Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X75S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X75S-08B 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-08B
The SAUF100X75S-08B is a double-acting profile cylinder with a built-in AirTAC 4M310-08 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 unit of the same bore. This 100mm bore features a 1/2" cylinder port, an M20x1.5 rod thread, and 29mm adjustable cushions. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
Operating on DC24V with terminal entry, the integrated valve has a 1/4" port, Cv 1.4 flow, and cycles up to 4 times per second. 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 3927 N and pulls 3681 N. A computed buyer insight: safe working load is roughly 2356 N (60% of the 0.5 MPa push), allowing a vertical lift of about 200 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 (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-08B Is Used
Heavy-Duty Press Stand
Decentralized pressing in a machining line. The built-in 4M310 valve delivers high flow directly to the 100mm bore without long tubing runs from a central manifold.
Pallet Diverter Gate
Independent actuator control on a conveyor. One DC24V signal switches the cylinder, saving manifold space and simplifying wiring for each diverter station.
Vertical Lift Station
Lifting heavy containers. The 100mm bore provides 3927 N push at 0.5 MPa, ideal for decentralized lift points where installing a remote valve is impractical.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X75S-08B the Right Choice?
When sizing, compare both directions against neighboring bores: this 100mm bore pushes 3927 N and pulls 3681 N at 0.5 MPa, while an 80mm bore pushes 2513 N. Confirm the DC24V coil and terminal entry match your control system. The rod retracts when energized, but you can reconfigure it to extend by repositioning the valve. Always size within the 0.15-0.8 MPa valve operating range, not the 1.0 MPa cylinder body rating. The integrated valve routes air but does not function as a load lock; for suspended loads, install an external rod lock or pilot-operated check valve. For strokes over 300mm, add external guidance 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-08B 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 DC24V. Although the cylinder body rates to 1.0 MPa, you must size force within the integrated valve's 0.15-0.8 MPa operating window.
No. The built-in 5/2 valve routes air but is not a load lock. If air is lost, the piston drifts. For suspended or held loads, add an external rod lock or a pilot-operated check valve. The default action retracts the rod when energized, but you can reposition the valve to extend on signal.
