Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 125mm 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 SAUF100X125-08A
The SAUF100X125-08A is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve. 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 has a 1/2" cylinder port, an M20x1.5 rod thread, and 29mm adjustable cushions.
Operating in the 0.15-0.8 MPa valve window, it delivers a 3927 N push at 0.5 MPa. The integrated valve provides a 1.4 Cv flow at a 1/4" port, cycling up to 4 times per second. For sizing, the safe working load is roughly 2356 N, and vertical lift is about 200 kg with a 2:1 margin. The AC220V terminal entry coil is IP65 rated. Note this SKU lacks the S suffix for a magnet, so it cannot take a magnetic switch.

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 SAUF100X125-08A Is Used
Decentralized Press Clamps
Actuate large clamping pins directly at the press station. The built-in valve removes long tube runs back to a central manifold.
Heavy Diverters
Drive heavy pallet diverters with a 3927 N push. One AC220V coil signal per actuator simplifies control wiring along the line.
Lift Gates
Lift lowerator gates up to 200 kg vertically. The integrated 4M310 valve handles the flow without needing a separate remote bank.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125-08A the Right Choice?
Size this 100mm bore against the 80mm and 100mm options using the 0.5 MPa figures (push 3927 N, pull 3681 N). Confirm the AC220V terminal entry and PT thread meet your control 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 window. The rod retracts by default when energized; reposition the valve to reverse this to extend-when-energised. Because the valve only routes air, it is not a load lock—add an external rod lock or pilot-operated check valve to hold a load. For this 125mm stroke side-load is minimal, but for any stroke over 300mm add a guide.
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 SAUF100X125-08A FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port and 1.4 Cv. The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit operates at 0.15-0.8 MPa.
No, the built-in valve only routes air and is not a lock. The rod retracts by default when energized but drifts on air loss. To hold a load securely, install an external rod lock or a pilot-operated check valve.
