Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X75-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X75-08B 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 SAUF100X75-08B
The SAUF100X75-08B 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 is shorter than an ISO 15552 cylinder of the same bore. This 100mm bore unit features a 1/2" cylinder port, an M20x1.5 rod thread, and 29mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers 3927N push force at 0.5 MPa. The integrated valve handles 1/4" ports with a Cv of 1.4 and cycles up to 4 times per second. A computed buyer insight suggests a safe working load around 2356N, enabling a vertical lift of roughly 200kg with a 2:1 margin. The DC24V terminal coil offers IP65 protection with a 0.05s response time.

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 SAUF100X75-08B Is Used
Heavy Press Clamping
Decentralized clamping on large press lines where routing a remote valve to a 100mm bore actuator would require excessive tubing and manifold capacity.
Pallet Diverter
Independent diverter arms on high-speed conveyors benefit from the built-in 4M310 valve, allowing localized control without a central manifold bank.
Vertical Lift Gate
Single-signal lifting of heavy material gates using the 200kg vertical lift capacity, saving installation time by integrating the valve directly on the cap.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X75-08B the Right Choice?
When sizing, compare this 100mm bore (3927N push at 0.5 MPa) against the 80mm neighbor (2513N) to ensure adequate force. The assembled unit must operate within the 0.15-0.8 MPa valve range, even though the cylinder body rates to 1.0 MPa. Confirm the DC24V terminal entry and PT threads meet your control specs. Because this SKU lacks the -S magnet suffix, it cannot accept a magnetic switch. The valve routes air but does not lock the load; add an external rod lock or pilot-operated check valve for hold requirements. Since the 75mm stroke is below the 300mm threshold, side-load guides are less critical, but always verify alignment. Default action retracts the rod when energized, but you can reposition the valve to extend on signal.
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 SAUF100X75-08B FAQ
It delivers 3927N push and 3681N pull at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4) running on DC24V. You must size force within the valve's 0.15-0.8 MPa operating window, not the cylinder body's 1.0 MPa limit.
No, the built-in valve only routes air and the cushions only decelerate; it is not a load lock, so the piston drifts without pressure. Add an external rod lock for holding. By default the rod retracts when the coil is energized, but you can reposition the valve to extend on signal.
