Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400S-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 SAUF100X400S-08B
The SAUF100X400S-08B is a double-acting profile-type 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 makes it shorter than an ISO 15552 cylinder of the same bore. It features a 100mm bore, 400mm stroke, and a 1/2" cylinder port.
Operating within the valve's 0.15-0.8 MPa window, it delivers 3927N push force at 0.5 MPa. A computed buyer insight: safe working load is roughly 2356N (60% of the 0.5MPa push), allowing a 200kg vertical lift with a 2:1 margin. The integrated 4M310-08 valve has a 1/4" port, Cv 1.4, and runs up to 4 cycles/s. This DC24V terminal-entry coil is IP65 rated, and the S suffix denotes a piston magnet for CMSG/DMSG/EMSG 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 SAUF100X400S-08B Is Used
Decentralized Press Clamps
Actuate heavy clamping stations individually without routing long tube runs back to a central manifold.
Inline Diverters
Switch heavy product diverters directly at the conveyor lane using one DC24V signal per actuator.
Vertical Lift Gates
Lift material handling gates up to 200kg with a 2:1 safety margin, saving manifold space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400S-08B the Right Choice?
Size force between the 0.15-0.8 MPa valve limits: this 100mm bore pushes 3927N at 0.5MPa, whereas the neighbouring 80mm bore pushes 2513N. Confirm the DC24V terminal entry and PT threads match your supply. The rod retracts when energised; reposition the valve to extend-when-energised. The built-in valve routes air but is not a lock—add an external rod lock or pilot-operated check valve to hold loads. 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 SAUF100X400S-08B FAQ
It pushes 3927N and pulls 3681N at 0.5MPa, reaching 6282N at 0.8MPa. The built-in 4M310-08 valve has a 1/4" port, Cv 1.4, and a DC24V IP65 coil. Size the force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
No. The integrated 5/2 valve routes air but does not lock the piston. The rod retracts by default when energised, and you can reposition the valve to extend-when-energised. For load holding on air loss, install an external rod lock or pilot-operated check valve.
