Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X350-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X350-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 350mm 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 SAUF100X350-08B
The SAUF100X350-08B 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 cylinder, saving a manifold slot and tubing. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore.
This 100mm bore model delivers a push force of 3927N at 0.5MPa, scaling to 6282N at the 0.8MPa assembled max. The integrated valve offers a 1.4 Cv flow at 1/4" port, cycling up to 4 times per second. Computed buyer insight: safe working load is roughly 2356N (60% of the 0.5MPa push), allowing a vertical lift of about 200kg with a 2:1 margin. The cylinder port is 1/2".

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 SAUF100X350-08B Is Used
Heavy Press Clamping
Decentralized clamping on a large press line. The built-in valve provides immediate local actuation without routing long tubing back to a central manifold.
Pallet Diverter
Diverting heavy pallets on a conveyor. One coil signal switches the 100mm bore directly, delivering high push force exactly where needed.
Automated Lift Gate
Lifting materials at a packaging cell. The integrated 4M310 valve handles the 350mm stroke efficiently, saving manifold space for other actuators.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X350-08B the Right Choice?
Size against the 63mm and 80mm neighbours: this 100mm bore provides 3927N push at 0.5MPa versus 2513N for the 80mm. Confirm the DC24V terminal entry and PT thread. The default action retracts the rod when energised; reposition the valve to extend on energise. Size force within the 0.15-0.8MPa valve window, not the 1.0MPa cylinder body rating. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads. For the 350mm stroke, use external guides to prevent rod bending and side-load wear. This SKU lacks a magnet and cannot take a sensor.
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 SAUF100X350-08B FAQ
It pushes 3927N and pulls 3681N at 0.5MPa, reaching 6282N push at 0.8MPa. 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 0.15-0.8MPa operating window, even though the cylinder body rates to 1.0MPa.
The built-in valve routes air; it is not a lock, so the piston drifts on air loss. Add an external rod lock or pilot-operated check valve to hold a load. By default the rod retracts when the coil is energised, but you can reposition the valve to extend when energised.
