Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X225S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X225S-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 225mm 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 SAUF100X225S-08A
The SAUF100X225S-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 bore 100 body has a 1/2 inch cylinder port, a 25 mm rod, and 29 mm adjustable cushions. This unit includes a piston magnet for position sensing.
It delivers 3927 N push at 0.5 MPa within the 0.15-0.8 MPa valve operating window. The integrated valve has a 1/4 inch port, Cv 1.4 flow, and runs up to 4 cycles per second. Computed buyer insight: safe working load is roughly 2356 N, and vertical lift is about 200 kg 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 SAUF100X225S-08A Is Used
Heavy Press Clamping
Decentralized clamping on a large press line. One AC220V signal actuates the 100 mm bore directly at the fixture without remote plumbing.
Pallet Diverter
A standalone diverter arm on a high-capacity conveyor. The built-in 4M310 valve handles the 225 mm stroke without needing a central manifold.
Vertical Lift Gate
Lifting a 200 kg material gate. The integrated valve saves install time, while the piston magnet supports end-of-stroke confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X225S-08A the Right Choice?
Size both ways: the 100 mm bore gives 3927 N push at 0.5 MPa, while the smaller 80 mm bore gives 2513 N. Confirm the AC220V terminal entry and PT thread before ordering. The cylinder body rates to 1.0 MPa, but size force within the 0.15-0.8 MPa valve limit. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. Default action retracts when energised, but repositioning the valve extends it. The 225 mm stroke is above the 75 mm minimum and under 300 mm, so side-load guides are less critical.
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 SAUF100X225S-08A 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 4M310-08 (1/4 inch port, Cv 1.4) running on AC220V. Size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating.
By default the rod retracts when energised. You can reconfigure it to extend when energised by repositioning the built-in valve. This means one coil signal switches the cylinder directly, eliminating the need for a separate remote valve.
