Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400S-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400S-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 SAUF100X400S-10A
The SAUF100X400S-10A 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 cylinder of the same bore. The bore dictates a 1/2" cylinder port and an M20x1.5 rod thread.
The integrated 4M310-10 valve has a 3/8" port, Cv 1.68, and cycles up to 4 times per second. The AC220V terminal-entry coil is IP65 rated. The cylinder body rates to 1.0 MPa, but the assembled unit operates at 0.15-0.8 MPa. At 0.5 MPa it pushes 3927 N, giving a safe working load of roughly 2356 N or a 200 kg vertical lift with a 2:1 margin. The S suffix adds a piston magnet for position switches.

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 SAUF100X400S-10A Is Used
Pallet Divertor
Decentralized diverting arm on a high-flow line. The 4M310 valve delivers Cv 1.68 directly at the cap, moving the 400 mm stroke without long tube runs back to a main manifold.
Heavy Gate Actuator
Opening large access doors on automated storage systems. The 100 mm bore provides 3927 N push at 0.5 MPa, and the built-in AC220V coil removes the need for a remote valve island.
Press Ejector
Ejecting finished parts from a large press. The piston magnet supports CMSG switches for position confirmation, while the profile barrel saves machine space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400S-10A the Right Choice?
Size force within the 0.15-0.8 MPa valve window: this 100 mm bore pushes 3927 N at 0.5 MPa, while the smaller 80 mm bore pushes 2513 N. Confirm the AC220V terminal entry and PT threads match your supply. The rod retracts when the coil is energised but can be reconfigured to extend by repositioning the valve. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For the 400 mm 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 SAUF100X400S-10A FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa, reaching 6282 N at 0.8 MPa. The built-in valve is a 4M310-10 with a 3/8" port and Cv 1.68. The cylinder body rates to 1.0 MPa, but the assembled unit operates strictly at 0.15-0.8 MPa. The coil is AC220V with terminal entry.
No. The built-in 5/2 valve routes air but is not a lock. If air is lost, the piston drifts and the 29 mm cushions only decelerate near stroke end. To hold a load, install an external rod lock or pilot-operated check valve.
