Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400-10A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 400mm stroke and a built-in 4M310-10 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 SAUF100X400-10A
The AirTAC SAUF100X400-10A is a double-acting profile cylinder with a built-in 4M310 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, 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 has a 1/2" cylinder port, a 3/8" valve port, and a 400mm stroke.
Operating within the valve's 0.15-0.8 MPa window, it generates 3927 N push force at 0.5 MPa. The integrated 4M310-10 valve provides 30 mm2 flow (Cv 1.68) and handles up to 4 cycles per second. For sizing, the safe working load is roughly 2356 N, and it can vertically lift about 200 kg with a 2:1 margin. Note this SKU lacks a magnet, so it cannot accept 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 SAUF100X400-10A Is Used
Heavy Press Clamping
Decentralized clamping on a large press line. The integrated valve switches the 100mm bore directly at the station, eliminating long tube runs from a central manifold.
Pallet Diverting
A single coil signal actuates the diverter arm. The 4M310 valve provides high flow for rapid 400mm strokes, keeping cycle times tight without a remote valve bank.
Material Lift Gate
Ideal for independent lift gates in a sorting hub. The self-contained pneumatic unit simplifies installation and saves manifold slots while lifting heavy fixtures.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400-10A the Right Choice?
When sizing, compare neighboring bores: the 80mm bore yields 2513 N push at 0.5 MPa, while this 100mm bore yields 3927 N. Confirm the AC220V terminal entry and PT thread before ordering. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because the built-in valve only routes air, add an external rod lock or pilot-operated check valve for load holding. For this 400mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF100X400-10A FAQ
It uses a built-in 4M310-10 valve (3/8" port, Cv 1.68, 4 cycles/sec max) with an AC220V terminal entry coil. The 100mm bore pushes 3927 N at 0.5 MPa and 6282 N at 0.8 MPa. You must size within the valve's 0.15-0.8 MPa operating window, as the 1.0 MPa cylinder body rating exceeds the valve limit.
No. The built-in 5/2 valve routes air but is not a load lock. If air is lost, the piston drifts and the 29mm cushions only decelerate near stroke end. Install an external rod lock or pilot-operated check valve for secure load holding. You can also reposition the valve to switch from retract-when-energized to extend-when-energized.
