Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X300S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X300S-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 300mm 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 SAUF100X300S-08A
The SAUF100X300S-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, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
This 100mm bore delivers 3927N push at 0.5MPa within the valve's 0.15-0.8MPa working window. The 4M310-08 valve has a 1/4" port, Cv 1.4, and cycles up to 4 times per second. The cylinder port is 1/2". Computed buyer insight: safe working load is roughly 2356N (60% of the 0.5MPa push), offering a 200kg vertical lift capacity 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 SAUF100X300S-08A Is Used
Heavy Press Stand
Decentralized pressing station using one coil signal per actuator, avoiding a central manifold and long tubing runs for high-force operations.
Pallet Diverter
Independent lane routing on a conveyor line where installing a separate remote valve for each cylinder is impractical or wastes space.
Vertical Gate Actuator
Lifting heavy access gates directly at the point of use, leveraging the 200kg vertical lift capacity and saving manifold slots.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X300S-08A the Right Choice?
Size by checking both neighbours: the 80mm bore pushes 2513N at 0.5MPa, while this 100mm bore pushes 3927N at 0.5MPa. Confirm the AC220V terminal entry and PT thread before ordering. The cylinder body rates to 1.0MPa, but you must size force within the built-in valve's 0.15-0.8MPa limit. The rod retracts by default when energised, but you can reposition the valve to extend on signal. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold a load. For this 300mm stroke, use external guides to prevent rod bending from side loads.
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 SAUF100X300S-08A FAQ
It pushes 3927N and pulls 3681N at 0.5MPa, reaching 6282N at 0.8MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec). The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0MPa, the assembled unit operates at 0.15-0.8MPa.
The default action retracts the rod when energised. You can reconfigure it to extend when energised by repositioning the built-in valve. This self-switching design means no remote valve is needed, though the valve only routes air and is not a load lock.
