default, the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This self-switching design means one coil signal drives the cylinder without needing a separate remote valve.
