Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X75S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X75S-08A is a genuine double-acting profile-type cylinder with a Ø100mm 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 SAUF100X75S-08A
The SAUF100X75S-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. The 1/2" cylinder port and M20x1.5 rod thread handle high flow.
Operating in the 0.15-0.8 MPa valve window, it delivers 3927 N push at 0.5 MPa. The 4M310-08 valve has a 1/4" port, Cv 1.4, and runs up to 4 cycles/sec. The AC220V terminal coil is IP65 rated. With a 75 mm stroke, the 29 mm cushions decelerate the load. Safe working load is roughly 2356 N, allowing a 200 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAUF100X75S-08A Is Used
Press Clamping
Decentralized clamping in a large press line. The built-in valve provides immediate local actuation without routing long control lines back to a central manifold.
Heavy Diverter
Diverting heavy pallets on a conveyor. One coil signal per actuator simplifies control logic and reduces tubing complexity across the wide machine frame.
Pallet Lift Station
Lifting loaded pallets at a packing station. The 100 mm bore provides the necessary force, while the integrated valve minimizes installation time.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X75S-08A the Right Choice?
Size by comparing the 100 mm bore (3927 N push @0.5 MPa) against the 80 mm neighbor (2513 N). Confirm the AC220V terminal entry and PT threads. Default action retracts the rod when energized; reposition the valve to extend on signal. Size force strictly within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The valve routes air but does not lock; add an external rod lock or pilot-operated check valve to hold loads. The S suffix provides a piston magnet for sensors. For strokes over 300 mm, guide the load to prevent side-load wear.
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 SAUF100X75S-08A FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4) running on AC220V. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
By default the rod retracts when the coil is energized; you can reposition the valve to extend on signal. The 5/2 valve routes air but does not lock the piston. For load holding on air loss, install an external rod lock or pilot-operated check valve.
