Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X175-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X175-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 175mm 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 SAUF100X175-08A
The SAUF100X175-08A 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 directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. It features a 100mm bore, 175mm stroke, 1/2" cylinder port, M20x1.5 rod thread, and 29mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers a push force of 3927 N at 0.5 MPa and 6282 N at 0.8 MPa. The integrated valve has a 1/4" port, Cv 1.4, and handles up to 4 cycles/sec. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 2356 N, allowing a vertical lift of about 200 kg with a 2:1 margin. This SKU lacks the S magnet and cannot take a sensor.

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 SAUF100X175-08A Is Used
Machine Tool Clamping
Decentralized clamping on a large machining center. The built-in 4M310 valve switches the 100mm bore directly from one AC220V signal, eliminating long tube runs from a central manifold.
Heavy Divertor Gate
Actuating a heavy diverter on a packaging line. The 1/4" valve port and Cv 1.4 flow provide rapid response, while the compact profile saves space along the conveyor frame.
Pallet Stopper Arm
Deploying a stopper arm in a pallet handling cell. One coil signal extends or retracts the rod, saving a manifold slot and simplifying installation in tight warehouse automation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X175-08A the Right Choice?
Size force between 0.15-0.8 MPa: this 100mm bore pushes 3927 N at 0.5 MPa, while the 80mm neighbor pushes 2513 N. Confirm the AC220V terminal coil and PT threads match your supply. Default action retracts the rod when energized, but repositioning the valve extends it instead. The 4M310 valve routes air but does not lock the piston; add an external rod lock or pilot-operated check valve to hold loads. Since stroke is under 300mm, side-load guides are less critical but still advised for rigid mounting.
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 SAUF100X175-08A FAQ
It pushes 3927 N at 0.5 MPa and 6282 N at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec). The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window. The coil is AC220V with a terminal entry.
No. The 4M310 valve routes air but is not a lock; the piston drifts on air loss and the 29mm cushion only decelerates near stroke end. Add an external rod lock for holding. Also, this specific SKU lacks the S magnet, so it cannot take a magnetic switch.
