Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300S-06B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 300mm 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 SAUF32X300S-06B
The SAUF32X300S-06B is a double-acting profile cylinder with a built-in AirTAC 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 DC24V terminal-entry unit has a 1/8" valve port and a 1/8" cylinder port.
Size force within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it pushes 402 N and pulls 345 N. The safe working load is roughly 241 N (about 60% of the 402 N figure), offering a vertical lift capacity of about 20 kg with a 2:1 margin. The valve flows 14 mm2 (Cv 0.78) at up to 5 cycles 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 (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 SAUF32X300S-06B Is Used
Decentralized Clamping Stations
Ideal for multi-station clamping where running individual lines to a central manifold is impractical, saving tubing and installation time.
Independent Diverter Gates
Mount directly on a conveyor diverter arm. The integrated 4M210-06 valve provides fast 5 cycle/sec actuation without a remote valve bank.
Compact Machine Ejectors
Fits space-constrained ejector mechanisms. The profile barrel is shorter than standard cylinders, and the built-in valve frees up manifold space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300S-06B the Right Choice?
When sizing, compare both ways: against the 40 mm bore (628 N push at 0.5 MPa) or the smaller options. Confirm the DC24V coil, terminal entry, and PT threads match your control scheme. The rod retracts when the coil energises, but you can reposition the valve to extend-when-energised. Always operate within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder rating. Because the 300 mm stroke exceeds 300 mm, add external guides to prevent rod bending and side-load wear. The built-in valve routes air; it does not lock the load. For suspended loads, install an external rod lock or pilot-operated check valve to prevent drift on air loss.
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 SAUF32X300S-06B FAQ
It generates 402 N push and 345 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 14 mm2 flow) running on a DC24V coil. Although the cylinder body rates to 1.0 MPa, you must size force within the assembled valve's 0.15-0.8 MPa operating window. The cylinder port is 1/8".
No. The integrated 5/2 valve routes air but is not a load lock. If air is lost, the piston drifts. For load holding, add an external rod lock or pilot-operated check valve. Note the rod retracts by default when energised, but you can reposition the valve to extend-when-energised.
