Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X450-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X450-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 450mm 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 SAUF100X450-08A
The SAUF100X450-08A 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, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. It features a 100mm bore, 450mm stroke, 1/2" cylinder port, M20x1.5 rod thread, and 29mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers 3927 N push force at 0.5 MPa. The 4M310-08 valve has a 1/4" port, Cv 1.4 flow, and 4 cycles/s. The AC220V terminal coil is IP65 rated. For sizing, the safe working load is roughly 2356 N (60% of the 0.5 MPa push), allowing a 200 kg vertical lift with a 2:1 margin. This SKU lacks a magnet and cannot take sensors.

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 SAUF100X450-08A Is Used
Machine Tool Clamping
Decentralized clamping on a large machining center, using one coil signal per station to eliminate a central manifold.
Heavy Transfer Diverters
Actuating heavy divert gates on a conveyor line where installing remote valves and long tubing runs is impractical.
Pallet Lift Stations
Lifting pallets in independent zones, leveraging the 200 kg vertical lift capacity with a 2:1 safety margin.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X450-08A the Right Choice?
Size between neighbours: the 80mm bore gives 2513 N push at 0.5 MPa, while this 100mm bore gives 3927 N. Confirm the AC220V terminal entry and PT thread. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. Size force within the 0.15-0.8 MPa valve limit, never the 1.0 MPa cylinder body rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For the 450mm stroke, use external guides to prevent rod bending and side loads. Without a magnet, this version cannot accept switches.
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 SAUF100X450-08A FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa, reaching 6282 N at 0.8 MPa. The built-in 4M310-08 valve has a 1/4" port, Cv 1.4, and runs on AC220V. You must size force within the valve's 0.15-0.8 MPa window, not the 1.0 MPa cylinder body rating.
Yes, the default action retracts the rod when energised, but you can reposition the valve to extend on signal. The valve only routes air; it is not a load lock. For load holding on air loss, install an external rod lock or pilot-operated check valve.
