Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125S-06B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 125mm stroke and a built-in 4M210-06 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 SAUF32X125S-06B
The AirTAC SAUF32X125S-06B is a double-acting profile cylinder with a built-in 4M210-06 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 cylinder of the same bore. This 32mm bore unit has a 1/8" cylinder port, M10x1.25 rod thread, and a 125mm stroke. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
Operating on DC24V with terminal entry, the integrated valve provides 14 mm2 flow (Cv 0.78) and handles up to 5 cycles/sec. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa working window. At 0.5 MPa it pushes 402 N and pulls 345 N. A practical computed insight: the safe working load is roughly 241 N (about 60% of the 402 N figure), translating to a vertical lift capacity of approximately 20 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 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 SAUF32X125S-06B Is Used
Decentralized Clamping
Ideal for small part clamping stations where running a remote valve manifold would waste tubing and install time.
Package Diverting
Provides one-signal actuation for a sorting gate on a conveyor, saving manifold space while handling light loads.
Compact Ejection
Fits neatly into tight machine cells for ejecting machined parts using the built-in 4M210-06 valve.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125S-06B the Right Choice?
Size this 32mm bore against the neighboring 40mm option, which pushes 628 N at 0.5 MPa. This SAUF32X125S-06B pushes 402 N at 0.5 MPa, peaking at 643 N at the 0.8 MPa valve limit. Confirm the DC24V coil and terminal entry suit your control panel. The rod retracts when the coil energizes; reposition the valve to reverse this to extend-when-energized. The integrated valve routes air but does not lock the piston—add an external rod lock or pilot-operated check valve to hold loads safely. For this 125mm stroke, side-load is minimal, but always guide the rod for longer strokes above 300mm.
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 SAUF32X125S-06B FAQ
It generates 402 N push and 345 N pull at 0.5 MPa, reaching 643 N push at 0.8 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max). It runs on DC24V with terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa range.
By default, the rod retracts when the coil is energized. You can reconfigure it to extend-when-energized by repositioning the valve. The valve only routes air; it is not a load lock. If air is lost, the piston will drift, so use an external rod lock or pilot-operated check valve for load holding.
