Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 400mm 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 SAUF100X400-08B
The SAUF100X400-08B 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. This SKU has no magnet, so it cannot take a magnetic switch.
The 100mm bore delivers 3927N push and 3681N pull at 0.5MPa. The integrated valve has a 1/4" port, Cv 1.4, and runs at 4 cycles/sec. The cylinder body rates to 1.0MPa, but you must size force within the valve's 0.15-0.8MPa window. Based on the 0.5MPa push force, the safe working load is roughly 2356N, yielding a vertical lift capacity of about 200kg 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 SAUF100X400-08B Is Used
Heavy Press Station
Decentralized actuation for a stamping press. The built-in 4M310 valve handles the 100mm bore directly at the station, removing long tube runs from a central manifold.
Pallet Lift Unit
Lifting heavy pallets in a packaging line. The 100mm bore provides 3927N push at 0.5MPa, and the single coil signal simplifies control wiring.
Sorting Diverter
Diverting heavy products on a conveyor. The integrated valve switches the 400mm stroke actuator locally, saving manifold slots and reducing response delays.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400-08B the Right Choice?
When sizing, compare neighboring bores: the 80mm bore offers 2513N push while the 100mm bore provides 3927N push at 0.5MPa. This DC24V terminal entry coil (IP65) defaults to retract-when-energized but can be reconfigured to extend-when-energized by repositioning the valve. Always operate within the 0.15-0.8MPa valve range, never the 1.0MPa cylinder body rating. The built-in valve routes air and is not a lock; the piston will drift on air loss, so add an external rod lock or pilot-operated check valve for held loads. For the 400mm stroke, use external guides to prevent rod bending and side-load wear. The cylinder port is 1/2" and the PU tube is Ø10xØ6.5.
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 SAUF100X400-08B FAQ
It delivers 3927N push and 3681N pull at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4) running at max 4 cycles/sec. The coil is DC24V with terminal entry. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
No, the built-in valve routes air and is not a load lock; the piston drifts on air loss and the cushion only decelerates near stroke end. Add an external rod lock or pilot-operated check valve for holding. By default the rod retracts when the coil is energized, but you can reconfigure it to extend-when-energized by repositioning the valve.
