Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X350S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X350S-08A 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 SAUF100X350S-08A
The SAUF100X350S-08A is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on its cap. One coil signal drives the actuator, eliminating remote valves and saving a manifold slot. The hard-anodized aluminum barrel is shorter than an ISO 15552 unit of the same bore. This 100mm bore has a 1/2 inch cylinder port, a 25mm rod, and a 29mm adjustable cushion. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
Operating on AC220V (terminal entry, IP65), the integrated valve handles 4 cycles/sec with a 1/4 inch port and Cv 1.4. The cylinder body rates to 1.0 MPa, but the assembled SAUF must run within the valve's 0.15-0.8 MPa window. At 0.5 MPa it pushes 3927 N and pulls 3681 N. For sizing, the safe working load is roughly 2356 N (60% of the 0.5 MPa push), and it can vertically lift 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 SAUF100X350S-08A Is Used
Machine Tool Clamping
Decentralized clamping on a large machining center. The built-in valve switches this 100mm bore directly from one coil signal, saving manifold space and tubing runs.
Heavy Transfer Diverters
Actuating heavy diverter arms on a packaging line. The 4M310-08 valve delivers Cv 1.4 flow for rapid 350mm strokes without a remote valve bank.
Pallet Lift Stations
Lifting pallets in localized zones. The vertical lift capacity is about 200 kg with a 2:1 margin, driven entirely by the integrated AC220V solenoid.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X350S-08A the Right Choice?
Size by force: the 100mm bore gives 3927 N push at 0.5 MPa; step down to an 80mm bore for 2513 N, or up if you exceed 6282 N at 0.8 MPa. Always size within the 0.15-0.8 MPa valve limit, never the 1.0 MPa cylinder rating. Confirm the AC220V terminal entry matches your control voltage. The rod retracts when the coil is energised; reposition the valve to extend-when-energised. The built-in valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold a load. For this 350mm stroke, use external guides to prevent rod bending and side loads.
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 SAUF100X350S-08A FAQ
It uses a 4M310-08 5/2 valve with a 1/4 inch port and Cv 1.4. The coil is AC220V with terminal entry. Push force is 3927 N and pull is 3681 N at 0.5 MPa, reaching 6282 N at 0.8 MPa. You must size within the built-in valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
No. The built-in valve only routes air; it is not a load lock. If air is lost or the valve is centered, the piston drifts and the 29mm cushion only decelerates near stroke end. For load holding, install an external rod lock or a pilot-operated check valve.
