Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125S-08A 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-08A
The SAUF100X125S-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 125 mm stroke is above the 75 mm SAUF minimum, and the piston rod is Ø25 mm with an M20x1.5 thread and 1/2" cylinder port.
The integrated valve has a 1/4" port, 25 mm2 flow (Cv 1.4), and runs at 4 cycles/sec. The coil is AC220V with terminal entry and IP65 protection. Size force within the valve's 0.15-0.8 MPa window, not the 1.0 MPa cylinder body rating. At 0.5 MPa it pushes 3927 N and pulls 3681 N. A computed buyer insight gives a safe working load of roughly 2356 N (60% of the 0.5 MPa push), ideal for a vertical lift up to 200 kg with a 2:1 margin. 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)

|---|---|---|
| 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-08A Is Used
Machine Tool Clamping
Decentralized clamping on a large CNC where running a 1/2" port cylinder from a remote manifold is impractical; the built-in 4M310 valve switches the clamp from one AC220V signal.
Heavy Diverter Gate
Actuating a high-force diverter on a packaging line. The integrated valve saves tubing across the frame, and the 3927 N push at 0.5 MPa handles heavy product flow.
Vertical Lift Station
Lifting pallets or totes in an automated store. The magnet allows position sensing, and the unit safely lifts around 200 kg vertically with a 2:1 margin at 0.5 MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X125S-08A the Right Choice?
When sizing, compare this 100 mm bore against the 80 mm neighbor: the 80 mm pushes 2513 N versus 3927 N here at 0.5 MPa. Confirm the AC220V terminal entry and 1/4" valve port match your supply. The cylinder body rates to 1.0 MPa, but the assembled unit must operate in the 0.15-0.8 MPa valve range. Default action retracts the rod when energised; reposition the valve to extend on signal. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold a load. For this 125 mm stroke side-load is minimal, but always guide the rod for strokes over 300 mm.
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-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" port, Cv 1.4, 4 cycles/sec) driven by an AC220V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate in the 0.15-0.8 MPa valve window.
By default the rod retracts when the coil receives the AC220V signal. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This self-switching design removes the need for a remote valve, saving a manifold slot and tubing.
