Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350S-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 350mm stroke and a built-in 4M210-08 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 SAUF32X350S-08B
The SAUF32X350S-08B is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 32mm bore uses a 1/8" cylinder port, a Ø12mm rod with an M10x1.25 thread, and 21mm adjustable cushions.
Driven by a DC24V terminal-entry coil (IP65, 30-800mm/s speed), the integrated 4M210-08 valve offers 1/4" porting, Cv 0.89, and 5 cycles/sec. The cylinder body rates to 1.0MPa, but the valve limits operation to 0.15-0.8MPa. Push force is 402N at 0.5MPa. A computed buyer insight: safe working load is roughly 241N (60% of the 0.5MPa push), enabling a 20kg vertical lift with a 2:1 margin. The S suffix denotes a piston magnet 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 (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 SAUF32X350S-08B Is Used
Decentralized Clamping
Ideal for distributed clamping stations on a large fixture, using the built-in valve to actuate locally without routing long tubing back to a central manifold.
Inline Diverting
Drives a 350mm diverting gate on a conveyor line. The integrated 4M210 valve provides rapid 5 cycle/sec shifting right at the actuator.
Component Push-off
Ejects machined parts from a cell. The DC24V coil switches the 32mm bore locally, saving manifold space while delivering 402N push at 0.5MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350S-08B the Right Choice?
Size force within the 0.15-0.8MPa valve window: this 32mm bore pushes 402N and pulls 345N at 0.5MPa. If you need less force, no smaller SAUF bore exists; for more power, step up to the 40mm bore (628N push at 0.5MPa). Confirm the DC24V terminal entry and PT threads suit your controls. The rod retracts when the coil is energised; reposition the valve to extend-when-energised. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve for load holding. At 350mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF32X350S-08B FAQ
It pushes 402N and pulls 345N at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) driven by a DC24V terminal-entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within the valve's 0.15-0.8MPa range.
By default, the rod retracts when the coil is energised; you can reposition the valve to extend-when-energised. The valve only routes air, so it is not a load lock. On air loss, the piston drifts and the 21mm cushion merely decelerates near stroke end—add an external rod lock or pilot-operated check valve for true load holding.
