Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400S-08A 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-08A
The SAUF100X400S-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, saving tubing and a manifold slot in decentralized setups. The 100mm bore delivers 3927N push and 3681N pull at 0.5MPa. The cylinder body rates to 1.0MPa, but the integrated valve limits the assembled working pressure to 0.15-0.8MPa.
This unit uses a 1/4" valve port with 25mm2 flow (Cv 1.4) and switches up to 4 cycles/sec. The AC220V terminal-entry coil is IP65 rated. Computed buyer insight: safe working load is roughly 2356N (60% of the 0.5MPa push), and vertical lift capacity is about 200kg with a 2:1 margin. The 1/2" cylinder port and M20x1.5 rod thread handle high flow. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG 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-08A Is Used
Heavy Material Lift
Lifts 200kg vertical loads in decentralized cells using one AC220V signal, saving a manifold slot.
Press Clamping Station
Provides 3927N clamping force at 0.5MPa with a built-in 4M310 valve for standalone press modules.
Pallet Stopper Gate
Actuates heavy 400mm stroke stopper gates directly on the conveyor frame without remote plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400S-08A the Right Choice?
Size by checking both neighbors: the 80mm bore gives 2513N push at 0.5MPa, while this 100mm bore yields 3927N. Confirm the AC220V terminal entry matches your supply. Default action retracts the rod when energized; reposition the valve to extend-when-energized. Size force within the 0.15-0.8MPa valve window, never the 1.0MPa cylinder body rating. The 4M310 valve routes air but does not lock the piston—add an external rod lock or pilot-operated check valve to hold loads. For the 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-08A FAQ
It pushes 3927N and pulls 3681N at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 4 cycles/sec max) driven by an AC220V terminal-entry coil. The cylinder body rates to 1.0MPa, but the assembled unit must operate within the valve's 0.15-0.8MPa window.
Yes. The default action retracts the rod on energization, but you can reposition the built-in valve to make it extend-when-energized. This 5/2 valve routes air to switch directions; it is not a load lock, so add an external rod lock if you need to hold a load.
