Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125S-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 125mm 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 SAUF100X125S-08B
The AirTAC SAUF100X125S-08B is a double-acting profile cylinder with a built-in 4M310-08 5/2 solenoid valve on the cap. One DC24V 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. This 100mm bore version has a 1/2" cylinder port, an M20x1.5 rod thread, and a 125mm stroke.
The integrated valve handles 0.15-0.8 MPa, so size force within that window rather than the 1.0 MPa cylinder body rating. At 0.5 MPa it delivers 3927N push force, giving a computed safe working load of roughly 2356N or a 200kg vertical lift with a 2:1 margin. The valve port is 1/4" with a Cv of 1.4, cycling up to 4 times per second. 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 SAUF100X125S-08B Is Used
Decentralized Press Clamping
Uses the integrated 4M310-08 valve to clamp heavy parts directly at the press station without running long tubing back to a central manifold.
Inline Divert Gate
Provides a self-switching diverting motion on a high-speed conveyor, operating up to 4 cycles per second with a single DC24V signal.
Pallet Stopper Arm
Acts as a robust stopping arm for heavy pallets, leveraging the 100mm bore's 3927N push force at 0.5 MPa right at the conveyor lane.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125S-08B the Right Choice?
When sizing, compare both ways: the 80mm bore neighbor offers 2513N push at 0.5 MPa, while the 100mm bore here provides 3927N. Confirm the DC24V terminal entry and PT threads meet your control spec. The rod retracts by default when energized, but you can reconfigure it to extend by repositioning the valve. Always operate within the 0.15-0.8 MPa valve range. The valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. Since the 125mm stroke is below the 300mm threshold, side-load guides are less critical but still good practice.
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 SAUF100X125S-08B FAQ
It generates 3927N push and 3681N pull at 0.5 MPa, reaching 6282N push at 0.8 MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port and Cv of 1.4, running on DC24V. You must size the force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
Yes, the default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the integrated valve. The valve only routes air; it is not a load lock. If you need to hold a load during air loss, install an external rod lock or pilot-operated check valve.
